Shipping Carrier Rate Reconciliation

Detects shipping rate variances by reconciling carrier invoices against Bill of Lading weight and accessorial charges, flagging overbilling patterns automatically.

#Logistics#Billing#Variance#Audit

The Problem

Major shipping carriers systematically overbill by hiding surcharges, inflating dimensional weights, and applying duplicate fees. Monthly audits catch 3-8% billing variance, but manual reconciliation of 5,000+ invoices against Bills of Lading is operationally impossible, leaving companies to absorb hundreds of thousands in overages yearly. FedEx and UPS deliberately obscure charge structures to make discovery hard; systematic overbilling detection is the only path to refund recovery and carrier leverage in contract renegotiations.
