The official business definition of a Request for Purchase Order (RFPO) is a document that is used to initiate the purchase of goods or services from a vendor. It is a formal request from a buyer to a seller that includes all the necessary information for the seller to process the order. This includes the item description, quantity, price, delivery terms, payment terms, and any other relevant information. The RFPO is typically the first step in the purchase process and is used to ensure that the buyer and seller have a clear understanding of the terms of the transaction. It is important for both parties to have a clear understanding of the details of the purchase before any money is exchanged. The RFPO also serves as a legal document that can be used to protect both parties in the event of a dispute.
