What 2-Step Actually Fixes

Under Amazon Policy G201808410, you must be the seller of record on every packing slip, invoice, and external shipping box. In the 2-step model:

  • Third-party supplier boxes and retail markings are completely removed.
  • Your business name and custom branded packing slip are inserted.
  • Customer receives a compliant parcel with you as the visible shipper.

What 2-Step Does NOT Fix (The Invoice Checkpoint)

Rerouting a Walmart, Target, or Costco box through a warehouse does NOT create a valid invoice. In 2026:

  • Amazon auto-rejects retail receipts during authenticity reviews.
  • Over 85% of non-compliant dropship accounts are suspended within 30 days of first audit.
  • Only wholesale distributor invoices with commercial lot numbers survive.
