Prepared Remarks:
Operator
Thank you for standing by, and welcome to the WEX Q4 2023 earnings call. I would now like to welcome Steve Elder, SVP of global investor relations, to begin the call. Steve, over to you.
Steve Elder -- Senior Vice President, Global Investor Relations
Thank you, operator, and good morning, everyone. With me today is Melissa Smith, our chair and CEO; and Jagtar Narula, our CFO. The press release we issued earlier this morning and a slide deck to walk through our prepared remarks have been posted to the investor relations section of our website at wexinc.com. A copy of the release has also been included in an 8-K we filed with the SEC earlier this morning.
As a reminder, we will be discussing non-GAAP metrics, specifically adjusted net income attributable to shareholders, which we refer to as adjusted net income or ANI, adjusted operating income and related margins, as well as adjusted free cash flow during our call. Please see Exhibit 1 of the press release for an explanation and reconciliation of these non-GAAP measures. The company provides revenue guidance on a GAAP basis and earnings guidance on a non-GAAP basis due to the uncertainty and the indeterminate amount of certain elements that are included in reported GAAP earnings. I would also like to remind you that we will discuss forward-looking statements under the Private Securities Litigation Reform Act of 1995.
Should you invest $1,000 in Wex right now?
Before you buy stock in Wex, consider this:
The Motley Fool Stock Advisor analyst team just identified what they believe are the 10 best stocks for investors to buy now… and Wex wasn’t one of them. The 10 stocks that made the cut could produce monster returns in the coming years.
Stock Advisor provides investors with an easy-to-follow blueprint for success, including guidance on building a portfolio, regular updates from analysts, and two new stock picks each month. The Stock Advisor service has more than tripled the return of S&P 500 since 2002*.
*Stock Advisor returns as of February 5, 2024
Actual results may differ materially from those forward-looking statements as a result of various factors, including those discussed in our press release and the risk factors identified in our annual report on Form 10-K for the year ended December 31, 2022, filed with the SEC on February 28, 2023; and in our quarterly reports on Form 10-Q; and subsequent SEC filings. While we may update forward-looking statements in the future, we disclaim any obligations to do so. You should not place undue reliance on these forward-looking statements, all of which speak only as of today. With that, I'll turn the call over to Melissa.
Melissa Smith -- Chief Executive Officer
Thank you, Steve, and good morning, everyone. We appreciate you joining us today. Before diving into our results, I'd like to take a moment to reflect on 2023. As I've said in prior quarters, our business model is resilient and it delivers strong results in a variety of environments.
This is true over the past 10 years. During which time, we have delivered a revenue CAGR of 14%. I am very proud of what we've accomplished in 2023 as we continue to achieve our long-term growth targets despite macroeconomic uncertainty, higher interest rates, higher inflation rates, a freight recession, and lower fuel prices. Our incredible team of Wexters has consistently risen to the occasion, further positioning WEX for long-term success and demonstrating our ability to grow, to deliver that growth profitably, and to advance our strategic priorities.
Let me start with the full year results. Revenue of $2.5 billion for the year was a new record high and grew 8% compared to the prior year despite a headwind of 5% from fuel prices and foreign exchange rates. Full year total volume processed was $225 billion, an increase of 6% year over year. Adjusted net income per share grew 9% year over year.
Excluding the impact of lower fuel prices and foreign exchange rate differences, revenue grew 13% and adjusted net income per share grew 21%. Both of these growth rates were within or above our long-term target ranges as we continue to deliver strong results in the face of the headwinds I just mentioned. I'm particularly pleased about the strong performance in benefits and corporate payments, which further demonstrates the resilience of our model across many environments. Now, turning to fourth quarter results.
We delivered revenue of $663 million for the quarter, an increase of 7%. Excluding the impact of fluctuations in fuel prices and foreign exchange rates, Q4 revenue grew 11%. Total volume processed across the organization in the fourth quarter grew 6% year over year to $56 billion, driven by the strong performance in corporate payments and benefits. Strong quarterly revenue, high margin drop-through in volumes, and share repurchases resulted in adjusted net income per diluted share of $3.82, an increase of 11% compared to the same quarter last year.
Excluding the impact of fluctuations in fuel prices and foreign exchange rates, Q4 adjusted EPS grew 23%. In corporate payments, purchase volumes grew 33% year over year, primarily due to continued strength from our travel customers. We had a number of significant contract renewals in the quarter, including Kiwi and On the Beach in Europe and Flight Centre in Australia. WEX continues to outpace the growth of the travel market.
We're having success gaining additional pockets of spend within our existing customer base, and volume growth continue to benefit from the market transition to settling hotel transactions with virtual cards. In the benefits segment, the full transition to the public cloud positions us to improve our agility and platform strength going forward. Following open enrollment, we now have more than 8 million HSA accounts on our platform, making us one of the largest providers in the country. Since we closed the acquisition of Ascensus' health and benefits line of business in September, we have quickly integrated our teams.
Ascensus' technology complements ours well, increasing our scale in the benefits space and expanding our benefit product offerings with their Affordable Care Act compliance and dependent verification capabilities. Finally, in our mobility segment, we continue to see the positive impact from our enhanced credit policies. We were also pleased with strong sales performance, including a number of key contracts wins and renewals in the quarter, adding approximately 121,000 new vehicles and signing wins with Smith Transport, Estes Express Lines, Quality Carriers, and PODS, to name a few. Overall, I'm proud of the strong progress we made executing against our strategic themes throughout 2023, which positions us for success in 2024 and beyond.
A top priority for us as a company is leading in the energy transition for our mobility customers. Currently, we're focused on helping businesses navigate the energy transition and manage their vehicles in an increasingly complex mixed fleet world. With over 600,000 customers worldwide, including more than 19.3 million vehicles serviced globally as of the fourth quarter, our partners and customers will first look to WEX for helping simplifying the process of building and managing mixed fleets. While the pace of transition remains fluid, we are meeting our customers where they are in their EV journeys.
As part of our EV product fleet, we have a new white-labeled offering to help fleet managers determine which vehicles and routes may make sense to transition to EVs. In cases where it does make sense like a sales rep driving a sedan and returning home to charge at night, there can be substantial savings for the fleet operator. Our understanding of these dynamics uniquely positions WEX to help customers both navigate the decision to transition and effectively manage their fleets once they do. We've also launched products in the market designed to help facilitate en-route charging at public locations, as well as at-home reimbursement capabilities.
Later this year, we plan to launch depot charging solutions for companies that intend to use their own infrastructure. Our EV product suite gives our customers a simple consolidated platform for mixed fleets, greatly simplifying the job of the fleet manager. Similar to the EV transition, a strategic priority has been to expand into near adjacent addressable markets, increasing our TAM. In November, we completed our acquisition of Payzer, a leading cloud-native field service management software.
As we integrate Payzer into the WEX business, we expect the platform to strengthen our relationships with customers in our mobility vertical, allowing us to match our world-class payment capabilities with integrated software that creates durable value to our customer base. We're excited to deepen and expand our offerings to approximately 150,000 mobility customers that operate field service management companies. So far, we have completed the initial stage of integration and launched our first marketing efforts targeted at current WEX customers. Over the next few quarters, we will test and learn from this initiative and we will continue to be prudent in our decisions to allocate additional capital to this effort.
That said, we're excited about the Payzer opportunity, and I look forward to providing updates on our progress going forward. Across each of our businesses, we are focused not only on driving growth but on delivering that growth profitably. To that end, we remain well sufficient to generate $100 million in run rate cost savings exiting 2024. Last quarter, we said we're on track to achieve $75 million of cost savings on a run rate basis by the end of 2023.
I am proud to say we have accomplished this goal, which was ahead of our original expectations. We have high confidence in achieving the full $100 million of cost savings in 2024. With these savings, we plan to let half flow through to earnings, which we'll see in our expectations for 2024; and reinvest the remainder in the business to enhance our capabilities, including digital products, technology, and risk management capabilities and tools. We also continue to drive technology innovation throughout the business.
The work we are doing is delivering results, and we're seeing cost savings coming through our margins. In 2023, we focused heavily on determining how AI could both optimize our business and the business of our customers. We've invested in dozens of projects around developing these capabilities. For example, we're currently using internally developed AI technology to assist in making credit decisions and detecting fraud.
We believe this technology helped drive the substantial credit loss improvement that we have seen over the last two quarters. We're also piloting several new initiatives to enhance productivity and drive efficiencies in our sales teams by using AI to prioritize the leads most likely to convert and by prioritizing deals in the sales pipeline to maximize focus on impactful deals. We are also using AI to help process benefit claims, which drives efficiency and improves customer experience by processing claims on the same day. We processed greater than 350,000 claims last year and continue to expand use cases.
We expect to process more than 800,000 claims this year using AI. Beyond this, we have a slate of digital product releases expected throughout 2024. I look forward to updating you on these developments over the coming months. We expect these margin-accretive initiatives and others to further bolster our ability to generate significant cash flow conversions, and we continue to view share repurchases as an attractive proposition.
We're in the privileged position to be able to make strategic growth investments in our business and buy back shares, all while maintaining a solid balance sheet with low leverage. Jagtar will provide more detail on our 2024 guidance in a moment, but I'd like to share a few high-level takeaways as we look ahead. First, WEX is incredibly resilient to economic conditions and is well-positioned for continued strong revenue growth. You will note in our guidance that we have made assumptions that include continued headwinds such as slower-than-normal U.S.
GDP growth and further depressed fuel prices. Despite these headwinds, we expect 2024 revenue growth in the 6% to 8% range, including a 2% headwind for lower fuel prices. All segments of the business will benefit from the full year impact of our sales activity in 2023. Within our mobility segment, we expect continued strong sales momentum, benefit from pricing actions, stabilization in the portfolio from the credit policy changes made a year ago, and the benefit of a full year of Payzer growth.
Within our benefits segment, we expect continued sales through our distribution channels, we expect continued growth in custodial assets and our organic customer growth and the Ascensus acquisition. Last but certainly not least, we expect strong growth within our corporate payments segment, built on continued strength in our embedded payments solution, inclusive of both share of wallet capture in our travel and partner businesses, as well as our investments in scaling our direct sales force becoming more meaningful to the segment. Second, we continue to be focused on delivering accretive EPS. This includes the high marginal contribution of incremental revenue to our businesses, our reengineering efforts that are delivering efficiencies across our enterprise, and pricing optimization work that yields strong drop-through to our bottom line.
Finally, our strong adjusted free cash flow underpins our ability to drive shareholder value. It enables us to invest in our market-leading products and solutions, as well as invest in our share repurchase program and our disciplined M&A program, all while maintaining a healthy balance sheet. As I look across our business, I am confident in WEX's future, our momentum in the marketplace, and our continued ability to deliver our long-term aspirations. With that, I'll turn it over to Jagtar to walk through this quarter's financial performance in more detail.
Jagtar.
Jagtar Narula -- Chief Financial Officer
Thank you, Melissa, and good morning, everyone. As you just heard, we again delivered strong financial results this quarter while continuing to make progress on our strategic objectives. The financial results in 2023 demonstrated the resiliency of the business in the face of a number of economic headwinds. Let's start with the quarter results.
Total revenue came in at $663.3 million, a 7.2% increase over Q4 2022, with more than 80% of revenue for the quarter recurring in nature. This exceeded the midpoint of our guidance by $8 million. Half of this outperformance was due to the contribution of Payzer, which closed on November 1st and was not included in our guidance, while the other half was a variety of small beneficial items. In total, adjusted operating income margin for the company was 39.6%, which is up from 38.5% last year.
High incremental margins on corporate payments volume and interest earned on custodial cash balances, as well as significantly improved credit and fraud losses, were the primary drivers of the margin increase. From an earnings perspective, on a GAAP basis, we had net income attributable to shareholders of $84.9 million or $1.98 per diluted share in Q4. Non-GAAP adjusted net income was $163.9 million or $3.82 per diluted share, and this represents an 11% increase over the prior year. I would like to take a moment to reflect on these results in the context of the overall macroeconomic environment.
Fuel prices were down 13% year over year in Q4, while the federal funds rate was up 100 basis points from the end of Q4 2022 to the end of Q4 2023. Our cost of financing and operating interest was up almost $35 million year over year. Yet, we grew revenue and earnings significantly, which reflects the reduced impact of fuel prices and interest rate volatility on our overall results and demonstrates the resiliency we have talked about repeatedly. Now, let's move to segment results, starting with mobility.
Mobility revenue for the quarter was $350.1 million, a 5% decrease compared to the prior year. The domestic fuel price in Q4 was $3.76, versus $4.34 in Q4 2022. This decline in fuel prices reduced segment revenue by approximately $24.9 million. In addition, mobility revenue growth was impacted by lower late fees, which I will discuss in a moment.
These lower late fees reflect the changes we made to credit policies that have dramatically improved credit losses and financially outweigh the impact of lower late fee revenue. The net interchange rate in mobility was 1.26%, which is up 15 basis points from the prior year. The lower fuel prices compared to last year, contractual increases due to higher interest rates, and renegotiated contracts with some of our merchants led to the increase in the net rate. The increase in the net interchange rate, combined with growing volumes over the past several years, also means the sensitivity to changes in fuel prices is increasing and now stands at $20 million of revenue impact and a $0.30 EPS impact for an annualized $0.10 change in fuel prices.
It is important to note that despite the higher gross EPS sensitivity to fuel, which reflects the growth and success of our mobility business, our overall earnings sensitivity to fuel price is lower than in the past as nonfuel-related revenue is an increasing portion of our overall earnings mix. As you see on our metrics, while the net late fee rate increased versus Q3, it was below the prior-year result. Overall, finance fee revenue was down 20% due to lower fuel prices and 28% decline in the number of late fee instances. Much of this decline is from a new portfolio that transitioned to us last year, which had higher late fee instances during the transition period, while the remainder we attribute to the stricter credit policies I mentioned earlier.
Again, emphasizing that the improvement in credit losses far outweighs this lost late fee revenue. The segment adjusted operating income margin for the quarter was down 2.1% compared to last year at 43%. Lower fuel prices and higher interest rates hurt operating margins, although this was partially offset by significantly lower credit loss rates. In addition, the acquisition of Payzer, which contributed $4.3 million in revenue with essentially zero adjusted operating income, decreased the segment margin by 60 basis points.
Turning now to corporate payments. Total segment revenue for the quarter increased 22% from the prior year to $135 million. Purchase volume issued by WEX was $22.8 billion, which is an increase of 33% versus prior year. The net interchange rate in this segment was up 10 basis points sequentially at 52 basis points, predominantly due to the recognition of network incentives based on full year performance.
Breaking the segment down further, travel-related customer volume was $16.2 billion and grew 40% compared to last year. Revenue from travel-related customers was up 39% versus last year. This reflects continued strength in consumer travel demand in the U.S. and Europe, as well as growing adoption of virtual cards in travel.
We believe that there is more room for growth as our OTA customers continue to emphasize the merchant model and we expand the types of payments that we are able to support. Nontravel-related customer purchase volume grew 21% versus last year, and revenue was up 5%. Volume growth was led by continuing strength in the partner channel. But importantly, approximately half the revenue growth came from our direct channel.
Our direct business is an important channel that we have invested in over the last year, and we are starting to see the positive results of this effort. The segment adjusted operating income margin was up 10.5% over the last year to 58.4%. There has been significant improvement in these margins during the year as volume accelerated. In fact, this is the second quarter in a row where more than 100% of the year-over-year revenue increase flowed through to adjusted operating income margin.
Finally, let's take a look at the benefits segment. We continue to drive strong growth in Q4 with revenue of $178.2 million. This represents an increase of $37.5 million or 27% over the prior year. Approximately half the revenue growth is due to contributions from custodial assets; and the remainder is from the Ascensus acquisition, increases in the account base, and purchase volume growth.
SaaS account growth was 7% in Q4 versus the prior year. Benefits segment purchase volume increased 10%, leading to a 5% increase in payment processing revenue. Custodial cash assets, including those on and off balance sheet, were $3.9 billion, on average, in Q4, versus $3.5 billion last year, representing an increase of 13%. Of the $3.9 billion total, approximately $1 billion was held at third-party banks, with the remainder held at WEX Bank.
We realized approximately $45.3 million in revenue in total from these deposits in Q4, versus $25.6 million last year. Although market interest rates declined during Q4, the blended yield of 4.6% was consistent with Q3. Compared to last year, the higher yield on those assets contributed $11.1 million in revenue, while the increase in balances contributed $8.6 million. In the first full quarter of ownership, Ascensus contributed $10.7 million of revenue, which was in line with our expectations for the quarter.
The integration process is going well. Recall that Ascensus was a cluster prior to our acquisition, so all accounts were already on our technology platform. And we are working through the remainder of the integration plan during 2024. The benefits segment adjusted operating income margin was 33.2%, compared to 28.1% in 2022.
The high flow-through on the revenue from the invested HSA deposits is the primary driver of the increase in margin. Shifting gears now, I will provide an update on the balance sheet and our liquidity position. We remain in a healthy financial position and ended the quarter with $976 million in cash. We have $731 million of available borrowing capacity on the revolver and corporate cash of $172 million as defined under the company's credit agreement at quarter-end.
The total outstanding balance on our revolving line of credit and term loans was $2.9 billion. The leverage ratio, as defined in the credit agreement, stands at 2.5 times, which is at the bottom end of our long-term target of 2.5 to 3.5 times. In December, we exited our interest rate hedge positions, leading to an immediate cash benefit of $50 million. As discussed in prior calls, the companywide net exposure to changes in interest rates has declined as we've grown the custodial cash assets in our benefits segment.
As a result, we determined that these hedges were unnecessary and we could exit them at favorable terms. Exiting the hedges accelerated the cash benefit we expected to see from the hedges to upfront rather than over time, which we intend to return to shareholders through share repurchases, and we have already repurchased $35 million to date through last week in 2024. As a result, we will see an increase in interest costs in 2024, especially in Q1 when rates are expected to be highest and with the elimination of the hedges that were already set to expire midyear. I want to emphasize, this reflects our belief in the time value of money benefit of receiving the cash earlier than we would have otherwise and returning this cash sooner to our shareholders.
Going forward, we intend to continue to evaluate our overall interest rate exposures annually and make adjustments to our hedging strategy, as necessary. During January, we successfully repriced $1.4 billion of term loans, reducing the spread over SOFR by 25 basis points and removed the credit spread adjustment. This will lead to interest savings of more than $5 million in 2024 on this branch of debt. There were no other changes to the loan agreement.
Next, I would like to turn to cash flow. WEX generates a significant amount of cash. Using our definition, adjusted free cash flow is $517 million for 2023. This compares to our adjusted net income of $646 million.
A reminder, as I have discussed previously, that rapid fuel price declines at the end of 2022 increased adjusted free cash flow by about $150 million to $175 million that year, which reversed during 2023. Taking this into account, adjusted free cash flow for 2023 was slightly less than adjusted net income, which is what we would normally expect. We are committed to driving strong cash generation and deploying it by both repurchasing our own shares and investing in our business, with an overall goal of maintaining strong long-term growth rates. For the year, we repurchased 1.7 million shares at a total cost of approximately $295 million, including approximately $150 million in the fourth quarter.
As a reminder, we also extinguished that $310 million convertible debt in Q3, which further reduced fully diluted share count by 1.55 million in Q4 compared to the prior year. Going forward, we expect to continue to allocate a portion of adjusted free cash flow to repurchase shares. Finally, let's move to 2024 revenue and earnings guidance for the fourth -- for the first quarter and the full year, starting with the first quarter. We expect to report revenue in the range of $650 million to $660 million.
We expect adjusted net income EPS to be between $3.40 and $3.50 per diluted share. For the full year, we expect to report revenue in the range of $2.7 billion to $2.74 billion. We expect adjusted net income EPS to be between $15.90 and $16.40 per diluted share. Let me spend a couple of minutes going through some of the larger assumptions in our guidance.
First, a couple of high-level macro assumptions. We are basing our guidance on U.S. GDP growth of around 1.5% for the year, which we have taken into account in our growth expectations. We're also expecting interest rates to decline in line with the market, which implies five quarter-point rate cuts during the year.
We have not included any future M&A activity or share repurchases except as we have already announced them. Mobility revenue growth, excluding the change in fuel prices, is expected to be at the high end of our long-term target, which is 4% to 8%, including approximately 2% for the contribution from Payzer. Fuel prices are expected to be lower in 2024 than in 2023, which is a headwind to revenue and earnings that is embedded in our guidance. We're assuming an average fuel price of $3.50 in the first quarter and $3.55 for the year, which compares to $3.86 for Q1 2023 and $3.82 for the full year 2023.
The fuel price decline is expected to reduce revenue and earnings per share by approximately $18 million and $0.27 per share in Q1 and $54 million and $0.81 per share for the full year compared to 2023 using the new sensitivity that I mentioned earlier. Again, this fuel price impact is already embedded in our guidance. Melissa mentioned some of our growth drivers earlier, which I will reiterate, including strong continuing sales engine, pricing optimization, full year benefit impact of Payzer, and stabilization in the portfolio from the credit policy changes made a year ago, which will also reduce the revenue drag from lower late fees that we saw in 2023. The corporate payments segment is expected to grow high single digits.
Similar to 2023 results, we expect the net interchange rate to come down slightly, mainly due to customer mix. We see significant demand for travel and expect to improve nontravel revenue growth in 2024. Finally, the benefits segment is expected to grow 10% to 15%. We have completed the open enrollment season, giving us confidence in the continued growth of this business.
Anticipated growth in custodial assets and tailwinds from organic growth in the Ascensus acquisition are expected to more than offset the loss of an individual Medicare Advantage customer. We are on track to remove $100 million of operating costs on a run rate basis by the end of 2024, as we previously outlined. We expect adjusted operating income margins to trend up through the year as we get the benefit of these cost savings measures and the impact of pricing initiatives that -- and scale that Melissa spoke about earlier. As I mentioned earlier, our decision to exit the swaps pulled cash forward, but also results in higher interest expense in 2024.
The impact is $0.19 per share in Q1 and $0.52 per share for the full year. Again, this is reflected in our guidance. As we have discussed, we aim to balance our fixed and floating rate assets and liabilities such that we would not expect material changes to overall adjusted earnings this year if there are changes in benchmark interest rates, although there could be impacts to individual segments. All of this leads to EPS growth in the range of 7% to 11%.
Isolating out our fuel price degradation and FX, we would expect adjusted EPS growth to be in the range of 13% to 17%. As I complete my prepared remarks, I would like to emphasize again how pleased we were with our results in Q4 and our outlook for 2024. We have great confidence in our ability to win new customers, expand with existing customers, and bring new products to market, all leading to continued long-term growth of the company. With that, operator, please open the line for questions.
Questions & Answers:
Operator
The floor is now open for your questions. [Operator instructions] Our first question comes from the line of Darrin Peller with Wolfe Research. Please go ahead.
Darrin Peller -- Wolfe Research -- Analyst
Thanks, guys. Maybe just touch a little more on the confidence in underlying just fundamentals given corporate payments yields fell a bit year over year and maybe just a little more on the benefits segment. I mean, when you think about guidance relative to recent trends, I'd love to hear a little more color on that first, if you don't mind.
Melissa Smith -- Chief Executive Officer
Sure. Good morning. I'm going to start, you know, with part of our confidence in next year's line of sight. When we ended 2023, we grew revenue 13%, excluding fuel prices and FX.
And if you look at the midpoint of our guidance for '24, it's 9% on the same basis. And going into that, if you go into -- I won't go into the segments now. Jagtar can if he wants to. But -- the across the business and one of the most important things for us is to continue the sales momentum that we had in 2023.
We'll get a benefit of the sales tail of what we sold this year, and we expect our sales professionals to continue to deliver in 2024. We also have pricing levers that we're going to continue to use, which we did in mobility in '23 and we'll continue, too, in '24. We'll get the benefit of the annualization on the changes we made from our credit policies, which will give us a lift from comparability standpoint, both on late fees and on attrition. And then we'll get a full year benefit of the acquisitions.
And then specifically U.S. corporate payments -- on the corporate payments side, we are expecting to see a lift on the nontravel part of our business. And you can see that has come through sequentially. Each quarter, we've come up a little bit over the last couple of quarters, and we're expecting that momentum to continue into 2024.
And that's coming from the pipeline that we have on our embedded payments product, as well as the success we've had with our direct sales force, which is becoming a more meaningful part of the business. And then we expect our travel business to become a little bit more muted in 20 -- from a growth perspective in 2024 compared to '23, which was, you know, bullish. We're coming off of 40% spend volume growth in the fourth quarter of 2023. And so, we're expecting as you go through the course of 2024 that that growth will moderate.
Darrin Peller -- Wolfe Research -- Analyst
OK. All right. That's great information, Melissa.
Jagtar Narula -- Chief Financial Officer
Yeah.
Darrin Peller -- Wolfe Research -- Analyst
Go ahead, Jagtar. I'm sorry.
Jagtar Narula -- Chief Financial Officer
No, I'm just going to -- I think Melissa hit all the key points. I was just going to reiterate. I think, Darrin, you were focused on benefits and corporate payments on the question. I would say, on benefits, right, in '23, we got a lot of benefit from interest rates.
You know, our -- of our 32% growth in '23, a little bit more than half of that came from rates. Not expecting that to repeat in '24. So, if you take that out and look at what's left, right, we've got a little bit of benefit from Ascensus. I mentioned the customer that's leaving.
But if you net those two out, what you'll find is that the underlying business continues to perform as it did in '23. We feel really good about that. And then on the corporate payments side, right, as Melissa mentioned, a little more growth in our nontravel business, mainly because, you know, we've got good visibility to the partners that we work with, as well as increasing confidence in our direct business. I pointed out in my prepared remarks that direct business was about half the growth in the nontravel part this quarter.
And so, we're really pleased with the investments we've made there and expect that to continue into 2024. So, we feel good about it.
Darrin Peller -- Wolfe Research -- Analyst
That -- thank you. I guess just my very quick follow-up would be on the corporate payments side, just to make sure we're clear. The medium-term targets -- I mean, there's obviously a lot of puts and takes on this year on the high single-digit corp payments growth. But when we think about the medium targets, they're still at 10% to 15%.
If you could just make sure -- you know, reiterate if you still have conviction in that? And then, you know, I guess with all these moving parts, it probably is clearer that why would we accelerate, but what would be your conviction in the driving forces of that back to 10% to 15% again?
Melissa Smith -- Chief Executive Officer
Yeah, I would describe those as long-term targets, the 10% to 15%. But, you know, as you're going into this year, you're moderating off from a really strong travel growth year. And so, that's -- you know, our expectation is that's going to decline in the course of the year. We'll see how that actually plays out, but that's the assumption we have in our guidance.
We also are seeing some really good ramp that's happening outside of travel. So, when you ask about confidence on our ability to hit our long-term growth targets, it's because of the ramp we're seeing outside of travel as well.
Darrin Peller -- Wolfe Research -- Analyst
OK. Great. Thanks, guys.

Our next question comes from the line of Sanjay Sakhrani with KBW. Please go ahead.
Sanjay Sakhrani -- Keefe, Bruyette and Woods -- Analyst
Thanks. Good morning. I guess, first question, just on the guide and sort of the macro forecast. It sounds like you guys are being pretty conservative with the GDP outlook.
I'm just curious if there's something you're seeing or is that just being intentionally conservative? Just trying to get a little bit color there. Thanks.
Jagtar Narula -- Chief Financial Officer
Yes, Sanjay. So, what we do during our planning process is we go out to a pretty large bank group, economists, you know, Moody's, S&P, you know, the Fed, other institutions that are publishing GDP forecasts. And so, when we average that up against the 20 institutions that we surveyed, we see about 1.5% is the average. And so, we use that in our planning process.
We're not trying to kind of make up what we think GDP is going to do. We really use it based upon what external parties are saying.
Sanjay Sakhrani -- Keefe, Bruyette and Woods -- Analyst
And I guess like what you've seen year to date with the weather and stuff, I mean, there's nothing that has led you to be more cautious or anything like that?
Jagtar Narula -- Chief Financial Officer
Yeah.
Melissa Smith -- Chief Executive Officer
No. From a trend perspective, there's nothing that we've seen. Same-store sales was down in the fourth quarter in the North American fleet, which was included in our numbers by 1.5%. Over-the-road is bend down, you know, throughout the course of the year for 2%.
And we just are assuming that the over-the-road market is stable in our numbers, as opposed to seeing, you know, a significant rebound. So, you know, there's a little bit -- I would say just a little bit of weakness that are coming through. Some of that, we think, is weather-related, and we'll know more as you see that play out in the first quarter. But anything that we've seen coming through January, you know, is [Inaudible]
Jagtar Narula -- Chief Financial Officer
[Inaudible] In line with expectations in January.
Melissa Smith -- Chief Executive Officer
Yeah.
Sanjay Sakhrani -- Keefe, Bruyette and Woods -- Analyst
Got it. And then, Melissa, you sort of talked about the benefit of -- the annualized benefit of the acquisitions. Maybe you could just talk a little bit about the contribution. And then, you know, Payzer, I know, wasn't really added to earnings, but maybe sort of what you guys expect in 2024? Thanks.
Melissa Smith -- Chief Executive Officer
Sure. Payzer, itself, we're expecting that to continue to grow at the rate it was. So, you know, plus-20% in our guidance in 2024. When you accumulate, you know, both the acquisitions, it's in our long-term target, that 2% to 3% of overall revenue growth, and it really is not material to earnings because Payzer came in -- we talked about the fact it was diluted last year, that -- and moving it to accretion during the course of the year.
So, it didn't really have much of an impact from an earnings perspective, but it's giving us a 2% to 3% lift in revenue.
Sanjay Sakhrani -- Keefe, Bruyette and Woods -- Analyst
Thank you.

Our next question comes from the line of Ramsey El-Assal with Barclays. Please go ahead.
Ramsey El-Assal -- Barclays -- Analyst
Hi. Thanks for taking my question this morning. I wanted to ask in the nontravel part of corporate payments, how much exposure you have to political ad spending in 2024? I recall that was a vertical that you were exposed to, I believe. And I'm just curious how much you think that's going to benefit you this year given it wasn't really in numbers last year as there wasn't a lot of political spending?
Melissa Smith -- Chief Executive Officer
That's actually really good memory. It was part of our model many years ago. It is actually not part of our model now, and so we really don't expect or not planning to have any meaningful impact based on the election.
Ramsey El-Assal -- Barclays -- Analyst
OK. And then I also wanted to ask about the strong sales momentum in mobility and just ask you to kind of break that down a little bit for us in terms of what's driving that. It seems like you're having some success in the marketplaces. Is that sales investment, incentive structures? Is it other factors that might be, you know, helping you to convert some customers out there in the marketplace?
Melissa Smith -- Chief Executive Officer
Yeah, it's been a long legacy of ours to deliver on a sales perspective in our -- across the business. But in mobility, we've had a multichannel approach where we're pulling in business for our partners, with which there's, you know, over 20 branded relationships with names that you would recognize. And then on top of that, under direct channels. What I would say, for the course of the last couple of years, there's been a significant conversion where that business is coming from, where much more is coming through the business digitally.
And so, a lot of the work and change in work has come from increasing our marketing effort, changing the way that the business comes through. So, it's coming through more fluidly through our digital channels. And so, we've seen that, you know, the benefit of that was the fact that we are actually bringing in more with less sales costs associated with that. And so, when I talk about the success of that, I feel like we've done a great job of pivoting and marketing in a different way into that part of the business.
And we changed our credit practices in the course of the last year, and so that really required us to reboot applications volume activity in the course of the year. And you can see the benefit of that has come through, you know, really every quarter. The approved applications that are coming from some of those smaller accounts are getting -- have grown. The size of the customers that are coming in are larger than they were a year ago, and therefore, we believe more profitable.
And so, we -- you know, I feel good about not just the numbers that we're bringing from the sales perspective, but the quality of what we're bringing in.
Ramsey El-Assal -- Barclays -- Analyst
Terrific. Thank you.

Our next question comes from the line of Andrew Jeffrey with Truist Securities. Please go ahead.
Andrew Jeffrey -- Truist Securities -- Analyst
Hi. Good morning, Melissa and Jagtar. I appreciate you taking the questions. Melissa, I'm curious about your comments about V card attach in travel.
And I wonder if you could talk about different use cases. I know the merchant model is one of the drivers, but are there other use cases to which you're referring that's driving attach? And then I wonder if you can expand a little bit in the same vein just in incorporate, you know, the -- you saw, you know, good volume growth and a little bit slower revenue growth over this quarter, although better than 3Q. And just sort of the dynamics of the V card acceptance and attach in that segment would be really helpful.
Melissa Smith -- Chief Executive Officer
Yeah. I know, last point, better than 2Q and 3Q. And likely, you can look sequentially, it's improved each quarter. Going back to the travel question, there's two primary drivers of the volume growth that we're seeing within travel that we were trying to highlight.
One is the fact that we've been working with our partners to shift volume to us, and most of our partners or many of them use multiple providers. And so, we've been working with them to make sure that we're set up in a way that creates value to them to move volume to us. And then the second part of that is in migration that you're talking about, which is largely this migration to the merchant model where the virtual card transaction actually is in play. Otherwise, people are paying the hotel directly, and we have benefited to both of those things, and you can see that coming through the 40% increase in travel spend we saw in the fourth quarter.
Jagtar Narula -- Chief Financial Officer
Then on the nontravel side, I would say, you know, as I mentioned earlier, you know, we saw really good results out of our direct investments. So, we did get good volume growth overall. A lot of that volume growth was in the partner channel, and that's just our partners performing well. But we had started making investments in the direct business, you know, late '22, accelerating into '23.
And so, you know, we expected to start to see the impact of that as we got through '23. And so, in the fourth quarter, we did -- you know, what we expected was start to see impact, and, you know, the rate is a little higher or a bit higher on the direct channel. So, that drove, you know, like I said, half the revenue benefit in the fourth quarter in the nontravel side. So, it's an area that we continue to invest in, we continue to watch, and we continue to be excited about.
Andrew Jeffrey -- Truist Securities -- Analyst

Our next question comes from the line of Dave Koning with Baird. Please go ahead.
Dave Koning -- Robert W. Baird and Company -- Analyst
Yeah. Hey, guys. And, yeah, good job. On the mobility segment guidance, the high end of the range, I guess, two questions.
First of all, how do you kind of see that through the year? I assume Q1 starts a little lower. And then secondly, gallons and transactions have been pretty flat in the last few quarters. Is that what's going to accelerate or is it something else around yield or account fees or finance revenue?
Jagtar Narula -- Chief Financial Officer
Yeah. So, let me -- first, your question about how that goes through the year. So, that -- you're absolutely right. We expect that to accelerate over the course of the year.
I'd say there's a few things driving the mobility segment. The first is the acquisition of Payzer. And I think Melissa mentioned this earlier. That adds about 2 points to the growth, right? If you back off the Payzer, there's a couple of things that we saw in '23 that we think we'll start to lap in '24.
So, the first thing we saw was lower late fees. That was, you know, roughly a 3%-ish drag on '23 revenue in the mobility segment. And that was, you know, the result of the new -- you know, the tighter credit that we had in 2023. Obviously, as I said in my prepared remarks, we think that was a good decision because the credit benefit outweighed the drag on late fees.
But as we get through '24, you know, we're not further tightening credit policy, so we'll start to lap that, and that won't be a drag. That also -- same thing also impacted gallons in 2023. Because we were tightening credit for certain customers, combined with, you know, weakness in the OTR segment, we saw some low gallon volume growth in 2023. Again, that's something we will start to lap those items in '24, hence our assumption of acceleration in '24 on both gallons and revenue.
Dave Koning -- Robert W. Baird and Company -- Analyst
Gotcha. Yeah, that was very helpful. And then secondly, it looks like there's no buybacks in the guidance just based on how you kind of guided Q1 and then full year being higher. What's the plan for use of cash this year? I mean, is it just to pay down debt given the higher rates now without the swaps?
Melissa Smith -- Chief Executive Officer
So, our intention is to use the cash both for acquisitions and for share buyback. And obviously, like we've been buying back stock. We bought back 1.7 million shares last year. And so, we have a -- you know, like a strong emphasis that we believe that our stock is still at a good value, and we'll continue to place emphasis there.
That being said, we will also, at the same time, look at pipelines for M&A transactions and evaluate that as another use of capital.
Dave Koning -- Robert W. Baird and Company -- Analyst
Great. Well, thanks. It's great to see it's not in guidance, it's kind of an upside driver. So, thanks for all that.
Melissa Smith -- Chief Executive Officer
Yes. Thank you.

Our next question comes from a line of Trevor Williams with Jefferies. Please go ahead.
Trevor Williams -- Jefferies -- Analyst
Great. Thanks. Good morning. I wanted to ask on benefits.
Melissa, maybe if you could revisit the longer-term growth algorithm in the 15% to 20% targets you guys had laid out earlier in 2023. And account growth has slowed in the last couple of quarters. I'm curious if you think high single-digit account growth is kind of the right normalized level that we should be thinking about going forward. And just if that's the case, how we bridge from that to the 15%-plus longer-term target? Thanks.
Melissa Smith -- Chief Executive Officer
Sure. If you look at Devenir's last report, they've got long-term HSA growth at 10%. So, still in the double digits. I think that those -- there are also cycles for that.
And then what we found going through this most recent open enrollment season is we had more nondecisions than we did the year before, which I would say was like a really strong sales cycle. And so, I think they're going to have anomalies within -- in each of the sales cycles. But over the long term, we do feel good about our ability to grow accounts. And then on top of that, what we're seeing now which we think will continue is that the custodial asset base will outpace the growth of the accounts, and that, you know, is a meaningful shift.
You know, as we've added that capability, the revenue per account, you know, has gone up, you know, pretty significantly. And so, there's, you know, an ability to create a new source of revenue that is a multiplier effect to the base of our portfolio. And then on top of that, we are continuing to cross-sell into that customer base the products that we've added, which are cover product or benefits restoration product, and most recently, the Ascensus capability. And so, when you aggregate all those pieces and then the expectation that healthcare costs are going to go up, and so the spend balances are going to increase, meaning the actual purchase volume will also be higher than the accounts.
Those were what drove our expectation of the long-term growth rates of this segment, which is something we'll keep talking about throughout the course of the year. You know, obviously, we're guiding below that in 2024 based on what we're seeing right now. We do feel very good. Our growth rates, though, you know, competitively that we are winning, you know, our fair share in the marketplace.
Trevor Williams -- Jefferies -- Analyst
That's helpful. Thanks. And for Jagtar, the payment processing rate in fuel for the year, that was up about 14 basis points, and you've referenced the last couple of quarters the benefit that you've gotten from the escalators tied to interest rates. Could you give us a sense just for how much of a tailwind the interest rate escalators were for the year? And with what you're expecting in terms of interest rates for 2024, just how much of that tailwind you would expect to reverse this year? Thanks.
Jagtar Narula -- Chief Financial Officer
Yeah. So, I would say the increase in the interchange rate in mobility was a mix between the tailwind of interest rates and also price negotiations we've had with merchant vendors where we've been able to improve price, and Melissa talked about pricing optimization earlier. So, it's a combination of the two. We expect next year, I mentioned the, you know, assumptions around five quarter-point rate reduction.
So, we expect that to be a slight drag on mobility revenue next year. You know, the way I think about it is 100-basis-point movement in rates on an annualized basis is about a $15 million impact on mobility revenue. So, that's the way I would model it.
Trevor Williams -- Jefferies -- Analyst
OK. Perfect. Thank you.

Our next question comes from the line of James Faucette with Morgan Stanley. Please go ahead.
James Faucette -- Morgan Stanley -- Analyst
Great. Thank you so much. Just a couple of follow-up questions for me. First, within mobility and the fleet business, can you talk about what you're seeing on a same-store basis and what are the drivers there? And can you give us any color on how -- what bearings you might be seeing across customer sets?
Melissa Smith -- Chief Executive Officer
In the fourth quarter numbers, we saw a negative 1.5% same-store sales in North American fleet and a negative 2% in over-the-road on same-store sales. You know, I said this earlier, but one of the things that we're curious about is whether weather had an impact on that. So, we'll see how that plays out in the course of this year because it was pretty broad brush. You know, it wasn't -- it was -- you know, if you look it across the various FICs, it was pretty much the same across every category, which is unusual.
And so, from our perspective, we think that was probably more weather-related. On the over-the-road side, we continue to hear from our customers, you know, that same -- you know, things have stabilized. They're coming off, you know, better comps. But we're not and they're not anticipating, you know, to seeing a big rebound anytime soon, and that's what we factored into our guidance, just this idea of stability.
James Faucette -- Morgan Stanley -- Analyst
Yeah. I got it. It makes sense. And thanks for that.
And then just -- like I know it's small and super early, but just since you launched the venture capital fund, I always think that that's kind of an interesting opportunity and exercise for WEX. Just any early views or learnings as you start to go down that and the types of potential investments that you're looking at?
Melissa Smith -- Chief Executive Officer
For us, it's to reinforce the idea that it was the right path because you've got a lot of early stage companies that are out there, many of them are pre-revenue, and it's given us an ability to learn in that marketplace without putting a lot of capital into it. And so far, I would say what we've -- we have made just a few investments. The companies that we've invested in are still out there in the marketplace, you know, proving out their value propositions. They all have interesting ones that are solving, you know, very specific niches in the marketplace.
And what we're able to do is then expose that to our customers and get a sense of what's going to get traction, what isn't. And so, you know, our objective is to have a open network where we're exposing through APIs many different types of functionality. Some of which, we'll own. Some of which, we're partnering with others on.
And these investments allow us an avenue to do that.
James Faucette -- Morgan Stanley -- Analyst
Great. Thanks for that, Melissa.

Our final question comes from the line of Cris Kennedy with William Blair. Please go ahead.
Cris Kennedy -- William Blair and Company -- Analyst
Good morning. Thanks for squeezing me in. Just a quick one on pricing, it's been mentioned a few times this morning, but can you talk about kind of what the impact was last year and some of the levers that you have going into 2024? Thank you.
Melissa Smith -- Chief Executive Officer
Yeah. The place where we're talking about pricing just really specific is in our mobility segment. It's the place that we continue to experiment within that customer segment our different ways of packaging and pricing to those customers. And also, you've seen the benefit of renegotiation of merchant rates.
And so, as we've gone into contract renewals with our merchants, we've been able to, on average, negotiate up on rates. And as Jagtar said, we've also got the benefit of interest rate escalators that were in there as well. And so, when we talk about pricing, it's this idea that we think that we'll continue to get benefits on the merchant rates. We also will continue to experiment with different ways of pricing into our existing customer base.
And we'll get a lift of that through the course of the year.
Jagtar Narula -- Chief Financial Officer
Yeah. I would add -- so I'm hesitant to give out a specific dollar amount related to pricing impact, but what I would say from a dollars perspective, we expect a similar impact in '24 that we saw in '23 from pricing, and most -- a lot of which is -- almost all of which is already baked in because we've completed those negotiations and price changes.
Cris Kennedy -- William Blair and Company -- Analyst
Great. Thanks for taking the question.
