What document is typically used to authorize a one-time payment?

A cheque requisition form is specifically designed to authorize a one-time payment. This document serves as a formal request for the issuance of a cheque to pay for goods or services received. It contains details such as the amount, payee information, and the purpose of the payment, ensuring that all necessary approvals are captured before the payment is processed.

While an invoice is a request for payment from a supplier, it does not itself authorize the payment—it is a document that shows what is owed. A purchase order is a document sent from the buyer to the supplier to confirm the sale and specify the items, quantities, and agreed prices, but it is not typically used for one-off payments; it is more about initiating orders for ongoing or multiple transactions. A statement is a summary of transactions over a certain period and is used for record-keeping rather than authorizing payments.
