Secure Payment Controls for Window and Door Orders from China

1. Map the five identities before the first payment

Record the legal seller, contracting party, manufacturing site, exporter of record and bank-account beneficiary as separate fields. They may legitimately differ, but the relationship must be explained and supported before money moves.

Start with the supplier evaluation guide, then obtain the contract, current registration evidence and bank instructions through controlled channels. A catalogue name, website brand or salesperson signature is not a substitute for the legal identity on the agreement.

2. Treat every bank-account change as a security incident

Do not verify a changed account by replying to the message that announced it. Pause the payment, use a previously verified phone or video contact, and require the agreed authorised documentation. A familiar email address is not proof that the sender or attachment is genuine.

The FBI’s Internet Crime Complaint Center describes business email compromise as a scheme that targets legitimate transfer requests and recommends verifying payment and purchase requests in person or by calling a known number. That principle matters even when the commercial request itself is real.

1. Stop the payment workflow and preserve the original message and attachment.
2. Contact the known representative using a number obtained before the change—not a number in the new message.
3. Confirm the beneficiary name, bank, account, currency and reason for change field by field.
4. Apply the buyer’s internal dual-approval and bank callback controls.
5. Issue a written verification record and update master data only after approval.
6. If funds were sent to suspicious details, contact the bank and the appropriate authorities immediately; do not wait for the supplier investigation.

3. Tie payment milestones to inspectable outputs

A date on a calendar is a weak release condition. A better milestone identifies the output, acceptable evidence, reviewer and consequence of a failed review. Deposits, custom finishes and material commitments may still be commercially necessary; the objective is to see what exposure each payment creates.

Separate evidence of activity from evidence of acceptance. A photograph of profiles in a workshop may show activity, but it does not by itself prove that the correct materials, quantities or approved configuration are ready.

4. Make deposit and refund conditions explicit

Write what the deposit authorises: design work, sample production, custom material purchase, production capacity reservation or mass production. Then state which amounts become non-refundable, at what event, and what evidence demonstrates that event.

A cancellation before custom powder coating is ordered is not the same as cancellation after profiles are finished or glass is cut. The contract should make that progression visible rather than arguing about a single word—deposit—after the fact.

• Amount, currency and due date
• Exact beneficiary and permitted payment channel
• Activities authorised by receipt
• Refundable and non-refundable portions
• Evidence of committed custom materials
• Effect of buyer or supplier delay
• Treatment of approved changes and rejected samples
• Refund method, bank charges and deadline

5. Control total exposure, not only the next invoice

Before approving a payment, calculate the buyer’s total unsecured exposure: money already paid, value of unverified work in progress, custom materials that may not be recoverable, and goods not yet under buyer-controlled shipment evidence. Compare that exposure with the buyer’s approved risk limit.

A low deposit percentage can still create high exposure if several orders overlap. Conversely, a higher payment may be rational when independently verified outputs and enforceable controls reduce uncertainty. The decision belongs to the buyer’s authorised commercial and finance process.

Exposure question: If the supplier stopped communicating today, what money, goods, documents and practical recovery routes would the buyer actually control?

6. Pre-review documentary-credit terms before issuance

A documentary credit is a document-based payment mechanism, not a factory-quality inspection. ICC explains that banks examine presented documents against the credit when UCP 600 applies. The buyer therefore needs documentary requirements that are clear, obtainable and aligned with the sales contract.

Review product description, latest shipment date, presentation period, partial shipments, transshipment, transport document, insurance document, certificate requirements and tolerance language with the issuing bank and trade-finance specialists before issuance. An impossible or ambiguous condition can create discrepancies without improving the goods.

• Does the credit expressly state the applicable rules?
• Can each required document be produced by the named party?
• Do descriptions and dates align across contract, invoice and logistics plan?
• Are partial shipment and transshipment provisions operationally realistic?
• Who pays amendment and discrepancy fees?
• What happens when the goods issue and documents issue are different?

7. Keep one payment decision record

Store the approved contract, beneficiary verification, invoices, account-change checks, milestone evidence, exceptions, approvals and bank confirmations under one order identifier. Do not leave the audit trail split across personal inboxes and chat groups.

Connect commercial payment decisions with the quotation comparison and the sample approval record. Scope, configuration and approval changes can alter both the amount due and the evidence needed before release.
