Invoice review
A buyer checklist for reviewing a China supplier proforma invoice before sending a deposit or balance payment.
A proforma invoice is a payment trigger. Treat it as a verification document, not only an accounting attachment.
The proforma invoice usually contains the seller name, product description, quantity, price, bank details, shipment terms, and delivery assumptions. If those details conflict with the supplier file, finance can send money to the wrong entity or approve terms the purchasing team did not intend.
A practical file should name the legal entity, show the documents compared, and record the person who gave each answer. Keep the contract draft, invoice, bank instruction, supplier emails, screenshots, and any revised document in one folder. If a document changes, keep the old version. That is often where the risk pattern appears.
The file should also explain the business decision. A buyer may accept a small inconsistency for a low-value sample order and reject the same inconsistency for a large deposit. Write down the exposure, the unresolved point, and the safeguard used.
Do not approve payment because the invoice looks professional. Approve it because the entity, payment route, product, and terms connect to the supplier file.
A useful result does not need dramatic language. It should tell procurement and finance whether to proceed, pause, request documents, change payment terms, or escalate to counsel.
The review depth should match the money at risk. For a small sample, the buyer may only need identity, payment route, and basic document consistency. For a tooling deposit, repeat order, private-label product, or long-term supplier relationship, the buyer should add ownership context, public-risk records, production-site evidence, and a written supplier explanation for any mismatch.
Do not let the supplier's urgency decide the depth. The buyer should decide before payment which unanswered questions are acceptable and which questions block approval.
Escalate when the supplier avoids legal names, refuses to explain a payment route, changes the contracting party late, or asks the buyer to accept a document that does not match the transaction. Escalation means the buyer needs a more senior decision before money or commitment moves.

Start with the Chinese legal entity, then compare it with the contract, invoice, payment route, website, and supplier explanation.
No. It shows the buyer needs stronger evidence before payment, onboarding, or escalation.
Record what matched, what conflicted, what remains unsupported, and what action the buyer approved.
Use this before payment or onboarding.
Keep a record finance can review.
Choose the right depth for the decision.
For this topic, keep the review tied to the actual order rather than a general supplier profile. In the case of Proforma invoice check before paying a China supplier, the buyer should write down the exact decision it needs to make: whether to pay, sign, ship samples, accept a document, or escalate the file for management approval.
Before finance releases money, the buyer should match the legal supplier name, invoice issuer, beneficiary name, bank location, and the person who sent the payment instruction. A mismatch does not prove fraud by itself, but it does require a written explanation that names each company and its role in the transaction.
Keep the first payment instruction, any later change notice, the supplier's explanation, and the final internal approval in one folder. If the buyer must dispute a transfer, ask for a recall, or explain the case to management, the file should show who approved the risk and which records supported that approval.
Buyers should also keep the rejected path visible. If the supplier could not explain a record, refused to identify the right company, or sent a document that did not match the order, write that fact into the file. A rejected explanation can matter as much as an accepted document because it shows how the buyer controlled the decision.
