I've been using Concur for over a year now. Compared to other systems I've used it is VERY, VERY good. I do a lot of multi-currency reports and Concur automatically downloads and converts AMEX statements for me. Concur, because of its automatic link to my AMEX bill forces to me reconcile everything that comes in on my card. I really never have to worry about forgetting to expense something becuase it will be there in Concur staring me in the face every time I log on.

In addition, I find the payment reporting, itemization (for hotel expenses) and history features all very intuitive.

I'd give Concur an unqualified thumbs up!
