What this decision should produce
These documents may look similar, but they serve different moments in the transaction and should not be treated as interchangeable.
Maintain a visible revision trail from the accepted proforma invoice to the final commercial invoice. If quantity, price, currency, Incoterm, shipper, consignee, or product description changes, confirm that the purchase order, payment records, packing list, transport documents, and customs entry remain consistent. Banks, brokers, and destination authorities may apply different documentary requirements, so verify the required invoice wording before shipment. The safest process uses one approved transaction data set and records every authorized change instead of recreating each document independently.
Use the proforma invoice before the final sale record
A proforma invoice is commonly used to summarize a proposed transaction before shipment. It can show seller, buyer, products, quantities, unit prices, total, currency, Incoterm, payment terms, lead time, and bank details. Buyers may use it to arrange a deposit, internal approval, foreign-exchange process, or import preparation, depending on local rules.
Because it is preliminary, clearly label it as proforma and give it a number, date, and validity period. Record which product specification and quotation it reflects. Changes to quantity, price, packaging, freight, or terms should create a controlled revision rather than an informal edit with the same file name.
Issue the commercial invoice for the actual shipment
The commercial invoice records the goods and values for the completed commercial shipment and is a key customs and accounting document. It should reflect the actual seller, buyer, products, quantities, values, currency, origin, Incoterm and named place, and other required declarations. Requirements vary by destination and product, so the customs broker should review the expected fields.
The invoice should align with the final packing list and transport data. If the shipment is short, split, replaced, or includes free samples, the documents must explain the real transaction consistently. Do not simply reuse the proforma without checking every field against the packed goods.
Keep value, payment, and customs roles separate
A deposit may be paid against a proforma invoice, but customs normally requires final commercial documentation. Customs value may also depend on assists, royalties, freight, insurance, related-party adjustments, or local valuation rules beyond the face value. A document generator cannot determine the correct customs treatment.
For payment security, verify bank beneficiary details through a known channel and investigate any late change. The beneficiary, contracting seller, exporter, and factory may differ for legitimate reasons, but those relationships should be documented and understood.
Reconcile both documents with the order
Compare the proforma and commercial invoice to the purchase order and amendments. Check product revision, quantity, unit price, tooling or sample charges, freight inclusion, discount, currency, Incoterm, and payment received. Explain approved differences so finance, customs, and receiving teams do not treat them as errors.
Keep both documents in the order history. The proforma shows the planned commercial basis, while the commercial invoice records the shipment. Together with the PO, packing list, payment evidence, and transport document, they provide a traceable transaction record.
How the decision works in practice
A supplier issues PI-104 for 1,000 units at USD 4.80 FOB Shanghai, with a 30 percent deposit. During production, 20 units fail and cannot be replaced before the shipping window. The final commercial invoice records 980 units and the adjusted value; the packing list also totals 980. The buyer retains the proforma, PO amendment, inspection record, final invoice, and payment reconciliation so the difference is documented.
What should be true before you continue
Maintain a visible revision trail from the accepted proforma invoice to the final commercial invoice. If quantity, price, currency, Incoterm, shipper, consignee, or product description changes, confirm that the purchase order, payment records, packing list, transport documents, and customs entry remain consistent. Banks, brokers, and destination authorities may apply different documentary requirements, so verify the required invoice wording before shipment. The safest process uses one approved transaction data set and records every authorized change instead of recreating each document independently.
Turn the review into a decision record
Do not mark an item complete because it was discussed. Record the current source, revision, date, owner, and remaining uncertainty so another person can understand why the order moved forward.
| Confirm | Evidence to retain | Risk if unclear |
|---|---|---|
| Clear document type, number, date, and revision | Record the source, date checked, responsible person, current file or observation, and any exception that still needs approval. | Using an unlabeled proforma as a final invoice |
| Seller, buyer, and beneficiary identities | Record the source, date checked, responsible person, current file or observation, and any exception that still needs approval. | Copying planned quantities into final documents |

| Incoterm and named place | Record the source, date checked, responsible person, current file or observation, and any exception that still needs approval. | Ignoring bank-beneficiary changes |
| Payment terms and amount paid | Record the source, date checked, responsible person, current file or observation, and any exception that still needs approval. | Assuming invoice value alone determines customs value |
| Specification or PO reference | Record the source, date checked, responsible person, current file or observation, and any exception that still needs approval. | Allowing invoice and packing-list totals to conflict |
| Final shipped quantity and value | Record the source, date checked, responsible person, current file or observation, and any exception that still needs approval. | Using an unlabeled proforma as a final invoice |
| Origin and customs-required fields | Record the source, date checked, responsible person, current file or observation, and any exception that still needs approval. | Copying planned quantities into final documents |

Ask for the information in one controlled message
Replace the bracketed details, remove any item that does not apply, and ask the supplier or project owner to identify deviations instead of replying with a general confirmation.

Frequently asked questions
Is a proforma invoice a tax invoice?
Usually not, but treatment varies by jurisdiction. Confirm accounting and tax requirements with qualified local professionals.
