Vendor Bank Detail Change Verification Log

A vendor bank detail change verification log records how an accounts payable team confirmed a request before anyone edited the vendor master record. It should not duplicate the new banking instructions. Instead, it shows where the request arrived, which trusted contact route the verifier used, what the vendor confirmed, who approved the change, and how the case closed.

Keep account and routing numbers in the approved finance system or protected document repository. The working log needs restricted record identifiers, not another copy of the banking data.

Open one case for each request to add, replace, or reactivate payment details. Preserve the received message or form, but do not treat a familiar sender name, an old email thread, an attached letter, or urgent language as proof of authorization.

Retrieve a known contact method from a source that predates the request, such as the approved vendor master or an executed agreement. A phone number printed in the change request is part of the unverified evidence, so it cannot establish an independent callback.

The FBI's Internet Crime Complaint Center describes business email compromise as a scam that can use compromised business email accounts to cause unauthorized transfers. Its prevention guidance tells businesses to use a secondary channel or two-factor authentication to verify requests for changes in account information with the intended recipient. That recommendation supports the independent verification step in this workflow.

Fields that make a review possible

A reviewer should be able to reconstruct the decision without opening the coordinator's mailbox. These fields separate received evidence from verified evidence and expose unresolved cases.

Log field	What to record	What to keep out
Case ID	A unique internal reference	A bank account number
Vendor record	Approved vendor ID and legal name	An unverified display name
Request evidence	Received time, channel, sender, and protected file reference	Banking data copied into the log
Baseline contact source	System or agreement that supplied the known contact route	A number from the request
Verification attempt	Verifier, time, channel, contact used, and outcome	A note that only says called
Change confirmation	Confirmed, denied, corrected, or disputed	An inferred answer
Approval	Approver, decision, time, and policy reference	The preparer's assumed approval
System update	Editor, time, vendor record reference, and review state	Credentials or full bank details
Closure	Final state, closer, time, and evidence references	A closed label without evidence

Use controlled outcomes such as confirmed, denied, no answer, contact disputed, and referred to owner. Add free text for a specific discrepancy, but do not let a general note replace the outcome.

Verify from a trusted baseline

Freeze the requested change while verification is pending. Create the case and preserve the original evidence in its approved location before anyone edits the vendor record.

The verifier then retrieves the vendor contact from the baseline source named in the procedure. Contact details introduced by the request remain untrusted even when the message appears in a legitimate thread.

During the callback, do not read the proposed bank details and ask the contact to agree. Ask the authorized contact to describe the requested change through the organization's approved script, then compare the answer with the protected request evidence. Record the outcome without copying sensitive values into the log.

A confirmed request moves to the designated approver. A denial, disputed contact route, or conflicting answer stops the ordinary workflow and goes to the internal control owner.

Separate preparation, approval, and release

The requester asks for the change, the verifier checks it through a trusted route, the approver decides whether the evidence meets policy, and an authorized finance user updates the vendor master. The log names the person responsible for each action.

A small team may not have a different employee for every step. Its procedure should still identify prohibited role combinations and name the owner who resolves an overlap.

A virtual assistant can prepare the case, gather existing evidence, schedule a callback, use an approved script, and record the owner's disposition. The role should not approve an exception, infer policy, expose protected details in a general queue, or release a payment.

A completed callback does not close the case. Closure shows that the approved value reached the correct vendor record, any required review occurred, and the next payment remains subject to the organization's release controls.

Stop conditions and awkward cases

Stop when the only callback number came from the request, the established contact has left the vendor, the vendor asks to move the conversation to a personal address, or the callback answer conflicts with the submitted document. Record the conflict and the evidence checked without guessing which version is correct.

No answer is not confirmation. Keep the case pending, record each permitted attempt, and follow the written escalation or expiry rule instead of changing the record to meet a payment deadline.

Also stop when one person holds incompatible roles under company policy, the change accompanies an urgent payment release, or the baseline vendor record appears unreliable. The control owner decides what additional review is required.

A merger, factoring arrangement, legal name change, or assignment of receivables creates another boundary. A callback may confirm that the contact made the request, but identity verification does not decide whether the arrangement is contractually or legally valid.

Correct and retain evidence safely

Do not erase a mistaken entry. Add a correction that preserves the original value, identifies the editor, records the correction time, and points to the supporting evidence.

The general operations queue can show a case ID, owner, state, and next action while banking documents remain in a restricted system. Before delegating the work, use the virtual assistant access checklist to define permissions and revocation steps.

The business and its qualified advisers set retention rules. A coordinator follows the approved schedule and records a safe evidence reference rather than choosing how long financial or identity records should remain.

Review a closed case

Sample closed cases against original evidence. Confirm that the callback route came from a trusted baseline, the log names the verifier and approver, the outcome matches the protected source, and the vendor master update points back to the approved case.

Test exceptions as well as clean completions. Include a denied request, an unanswered callback, a disputed contact, and a corrected entry. If they all appear as routine completions, the status design is hiding material differences.

NIST SP 800-53 Rev. 5 provides a catalog of security and privacy controls that organizations can tailor as part of their risk-management process. That framework supports a written control boundary for sensitive vendor changes, but the log fields and approval sequence here are operational recommendations rather than NIST requirements.

Frequently asked questions

Should the log contain the new bank account number?

No. Store bank details in the approved protected system and use a restricted record identifier in the verification log.

Can the requester provide the callback number?

The request may contain a number, but the verifier should retrieve the independent contact method from an approved source that predates the request.

What happens when the vendor contact cannot be reached?

Record the permitted attempts and leave the case pending. Follow the written escalation or expiry rule, and do not approve a change merely because a payment is due.

Can a virtual assistant manage the process?

A virtual assistant can maintain the log and follow an approved verification script. An authorized internal owner retains approvals, exceptions, protected system access, and payment release decisions.
