The coolest tool I have seen in weeks is NeatReceipts. This portable scanner not only captures all your receipts, accurately accounts for the amounts, and drops them into a usable/customizable spreadsheet, it also has a business card scanner. Did I mention - IT'S PORTABLE?
My boy has one and he takes it on all his road trips, tallies the expenses as he goes, throws the paper away and emails in the results. If you spend the amount of time I do trying to account for all the money you spend on the road then this would be worth the cost.
