Ring before you pay: a free card for your accounts desk

A free card for whoever pays the bills in your business. Print it, pin it up next to the computer, and it does one job: stops a fake invoice getting paid.

False billing was the scam Australian small businesses reported most in 2025. It usually looks like a polite email from a supplier you know, saying their bank details have changed. The rule on this card stops it, and it costs nothing.

For the accounts desk

Bank details changed?
Ring first.
Then pay.

  1. Don't use any phone number or link in the email.
  2. Ring the supplier on a number you already have.
  3. Confirm the new details with them, then pay.

Already paid?

Ring your bank straight away and ask them to recall the payment. Then report it at cyber.gov.au.

Why ringing first works

The scam works because the email looks right: real logo, real signature, sometimes sent from the supplier's own hacked email account. What a scammer can't control is the phone number you already have on file. One short call to that number, before you pay, is the check that matters.

If the money has already gone, speed counts. Ring your bank first and ask them to try to recall the payment, then tell the real supplier, then report it through the Australian Cyber Security Centre at cyber.gov.au.
