A fake invoice or a change to payment details

How criminals trick businesses into paying the wrong account.

Updated September 21, 2026

One of the costliest scams against small businesses is a message that looks like it is from a supplier, saying their bank details have changed. The next payment goes to a criminal.

Red flags

  • A new bank account, routing number or payment address.
  • An urgent request to pay today.
  • An email address that is close to the real one, but not identical.
  • A sender who cannot talk by phone.

How to check

  1. Pause before paying.
  2. Call the supplier on a phone number you already have, not one from the message.
  3. Ask them to confirm the change out loud.
  4. Have a second person at your business approve any change to payment details.
