Pro forma invoice

A pro forma communicates expected costs before payment is due. Learn what it is, when to use one, and how it differs from an invoice.

Not a payment demand

A pro forma invoice shows estimated or planned charges—often before goods ship or services finalize. In many systems it is informational, not the final tax invoice.

Clients may use it for budgeting, import planning, or internal approval before they can issue a PO.

Label it clearly as “Pro forma” so accounts payable does not treat it as currently payable by mistake.

When a pro forma is useful

Import planning, client budgeting, previewing totals before you issue the real invoice, or helping a buyer secure financing or approvals.

Example: you send a pro forma for a equipment package totaling $12,400 including estimated freight. After confirmation, you ship and issue the commercial/final invoice.

Service businesses sometimes use pro forma language for deposit previews—though a clear quote plus deposit invoice is often cleaner.

Pro forma vs quote vs final invoice

A quote emphasizes offer and acceptance. A pro forma emphasizes a preview of invoice-like totals and line items. A final invoice requests payment and may carry tax implications.

Use the document your client’s process recognizes. Some international buyers specifically ask for a pro forma; others want a quote PDF.

Never rely on a pro forma alone for your receivable tracking if payment is actually due—issue a real invoice when the obligation starts.

What to include

Seller and buyer details, line items, estimated quantities and prices, currency, validity or expiry if relevant, and a clear “Pro forma – not a tax invoice / not a demand for payment” style note when appropriate.

If customs will eventually need values, make descriptions and origins as accurate as you can even at the pro forma stage.

Number pro formas in a separate sequence (PF-2026-014) so they are never confused with INV-2026-014.

What to do next

Add a pro forma template for clients who request one, and keep your standard invoice template for actual collection.

Train yourself to ask: “Do you need this for approval/customs preview, or should I send a payable invoice?” That one question prevents document mix-ups.

When the deal is firm and payment should start, convert the preview into a proper invoice in AI Invoice Generator and send payment instructions.
