A purchase order (PO) is a formal document issued by a buyer to a seller, specifying the details of products or services to be purchased. It includes essential information such as item descriptions, quantities, prices, payment terms, and delivery schedules. A PO serves as a legally binding agreement that ensures transparency and accountability in business transactions. It helps organizations manage procurement efficiently, track expenses, and maintain accurate records. By streamlining purchasing processes, a purchase order minimizes errors, prevents unauthorized purchases, and enhances supplier relationships. Businesses rely on POs to ensure smooth operations and financial control over procurement activities.
