What a freight invoice audit can screen
Structured invoice exports can surface repeat invoice/shipment/type/amount combinations, billed-versus-expected rate variances, accessorial charges without a supplied support reference, and reweigh candidates. A flag is a review candidate—not proof of an overcharge.
Start with the smallest useful export
For a first pass, useful fields include invoice ID, shipment or PRO ID, charge type, billed amount, expected or contract amount when available, and evidence references. Weight fields improve reweigh screening.
Why evidence comes before recovery
A duplicate-looking row can be legitimate. A rate variance can reflect an approved change. The output should therefore preserve source-row evidence and route candidates to human review before any claim, dispute, or accounting action.
