Questions

Does StackProcure replace a punchout middleware?
For a vendor punching out to buyers, yes — StackProcure is the punchout server on your catalog, so you don't need a separate middleware layer between your store and your buyers.
Can StackProcure connect to the same procurement systems?
Yes — cXML 1.2 and OCI 5.0 cover Coupa, Ariba, Prendio, SAP SRM, Jaggaer, Oracle iSupplier and in-house systems.
What if I already use TradeCentric?
You can run StackProcure alongside it and migrate buyers over as you validate each connection — there's no big-bang cutover.
