Invoice fraud is one of the most effective scams targeting businesses, with Australian companies losing over $16.2 million in 2023 alone. Scammers manipulate invoices by altering payment details or sending entirely fake payment requests, redirecting funds to their accounts. These schemes can be difficult to spot, and without vigilance, your business could be next.
In this guide, we’ll explain how invoice fraud works, the warning signs to watch for, and the steps you can take to protect your business from falling victim to this costly scam.
Invoice fraud occurs when scammers send fake or altered invoices, tricking businesses into making incorrect payments.
Warning signs include mismatched details, unexpected invoices, and urgent payment requests.
Protect your business by verifying payment details, training staff, using secure systems, and maintaining vigilance.
Invoices are a crucial part of business operations, ensuring payments are processed accurately and securely. However, as businesses increasingly move their payment processes online, scammers are seizing opportunities to exploit vulnerabilities. Invoice fraud is one such scam, where fraudsters manipulate or forge invoices, redirecting funds to their own accounts.
In 2023 alone, Australian businesses lost over $16.2 million to payment redirection scams, many of which involved fraudulent invoices. At pay.com.au, we are committed to making payments secure and seamless, and part of that commitment is helping you protect your business from fraud.
Invoice fraud is a type of payment redirection scam. Scammers typically impersonate legitimate suppliers by altering payment details on invoices. The following are common methods used in these scams:
Compromised email accounts
Scammers access a business’s email system through phishing links or malware, intercepting invoices as they are sent. They modify the payment details and forward the altered invoice, tricking the recipient into sending funds to the scammer’s account.
Fake invoices from impersonated businesses
Cybercriminals often impersonate well-known suppliers, sending invoices for products or services that were never ordered. These invoices might claim overdue payments or subscription renewals for services you’ve never used.
Overcharging and hidden fees
Some scammers inflate invoice amounts or introduce hidden fees, hoping businesses will overlook discrepancies. If you don’t carefully compare invoices to original agreements, you might unknowingly pay fraudulent charges.
Scammers are always evolving their techniques, but these are key red flags to be aware of:
Email discrepancies
The sender’s email address closely resembles a trusted business, but with minor alterations.
Unexpected invoices
You receive a bill for products or services you never ordered.
Bank Details change
A supplier unexpectedly asks for payments to be made to a new bank account.
Urgency and threats
The email demands immediate payment or threatens legal consequences if payment is not made.
Suspicious attachments or links
The email encourages you to open an attachment or click a link to complete the payment.
Taking proactive steps can significantly reduce your risk of falling victim to invoice fraud. Here’s how:
Verify payment detail change requests
Always confirm any changes to payment details directly with the supplier. Use a trusted contact method, such as a phone number you have on file, not one listed on the email or invoice.
Train your team to spot scams
Educate your team on invoice fraud tactics and encourage them to verify payment details before processing any transactions. Consider implementing a policy that requires multiple levels of approval for large payments.
Regularly update software and security measures
Keep all business systems, including email and accounting software, up to date. Implementing strong cybersecurity measures can help prevent phishing attacks and unauthorised access.
Review invoices carefully
Always compare new invoices with previous ones. Look for discrepancies in amounts, payment details, or formatting. If anything seems unusual, verify with the sender.
