In the Manage Orders page, an order with a status of Pending might indicate an issue with the buyer's payment method. In some cases, our payment and order detail verification processes can potentially extend order processing times for as long as 21 days.
Here are some of the most common reasons for orders being in Pending status:
Do not ship an order while in Pending status, even if the buyer contacts you directly. If a buyer contacts you while an order is in Pending status (for example, to cancel a pending order), refer them to Amazon Customer Service for more information.
Notes for seller-fulfilled orders in pending status:
To initiate communication, see Contact a buyer.
To identify orders with a Pending status, go to the Manage Orders page in Seller Central and click on the Pending tab. All Pending orders that are to be fulfilled by Amazon can be found on the View FBA orders tab. Pending orders does not appear in either your Orders report or Unshipped Orders Report. However, your inventory will be updated to reflect the order. For more information, see Manage your orders.
