Purchase Order Generator: The Complete Guide

Authorise supplier purchases formally. Everything you need to know — plus a free tool to do it instantly.

What is purchase order?

A purchase order (PO) is a formal commercial document from a buyer to a supplier, authorising a purchase. Once accepted by the supplier, it becomes a legally binding contract protecting both parties. POs enable proper spend control, inventory planning, and three-way matching (PO → delivery note → invoice) in accounts payable workflows.

How it works

Fill in your business (buyer) and supplier details, add line items with quantities and units (Box, Kg, Pcs, etc.), set the expected delivery date, add any special terms, and export a professional PO as PDF or Excel.

Why it matters

Verbal orders lead to disputes. A written PO protects you legally, enables proper budget approval workflows, and gives your supplier a clear, formal reference to fulfil.

Common mistakes

Not specifying delivery dates — always include an expected delivery date
Missing unit prices — all pricing should be agreed in the PO before goods ship
No payment terms — specify net days clearly

Best practices

Use sequential PO numbers and keep a PO register
Always get supplier acknowledgement/acceptance of the PO
Match the PO to the delivery note and supplier invoice before paying (three-way match)
