Free Purchase Order Generator

How to use this purchase order generator

1. Enter a PO number and the date you are issuing it. Keep purchase orders on their own series — PO-2026-0147, not a continuation of your invoice numbers. That number is about to become the reference every invoice, delivery note and payment against this order is matched on, so it has to be unambiguous a year from now.
2. Put yourself in the From block. This is the field people get backwards: on an invoice you are the seller, and on a purchase order you are the buyer. The supplier goes in the Supplier block on the right, and their name there is who you are committing to pay.
3. Itemise with a quantity and a unit price on every line. A purchase order that says "illustration work — $7,280" cannot be matched against anything, because there is no unit to compare a delivery against. Twelve at $335.00 can be checked when eleven arrive; a lump sum cannot.
4. Set the deliver-by date, which is not your payment date. The date field on an invoice says when money moves; on a purchase order it says when the work is due to land. Put your payment terms in the Terms field instead, and keep the two clocks separate.
5. Download the PDF and send it before the work starts, asking for the acknowledgement block to come back signed. A purchase order the supplier has accepted is the document that pins the scope; one sitting unsigned in an inbox is a wish.

Why the PO number decides whether an invoice gets paid

Every other document on this site is written by the person who wants to be paid. A purchase order is written by the person who is going to pay, which reverses everything about it: you are stating what you are willing to buy, at what price, by when, and you are the one taking on the commitment. For a freelancer that direction runs both ways, and both are worth getting right. When you subcontract — an illustrator, a developer, an editor, a print run — you are the buyer and this is your document. When you work for a company of any size, the purchase order is something they send you, and reading it properly before you start is the difference between a smooth invoice and a silent one.

The single most expensive thing to know about purchase orders is what happens when the number is missing. At most companies your invoice is not read by a person deciding whether to pay it. It is matched automatically against an open purchase order, and the PO number is the key that lookup runs on. An invoice arriving without one does not get rejected and does not get flagged to you — it goes into an exception queue where it waits for someone to have time to work out what it belongs to. You are not late, you are unmatched, and nobody is going to call. Freelancers routinely spend six weeks chasing a payment that was never refused; it was simply never matched. Get the PO number before you invoice, and put it where they expect it.

The match has three legs — the purchase order, a record that the work or goods were received, and the invoice — and all three have to agree before payment releases. Writing the purchase order is the easy leg. The one that actually breaks, and the one you control when you are the buyer, is the receiving record. If you accept twelve illustrations and never note anywhere that they arrived, your supplier's correct invoice will sit unpaid against your own correct purchase order, and the two of you will spend a fortnight looking for a problem that does not exist. A dated line in the notes of the PO, or a reply confirming receipt, is enough at freelance scale. The formality is worth nothing; the record is worth everything.

A purchase order the supplier has accepted binds harder than an estimate the client has approved, and the reason is the direction of the offer. An estimate is your proposal and the client is free to walk away from it. A purchase order is an offer to buy on stated terms, and once the supplier accepts it — signing the acknowledgement, or simply starting the work — there is an agreement with a quantity, a price and a date in it. That is why those three things belong on the page and not in the email thread above it. If you want twelve illustrations and you write twelve, you owe twelve and you owe $4,020.00. If you leave the quantity open because it felt friendlier, you have a price with no boundary attached to it.

If you are on the receiving end, read the purchase order before you start rather than when you invoice. Check that the total matches the estimate you sent, that the description covers the work you actually agreed and not a shortened version of it, that the delivery date is one you can meet, and that the number is legible enough to copy onto an invoice. A purchase order for less than you quoted is not a typo you should absorb quietly — it is the amount you will be paid, because it is what their system will match against. Raising it on day one is a two-minute conversation. Raising it after delivery is a dispute.

Example

A freelance art director has won a mobile game art pack and is subcontracting the drawing to an illustrator. She is the buyer here, so she issues the purchase order — fixing the count, the unit prices and the delivery date before anyone opens a canvas, and creating the number the illustrator will quote back on her invoice.

Purchase order total: $7,280.00 — every invoice against it must quote PO-2026-0147.

The total is $4,020.00 plus $2,600.00 plus $660.00. What makes this a purchase order rather than a number in an email is that each line carries a count and a unit price. When nine characters arrive instead of twelve, there is a $335.00 unit to multiply and the shortfall is $1,005.00 — a fact rather than an argument. A single line reading "game art pack — $7,280.00" would make a partial delivery unresolvable without reopening the whole negotiation.

The revision round is a priced line, not a courtesy. One round across all seventeen assets for $660.00 tells the illustrator exactly how much redrawing is inside the price, and tells the art director what the second round costs if the client asks for one. Revisions are the most common place a subcontract quietly loses its margin, precisely because they are usually agreed verbally as "a few tweaks" and then discovered to be unbounded.

Two dates, two meanings. Deliver by 2026-10-05 is 21 days out and is about artwork landing. Net 30 from receipt of a matching invoice is about money leaving, and its clock does not start until both the work and the invoice have arrived. Collapsing them into one field is how a supplier ends up believing they will be paid on the fifth of October. Written this way, the illustrator can see the delivery date is hers and the payment date is the art director's, and neither has to guess.

PO-2026-0147 is doing more work than any other character on the page. An invoice headed "Illustration work, September" is a document a human has to interpret; an invoice headed "PO-2026-0147" is a row a system can find. The acknowledgement wording in the generated PDF asks the supplier to quote it on every invoice and delivery note for exactly this reason — and if the art director is in turn billing her own client under their purchase order, she now has two numbers to keep straight, hers going out and theirs coming in.

One obligation runs the other way. Having issued the order, the art director owes a record that the work arrived — a dated note against PO-2026-0147 confirming twelve characters and five backgrounds received — and, if the illustrator is US-based, a W-9 collected before the first payment rather than chased the following January. Neither takes long on the day. Both are miserable to reconstruct after the fact.

Limits and things to watch for

• This produces a single-page purchase order. Long specifications should stay in a separate scope document that the PO refers to by name, with the summary lines kept on the order itself.
• Nothing is saved. The tool keeps no data, so closing the tab discards your work. Download the PDF before you navigate away, and file it somewhere you can find it when the invoice arrives.
• It does not number your orders, track which ones are still open, or tell you how much you have committed but not yet been billed for. That open-commitment figure is the real point of purchase orders in a business, and keeping it is your job here — a spreadsheet is enough at freelance volume.
• There is no blanket or standing order handling. A PO drawn against in releases over several months, or one filled by partial deliveries, needs each release or delivery tracked against the same number outside this tool.
• The acknowledgement block is somewhere to sign, not a legal opinion. Whether an accepted purchase order forms a binding contract, and on what terms, depends on your state, the wording, and what else passed between you and the supplier.
• The tax field applies one flat rate to the whole document, which is rarely what a purchase order needs — sales tax on a subcontract is usually the supplier's to state on their invoice, not yours to assert on the order.

Disclaimer. This tool produces a business document, not legal advice. Whether an accepted purchase order is binding, what remedies exist if a supplier does not deliver, and how a signed acknowledgement interacts with any other agreement between you all depend on your state law and the wording you use. Confirm with a qualified professional before relying on it for an order large enough to matter.

Frequently asked questions

Who issues a purchase order — the buyer or the seller?

The buyer. This is the reverse of an invoice or an estimate, and it is the thing people most often get backwards. If you are subcontracting work, you write the purchase order and the subcontractor is the supplier on it. If a client sends you one, they are buying and you are the supplier — you do not raise a PO for your own work, you quote theirs on your invoice.

What happens if I invoice without the PO number?

At a company that uses purchase orders, the invoice fails the automated match and lands in an exception queue. It is not refused and you are usually not told — it simply is not paid until somebody works through the queue by hand. This is the most common reason a freelance invoice goes quiet, and it is entirely preventable: get the number before you invoice and put it on the invoice where they expect it.

What is a three-way match?

Accounts payable compares three documents before releasing money: the purchase order, a record that the goods or work were received, and the invoice. If the quantities and prices agree across all three, payment is scheduled automatically. If any leg is missing or disagrees, the invoice becomes an exception. As the buyer, the leg you are most likely to forget is the receiving record — confirming in writing that the work arrived.

Is a purchase order a contract?

A purchase order is an offer to buy on stated terms, and it generally becomes binding when the supplier accepts it — by signing the acknowledgement, confirming in writing, or simply starting the work. That makes an accepted PO stronger than an approved estimate, because the commitment runs from the party with the money. How far it binds still depends on your state and the wording, and any separate contract between you will usually take precedence over it.

Do I need to issue purchase orders as a freelancer?

Not for your own work. They earn their place the moment you start buying — a subcontractor, a print run, a stock licence, a photographer on a shoot you are producing. At that point a PO fixes the quantity, price and date before the money is spent, and gives you a single reference to match the eventual bill against. For a one-off under a few hundred dollars an email is fine; for anything you would be annoyed to be over-billed on, issue the order.

The supplier wants to change the price after I sent the PO. What now?

Issue a revised purchase order, or a written change to the existing one, before the work continues — and keep the same number with a revision marker so the eventual invoice still matches. Paying an invoice that exceeds the open PO is exactly the case the match is designed to catch, and at a larger company it will be stopped whether or not you personally agreed to it. Agreeing a change verbally and hoping the invoice slips through is how an order ends up unpayable.
