A purchase order (PO) is a document a buyer sends to a supplier to formally request goods or services. It specifies what is being ordered, in what quantity, at what price, and when and where it should be delivered. Using a PO protects both the buyer and the supplier — it is a legally binding agreement once accepted.

What every purchase order must include
- PO number: A unique reference number for tracking. Both you and the supplier should reference this number on all correspondence and invoices related to this order.
- Buyer details: Your company name, address, ABN, and contact person.
- Supplier details: The vendor's name, address, and contact person.
- Order date and delivery date: When the PO was issued and when the goods or services are needed.
- Itemised list: Description, quantity, unit price, and line total for each item.
- Subtotal, tax, and total: The complete cost breakdown.
- Delivery address: Where the goods should be shipped.
- Payment terms: When payment is due (e.g. Net 30 — payment within 30 days of delivery).
- Authorised signature: The person at your company approving the purchase.
Purchase order vs invoice — what is the difference?
- Purchase order: Created by the buyer and sent to the supplier before goods or services are delivered. It is the buyer's formal commitment to purchase.
- Invoice: Created by the supplier and sent to the buyer after goods or services are delivered. It is the supplier's request for payment.
In a typical purchasing workflow: Buyer sends PO → Supplier accepts PO → Supplier delivers goods → Supplier sends invoice referencing the PO number → Buyer pays invoice.
When should you use a purchase order?
- Ordering stock or inventory from a supplier.
- Engaging contractors or service providers for work above a certain value.
- Any purchase that needs approval before the supplier begins work.
- Government or corporate procurement — most organisations require a PO for any external purchase.
For very small or one-off purchases from familiar suppliers, a PO may be overkill. But for any recurring supplier relationship or significant purchase, a PO provides important protection for both parties.
Frequently asked questions
Is a purchase order legally binding?
Yes, once the supplier accepts a purchase order — either explicitly or by beginning fulfilment — it becomes a legally binding contract. The supplier is obligated to deliver the specified goods or services, and the buyer is obligated to pay at the agreed price.
Can I use a purchase order for services, not just goods?
Yes. POs work equally well for services — consulting, design, construction, maintenance. Specify the service description, scope, and rate in the line items, and include the delivery date as the date the service should be completed.
