Connect one account or your entire supply chain. Our proprietary engine cross-examines every manifest line item 24 hours a day.
Amazon fulfills billions of items, but loses and damages warehouse stock daily. We reconcile your 18-month ledger to extract every single penny owed.
Carriers rely on automated sorting lasers and complex surcharge grids that routinely overbill shippers. We audit every invoice before payments clear.
Packages lost or stalled in carrier transit represent pure lost profit. We auto-detect stuck packages and submit carrier insurance claims instantly.
Based on industry benchmarks across millions of shipments, businesses leak 1.5% to 3% to carrier errors and unclaimed reimbursements.

Link your Amazon Seller Central, FedEx, or UPS billing account using secure, restricted read-only API tokens. We never ask for withdrawal permissions or bank passwords.

Approved credits and refunds deposit directly to your carrier billing account or Amazon balance. We simply invoice our 25% contingency fee afterward.
If we don't recover money for your business, you owe us nothing. You keep 75% of every dollar we claw back from carriers and marketplaces.
