Manage your orders closely

Stay on top of orders by updating your notification settings.

Check your Seller app and Seller Central account frequently for orders and fulfill new orders daily. Do not rely solely on "Sold, ship now" emails to let you know you have orders. Review your notification settings here.

Provide accurate product data

Use unique standard identifiers (JAN/ISBN/UPC/EAN) when creating or matching to product detail pages. Make sure your product description and condition notes are clear and helpful to buyers.

Check your inventory regularly

Keep an eye on quantity of inventory you have in stock, especially if you sell in multiple channels. Ensure you have enough inventory to fulfill your sales and avoid order cancellations due to inventory shortage. For more information on how to manage your inventory, visit Seller University here.

Staffing and Handling time

Review your staffing plans to ensure you have enough capacity to ship during the holiday season.

Be prepared for an increase in order volume during key sales periods, such as the run-up to the holiday season. List only those items you will be able to ship by or before the expected ship date. Learn more about managing orders here.

Streamline your Shipping and Fulfillment

Review your shipping templates and ensure that you can comply with the transit time set on the shipping templates. Weekend Operations will be optional. When enabled, these days will be considered in the calculation of the Expected Ship Date.

Ship orders prior to the Expected Ship Date when possible. Hand over packages when you send ship confirmation. Work with your local carrier account representatives to make sure they have enough capacity to pick up an increased volume of shipments, provide first scans the same day, and deliver them on-time.

Note: As a reminder, as of September 30, 2020, orders not shipped 7 days after the Expected Ship Date will automatically be canceled to protect the customer experience.

Provide great customer service

Make an impression on buyers that will last: provide excellent customer service during the holiday season. Make a point of responding to all of their inquiries within 24 hours. Add a personal touch to orders - include "thank you" notes on packing slips. Be courteous in your correspondence with buyers as per our communication guidelines, and address any problems quickly and professionally. Providing world-class service usually results in buyer appreciation.

Handle returns, refunds, and A-to-z Guarantee claims

Address A-to-z Guarantee claims and service chargebacks promptly. Check your A-to-z Guarantee claim pages daily, and proactively resolve any issues. To help prevent being held responsible for the reimbursement of a claim, follow our selling policies.
