Vendor bank-detail change requests: verifying safely in accounts payable
For accounts payable clerks, bookkeepers and office managers who receive and process requests to change a supplier's bank details. Prerequisite: the course on supplier setup and bank-detail change control, which introduces business email compromise and the call-back rule. This course goes into the procedure step by step: logging and holding every request whatever the channel, choosing a call-back number that is truly independent, running the call so the supplier gives the details, dual approval and a change log a reviewer can check, first-payment checks, and what to do in the first hour if money may have gone to a fraudster. Practice items are written as a simulated AP inbox. Reporting routes are given for the US (FBI IC3) and the UK (Take Five, NCSC) as examples; your company's procedure and your bank's instructions come first. This is not legal advice.
