Supplier Bank-Detail Change Verification Controls in the UAE

Supplier bank-detail changes are a high-risk point in the accounts-payable process because a valid invoice can still be paid to the wrong account. A UAE business should use a documented hold-and-verify workflow that separates the person entering the change from the person confirming it and from the person approving the payment.

Put every change request on hold

Do not update the supplier master or release payment directly from an email, messaging-app instruction or amended invoice. Log the request, supplier, affected entity, requester, receipt channel and pending payment exposure. Apply a visible hold until independent verification is complete. Urgency, seniority or pressure to avoid a late fee should not bypass the control.

Verify through a trusted channel

Contact the supplier using a phone number, portal or relationship contact already held in an approved record and established before the change request. Do not use a telephone number or link introduced in the same message that requested the change. Ask an authorised supplier representative to confirm the account name, bank, masked account identifier, effective date and business reason. Where risk warrants it, obtain a second verification through another established channel.

Separate maker, checker and payment approver

The maker records the request and supporting evidence. A checker independently reviews the source and callback evidence before approving the master-data amendment. The payment approver then confirms that the change passed the required control and that the payment file matches the approved master record. Access rights should prevent one person from completing all three steps.

Validate the first payment after a change

Flag the supplier for enhanced review on the first payment after the amendment. Compare the beneficiary in the payment file with the approved change record and consider a payment confirmation using the trusted channel. Review unusual countries, currencies, account-name mismatches, split invoices and last-minute changes. Do not treat a successful bank upload as proof that the beneficiary is legitimate.

Keep personal and banking data controlled

Bank details and contact evidence should be stored only in approved systems, with access limited to those who need it. Avoid copying full account data into open email threads or general chat channels. The UAE Government’s cyber-safety guidance reinforces the need for secure digital practices; the organisation should also apply its own privacy, retention and incident-response requirements.

Escalate suspected compromise

If a change appears fraudulent or a payment may have been diverted, stop further payments, notify the bank through authorised channels and activate the company’s incident-response process. Preserve the original message, headers, audit trail and approvals. Do not confront a suspected attacker from the compromised channel or delete evidence.

Accounts-payable checklist

1. Log and hold every bank-detail change request. 2. Verify through contact details established before the request. 3. Separate maker, checker and payment approver access. 4. Preserve the callback and approval evidence. 5. Apply enhanced review to the first payment. 6. Monitor master-data changes and payment exceptions. 7. Escalate suspected compromise immediately.
