Spotting scams

Invoice scams

What is an invoice scam?

Invoice (also known as mandate scams) is when a fraudster will pretend to be a solicitor, tradesperson or someone from a trusted organisation and intercept emails or hack into an organisation's email and pretend to be them. They'll inform you that you need to pay them into a new or amended bank account, which they now have ownership over.

Tips on how to spot an invoice scam

  • You receive new bank details from an existing service provider (such as a builder, solicitor or other tradesperson) that are different to the account details you hold.
  • You receive duplicate or more frequent invoices for a product or service than the genuine service provider usually sends.

Steps to protect yourself

  1. 01

    If you're unsure, call the company or the person providing the service on a trusted number so that they can confirm the account details that you’ve received are correct.

  2. 02

    When making your first payment, transfer a small amount first and then check with the company that the payment has been received.

  3. 03

    Send confirmation of payment to the company or person providing the service once their invoice has been paid.

  4. 04

    If there's a change in bank details, always query this as companies rarely change their bank details.       

  5. 05

    Be careful of the information you choose to share on social media, as criminals will use this (such as a home renovation) to target you.
