Catch shipping overcharges by having an AI agent check every invoice against your contract

Quick answer

Rebel Cheese, a lean vegan cheese maker in Austin, Texas that ships orders, estimated it was overcharged $250,000 by shipping partners after a holiday rush. An AI agent now checks weekly invoices line by line against the contract and checks box photos for bulging that triggers fees. Fortune reports $400,000 saved in a year.

Business type: Online stores. Tool used: AI agent (invoice and contract audit). Result: About $400,000 saved in one year, Fortune reports. Monthly savings recently dipped below $40,000, which the CEO thinks is because carriers now know the AI is checking.

How they set it up

  1. Each week, upload your shipping invoices and your contract rates (zones, weights, sizes).
  2. Have the agent flag every charge that doesn't match the contract, with proof.
  3. Use that proof to dispute the charges and get credits.
  4. Have it check box photos, sizes and weights before shipping, since a bulge of as little as an eighth of an inch can trigger extra fees.

Result

About $400,000 saved in one year, Fortune reports. Monthly savings recently dipped below $40,000, which the CEO thinks is because carriers now know the AI is checking. (as reported by the source)
