Carrier overbilling is the most documented forensic-audit pattern in the modern supply chain. We know what to look for, and we know how to prove it.
Section 1
Carrier invoices are dense, formatted to per-carrier conventions, and arrive at high volume — a single mid-size shipper can process tens of thousands of freight invoices a quarter. The volume alone obscures the patterns. A 2% overbilling rate distributed across 30,000 invoices a year is recoverable capital that gets written off as “the cost of doing business” because the audit cost exceeds the per-invoice variance.
Forensic audit is the answer to that volume problem. Mechanised pipelines read every invoice. Deterministic engines validate every charge against the contracted rate sheet, the actual shipment manifest, the dimensional weight derivation, and the accessorial fee schedule. The patterns that hide at scale surface at audit.
Section 2
Carriers sometimes invoice at a higher freight class than the actual commodity warrants.
How LEGERIS catches itLEGERIS cross-references the commodity description on the bill of lading against the National Motor Freight Classification and flags any class upcharge.
Dim-weight calculations are formula-driven but error-prone.
How LEGERIS catches itLEGERIS recomputes dim-weight from the package dimensions on the manifest and compares to the carrier's billed weight.
Detention is invoiced when a carrier waits beyond a contracted free-time window. Free-time calculations vary by carrier, lane, and equipment type.
How LEGERIS catches itLEGERIS reconstructs the wait time from the timestamps and validates the charge against the contracted free-time matrix.
Fuel surcharges, residential delivery fees, liftgate fees, inside-delivery fees — each has a contracted basis that the invoice should honour.
How LEGERIS catches itLEGERIS validates every accessorial line against the rate sheet.
When the same shipment is invoiced twice (once per leg, once consolidated, once corrected, once final), the duplicate can survive review at volume.
How LEGERIS catches itLEGERIS cross-references manifest IDs against historical invoice fingerprints.
Section 3
Each carrier invoice is extracted into a structured schema — the line items, the accessorial charges, the dim-weight derivation, the lane, the equipment type, the timestamps. The structured invoice is then cross-validated against the contracted rate sheet (ingested as the rulebook), the original bill of lading (where available), and the historical invoice fingerprint database (to catch duplicates). Every finding ships with its evidence — the contracted rate, the invoiced rate, the calculation, the source line on the invoice. The report is forward-ready to the carrier’s billing team.
