A purchase order (PO) is a commercial document issued by a buyer to a vendor, authorizing a purchase. POs create a legal contract, help control spending, track inventory, manage budgets, and provide an audit trail for accounting.
A purchase order is created by the buyer before receiving goods/services to authorize the purchase. An invoice is created by the seller after delivery to request payment. The PO number should appear on the corresponding invoice.
Yes, once a vendor accepts a purchase order, it becomes a legally binding contract. The vendor agrees to provide the specified goods or services, and the buyer commits to paying the agreed amount upon proper delivery.
Include: PO number, issue date, vendor details, ship-to and bill-to addresses, item descriptions, quantities, unit prices, total amount, delivery date, payment terms, and authorized signature.
While not required, POs benefit businesses of any size by preventing unauthorized purchases, avoiding duplicate orders, tracking spending, simplifying receiving and accounting processes, and resolving disputes about what was ordered.
