A verification path for bank detail changes that uses an independent contact and a dated approval.
Why this control matters
A reliable vendor bank changes control starts with a stated purpose. Verify the change through a known contact and record approval, then compare the record with that purpose rather than the busiest queue.
What to check first
Start with one test: test the path against a request from a new email address. Keep the case that failed because a named mismatch is stronger evidence than a general complaint.
Build the routine
Put the vendor bank changes review on a short weekly calendar. Open the queue, run the test, and leave one decision for each item.
Handle the exceptions
Log the exception when you see a bank change with matching letterhead but a new domain. Record why the normal rule missed it and where the fix belongs.
Review the evidence
Save the smallest useful evidence: the request, callback, and approval. A dated record lets the next reviewer continue without asking you to remember.
What to change next
Finish with one controlled change. Use the evidence to add one verification step for high-value vendors, then set the next review date.
