What is a purchase order?

A purchase order (PO) is a formal document a buyer sends to a supplier to request specific goods or services at an agreed price. Once the supplier accepts the PO, it becomes a legally binding contract. POs give both sides a clean paper trail, make procurement easier to audit, and prevent "I thought we agreed on..." disputes.

Purchase order vs invoice — who sends what?

DocumentWho sends it?When
Purchase orderBuyer → SupplierBefore work starts
InvoiceSupplier → BuyerAfter work completes

The invoice the supplier eventually sends should reference the PO number — that's how accounts payable matches the two documents. For more on invoice structure and payment terms, see how to create a professional invoice.

FAQ

Is a purchase order legally binding?

Once the supplier accepts it — yes. A PO is an offer; acceptance creates a contract. Both sides are then bound to the agreed terms, price, and delivery.

What's the difference between a PO and a proforma invoice?

A PO is sent by the buyer to request something. A proforma invoice is sent by the supplier to preview what will be billed. If you need the supplier-side document, use our proforma invoice generator instead.
