I have a love/hate relationship with Concur. I actually love the app: I just take photos of the receipts directly from the app...far simpler than our old SAP process which basically required you to get all of the receipts from a trip into a single large PDF to submit with the report. People here all had slightly different ways of doing it, usually involving spending time taping receipts together, going to the copy room, sending yourself a scan, etc. (If there are more elegant ways of doing this within SAP, I never figured them out.) So Concur is a big leap forward in terms of preparing and submitting a report.

The hate part is the Concur audit step. Yes, we use that - offshore contractors from Concur do 1 round of audit before it actually gets back to the real approver. Those guys consistently choke on hotel receipts that have multiple expenses, hotel room rates that change mid-stay, and (oddly) my own airport's parking receipts. I suspect there's a bot trying to scan for things first and then humans who look as well, but the rejected reports are usually because somebody didn't look at something in the right place. That part is frustrating.

Once I get through the Concur audit, my own approver finishes it within a day or so...
