The process of canceling an order will vary, depending on the stage of the delivery process at which the item currently stands.
How to Cancel an Amazon Order After Shipping
As the seller, you can cancel orders any time prior to shipment. The buyer has approximately thirty minutes to cancel an order they have placed. Orders that have already been shipped cannot be canceled. If a cancellation request is submitted at this point, the seller should contact the buyer and inform him that the item has already been shipped. The buyer has the option to return the item for a refund. Find out all the details about returns and refunds here. The buyer’s contact information can be found within the Order ID or in the seller’s orders list. Once you find the specific order you want to cancel, press “Cancel Order” and select the reason for cancellation.
Canceling Orders That Have Not Been Shipped
If a seller needs to cancel an order either because the item will not be shipped on time or because the item is out of stock or for any other reason, and the item has not yet been shipped, he can do it through his Seller Account.
Access the Manage Orders section, and go to View Your Orders.
Sellers can browse through the orders manually or use either the standard search or advanced search options provided to find the specific order in question.
A Cancel Order button should appear somewhere in the close vicinity of the order (either next to or below depending on the page view). Press this button to cancel the order.……Read more>>
