What is vendor impersonation fraud?

ERP and accounts-payable controls verify that the invoice is expected, matched and approved — and in this fraud, it is. The goods were delivered; the amount is right; the approver approves. The only falsified element is the destination account, which sits in the vendor master record that was updated last week by a convincing email. Segregation of duties never sees it.

Manual call-back verification of every bank-detail change works when it actually happens — practice decays under AP workload. Continuous vendor verification automates it: Trustmi validates vendor identity and monitors detail changes across the payment flow, correlating them with email and behavioral signals, so a redirected payment is stopped before execution rather than discovered at reconciliation.
