What a proforma invoice is (and isn't)

A proforma invoice is the bill before the bill — a preliminary document you send ahead of delivering goods or services. It looks like an invoice and carries the same details, but it isn't a demand for payment and it isn't a tax invoice. Buyers use it to arrange advance payment, get a purchase approved internally, or estimate customs duties before a shipment moves.

To make one here, prefix the number so it can't be confused with your real invoice sequence — PRO-001, PRO-002 — and write "Proforma Invoice — not a tax invoice" at the top of the notes field. List the goods or services as line items exactly as they'll appear on the final invoice, with quantities, unit prices, and any discount, so the buyer is approving the actual numbers rather than a rough estimate. If you charge VAT, GST, or sales tax, you can show the expected rate too — just remember the proforma itself isn't valid for input credit.

A proforma doesn't create a receivable in your books — record the sale when you issue the real invoice on delivery. When that moment comes, the conversion takes a minute: your draft autosaves in the browser, so switch the prefix to your normal invoice sequence, update the issue and due dates, remove the proforma note, and download the final PDF.

Which document does a purchasing office raise a PO against?

A university lab has chosen an instrument, but the purchasing office cannot raise a purchase order without a formal document to attach it to. So Calder issues a proforma: the same lines the real invoice will carry, priced as quoted, with the accessories and the qualification visit itemised so the buyer's committee can see exactly what sits inside the capital request. The preventive maintenance plan is quoted two years ahead, which is why that one line carries a quantity of 2. Nothing here is payable yet — this is a document to buy against, not a bill.

Every line is priced exactly as it will appear on the invoice that follows shipment, because the purchase order the buyer raises gets matched against it line for line — and the tax line stays empty because the university's sales-tax exemption certificate is on file.

What keeps a proforma from reading as a bill

  • The word proforma

    Open the notes field with "Proforma invoice — not a tax invoice" so nobody in the buyer's accounts payable queue files it as a bill that is already due.

  • A separate number series

    Use a PRO- prefix in the invoice number field so proformas never consume numbers from the sequential series your real invoices are filed under.

  • A validity date

    Say how long the prices hold — "valid 30 days from issue" in the notes — because component costs and freight move between quoting and shipping.

  • Payment and lead-time terms

    The notes field is where you set what actually triggers the work: prepayment in full, or a deposit with the balance before dispatch, and the lead time that starts when funds clear.

  • The buyer's reference

    There is no PO or quote-number field in this form, so put "PO to be quoted on the final invoice" or your quote reference in the notes, where the purchasing office will look for it.

Frequently asked questions

Is a proforma invoice legally binding?

No — a proforma is a preliminary document, not a contract or a demand for payment, and it isn't valid for VAT or GST input credit. The binding document is the final invoice you issue on delivery. Rules vary by country, so check with an accountant if you're unsure.

What's the difference between a proforma invoice and a quote?

Mostly formality — a proforma is laid out like the final invoice, with real line items, quantities, and totals, so the buyer approves the exact figures they'll eventually be billed. Quotes tend to be looser estimates; proformas are the standard format for advance-payment requests and customs paperwork.

Can I use a proforma invoice for customs?

Proformas are commonly used to estimate duties and start pre-clearance before a shipment moves, but most customs authorities require a commercial invoice for the actual clearance. Requirements vary by country and carrier, so confirm what your freight forwarder needs.

How do I turn the proforma into the final invoice?

Your draft autosaves in the browser — reopen the page, change the number from the PRO- prefix to your normal invoice sequence, update the issue and due dates, delete the proforma note, and download the new PDF. That final invoice is the one that goes in your books.
