I think my employer would have had a hard time with that. We have a high-tech expense account system and our corporate card charges are automatically entered into the expense account system. If it's a hotel folio you need to break out meal, phone, etc, charges, but most of the time you just assign a category to the charge, click to submit, and you're done. Fewer receipts required, too- I've never had to submit one for airfare. Makes life a lot easier.
