🚚 Freight Invoice Rate-Card Auditor

Freight Invoice Rate-Card Auditor applies supplied flat, per-unit, and percent-of-linehaul rules by charge code, shipment date, and quantity range. It flags missing or ambiguous rules, rate variance, duplicate-looking charges, unknown shipments, and unsupported accessorials, then returns an audit ledger, findings, JSON payment-review gate, and memo. It never interprets tariffs, sends disputes, or recovers funds.

What it produces

• Invoice-line audit ledger with applied rule and variance
• Rate and accessorial findings CSV
• JSON owner-payment gate
• Freight-review memo tied to supplied evidence

Use cases

• Check carrier invoices against supplied rate cards
• Catch linehaul, fuel, and per-unit rate variance
• Block unsupported detention and other accessorials
• Surface missing, expired, or ambiguous rules before payment

Known limitations

• Version 1 applies only the explicit normalized rules supplied by the user and does not interpret complex tariffs.
• Zones, reweighs, class changes, minimums, and carrier-specific exceptions require explicit modeled rules or owner review.
• A ready result does not direct payment or establish a valid dispute.
