Proforma Invoice vs Commercial Invoice Explained

What each document is for

When you receive a proforma invoice, you're looking at a quote. It outlines products, quantities, pricing details, and sales terms before anything is finalized. There's no commitment to supply, it's simply the offer you asked for. The commercial invoice, on the other hand, goes out after the deal is closed and goods are ready for shipment. Customs officials and finance teams expect it as the main proof of sale and value. So, if you're matching up proforma invoice vs commercial invoice, it comes down to when they show up and their legal weight.

You'll notice most sections overlap, each describes the shipment and deal in full. But the proforma serves as a request or offer, not evidence that anything was delivered or billed. Customs rarely, if ever, accept a proforma in place of a commercial invoice for import clearance.

When each invoice is used

Proforma invoice: You'll use this to give or request a quote, ask a buyer to prepay, apply for import paperwork, or help your customer prepare to fund an order. It's not a demand for payment.
Commercial invoice: This is sent when goods actually leave the seller's warehouse. The buyer pays from this document, banks process transfers using it, and customs authorities need it to check duties and confirm the shipment.

It's common for importers to receive a proforma during the early stages, maybe even before a contract is signed. As soon as the goods are packed and dispatched, the seller creates the commercial invoice. Bear in mind, some countries add requirements, asking for import permits or accompanying certificates for certain items. Always double-check the rules at the destination port.

What each invoice should contain

You'll need both invoices to list seller and buyer details (full addresses), a clear breakdown of each product, the quantity, price per unit, overall total, and the correct currency. On a commercial invoice, you'll nearly always see the Incoterm used, shipping route info, country where the goods were made, payment instructions, and a reference tying it back to a purchase order or contract. Depending on what you're shipping and where, governments may set different document standards. If you're unsure, ask your freight forwarder or customs agent before proceeding.

Every proforma must say it's a "proforma invoice." It's not an alternative to an official commercial invoice for customs, using the wrong one could hold up your goods and payment in transit.

You'll want to keep both forms in your order records. The proforma shows your intent and offered terms, while the commercial invoice proves what was actually shipped and billed. That way, you're covered if questions arise from your customer or the authorities.

Frequently asked questions

Can a proforma invoice be used for customs?

Usually, you can't use it as the primary document. Customs agents almost always require a commercial invoice as proof of finalized sale and shipment value. Sometimes, a proforma will help for import licensing or preliminary procedures, but you'll need to confirm with your broker or the customs authority for your goods and destination.

Does a proforma invoice create a payment obligation?

Standing alone, a proforma invoice doesn't mean payment is owed. If you and your customer both agree to its terms in writing, it might be used for prepayment arrangements. Everything depends on what the document says and whether there's a contract in place. Only treat it as binding if you have clear written acceptance from both sides.
