They made some change back in July that prevented me from submitting any expense reports (the error message was something to the effect that I didn't have a balance to charge the submission against). I'm the only person in my company, so it couldn't have been the number of employees, unless the number of employees that can use it for free is zero.

Perhaps too many abandoned ship at that point and they reversed their decision. Too late for me, though; I'd already torn down the linkages to my bank and credit card accounts and unsubscribed from their email notifications. I know they need to make a buck, but I have other options that aren't that much more difficult and remain free.
