Reciepts for everything, EXCEPT Meals. Meals are a $35 max per day. Your on your own to expense what you spend up to $35. Hotel, Airline and Car all have to be on your corperate card.

On another note, corperate cards came into favor when the IRS said that you DON'T need reciepts for charges made on a company credit card. For cash based reciepts i believe it is $75.
