Commercial Invoice vs Proforma Invoice
Compare a commercial invoice vs proforma invoice, including purpose, timing, payment status, customs use, required details, and when to issue each document.
Last updated: 2 August 2026
The central difference between a commercial invoice and a proforma invoice is whether the document records final transaction details or presents expected terms before the transaction is finalized. They can look similar, but they should not be treated as interchangeable.
Carrier and destination requirements vary. Confirm which invoice is required for your shipment, especially for samples, temporary exports, repairs, gifts, or other non-sale movements.
Commercial invoice vs proforma invoice at a glance
Comparison | Commercial invoice | Proforma invoice |
|---|---|---|
| Primary purpose | Final transaction record and customs declaration | Preliminary quotation or good-faith estimate |
| Timing | Issued when goods are sold or ready to ship | Issued before the sale or final terms are confirmed |
| Values | Final agreed values and shipment charges | Expected or estimated values |
| Payment | May support an accounts-receivable obligation | Usually not a demand for payment |
| Accounting | May be recorded in the seller’s books | Normally not posted as a final sale |
| Customs use | Commonly used for import clearance | Sometimes accepted for specific non-sale or preliminary situations |
| Changes | Should match the goods and final transaction | Can be replaced when quantities, prices, or terms become final |
| Typical label | Clearly titled “Commercial Invoice” | Clearly titled “Proforma Invoice” |
What is a commercial invoice?
A commercial invoice is prepared for goods that have been sold or otherwise require final shipment values. It identifies the exporter, consignee, and sometimes the importer; describes each item; states quantity, HS code, country of origin, and value; and records currency, Incoterm, charges, and transport references.
Carriers and customs authorities commonly use the commercial invoice to understand the transaction and assess duties or taxes. The information should match the goods actually shipped and the supporting order, payment, packing, and transport records.
What is a proforma invoice?
A proforma invoice is a preliminary document supplied before final commercial terms are known. Sellers often use it to quote products, obtain buyer approval, support financing or an import permit, or describe a planned shipment. It may contain the same parties and item details as a final invoice, but its values and terms are still expected rather than final.
A proforma invoice should be clearly labeled so the recipient does not mistake it for a final demand for payment. Once the sale and shipment details are confirmed, the seller will commonly replace it with a commercial invoice.
When should you use each document?
Use a commercial invoice when:
- The sale is complete or the shipment details are final.
- The carrier or destination customs authority asks for final declared values.
- The buyer needs a final document for payment or accounting.
- The goods, quantities, prices, origin, and charges can be stated accurately.
Use a proforma invoice when:
- You are giving a quotation before the buyer confirms the order.
- A bank, licensing authority, or buyer needs expected shipment information.
- Prices, quantities, freight, or other terms may still change.
- A carrier permits it for a qualifying sample, repair, temporary shipment, or other non-sale movement.
The shipment purpose alone does not decide the document. For example, a sample may still require a commercial invoice with a reasonable customs value, while a destination may accept a proforma invoice for a particular temporary movement. Confirm the applicable rule instead of assuming.
Can a proforma invoice replace a commercial invoice?
Not automatically. A proforma invoice records an intention or estimate; a commercial invoice records final details. If customs or the carrier requires the final document, sending only a preliminary invoice can delay clearance. Likewise, issuing a final invoice while major terms are unresolved can create conflicting records.
When converting a proforma invoice into a commercial invoice, review every field rather than only changing the title. Confirm the invoice number and date, final quantities and prices, currency, Incoterm, payment and freight terms, transport references, package count, HS codes, countries of origin, charges, and certification.
Do both documents need a customs value?
International shipments normally need a value even when no money changes hands. A proforma invoice may show an estimated or good-faith value; a commercial invoice should show the final transaction value or another supportable customs value appropriate to the shipment. Never enter a token or zero value merely because goods are gifts, samples, returns, or repairs.
Which document should you create here?
CommercialInvoice.org creates a carrier-neutral commercial invoice, not a proforma invoice. Use the generator after the shipment details are sufficiently final, and verify the resulting document against your carrier and destination requirements. If the transaction is still at the quotation stage, prepare a clearly labeled proforma invoice elsewhere. Keep that proforma invoice for reference, then convert it only after reviewing the final terms.
