Proforma Invoice Guide: What It Is and When to Use It
Everything importers, exporters, and international businesses need to know about proforma invoices
A proforma invoice is a preliminary bill of sale that plays a crucial role in international trade and business negotiations. Unlike a regular invoice, it is not a demand for payment — instead, it provides buyers with detailed information about a potential transaction before it is finalized. This guide explains what proforma invoices are, when to use them, and how to create them correctly.
What Is a Proforma Invoice?
A proforma invoice is a preliminary document sent by a seller to a buyer before a sale is confirmed. It describes the goods or services to be provided, their quantities, and estimated prices. The term 'proforma' comes from Latin meaning 'as a matter of form' — it is a formal document but not a final invoice. Proforma invoices are commonly used in international trade, import/export transactions, and for obtaining buyer approval before proceeding with an order.
Proforma Invoice vs. Commercial Invoice
A proforma invoice is issued before the transaction is finalized and is used for quotation, customs, or buyer approval purposes. A commercial invoice is issued after the transaction is complete and is the actual request for payment. Key differences: proforma invoices are not legally binding payment demands, they may contain estimated prices that could change, and they are often used to obtain import licenses or letters of credit before the actual shipment.
Essential Elements of a Proforma Invoice
A professional proforma invoice should include: a unique proforma invoice number (e.g., PI-2026-001), seller and buyer details, issue date and validity period, incoterms (international shipping terms such as FOB, CIF, EXW), country of origin of the goods, itemized list of products with quantities, unit prices, and total value, currency, payment terms, and any applicable taxes or duties.
Understanding Incoterms
Incoterms (International Commercial Terms) are standardized trade terms published by the International Chamber of Commerce that define the responsibilities of buyers and sellers in international transactions. Common incoterms include: FOB (Free on Board) — seller delivers goods to the port, buyer pays shipping; CIF (Cost, Insurance, Freight) — seller pays shipping and insurance to destination port; EXW (Ex Works) — buyer is responsible for all transportation from seller's premises; DDP (Delivered Duty Paid) — seller delivers goods to buyer's location, paying all duties and taxes.
When to Use a Proforma Invoice
Use a proforma invoice in these situations: when a buyer needs to arrange financing or a letter of credit before placing an order; when importing goods that require customs pre-clearance; when a buyer needs to obtain an import license; when providing a formal quotation for international trade; when a buyer wants to confirm the details of an order before committing; and when goods are being sent as samples or gifts (to declare value for customs).
Validity Period and Best Practices
Always specify a validity period on your proforma invoice (typically 15-30 days). This protects you from price changes in materials, currency fluctuations, or shipping costs. Once the buyer accepts the proforma invoice and places an order, issue a commercial invoice for the actual payment. Keep copies of all proforma invoices for your records, as they may be required for customs or dispute resolution.
FAQ

Yes, proforma invoices are commonly used for customs purposes, especially when goods are being sent as samples, gifts, or for temporary import. Customs authorities use the proforma invoice to assess the value of goods for duty calculation purposes.

A quotation is an informal price estimate, while a proforma invoice is a more formal document that resembles an actual invoice. Proforma invoices are typically used in international trade and include more detailed information such as incoterms, country of origin, and validity period.
