Prevent Overbilling
Prevent Overbilling
Overbilling is the practice of charging more than contractually owed—inflated quantities, padded hours, duplicate line items, or “accidental” extras. It may be criminal or simply opportunistic, but the effect is the same: excess outflow.
How Vantirs detects this attack type
Vantirs compares current invoice lines and totals to each vendor’s historical distribution of amounts and frequencies. Statistical outliers and repeated spikes trigger review so overbilling does not become normalized.
Prevention checklist
Use this list alongside Vantirs to tighten controls and make reviews consistent across clients and bookkeepers.
- ✓ Anchor invoices to contracts and rate cards.
- ✓ Require manager sign-off on variances above a threshold.
- ✓ Perform periodic vendor statement reconciliations.
- ✓ Track cumulative spend against budgets by vendor and category.
- ✓ Investigate vendors with frequent “corrected” or replacement invoices.
