Prevent Bank Change Fraud

Prevent Bank Change Fraud

Bank change fraud is the class of schemes where an attacker convinces AP to send future payments to a fraudulent account—often by email claiming an “updated” wire or ACH destination. It is one of the highest-loss vectors for mid-market finance teams.

How Vantirs detects this attack type

Vantirs compares requested bank and routing details against each vendor’s historical payment footprint in QuickBooks Online. A change from established beneficiaries triggers review, with context so approvers can validate out-of-band before funds move.

Prevention checklist

Use this list alongside Vantirs to tighten controls and make reviews consistent across clients and bookkeepers.

  • Never accept bank changes from email alone; call the vendor on a known number.
  • Maintain a vendor master with validated banking info and change procedures.
  • Use positive pay or ACH blocks where your bank supports them.
  • Document who approved each change and when.
  • Alert the team when a “change” coincides with a new email domain.

Stop bank change fraud before payment leaves QuickBooks

Vantirs fingerprints vendors and flags mismatches so your team approves payments with confidence—without slowing down legitimate work.
