SellerShock Response Checklist 1. Identify the top 10 SKUs by monthly gross profit, not just revenue. 2. Mark every SKU whose post-surcharge net margin drops below your target. 3. Separate "raise price now" SKUs from "cost out or pause ads" SKUs. 4. Check whether delivery lag has lengthened beyond what your cash plan assumes. 5. Re-forecast reorder timing using the delayed payout window, not your old payout habits. 6. Review ad campaigns that only made sense under the old margin structure. 7. Ask suppliers where packaging, MOQ, or freight savings are realistic this month. 8. If reserve exposure is high, reduce optional inventory bets before they turn into a cash squeeze. 9. Communicate pricing changes to internal stakeholders before inventory turns force a rushed move. 10. Re-run the model whenever surcharge policy or delivery lag changes again.
