A purchase order (PO) is a document that a buyer issues to a seller to request goods or services. To create a purchase order, start by listing the buyer and seller details, including company names and addresses. Next, add the PO number and date for tracking purposes. Then, specify the items or services being purchased, including descriptions, quantities, unit prices, and total costs. Mention payment terms, delivery date, and shipping details to ensure clarity. Once completed, review the PO for accuracy before sending it to the supplier. The supplier will confirm the order, and upon delivery, the PO helps in verifying the received goods.
