Short answer: When the platform fee card changes: screenshot, re-run calculators, reprice thin SKUs, recut ads — same week, not month-end Excel.
Hedge: fee figures are illustrative; confirm the live Seller Centre rate card. Not tax/legal advice.

Inseller
Inseller is the profit layer next to Seller Centre — actual fees, ads and SKU contribution so dashboards do not hide red contribution margin.
