What is a Proforma Invoice? Meaning, Purpose, and Use in Exports

A proforma invoice is a preliminary bill of sale sent to a buyer before a transaction is completed. It outlines the details of the proposed sale—including the products or services, quantities, value, delivery information, and payment terms—but it’s not a legally binding document or a formal demand for payment.

“Pro forma” is Latin for “for the sake of form.” This guide by EximPe serves as an estimated invoice or quote, establishing the seller’s intent and detailing what the buyer should expect once the transaction is finalized. It’s especially important in international trade, where clarity on goods, costs, and terms is critical.

Why Use a Proforma Invoice? (Purpose & Meaning)

Clear cost estimate before sale

This document acts like a formal quote that helps the buyer plan budget, arrange financing, or open a letter of credit—especially important in international trade.

Negotiation & agreement tool

Once the buyer confirms intent, the seller sends a proforma invoice to finalize details like price, delivery terms, and quantity before moving to transaction.

Customs & trade documentation

Customs authorities often require a proforma invoice to assess duties, verify shipment value, or approve import licenses. It helps clear goods even before a formal commercial invoice exists.

Proforma Invoice vs Commercial Invoice vs Quote

It's important to distinguish a proforma invoice from other common documents:

• Proforma Invoice vs. Quote: A quote is a simple estimate. A proforma invoice is a more detailed, quasi-formal document used when the buyer's intent to purchase is strong, acting as a preliminary sales agreement.
• Proforma Invoice vs. Commercial Invoice:
  • Proforma: Issued before shipment, non-binding, estimated costs, not for accounting/tax.
  • Commercial: Issued after shipment, legally binding, final actual costs, used for customs clearance, accounting, and formal payment request.

When Should Exporters Use a Proforma Invoice?

• During negotiation after a buyer has signaled intent but before shipment.
• Whenever the buyer needs to apply for a letter of credit or arrange foreign exchange.
• If customs authorities require document for import permit, pre-shipment inspection, or duty estimation.
• When advance payment or internal purchase approvals are needed.

What Should a Proforma Invoice Include? (Format)

A well-drafted proforma invoice typically includes:

• Title Clearly Marked “Proforma Invoice”
• Date of Issue and Validity Period
• Seller’s Name, Address, and Contact Information
• Buyer’s Name, Address, and Contact Information
• Unique Invoice Number
• Item Descriptions (goods/services)
• Quantities, Unit Prices, and Total Amount
• Currency for Transaction
• Expected Delivery Date and Shipping Terms
• Applicable Taxes, Duties, and Additional Charges
• Payment Terms and Methods
• Country of Origin (especially important for exports)
• Signature of Seller (optional but recommended)

Pro Tip: Always clearly label the document as a “Proforma Invoice” to avoid confusion with commercial or tax invoices.

• Initial Documentation: Initiates the export process once terms are agreed upon between the buyer and seller.
• Customs Clearance: Needed for import/export paperwork and to estimate duties and taxes.
