Prevent Duplicate Invoice Fraud
Prevent Duplicate Invoice Fraud
Duplicate invoice fraud occurs when the same expense is submitted twice—intentionally or through sloppy controls—so the organization pays twice for one good or service. Fraudsters may reuse invoice numbers with small tweaks or submit near-copies across different approvers.
How Vantirs detects this attack type
Vantirs analyzes invoice attributes and payment history to surface duplicates and near-duplicates: similar amounts, vendors, dates, or references that suggest the same underlying obligation. That gives AP a second line of defense beyond manual spot-checks.
Prevention checklist
Use this list alongside Vantirs to tighten controls and make reviews consistent across clients and bookkeepers.
- ✓ Implement three-way match (PO, receipt, invoice) for material spend.
- ✓ Use sequential controls so duplicate invoice numbers or amounts trigger review.
- ✓ Centralize invoice intake so the same bill cannot be routed through two paths.
- ✓ Reconcile paid invoices periodically against vendor statements.
- ✓ Train staff to escalate “urgent” re-sends of the same invoice.
