Bank account switch scams and China supplier payment checks

Source note: Based on public legal commentary about supplier invoice fraud and changed payment instructions. Source background.

Bank account switch scams work because they appear inside a real transaction. The buyer may already know the supplier, trust the contact, and be waiting for an invoice. The fraud arrives as a small operational change rather than a dramatic warning sign.

The attacker may spoof a supplier email, use a compromised inbox, or send a revised invoice that looks close enough to the original to pass a rushed review.

Before paying, compare the beneficiary name, bank location, currency, invoice issuer, contract party, supplier legal name, and email thread. A changed account should never be approved only because it arrived in a familiar email chain.

Use a known channel for confirmation. Do not reply only to the suspicious email. Call a known number, contact a previously verified person, or require a written explanation from the supplier's official domain.

Keep the original invoice, revised invoice, email headers if available, beneficiary details, approval messages, callback notes, and the exact timing of the payment change.

If the supplier claims the new account belongs to an affiliate or export company, ask for the relationship in writing before funds move.

Proceed only when the beneficiary and relationship are documented. Pause when the explanation is plausible but unsupported. Escalate when the supplier pressures payment, changes the account near a deadline, or refuses to confirm through a known channel.

For larger transfers, finance should treat bank changes as a control event, not a routine update.

The file should answer one question clearly: why did the buyer believe this account belonged in the transaction?

This note is buyer guidance, not fraud recovery or legal advice.

Many supplier-payment losses do not begin with a fake factory. They begin when a real relationship is diverted to a new account, a lookalike email domain, or a beneficiary that no one compared against the supplier file.

For China sourcing, the beneficiary check should sit beside company verification. The buyer should compare the legal supplier name, invoice issuer, account beneficiary, bank country, email domain, and any sudden change in payment instructions.

A supplier may have legitimate reasons to use a related trading company or offshore account. The issue is not that every difference is fraud. The issue is whether the supplier can explain the structure in writing before money moves.

When payment details change, stop using email alone. Confirm through a known phone number, a previous contact channel, or a second senior contact. Do not use the phone number or contact details inside the same suspicious message.

Keep the old and new bank details, the confirmation method, the name of the person who approved the change, and the reason for the change. This small control gives the buyer a record if the payment is later challenged.

If the supplier pressures the buyer to pay quickly, offers a discount for immediate remittance to a new account, or claims the old account is suddenly unavailable, treat the order as a live risk review rather than routine accounting.

Freeze the payment, notify finance, preserve email headers and attachments, and contact the supplier through a verified channel. If payment has already been sent, ask the bank for a recall immediately and preserve the timeline.

The supplier-verification file should then be updated. Add the suspicious instruction, the channel used, the beneficiary details, the confirmation outcome, and the final decision. Future orders should not restart from zero.

For this topic, keep the review tied to the actual order rather than a general supplier profile. In the case of Bank account switch scams and China supplier payment checks, 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.
