In short: a proforma invoice is a formal quotation in invoice format. It must be specific enough for the buyer's bank and customs broker to act on: exact goods, HS code, quantities, price, currency, Incoterm with a named place, payment terms, shipment date and validity.

Common questions

Is a proforma invoice a tax invoice?

No. A proforma invoice is a quotation in invoice form. It confirms the terms before shipment, so the buyer can pay an advance, open a letter of credit or apply for an import licence. The commercial invoice is issued at shipment.

Does a proforma invoice need an HS code?

It is strongly recommended. Banks, importers and customs brokers use the HS code to check duty and licences, and it should match the code on your shipping documents.

How long should a proforma invoice be valid?

Usually 15 to 30 days, because freight rates, exchange rates and raw material prices move. State the validity date clearly.

Can a letter of credit be opened against a proforma invoice?

Yes. Buyers commonly open an LC based on the proforma, so every detail on it, such as the description, Incoterm, quantity and shipment date, should be something you can match exactly at shipment.
