We built this to audit our own account.
It found enough that we opened it up.
FeeBulldog did not start as a business. It started as a set of scripts for reconciling our own FBA account, because the numbers were not adding up and the existing services were charging 25% to tell us about a fraction of it.
We have sold physical products on Amazon for more than a decade. We have shipped the pallets, argued the denied claims, watched a mismeasured carton quietly eat the margin on a good SKU for months, and had a reimbursement service invoice us a quarter of a recovery we had already flagged ourselves. Every design decision here comes out of that.
The first month we ran it properly, it found $4,140 worth filing in a single account.
None of it was lost inventory. It was fourteen SKUs billed at the wrong size tier — one of them charged $9.39 per unit against a correct $5.66, across 305 units shipped in thirty days. Amazon had never physically measured that item. The dimensions on file were an estimate, and every order for months had been billed against the estimate.
Twenty SKUs showed the error. Six were estimates we could not verify against Amazon’s own measurement screen, so we dropped them rather than file on a guess — the $4,140 is what survived that cut. It includes a $1,137 error on one SKU, in one month, that no one would ever have sent an invoice for. It is also the number that turned a set of scripts into this.
One thing to be clear about: $4,140 is what we found worth filing, not what Amazon has paid. Those are different numbers and we keep them apart. Our results page publishes only cash reimbursed and reconciled — a smaller figure, and the one you should judge us on.
Three things we believe
The window changed, and the industry did not.
When Amazon cut the claim window from eighteen months to sixty days in late 2024, recovery stopped being an audit and became a monitoring job. Most of the category still sells the audit. We run the monitor.
Fee errors matter more than anyone admits.
Lost inventory is a one-time loss. A wrong measurement is a recurring one, charged on every order until somebody corrects the record. It is less exciting than a five-figure inventory claim and it is usually worth more.
25% was always too much.
Especially now, when the recoverable pool is smaller and the work is more automatable than it was. We charge 10% because the tooling makes it viable, and because taking a quarter of a seller's own money back is a hard thing to justify twice.
Why a bulldog: not because it barks. Because it does not let go.
