A payment voucher verifies that the company and customer have made some transaction, and it can signify a payment receipt, an approved invoice or cash substitution. This document may also be used when a customer needs a refund for an item that has been returned.
When a person is preparing a payment voucher, there are several items that should be included. The vendor or payee ID and the invoice number should be included to identify the order and the buyer. There should also be a list of the order's items and materials received, as well as the dates the invoice was received and the payment was requested. Attachments are optional and generally don't include the invoice itself.
