To quickly see a list of your orders, use the tabs on the Manage Orders page in Seller Central for a list of all Unshipped, Pending, Shipped, and Canceled orders.
The best source for order information is the Orders Report, which you can download from Seller Central. An orders report is posted every 24 hours. You can also manually generate an orders report for the past 1, 2, 7, 15, 30, 60, or 90 days.
If email order notifications are enabled in your account settings, you will also be sent an email notice for each order when that order clears the Amazon Payments system.
