Why line level
Spot-checks miss what a line-level audit catches
Spot-checks
- Only a sample of invoices is reviewed
- Duplicate bills and fuel surcharge errors go unnoticed
- Late delivery and service failure refunds are missed
- Damage and loss claims are left untracked
Line-level audit
- Every rate, weight and accessorial checked against your contract
- Duplicate invoices and fuel surcharges checked on every invoice
- Refunds for late deliveries and service failures claimed
- Damage and loss claims filed and tracked to status
