What is a Proforma Invoice and When Should You Send One?

Published on November 19, 2025

In the world of invoicing, the "Proforma" is a unique document. It sits somewhere between a Quotation and a Commercial Invoice. Using it correctly can speed up customs clearance and secure upfront payments.

Proforma Invoice Definition

A Proforma Invoice is a preliminary bill of sale. It is sent to a buyer before the goods are shipped or delivered.

Unlike a standard invoice, a Proforma Invoice is not a legal demand for payment (and therefore, you don't use it for accounting/tax purposes yet). It creates a "good faith" agreement on the price and quantity.

When to Use It

  • International Trade (Customs): Customs agents often require a Proforma Invoice to calculate duties and taxes before the goods arrive.
  • Securing Financing: A buyer might need a Proforma Invoice to show their bank to get a Letter of Credit to pay you.
  • Advance Payments: If you require a deposit before starting work, you send a Proforma Invoice to request that payment.
