IBAN checks on invoices: spotting invoice fraud

Why a changed IBAN on an invoice is a red flag, how invoice fraud works and how automatic IBAN checks and alerts help prevent it.

Sebastian de Goeij 6 min read Updated

Short answer

In invoice fraud a business receives a real or fake invoice with a different account number, so the payment goes to the fraudster. An IBAN check compares the account on the invoice with what is known for the supplier and flags deviations. Autoboeker checks IBANs during processing and flags unknown suppliers, high amounts and unusual behaviour.

Key takeaways

  • A new IBAN for a known supplier is always a signal.
  • Verify changes through a known channel.
  • Combine with checks on unknown suppliers and high amounts.
  • Approval on large amounts adds a control point.
