Shipping affects buyer satisfaction, your seller rating, and Amazon performance metrics. Run through this checklist on every order you ship.

1. Packaging. Use secure, protective packaging that meets Amazon's guidelines and prevents in-transit damage.
2. Labeling. Print clear shipping labels with the correct address and barcodes so the carrier can route the package without delays.
3. Shipping speed. Pick a service level that meets the delivery date you promised on Amazon.
4. Carrier selection. Use a carrier Amazon supports, and make sure the carrier provides tracking.
5. Weight and dimensions. Measure and weigh the package accurately to avoid surprise charges or carrier rejections.
6. Compliance. Follow Amazon's shipping and product handling requirements (hazmat, fragile, etc.).
7. Tracking and confirmation. Add the tracking number to the order and confirm dispatch so the shipment syncs to Amazon.
8. Customer communication. Keep the buyer updated on shipping status and respond to any issues quickly.

Following these consistently helps you maintain a positive seller rating and avoid delays or penalties from Amazon.
