I see that you have also identified the central value proposition of Concur.

It’s true though. I recently bought a $100 thing for work, and my manager found out I paid for it myself, so told me to expense it through concur.

“You pay me enough that I can afford not to deal with Concur or our expensing process.”

I've wasted more time (and thus salary cost) using Concur than any amount of money the company is 'saving' by making me USE Concur. An asinine, idiotic, cumbersome, SLOW inefficient and often _wrong_ process to book any travel with.
