An altered invoice scam can be difficult to recognise. Read on to learn more about this type of scam and how to keep yourself safe.

What are altered invoice scams?

This is a tricky one, as it's usually an invoice or request for payment that you were expecting and the invoice appears to come from the business that it’s supposed to. The only visible difference is the bank account number on the invoice that has been altered or a follow up email is sent with a request to change the account number.

Scammers may access a business’ email account, they’ll read the emails for a couple of weeks to see when large payments are due. The scammer then sends an email from the business’ email address asking the customer to pay into a different bank account as they have recently changed banks.

Tips to avoid altered invoice scams

  • Call the business that sent the invoice on their official phone number. Use the number saved in your phone or on their official site (not the number listed on the invoice) to check that it is a legitimate invoice and that the bank account number on the invoice is correct.
  • Always confirm if goods or services have been requested and received by others in your business or household before paying an invoice.
  • Limit the number of people in your business who are authorised to make orders or pay invoices.
  • Immediately cut contact with the scammers.
