A pro forma invoice is formatted like a real invoice, with the same layout, the same fields, and sometimes the same amount. But it is not a request for payment and does not create a payment obligation. It is a preview, sent before the real thing.
What it's actually for
A pro forma invoice tells a client, in the exact format their invoice will eventually take, what they can expect to be billed. This is useful when they need that information before you are ready, or able, to issue the real invoice. Common reasons to send one:
- Before goods ship internationally, so the buyer has the documentation needed for customs, import permits, or arranging payment, before the sale is finalized. For the shipping paperwork side, see commercial invoice.
- Before a client's internal approval process, so they can get budget sign-off using a document that shows the real expected cost.
- As a payment request before delivery, in industries where full or partial payment is collected before goods or services are provided. The "real" invoice may only be issued after delivery is confirmed.
- For a bank or letter of credit, where the bank needs to see the expected value of the deal.
What makes it different from a real invoice
The critical difference is accounting status. In most systems, a pro forma invoice is not recorded as a receivable in your books, and the client does not record it as a payable in theirs. Nothing is technically owed yet. It states "here's what this will cost," not "here's what you owe." Accounting and tax treatment differs by country, so ask your accountant how pro forma documents should be handled in your records. Many authorities do not count them as tax invoices.
Side-by-side
| Pro forma invoice | Invoice | Quote | |
|---|---|---|---|
| Request for payment | No (unless you ask for prepayment) | Yes | No |
| Recorded as revenue | No | Yes | No |
| Sent | Before the sale is final | After delivery or milestone | Before agreement |
| Binding | Not by itself | Yes | Once accepted |
A quote is a pricing proposal. A pro forma invoice is closer to a final price in invoice format, often once the buyer has agreed in principle. See also invoice vs. receipt vs. quote.
Worked example: an export order
A small manufacturer agrees to sell 200 ceramic tiles to a buyer abroad.
- 200 tiles at $4.50 = $900.00
- Packaging: $60.00
- Shipping (estimate): $140.00
- Total: $1,100.00
The seller sends a pro forma invoice for $1,100.00 marked "Pro Forma Invoice, not a request for payment" with the buyer's reference, incoterms if used, and payment terms: 50% before dispatch. The buyer uses it to get an import permit and release the prepayment.
The buyer pays $550.00 (50% × $1,100). The seller ships. Actual freight turns out to be $155.00, so the final invoice shows:
- Goods and packaging: $960.00
- Shipping: $155.00
- Total: $1,115.00
- Less prepayment: −$550.00
- Balance due: $565.00
The final invoice states the difference of $15.00 from the pro forma. The client is not surprised by it because the change is noted.
Label it unmistakably
Because it is formatted identically to a real invoice, the words "Pro Forma Invoice" need to be clearly visible. Otherwise a client or their accounting system may mistake it for an actual bill and pay against a document that was never meant to be paid, or double-count it when the real invoice follows. Our proforma invoice generator labels this automatically.
Checklist for a good pro forma invoice
- Title it "Pro Forma Invoice" at the top.
- Use your own reference number, separate from your real invoice sequence (see invoice numbering).
- List the same items, quantities, and prices as the final invoice will show.
- State what is estimated (like freight) and what is firm.
- Add a validity date, since prices and rates change.
- State the intended payment terms and method.
- Note the planned shipment or delivery date.
- Tell the client to expect a final invoice after delivery.
Follow it with the real invoice
A pro forma invoice is never the final step. Once the transaction is confirmed (goods shipped, service delivered, terms finalized), issue an actual invoice referencing it. The two should match closely in amount and detail. If something changed, note the difference so the client is not caught off guard. Use the invoice generator and see what to include on an invoice for the required fields.
Common mistakes
- No label. The client pays or books it as a real invoice.
- Putting it in your invoice sequence. It creates gaps in the real numbering.
- Treating it as revenue. It is not income until a real invoice or payment exists, subject to local rules.
- Letting prices go stale. An old pro forma with outdated prices creates disputes.
- Using it for customs without checking. Customs may require a commercial invoice in a set format. Ask your carrier or broker.
FAQ
Is a pro forma invoice legally binding?
Not by itself. It may support an agreement if both sides rely on it, so word it carefully. Ask a lawyer when significant sums are involved.
Can I ask for payment against a pro forma invoice?
Yes, if you state clearly that prepayment is required. After payment, issue a proper invoice or receipt.
Does a pro forma invoice need a tax number?
Practice varies. Including your tax ID is a safe habit, but confirm local requirements with an accountant.
How is it different from a proforma in financial planning?
The term also describes projected financial statements. That is a different use. Here it only means a preview invoice.
A pro forma invoice exists to answer "what will this cost me?" before anyone owes anything. It is a courtesy and a planning tool, not a shortcut around sending a real invoice.
