Proforma invoice

A proforma invoice is a preliminary, quotation-style document a supplier sends a buyer before goods are delivered. It states the goods, quantities, prices and terms that will apply, so the buyer can confirm the order, arrange payment or obtain the paperwork needed for import.

How a proforma invoice is used

A proforma invoice looks like a normal invoice but is not a demand for payment; it is a good-faith estimate of what the final invoice will contain. In maritime supply it often follows a request for quotation, letting the buyer approve prices and terms before the chandler delivers.

Proforma versus commercial invoice

The proforma invoice comes first and is provisional; the commercial invoice is issued after delivery and is the actual request for payment. Keeping the two consistent, and tying both back to the original RFQ and delivery note, keeps a supply transaction clean.
