China supplier bank account change after PO approval

A bank account change after PO approval deserves its own buyer file. The supplier has already agreed to price, delivery, entity name, and payment terms. When the bank details change after that point, finance should treat the request as a fresh payment decision rather than a small clerical update.

The risk sits in the gap between the approved supplier and the party that will receive money. The new account may belong to the same legal entity. It may also belong to a trading partner, a related company, a branch, a personal contact, or an attacker who has entered the email thread. The buyer cannot judge that by tone. A familiar salesperson can still forward a weak instruction.

The file should start with a simple comparison. Record the old beneficiary name, old account number, old bank, new beneficiary name, new account number, new bank, date of the request, and person who sent it. Add the PO number and proforma invoice version. That first table gives the review a shape before anyone argues about urgency.

Do not let the supplier describe the change in loose language. Words such as finance adjustment, internal settlement, tax reason, or bank maintenance do not explain who will owe the buyer goods or money after payment. Ask the supplier to name the legal account holder and explain how that holder connects to the company named in the PO.

Finance teams often jump straight to callback verification. That matters, but the entity question comes first. The buyer should compare the new beneficiary against the business license, contract party, invoice issuer, company seal, and any earlier payment record. A callback only confirms that a contact approves the instruction. It does not prove that the new payee has legal responsibility for the order.

If the beneficiary matches the registered Chinese company, the file can move to bank and communication checks. If the beneficiary differs, procurement should ask for a written relationship explanation. The supplier should say whether the payee is a branch, export company, group company, collection agent, or unrelated service provider. The buyer should not supply the answer for them.

A callback should use a known channel that existed before the bank change request. Call a phone number from the earlier onboarding file, not the number in the new email. Use a known company domain, prior contract contact, or previously verified manager. Ask the contact to read the new beneficiary name and final four digits of the account number. Do not read the details first and invite a yes.

The callback note should name the person reached, the number or channel used, the time, the details confirmed, and the question that remained open. A screenshot of a chat message helps less than a short note written by the buyer. Screenshots can sit in the file, but finance needs a decision record it can read without reconstructing the whole conversation.

A bank account change can point to fraud, but not every mismatch is a fraud case. Some Chinese suppliers use export companies or offshore accounts for foreign-currency handling. Some factories ask a related trading company to collect payment because the factory lacks the right banking setup. Those arrangements can be real. They still create commercial risk for the buyer.

The buyer should ask one practical question: if goods fail, delivery stops, or a refund becomes necessary, which company will answer? If the supplier wants payment to another entity, the file should show whether the original supplier still accepts refund, warranty, quality, and document duties. That statement should come before payment, not after a problem appears.

Bank change review should not live only inside finance. Procurement knows who negotiated the order. Quality knows whether production has started. Logistics may know whether shipment pressure is real. A rushed request often lands with finance because payment is the visible action, but the risk belongs to the whole order file.

A short routing note helps. Procurement confirms supplier identity and relationship. Finance confirms bank details and payment controls. Management approves any third-party collection or unusual route.

Approval should stay narrow. Write: finance may use this account for PO 4582, deposit amount USD 12,000, after receiving the supplier's signed account-change letter and callback note. That wording tells the team what it approved and what it did not approve.

Avoid broad wording such as new bank approved or account changed. Broad wording can follow the supplier into the next order, a larger balance payment, or a different invoice. If the supplier changes the account again, the buyer should open a new file. Repetition is a signal, even when every single request has an explanation.

Keep the original PO, original PI, old bank instruction, new bank instruction, business license, account-change request, supplier explanation, callback note, and final approval line. If the beneficiary differs from the supplier, add the relationship statement and a note on refund responsibility. If the supplier refuses to provide that statement, record the refusal instead of leaving the file blank.

The buyer should also save the rejected path. If finance asked for a signed letter and the supplier sent only a WeChat screenshot, keep that screenshot beside the request. A later reviewer should see why payment paused.

Stop the payment when the supplier refuses to name the beneficiary, pushes a personal account, changes the email thread, avoids a known callback route, or asks for same-day payment with no written explanation. Stop it when the bank country, beneficiary, invoice issuer, and contract party point to different places and no one owns the mismatch.

A stop does not need drama. It can be a plain finance hold: payment remains blocked until the supplier confirms the account through a known channel and the commercial owner accepts the payee relationship. Buyers who write holds in plain language usually resolve them faster because the supplier can see the missing item.

The final note should fit on a screen. It should say what changed, who confirmed the change, what evidence supports the new account, what risk remains, and which order step the buyer approved. If the file runs longer than that, put documents in the folder and keep the decision note short.

A clean account-change file does not make the supplier risk-free. It gives the buyer a record that finance, procurement, and management can stand behind. For large deposits, new suppliers, related-company collection, or offshore accounts, pair the bank review with a wider company verification file.
