Automate supplier bank detail change checks
Requests to change bank details are a common route for payment fraud. Modern spots them in your inbox, checks for warning signs and holds the change until a person has verified it with the supplier on a known number.

The instruction
“When any email to ap@ asks to change supplier bank details, do not update anything. Check the sender domain against the supplier record, and look for lookalike domains, urgent language and other changes in the last 90 days. Post the request to #ap-security in Slack with a risk rating and the phone number we have on file. Only update the details after the AP lead confirms they called the supplier and the change is genuine.”

No. Every change is held until a person confirms they have verified it with the supplier using contact details already on file.
Lookalike sender domains, changed reply-to addresses, urgent language, recent changes for the same supplier and requests that arrive just before a payment run.
Once verified, Modern updates the supplier record in Xero, QuickBooks, NetSuite or Sage, and notes who approved it.
