Commit to a purchase in writing — itemised, numbered and on your letterhead — in about a minute.
A purchase order (PO) is a formal document a buyer sends a supplier committing to purchase specified goods or services at specified prices. Once the supplier accepts it, the PO typically forms a binding agreement — which is why growing businesses adopt POs as the moment of spend control: nothing is ordered until someone has put a number, a price and a signature on a page. The supplier later invoices against the PO number, and the buyer matches invoice to PO to delivery before paying — the classic three-way match.
Because verbal orders are where money leaks. A PO pins the agreed price before the supplier invoices, creates an audit trail for every commitment, prevents duplicate or unauthorized orders, and gives you grounds to reject an invoice that doesn't match. When a supplier's invoice arrives quoting your PO number, reconciliation takes seconds instead of an email thread.
If you're on the receiving end of POs, create your invoice here and put the customer's PO number in the reference field — it prints prominently, and the finance team on the other side will clear it faster. Your invoice generator shares clients, items and branding with this PO tool.
Like every tool on this site, the purchase order maker runs entirely in your browser. Clients, line items and history are stored on your device in IndexedDB — never uploaded, never seen by us, exportable as a single backup file, deletable any time. It also works completely offline once loaded, and the PDF never carries a watermark.
Generally yes once the supplier accepts it — it becomes a contract for the listed goods at the listed prices. Until acceptance it is an offer to buy.
The PO comes from the buyer committing to purchase; the invoice comes from the supplier requesting payment, usually citing the PO number. They are the two halves of the same transaction.
Yes — sequential PO numbers are the backbone of purchase control and three-way matching. This tool keeps a dedicated PO sequence per business profile.
Yes — use the ship-to block for the delivery address and the notes/terms blocks for dates, packaging or receiving instructions.
