How to use this purchase order template
You are the buyer, so your business goes in the "Buyer" block. Enter the vendor you are ordering from, and the "Ship to" address if goods should be delivered somewhere other than your main address, such as a job site, warehouse, or a customer. List each item with the quantity and the price you agreed (usually from the vendor's quote), set the delivery date you need, and add your terms. Download the PO as Word or PDF and send it to the vendor; keep a copy to match against their invoice later.
What a purchase order is, and who issues it
A purchase order (PO) is a document the buyer sends to a supplier to order goods or services on stated terms. It says: we want these items, in these quantities, at these prices, delivered here by this date, and we will pay on these terms. When the supplier accepts it, by confirming in writing or simply by shipping, the PO becomes a binding contract.
That direction is the thing people most often get backwards. A quote comes from the seller; a PO comes from the buyer; an invoice comes from the seller again. The PO sits in the middle, converting the seller's offer into the buyer's commitment.
For a small business the PO does three practical jobs:
- It gives the supplier a clear, written order so nothing is lost in a phone call.
- It creates a record of what you committed to spend before the invoice arrives.
- It gives you a number that the supplier must quote on their invoice, which is what makes checking that invoice fast.
Purchase order vs. invoice
| Feature | Purchase order | Invoice |
|---|---|---|
| Issued by | Buyer | Seller |
| When | Before goods ship | After goods ship or services are delivered |
| Says | "We agree to buy this" | "You owe us this" |
| Legal effect | Offer, binding on acceptance | Demand for payment under the contract |
| References | Vendor's quote | The PO number |
The two documents should agree on items, quantities, and prices. When they do not, the difference is either an error or an unapproved change, and the PO is what lets you tell.
PO numbering
Every PO needs a unique number that is never reused. Beyond that, keep it simple:
- Sequential: PO-1001, PO-1002. Right for most small businesses.
- Year-prefixed: PO-2026-014. Makes year-end reconciliation easier.
- Department- or project-prefixed: PO-SITE7-003. Useful for contractors tracking spend per job.
Record every number issued in a log with the vendor, date, amount and status (open, received, invoiced, paid). The template starts at PO-1001; change the prefix in the form and it will be remembered for next time.
Three-way matching
Three-way matching is the control that makes purchase orders worth the effort. Before an invoice is paid, three documents are compared:
- The purchase order – what you ordered and at what price.
- The receiving report (packing slip, delivery note, or a signed confirmation that services were performed) – what actually arrived.
- The supplier's invoice – what you are being asked to pay.
If all three agree, pay the invoice. If they do not, hold it and find out why. Common mismatches and what they mean:
| Mismatch | Likely cause | Action |
|---|---|---|
| Invoice quantity > received quantity | Short shipment or billing error | Pay for what was received; request credit |
| Invoice price > PO price | Price increase not agreed, or wrong price list | Query before paying |
| Invoice items not on PO | Substitution, upsell, or wrong customer | Approve as a change or reject |
| No PO number on invoice | Order placed informally | Trace who ordered it; issue a retrospective PO if legitimate |
Even a two-person business benefits from a light version: staple the packing slip to the PO copy when goods arrive, and pay invoices only against that pair. It catches short shipments and double-billing that would otherwise be paid without anyone noticing.
Approval workflows for small teams
A PO system does not need software to work. What it needs is a rule about who can commit the business to spending money. A workable approach for a team of two to twenty:
- Under a set threshold (say $500), any team lead can raise and sign a PO within their budget.
- Above the threshold, the owner or a designated approver signs before it is sent.
- Above a second threshold (say $5,000), two quotes are required and attached to the PO.
- Nothing is ordered without a PO number, and suppliers are told that invoices without one will be returned.
Write the thresholds on one page, share it with the team and the suppliers, and review it once a year. Most overspending in small businesses is not fraud; it is three people each ordering the same thing because nobody knew who was responsible.
PO terms: delivery, payment, cancellation
The terms field prints under the totals. Cover the points that cause disputes:
- Delivery. Required date, address (use the "Ship to" block), who pays freight, and what happens if delivery is late. For goods, state the shipping terms (e.g. FOB destination) so it is clear who bears risk in transit.
- Payment. When you will pay (Net 30 from receipt of a correct invoice is standard), how, and that invoices must quote the PO number.
- Inspection and rejection. Goods are subject to inspection on receipt; non-conforming or damaged goods may be returned at the vendor's expense within a stated number of days.
- Cancellation. Whether you may cancel before shipment without charge, and whether the vendor may cancel. Custom or made-to-order goods usually carry a cancellation fee; agree it up front.
- Substitutions. Not permitted without written approval.
- Price. Prices on the PO are fixed unless agreed in writing; no charges not shown on the PO will be paid.
Two or three lines on each is enough. If your vendor's quote or terms conflict with your PO, whichever document is accepted last generally governs, so read their order confirmation before assuming your terms apply.
Worked example
A landscaping company orders paving materials for a job. Its PO-1027, dated September 24, 2026, requests delivery to the job site by October 8:
| Description | Qty | Unit price | Amount |
|---|---|---|---|
| Bluestone pavers, 24 × 24 in, per pallet | 6 | $485.00 | $2,910.00 |
| Polymeric sand, 50 lb bag | 20 | $32.50 | $650.00 |
| Delivery to site | 1 | $175.00 | $175.00 |
Subtotal $3,735.00. The vendor agreed a 5% trade discount ($186.75), bringing the taxable amount to $3,548.25. Sales tax at 7% adds $248.38 for an order total of $3,796.63. When the pallets arrive, the site foreman counts six pallets and twenty bags and signs the delivery note. When the invoice arrives quoting PO-1027 for $3,796.63, it matches all three documents and is paid on Net 30 terms. Had the invoice shown seven pallets, the foreman's count would have caught it.
When you need a PO system
This template is enough when you raise a few POs a month and keep a log in a spreadsheet. Consider dedicated purchasing software when:
- More than a handful of people can place orders and you need approvals routed automatically.
- You want to see committed spend (open POs) alongside actual spend, so that a budget is not blown by orders that have been placed but not yet invoiced.
- You receive dozens of invoices a month and manual three-way matching is falling behind.
- Suppliers need to acknowledge orders and update delivery dates in a portal rather than by email.
Open POs also matter at period end. Goods received but not yet invoiced are a liability that belongs on your balance sheet as accrued purchases; a PO log makes that figure a five-minute job rather than a guess.
