Drop in a CSV export of your carrier invoices and get an instant screen for the overcharges that hide in freight billing — duplicate invoices, inflated fuel surcharges, out-of-band accessorials, reclassification risk, and billing math errors.
Your data never leaves this page. Every invoice is parsed locally, in your own browser. This tool makes no network connection with your file — there is nothing to upload, store, or breach.

This screen flags anomalies visible in your invoice data alone. A full Hawthorne audit cross-checks your contracted rates, carrier-specific tariff rules, and accessorial agreements — where the bigger recoveries live. We typically work on contingency, so a review costs you nothing up front.
