Vendor bank-change verification checklist
[ ] 1. Do NOT use any phone number, link or contact in the change request.
[ ] 2. Call the vendor at a number already in your records (old invoice, contract, vendor file).
[ ] 3. Ask your known contact to confirm the change and the last 4 digits of the new account.
[ ] 4. Check the request: urgency, new email domain (lookalike letters), changed signature, new country or bank.
[ ] 5. Second person approves the change before it's entered (dual control).
[ ] 6. Record: date, who called, number used, who confirmed, who approved.
[ ] 7. Hold the next payment until steps 2-6 are done.
[ ] 8. After the first payment to the new account, confirm with the vendor it arrived.
