Expense tracking software

I apologize if this is a FAQ; I did a search but didn't find any other posts. My boss would like to know if there is any software or sites that would allow his captian and crew to post their expenses, so that he can review, approve, and track them on a more timely basis. Something web based makes the most sense since the boat is in the Bahamas and we are in Connecticut. TIA for any suggestions.

I'll give it a try. Thank you.
