Ingest the carrier's EDI 210 Motor Carrier Freight Details and Invoice transaction, parsing all charge segments including base freight, fuel surcharge, and accessorials
Re-rate the shipment using the original tender parameters (origin, destination, weight, class, accessorials) against the agreed carrier tariff or contract rate via the SMC3 RateWare XL API
Compare the invoiced total to the re-rated total within an acceptable tolerance (typically ±$1 or ±0.5%); auto-approve within tolerance and flag discrepancies above threshold
For flagged invoices, identify the charge component causing the discrepancy (weight, class, zone, accessorial code) and generate a dispute reason code
Transmit EDI 812 Credit/Debit Adjustment or a carrier-portal dispute to the carrier with supporting documentation for short-payment approval
Known gotchas
Carrier invoices often include minimum charge provisions that override the rated amount; ensure your re-rating logic applies the carrier's minimum charge rule
Fuel surcharge indices change weekly for most LTL carriers; re-rating must use the fuel surcharge percentage in effect on the shipment date, not the invoice date
Weight discrepancies from carrier reweigh are legitimate if the carrier can provide a certified scale ticket; dispute only when no reweigh documentation is provided
