How should I write a receipt if I can't receive the money?

How to write a receipt in advance without receiving money?

1. If you don't receive the money, you need to write a receipt in advance, and you need to directly indicate that the money has not arrived in the account in a prominent position. Other formats are the same as ordinary receipts, or you need to write IOUs.

But when you don't receive the payment, try not to give the other party a receipt first, which will be risky.

3. It is ok to issue a receipt for reimbursement first, but there must be a relationship of mutual trust between the two units, otherwise it will be financially and legally impossible.
