Safe Payment Terms for Importers: Verify Supplier Bank Changes Before Paying

Safe payment terms for importers must address more than deposits, shipment milestones and credit periods. Before releasing an overseas supplier payment, you need confidence that the receiving account belongs to the agreed beneficiary—or to a third party whose authority to receive payment has been independently established. Otherwise, even a carefully negotiated purchase can end with funds sent to the wrong account.

For procurement, finance and trade operations teams, the priority is payment-instruction integrity: establishing approved details, controlling changes and retaining evidence that each transfer was authorized.

The overlooked risk: a real supplier, false payment instructions

You can inspect a factory, approve samples and receive genuine shipping documents while still being exposed to fraudulent bank instructions.

An attacker may impersonate a supplier using a lookalike email address, compromise a real mailbox or insert altered payment details into an invoice. A message can appear within a familiar conversation and still contain an unauthorized beneficiary change.

The supplier itself may also request payment to an account that your team has not assessed. That is not automatically fraud, but it creates a separate question: will paying this recipient satisfy your obligation to the contracted seller?

Negotiated terms govern when and under what conditions you pay. They do not, by themselves, authenticate the receiving account.

Safe payment terms for importers start with an approved beneficiary

Before the first payment, create an approved beneficiary record linked to the supplier’s legal entity and contract. Treat this as a controlled finance record, not information copied from the latest invoice.

Establish the baseline

Collect and reconcile:

• The contracted seller’s full legal name, registered address and relevant registration identifier.
• The beneficiary’s account name and its relationship to the seller.
• The account number or IBAN, where applicable, and necessary bank routing details.
• The bank’s name, country and SWIFT/BIC where required.
• Authorized supplier contacts for commercial matters and payment instructions.
• Any approved third-party recipient and the supporting authorization.

Distinguish the seller’s trading name from its legal name. If the contract, invoice and account name differ, resolve the discrepancy before approval rather than assuming it is a harmless abbreviation.

Authenticate the initial setup

Supplier bank account verification must begin during onboarding. A callback is not independent if the phone number came only from the same unverified message as the bank instructions.

Establish contacts through independently corroborated company information and your supplier due-diligence process. Confirm that the person providing instructions is authorized to do so. Ask your bank what beneficiary-checking services are available for the destination. Availability and scope vary, so understand what each check actually confirms.

Store approved details in a restricted supplier master record, with the verification evidence and approval history attached.

Verify bank changes through an established channel

A request to change bank details should trigger a hold on the affected payment, not a quick administrative update. Apply the same rule whether the instruction arrives by email, invoice, messaging app or supplier portal.

Fraud involving supplier bank-detail changes often exploits urgency and familiarity. The message may reference a real order, explain that an account is under audit or claim that shipment depends on immediate payment.

Use a repeatable verification workflow

1. Pause the affected payment. Prevent the transfer and suspend any pending supplier-master update until verification is complete.
2. Compare old and new instructions. Identify changes to the beneficiary name, account, bank, country and intermediary details.
3. Contact the supplier independently. Use a previously established, trusted phone number or another separately authenticated channel—not contact details supplied in the change request.
4. Confirm the full instruction. Ask an authorized contact to confirm the reason for the change, when it takes effect, which invoices it covers and the complete beneficiary details. Do not settle for a general confirmation that the supplier changed banks.
5. Investigate inconsistencies. Escalate a new account country, unfamiliar recipient or unusual communication pattern. Where contact compromise is suspected, authenticate through an additional independent route.
6. Obtain separate approval. A second authorized employee should review the evidence before the master record changes or payment is released.
7. Record the outcome. Retain who confirmed the change, the channel used, the details verified and the approving employee.

Replying to the original email is not independent confirmation. Neither is calling a new number included in an attached bank letter.

If the supplier cannot be reached through a trusted channel, keep the affected payment on hold and explain the verification requirement. Escalate any contractual deadline or shipment consequences internally. A deadline is not evidence of authenticity.

Assess third-party beneficiary requests separately

Paying someone other than the contracted seller creates additional risks. Such arrangements can be legitimate, but they require more scrutiny than a routine account update.

Trading companies and related entities

A manufacturer may sell through a trading company, or a group may use a separate treasury entity. Establish which entity is the contractual seller and why another entity would collect payment.

If the trading company is already your seller, its account may be consistent with the transaction, subject to normal verification. If the contract names the manufacturer but payment is requested to another entity, obtain a documented explanation and independently verify the authorization.

A shared logo, similar company name or group relationship does not establish authority to collect a particular payment.

Factoring and receivables assignments

A supplier may assign a receivable to a factor or financing provider. Confirm the arrangement with the supplier through an established channel and authenticate the recipient separately.

Check which invoices are covered, the payment instructions and whether payment to that recipient discharges your obligation. Assignment requirements and legal effects can depend on the contract and applicable law; involve counsel when the arrangement is unclear, disputed or material.

Unexplained account-name mismatches

Requests involving personal accounts, unrelated businesses or unexplained jurisdictions warrant escalation. Do not rely solely on an invoice footnote or a letter that appears to be signed.

Require evidence of the relationship and authority to receive payment. Obtain legal and compliance review where appropriate, including applicable sanctions screening. If the explanation remains unresolved, do not approve the exception.

Put safeguards into contracts and accounts payable

International supplier payment security works best when supplier obligations and internal controls reinforce each other.

Contract provisions to discuss with counsel

Consider provisions that:

• Identify the approved beneficiary or reference a controlled payment schedule.
• Define authorized contacts and the process for notifying bank changes.
• Require independent verification before changed instructions become effective.
• Prohibit unapproved third-party payment directions, subject to applicable law.
• Address payment holds and due-date consequences while a change is being verified.
• Clarify when payment to an approved third party satisfies the buyer’s obligation.

Agree these procedures before a dispute arises. A verification policy alone does not necessarily excuse late payment under an existing contract.

Accounts-payable controls

Separate supplier-master maintenance from payment release. Where staffing permits, the person entering new bank details should not be the person approving that change or releasing the transfer.

Limit editing permissions, preserve an audit trail and require documented dual approval for beneficiary changes. Avoid letting staff overwrite approved details directly from an invoice during payment preparation.

Create an exception route with named approvers and recorded reasons. Urgency should determine escalation speed, not remove verification steps. Smaller teams can still require a second authorized reviewer before releasing a payment to a changed beneficiary or account.

Understand the limits of bank checks and test transfers

When verifying overseas supplier bank details, distinguish technical validation from account ownership and authority to receive payment.

An IBAN format or checksum check can detect some entry errors, while a routing-code check may identify a bank or branch. Neither proves that an account exists or belongs to your supplier. Bank name-matching services may identify discrepancies, but coverage and matching behavior differ across markets and payment channels.

Even an account-name match does not establish that a third party is authorized to collect a specific invoice.

A small test transfer can help check payment routing, but it cannot establish contractual authority. An attacker controlling the receiving account and communication channel may confirm receipt just as readily as a legitimate supplier.

Use bank checks and any test payments as supplementary controls—not substitutes for independent confirmation and approval. Do not send a test payment to bypass an unresolved fraud concern.

If a suspicious payment has already been sent

Contact your bank immediately through its official fraud or payment-support channel. Explain the suspected payment-instruction fraud and request urgent assistance with stopping, tracing, recalling or recovering the transfer, as applicable.

Provide the transfer reference, amount, currency, time, beneficiary details and reason for suspicion. Ask the bank to coordinate with the receiving institution where possible. Recovery is not guaranteed; options depend on the payment method, status and other circumstances.

At the same time:

• Stop further payments using the suspect instructions.
• Notify internal finance, security, legal and management contacts.
• Alert the genuine supplier through a trusted channel.
• Preserve original emails, headers, attachments, invoices, messages and approval logs.
• Investigate possible mailbox compromise and secure affected accounts.
• Follow applicable reporting requirements and relevant insurer notification procedures.

Preserve original evidence rather than relying only on screenshots. Coordinate evidence preservation and account security with the incident-response team, where available. Do not delay bank contact while attempting to complete the internal investigation.

Pre-transfer checklist

Before releasing funds, confirm:

• [ ] The payment relates to the correct contract and invoice.
• [ ] The beneficiary matches the approved supplier record.
• [ ] Every bank-detail change has been independently confirmed.
• [ ] Any third-party recipient has verified authority for this payment.
• [ ] Account-name, country and entity discrepancies are resolved.
• [ ] Applicable compliance checks are complete.
• [ ] Exceptions and their supporting evidence are documented.
• [ ] Required approvals are recorded.
• [ ] The final payment instruction matches the approved details.

An unresolved item should trigger a hold or formal escalation—not an informal assumption. Escalation should resolve the issue before payment is released.

Frequently asked questions

Is an email from the supplier’s usual address enough to approve new bank details?

No. A genuine mailbox can be compromised. Verify the change through a previously established, independently authenticated contact channel and require separate internal approval before updating details or releasing payment.

Can an importer safely pay a supplier’s trading company or factor?

Potentially, but first establish the recipient’s identity, relationship and authority to collect the specific payment. Confirm the arrangement independently and clarify whether payment discharges the debt to the seller. Obtain legal or compliance review where needed.

Does a successful test payment prove the account is safe?

No. It can help confirm routing or receipt, but it does not prove supplier ownership or authority to receive your invoice payment. Independent verification is still necessary.

What should we do if shipment depends on an immediate bank change?

Escalate verification promptly, but do not bypass it. Contact the supplier through a trusted channel, explain the hold and coordinate the shipment and contractual implications with the relevant teams.

Build safer supplier relationships

Payment security is an ongoing discipline, not a one-time onboarding check. Establish approved instructions early, verify every change independently and retain an approval trail.
