What a proforma invoice is, how it differs from a final invoice and a quote, the exact format customs and buyers expect, and a free generator to produce one.

A proforma invoice is a preliminary invoice sent to a buyer before goods are shipped or services delivered. "Pro forma" is Latin for "as a matter of form": the document looks like an invoice and carries the same information, but it is issued in advance, as a commitment of what the final bill will contain. It is not a demand for payment and it is not recorded as a sale in the accounts.
Buyers use it to approve an order, obtain internal sign-off, arrange financing or open a letter of credit. Importers use it to apply for import licences and to estimate customs duties before the shipment leaves.
| Document | When | Binding? | Goes in the accounts? |
|---|---|---|---|
| Quote or estimate | Before the sale, often before details are fixed | No | No |
| Proforma invoice | After the buyer has decided, before delivery | Not legally, but it states the exact terms | No |
| Final (commercial) invoice | On or after delivery | Yes, it is a demand for payment | Yes |
A quote can be rough. A proforma is precise: exact items, quantities, prices, taxes, delivery terms and validity. The final invoice should match the proforma unless something changed and both sides agreed.
The free proforma invoice generator has a field for each of these, produces a PDF with the correct title and wording, and lets you convert the same details into the final invoice later. If you prefer to edit a file, the invoice templates page has proforma versions in Word and Excel.
