Not really. If you just have a receipt/invoice and maybe a bank statement showing the payment that's about as much paper trail as an auditor would look at.

It's going to be pretty obvious to any auditor or even a lowly inventory clerk that something stinks when they can't find the bill of lading or waybill, purchase order, check in or even a received count for any supplies.  Shorting customers and carriers who lose things are some of the oldest tricks in commerce.
