What this catches

SKUs whose mapped fees, ads, returns and product costs exceed revenue.

Products with positive revenue but thin 0–10% estimated contribution margin.

A fragmented export that needs a repeatable column-mapping step before profitability review.

The exact cost bucket driving a bad row instead of one blended “profit” number.

Commercial wedge

Today: one browser-local audit. Paid later: keep it updated automatically.

The paid product should earn its fee by retaining mappings, joining repeated exports, monitoring SKU contribution and alerting on deterioration. We are not pretending that integration exists yet.

Open the full seller toolkit

Important: this tool does not parse or reconcile every Amazon report schema automatically. It only calculates from the columns you map. Missing cost columns are treated as zero, which can overstate profit. Reconcile results against your own Seller Central, advertising, inventory and accounting records.
