Treat the change request, independent contact source, callback record, approval, supplier master-data update and encrypted evidence pack as separate controls. Never verify a bank change by replying to the request or calling a number supplied inside it.
01 / DECISIONProtect the supplier bank-change without hiding ownership
Supplier change history can support accountability, but indefinite retention expands exposure and confusion. Tie retention to payment release, post-payment release review, contractual duties, litigation holds and accounts-payable evidence needs. Distinguish deleting an archive entry from verified sanitization of every underlying device and backup.
An accounts payable reviewer freezes a pre-payment verification case for approver review. The team first proves the workflow with fictional supplier-change records, documents each authorized role and preserves the working source separately.
Run the control sequence
- 01
Classify artifacts by decision, legal and operational value.
- 02
Assign review dates tied to payment release and periodic supplier-change reviews.
- 03
Check holds, contracts and records obligations before disposal.
- 04
Retire superseded access and document archive disposition.
- 05
Use approved media sanitization for storage that truly must be cleared.
Preserve decision evidence
Record class, verification case, retention basis, owner, review date, hold status, access removal, archive action, media action, approver and completion evidence.
Stop when
- Retention is “forever” without a stated reason.
- A hold or contractual duty has not been checked.
- Vault deletion is described as guaranteed device sanitization.
The record should show the approved verification case, tested environment, responsible people and known limitations without storing passwords or unnecessary supplier bank-change content.
Separate the surrounding controls
Does not replace supplier identity checks, bank ownership proof, payment authorization, guaranteed backup or password recovery. Encryption does not verify supplier identity, prove bank-account ownership, preserve every backup or remove plaintext working copies automatically.
Supplier verification archive questions
Should the encrypted archive become the live supplier record?
No. Keep the supplier master-data record and payment authorization in approved systems; archive only the evidence needed to support the decision.
Does resetting a password recover an existing archive?
Do not assume so. Document the product-specific recovery boundary and test a separate recovery copy.
