I actually love Concur. We just moved to it earlier this year and it more or less auto-approves in-policy expenses on the spot and seems to have smart logic to auto-approve "in-policy but requires receipt" purchases as well. The reimbursement time has substantially decreased and the process is so much easier than it used to be.

I agree hotel itemizations are a pain and sometimes require some funny math because of the way the tool is laid out (especially when there are different rates every night and then different local taxes based on those different rates) but on the whole it's been a huge improvement for us.

Ours is also directly layered into our travel portal so that makes things flow much more smoothly too because Concur serves as both the booking tool and the expense tool so that helps support the auto-approving.
