Is an itemized invoice/order sufficient for documentation? Or do I also need to keep the form of payment.
e.g. I put in an order for a list of items at a store; then I pay for that order at a cash register. The register receipt just shows the total I paid -- with no itemization. Do I need to keep both piece of paper for documentation.
How about payments I made to Contractor by check? I don't get the cancelled check back. How do I document that payment?
What documentation do I need for ordering online and pay by CC? Will the online invoice/order that shows payment sufficient? When I print out the Order right after the transaction, it doesn't show date of shipment. Do I need to print the same Order again after the items are shipped? And sometimes it doesn't show the shipped date at all.
TIA
