Your freight invoices are
bleeding money. We find it.

Fuel surcharges above the FSC index, broker margins beyond your agreement, undocumented detention charges, and accessorial fees you never authorized quietly drain your per-load profit. ShieldEngine™ audits every freight invoice line item against your rate confirmation and flags every overcharge — with the documentation to recover it.

The Problem

What you're dealing with every day

The billing fraud and overcharge patterns that cost your clients money — and your practice time.

Fuel surcharge overcharges

Brokers and carriers frequently apply fuel surcharges above the DOE or DAT FSC index rate specified in your rate confirmation — adding hundreds of dollars per load that you're not contractually obligated to pay.

Broker margin above agreed rate

Spot market brokers routinely take margins beyond what's disclosed in your agreement. ShieldEngine™ cross-references the rate confirmation against the invoice and flags every discrepancy.

Undocumented detention charges

Detention fees require documented proof of wait time. Many carriers bill detention without timestamps, gate logs, or BOL signatures — all of which are required to make the charge stick.

Unauthorized accessorial fees

Liftgate, inside delivery, re-delivery, and residential surcharges added to your invoice without appearing on the original rate confirmation are disputable in full.

Duplicate and phantom charges

Billing errors — duplicate line items, charges for services not rendered, and incorrect weight classifications — appear in roughly 1 in 5 freight invoices and are routinely caught by ShieldEngine™.

Rate confirmation vs. invoice gaps

The rate you agreed to and the rate on the invoice are often different. ShieldEngine™ compares both documents and flags every discrepancy with the exact clause from your rate confirmation.
