Freight Invoice Overcharge Estimator
Freight-audit advisory firm Tompkins Ventures estimates that companies typically recover 3–10% of their total annual freight and parcel spend through professional audit — based on a finding that 5–10% of freight invoices carry some kind of billing error (Jim Tompkins, Tompkins Ventures, July 2026). This free estimator applies that benchmark range to your spend to show a rough potential recovery. It is NOT an audit and cannot replicate what a professional carrier-rate review of your actual invoices would find. Use it to size the opportunity, then get a real audit.
Primary source: Jim Tompkins, Tompkins Ventures, “Why Freight and Parcel Shipping Require Post-Auditing” (July 7, 2026) — the 3–10% recovery band and 5–10% error-incidence figure on this page are read directly from that commentary.

Which freight modes do you use?
Selecting modes changes only the error-type checklist shown below — the 3–10% recovery band is applied uniformly across all modes.3–10% range: Jim Tompkins, Tompkins Ventures, July 2026. This is a benchmark estimate, not an audit — actual recovery varies by carrier agreements, accessorial schedules, and invoice history, and comes only from a line-by-line review of your carrier bills.
Read before relying on this estimate
- This is an industry-benchmark estimate, NOT an audit of your actual invoices or carrier contracts. Your real recovery depends on your specific carrier agreements, accessorial schedules, and invoice history.
- The 3–10% recovery range is an industry average from a named advisory firm. Your actual recovery may be higher or lower, and no mode-specific split exists — the same band is applied to every mode.
- Carrier dispute windows vary — most parcel carriers accept billing disputes within roughly 180 days of the invoice date. Older claims may not be recoverable depending on your carrier contract language.
- Historical backlog estimates are approximate. The 60% per-year efficiency factor is a conservative internal assumption, not a measured statistic, and backlog is capped at 4 additional years.
Freight Audit FAQ
What percentage of freight invoices actually have errors?
Freight-audit advisory firm Tompkins Ventures estimates that 5–10% of freight and parcel invoices carry some kind of billing error, with cases running as high as 40% in some shipping programs (Jim Tompkins, Tompkins Ventures, July 2026). This is an experience-based industry estimate from a named practitioner, not a controlled study. The most common errors include dimensional-weight re-measurement rebills on parcel shipments, duplicate invoices submitted under different invoice numbers, split invoicing (one shipment billed across multiple invoices), unclaimed service-failure refunds (late deliveries that qualify for the carrier's own guarantee but are never claimed), and wrong accessorial charges or fuel-surcharge miscalculations. Note that error incidence (share of invoices with an error) is a different figure from the 3–10% recovery band (share of dollars recovered).
How much of my freight spend can I realistically recover?
The same Tompkins Ventures estimate puts the typical recovery at 3–10% of total annual freight and parcel spend. The range depends on how long invoices have gone unaudited, how complex your accessorial and rate structures are, and whether you have a Transportation Management System (TMS) enforcing rates — shippers without TMS enforcement tend to sit at the higher end of the range. This estimator applies the full 3–10% band across all modes (there is no primary source for mode-specific recovery rates) and credits each additional year of unaudited backlog at a conservative 60% efficiency factor, capped at 4 extra years.
What are the most common freight billing errors?
Based on Tompkins Ventures (July 2026): (1) Dimensional-weight / re-measurement rebills — parcel carriers re-scan package dimensions after pickup and resubmit a higher charge; (2) Duplicate billing — the carrier resubmits the same shipment under a new invoice number, or both the carrier and freight broker bill the same load; (3) Split invoicing — one shipment billed across two or three invoices so each individual line passes a spot-check; (4) Unclaimed service-failure refunds — late or missed-delivery guarantee credits that the carrier owes but never issues unless claimed; (5) Wrong accessorials — charges for residential delivery, address corrections, or fuel surcharges that were either not applicable or calculated incorrectly against the contracted rate. The estimator tailors this checklist to the modes you select (parcel, LTL, FTL, ocean, air).
Does GingerControl audit my freight invoices directly?
Yes — GingerControl audits 100% of freight invoices against your contracted carrier rates and accessorial schedules across parcel, LTL, FTL, ocean, and air. Unlike traditional freight auditors, GingerControl also audits the duty and tariff layer: HTS classification review, Section 301/232 exposure checks, and tariff surcharge validation against the duty actually owed. That combined audit is what drives the total landed-cost reduction in our recovery engagements.
How far back can a freight audit recover overcharges?
A professional audit typically covers the most recent 12 months as its initial scope. Most parcel carriers (UPS, FedEx, DHL) accept billing disputes within roughly 180 days of the original invoice date for common error types; some dispute categories have shorter or longer windows depending on carrier contract language. LTL and TL overcharge claims may have different lookback terms. For a historical backlog review beyond 12 months, the recoverable amount per year decreases because dispute windows close. This estimator applies a conservative 60% efficiency factor for each additional year, capped at 4 years back.
How does freight audit differ from duty drawback?
Freight audit recovers money from carrier billing errors — your carrier billed you incorrectly and owes you a credit. Duty drawback is a US customs program (19 U.S.C. §1313) that recovers customs duties you paid on goods that are later re-exported, used in manufacturing exports, or destroyed as non-conforming. They are entirely separate programs with different processes, timelines, and qualification rules. GingerControl offers both: freight audit as part of the freight-audit service, and drawback scoping through our customs-compliance advisory work (filing itself is handled with a licensed drawback broker partner).
