I don't know if they are going to have agreements with all three of them but this is the sweet spot of the market. Their partnership with AmEx is just getting started too. The first stage would not win many new clients because Concur already has most of the large clients that would be willing to move (many have systems that they are not willing to change since they cost so much to get set up and are licenced or home made). The mid and small markets is where growth is at and is just getting started with AmEx and Concur. That along with a new potential partnerships is going to really take off. We should first see signs of this after the anouncement by the job postings that will increase. The anouncement should come in January according to the earnings expectation from what was said in the earnings call. Concur stock will start to take off from this anouncement as many others jump on for the ride. Good Luck!
SAP will step on Concur like a pesky mesquito. SAP has the time and money to destroy Concur. Many large customers are fed up with Concur and their inability to support customizations. I look for Concur to sell or die. Don't forget the Concur management have been known to exaggerate.
The anouncment could be an expanded agreement with ADP. ADP does have over 585,000 customers and the current agreement is only for large customers with contracts written by ADP and not self service deals like they are going to start. Either way growth will be coming.
