Free Purchase Order Generator
A purchase order (PO) is the buyer's official order document: it tells the supplier exactly what to deliver, at agreed prices, by when. Once the supplier accepts it, the PO is a binding contract — and the seller's invoice must reference the PO number to get paid promptly.
Quick answer: A purchase order is the buyer's official order: itemized goods or services, agreed prices, delivery date and a PO number the supplier references on the invoice. Accepted, it becomes a binding contract.

Frequently Asked Questions
What is the difference between a PO and an invoice?
The PO is issued by the buyer before the goods or work are supplied; the invoice is issued by the seller afterwards to request payment. They share line items and totals, in opposite directions.
Is a purchase order legally binding?
Once the supplier accepts it, yes — a PO is a contract for the listed goods at the listed prices. That is why buyers should only issue POs for spend they have approved.
Why do suppliers ask for a PO number?
Corporate finance teams match invoices to POs before paying (three-way matching: PO, delivery, invoice). An invoice without a PO reference often stalls in approval for weeks.
