Freight Invoice Audit —
Stop Overpaying
on Every Shipment
Up to 6% of all freight invoices contain billing errors. For businesses spending $500,000 per year on freight, that’s $30,000 in recoverable overcharges — silently draining your margins on every load, every lane, every carrier.
Freight Billing Errors
Are Systematic —
Not Accidental
Freight invoices are among the most complex documents in business. LTL shipments involve freight class codes, NMFC numbers, accessorial fees, fuel surcharge indexes, density calculations, and multiple tariff schedules — any of which can be applied incorrectly. Carriers process thousands of bills per day and errors are inevitable.
But carriers don’t fix their own mistakes. Freight classification errors, duplicate billings, incorrect weight assessments, and phantom accessorial charges accumulate invoice after invoice — and without an active audit process, they remain buried in your accounts payable forever.
“The American Transportation Research Institute estimates that freight billing errors cost U.S. businesses billions of dollars annually — with the majority of errors never identified or recovered.”
The complexity of freight billing is precisely why most businesses can’t catch these errors internally. Our specialists and proprietary audit tools are purpose-built for this — validating every charge against your contracts, tariffs, and applicable rate schedules across every carrier and every mode.
The Billing Errors Costing
You the Most Money
Select a freight mode to see the specific billing errors we audit and recover for that category.
LTL Freight Invoice Auditing
LTL billing is the single most error-prone area in freight. With dozens of freight class codes, multiple accessorial fee categories, and carrier-specific tariff structures, the opportunities for billing errors — and for recovery — are greater than any other freight mode.
Freight Class Misclassification
The most common and costly LTL error. Incorrect NMFC classification results in higher freight rates — often 20–40% above what the correct class would charge.
🔴 High ImpactWeight Reweigh Overcharges
Carrier reweigh charges that exceed the actual shipment weight. We verify every reweigh against original shipping documentation and dispute discrepancies.
🔴 High ImpactPhantom Accessorial Fees
Liftgate, inside delivery, residential, and appointment fees billed when the service was not requested or performed.
🟡 Medium ImpactFuel Surcharge Rate Errors
Fuel surcharges calculated on the wrong base rate or using an incorrect surcharge table — often from the prior week’s index instead of the applicable shipment date.
🟡 Medium ImpactDuplicate Billing
The same LTL shipment billed more than once — common during carrier system migrations or billing cycle overlaps.
🔴 High Impact
FTL Truckload Invoice Auditing
Truckload billing errors are less frequent than LTL but often larger in dollar value per incident. Rate discrepancies, fuel surcharge miscalculations, and detention billing errors on high-value loads can represent significant recoverable amounts per shipment.
Rate Agreement Discrepancies
Billed rate doesn’t match the agreed rate in your load tender, spot quote, or contracted rate schedule.
🔴 High ImpactDetention & Layover Billing Errors
Detention charges billed without proper documentation of arrival/departure times, or layover fees applied outside contractual terms.
🟡 Medium ImpactFuel Surcharge Miscalculation
FSC calculated on the incorrect mileage, zone, or rate base — a consistent source of overcharges across high-mileage truckload lanes.
🟡 Medium ImpactMileage & Lane Errors
Incorrect mileage calculations on rate-per-mile loads, or shipments billed under the wrong lane or origin/destination pair.
🔴 High ImpactDuplicate Invoice Charges
FTL loads billed more than once — particularly common when shipments cross billing system boundaries or carrier subsidiaries.
🔴 High Impact
Ocean Freight Invoice Auditing
Ocean freight billing involves dozens of surcharges, port fees, carrier haulage charges, and documentation fees — all of which can be incorrectly applied, duplicated, or charged at the wrong rate. For importers and exporters moving significant volume, ocean freight audit recovery can be substantial.
Container Count & Type Errors
Incorrect container counts or wrong equipment type billed — particularly common in multi-stop ocean consignments.
🔴 High ImpactPort Surcharge Misapplication
Peak season surcharges (PSS), emergency bunker surcharges (EBS), and port congestion surcharges applied outside their effective dates or to ineligible trade lanes.
🟡 Medium ImpactDemurrage & Detention Overcharges
Demurrage and detention charges billed without accurate container tracking records, or calculated using incorrect free time allowances.
🔴 High ImpactDocumentation & Admin Fee Errors
Bill of lading fees, documentation fees, and carrier release charges billed at rates exceeding your service contract terms.
🟡 Medium ImpactDuplicate Freight Charges
Ocean freight charges appearing on both the carrier’s bill and a forwarding agent’s bill — resulting in double payment for the same service.
🔴 High Impact
Air Freight Invoice Auditing
Air freight is high-value and high-urgency — which makes billing errors especially costly. Chargeable weight miscalculations, incorrect AWB rates, and misapplied surcharges are endemic in air freight billing and represent recoverable amounts on virtually every significant shipment.
Chargeable Weight Errors
Air freight is billed on actual or volumetric weight (whichever is greater). Incorrect volumetric calculations or wrong chargeable weight applied to Air Waybills.
🔴 High ImpactSpecial Handling Fee Errors
Dangerous goods, temperature-controlled, and oversized cargo handling fees charged without the corresponding special handling being provided.
🟡 Medium ImpactFuel & Security Surcharge Miscalculation
Air freight fuel surcharges are published weekly and vary by origin country. Errors in applying the correct rate for the shipment date are common.
🟡 Medium ImpactCustoms & Clearance Overcharges
Import entry fees, customs examination fees, and clearance charges billed above the actual cost incurred or contracted rate.
🔴 High Impact
3PL Billing Audit
Third-party logistics providers consolidate many charges into a single invoice — making overcharges easy to miss. Storage, handling, pick-and-pack, receiving, and freight pass-through charges are all subject to billing errors, markup inconsistencies, and contract non-compliance that our auditors are specifically trained to identify.
Storage Fee Overcharges
Storage billed for locations or pallet positions not actually occupied, or monthly minimum charges applied incorrectly.
🔴 High ImpactPick, Pack & Labor Rate Errors
Labor activities billed at rates above your contract, or activities billed that were not performed or included in your base rate.
🟡 Medium ImpactFreight Markup Discrepancies
Carrier charges passed through to you at markups above the agreed 3PL margin, or third-party carrier invoices not reconciled against actual carrier charges.
🔴 High ImpactReceiving & Inbound Fee Errors
Inbound receiving fees charged per unit or pallet at rates inconsistent with your contract, or applied to shipments that qualified for included handling.
🟡 Medium ImpactMinimum Charge Non-Compliance
Monthly minimum charges applied even when actual activity should have exceeded the minimum, or minimums calculated on the wrong base metric.
🟡 Medium ImpactEvery Billing Error
We Audit and Recover
A comprehensive reference of every freight billing error type our auditors identify and file claims for on your behalf.
Freight Class Misclassification
Incorrect NMFC code applied to your freight — the single largest source of LTL overcharges. Often 20–40% above the correct rate for the commodity.
Weight & Dimension Errors
Carrier reweigh or re-measure charges that exceed documented weight/dimensions. We verify every discrepancy against original shipping records.
Duplicate Invoice Charges
The same shipment billed more than once across billing cycles, carrier systems, or sub-carriers. Our automation catches 100% of duplicates.
Phantom Accessorial Fees
Liftgate, inside delivery, residential, appointment, and notification fees billed when the service was not requested or performed.
Fuel Surcharge Errors
FSC calculated on the wrong base rate, index week, or surcharge table. Compounding across high-volume lanes creates significant recoverable amounts.
Rate Tariff Discrepancies
Billed rate doesn’t match the contracted or quoted rate in your load tender. Common after carrier rate changes are applied before contract expiry.
Demurrage & Detention Overcharges
D&D charges billed without accurate port or facility records, or free time calculated incorrectly under your service contract terms.
Port & Peak Surcharge Errors
PSS, EBS, GRI, and port congestion surcharges applied outside their effective date ranges or to trade lanes for which they don’t apply.
Mileage & Lane Errors
Incorrect mileage on per-mile loads, or lanes incorrectly mapped to higher-rate corridors. Often overlooked in high-frequency lane operations.
Storage & Handling Overcharges
Warehouse storage billed on incorrect pallet counts, or handling activities charged at above-contract rates or for work included in your base fee.
Documentation Fee Errors
BOL, AWB, customs documentation, and carrier release fees charged above contracted rates or for documents not provided.
Residential Surcharge Misapplication
Residential delivery fees applied to confirmed commercial addresses. One of the most consistently recoverable errors in LTL billing.

How Much Could
You Be Owed?
Recovery amounts vary by freight mode, carrier mix, and shipping volume. The table to the right shows typical error rates by mode — and what that means in dollar terms at different spend levels.
The most important factor is time. Freight billing dispute windows vary from 90 days (some carriers) to 2 years (Carmack Amendment claims for interstate freight). The longer errors go undetected, the more is permanently forfeited.
Example: $500K Annual Freight Spend
| Freight Mode | Typical Error Rate | Lookback Window | Complexity |
|---|---|---|---|
| LTL (Less-Than-Truckload) | 3–6% of spend | 18–24 months | High |
| FTL (Full Truckload) | 1–3% of spend | 12–18 months | Medium |
| Ocean Freight (FCL) | 2–4% of spend | 12 months | High |
| Ocean Freight (LCL) | 3–5% of spend | 12 months | High |
| Air Freight | 2–4% of spend | 6–12 months | Medium |
| Rail & Intermodal | 1–3% of spend | 12–18 months | Medium |
| 3PL Managed Freight | 4–8% of spend | 12–24 months | High |
| Intermodal Drayage | 2–5% of spend | 12 months | Medium |

From Businesses That
Recovered With DRS
“We had no idea our LTL carriers were systematically misclassifying our freight. DRS went back two years and recovered $143,000. The audit process was completely invisible to our operations — they just found the money and got it back.”
“After our carrier contract renewal, we assumed our new rates were being applied correctly. DRS found a 14-month gap where the old rates were still being charged on three of our busiest lanes. $87,000 back — money we never expected to see.”
“We spent 18 months paying demurrage charges we had no way to verify. DRS audited every container, identified the errors in the free time calculations, and recovered $62,000. They now monitor our ocean freight automatically every month.”
