Carrier and port invoice audit for terminals

Last reviewed:

Outturn's Carrier Invoice Audit worker recomputes rail freight and port-due invoices from the published tariff and your own records, and flags every line that does not match. The carrier's scale and the port's system are not the only truth: your own records are evidence too.

The problem in one sentence

Rail carriers and port authorities bill from their own systems; unless someone recomputes the invoice from the terminal's own records, an overcharge is simply paid.

What the worker checks

CheckWhat it recomputesSource of the rule
RAIL-06 Freight-mass billingBillable mass per wagon: the mass rounded to the full tonne (500 kg or more rounds up, less than 500 kg is dropped), minimum 45 t unless the tariff says otherwise; compared with the tonnes on the freight invoice lineLTG Cargo tariff book, effective 2026-06-30
BIL-06 Port infrastructure chargeVessel fee, wharf fee and tonnage fee for a ship call from its gross tonnage; compared with the invoiced port-due linesLTSA Order 2BE-95, in force from 2026-07-01

Time-based carrier charges (wagon hours, storage organisation) are recomputed by the Demurrage & Detention worker, and the LTG wagon-use statement has its own page: rail statement audit.

Coverage today: two tariffs (LTG Cargo freight mass and the Klaipėda port infrastructure charge). Other carriers and ports need their tariff added as a versioned, sourced rule before the check can run. Outturn never assumes a tariff.

Example finding

Example — synthetic data, invented for illustration. Not a customer result.

Wagon 59214101 (synthetic number), waybill mass 61.2 t. Under the tariff rule the billable mass is 61 t (the 200 kg remainder is below 500 kg and is dropped). The freight invoice line bills 63 t at the invoice's own rate of €20.00/t (rate invented for this example).

Difference: 2 t × €20.00 = €40.00 on one wagon. The finding links the waybill row, the invoice line and the tariff clause. A second example wagon with a waybill mass of 38.7 t is correctly billed at the 45 t minimum: no finding.

Data you need

  • RAIL-06: a wagon list with waybill mass (for example the carrier's wagon export) and the freight invoice lines, with the wagon number in a reference column.
  • BIL-06: a ship-call export with gross tonnage and the port-due invoice lines that reference the call.
  • Excel or CSV is enough. See how Outturn connects to your systems.

How fast you can start

Upload one month of wagon data and the matching freight invoice in the free trial. The first check run starts when the import is confirmed.

Honest limits

  • Outturn does not dispute invoices on your behalf. It prepares the evidence; a person decides and sends.
  • Only tariffs that exist as published, versioned rules are recomputed.
  • A difference is a review item: a contract can override a tariff, and Outturn shows which rule it used so you can check.
  • The BIL-06 recompute covers the vessel, wharf and tonnage fees; other components of the port infrastructure charge are not modelled.

Frequently asked questions

What does the Carrier Invoice Audit worker recompute today?
Two invoice types: rail freight billed by mass under the LTG Cargo tariff book (wagon mass rounded to the full tonne, 500 kg or more up and less than 500 kg dropped, minimum 45 t per wagon; check RAIL-06) and the Klaipėda port infrastructure charge for a ship call (vessel, wharf and tonnage fees; check BIL-06). Wagon-hour charges are recomputed by the Demurrage & Detention worker.
Can it audit other carriers and ports?
Only after that carrier's or port's tariff has been added as a versioned rule with its source. Until then Outturn does not guess. Tell us which tariffs you pay and we will say honestly whether and when they can be covered.
Is this freight audit and payment (FAP) software?
No. Outturn does not pay invoices or replace a freight-payment process. It recomputes selected third-party charges from your own operational records and the published tariff and shows the difference with evidence.
What happens when an overcharge is found?
The case goes to Commercial or Finance with the waybill row, the invoice line and the tariff clause attached. A person decides whether to dispute it. After the carrier's credit note is imported, the next check run confirms the difference is gone.
