What to do when fees change

  1. Open the Fee Change Radar on your calculator — upcoming and recent events show automatically.
  2. Save SKUs to your margin watchlist with COGS and fee presets.
  3. Hit Re-run watches to see margin before vs after the new rate.
  4. Reprice inventory before the effective date — sellers who skip this absorb fee creep out of pocket.
