ParcelProof — carrier invoice DIM-weight & surcharge audit

Paste the shipment records you handed over and the carrier's invoice lines. Every line is recomputed against the tariff in force on its own ship date, the accessorial eligibility is re-checked with the trigger that failed, and the recovery is priced from your own contract rate card — a line that cannot be priced is reported unverifiable, never guessed.

1 · Your two files

Paste or upload the shipment records you handed over and the carrier's invoice lines. The audit runs in this page — the same deterministic engine the agent tools call.

The examples are synthetic worked cases (the same fixtures the build gate asserts against). Your own files are audited in the browser: no upload, no LLM, no third-party call.
