Processing orders with the Amazon sales channel
When a customer buys one of your products on Amazon, you'll receive notifications about their order from Amazon Seller Central and on the Overview page of the Amazon sales channel in your Shopify admin.
Orders can take up to 30 minutes to sync back with Shopify.
The inventory number that you allocated for that product when you created the listing in Shopify will update (but not your actual inventory level for that product in Shopify). You can log in to your Amazon Seller Central account to review the order details and manage billing and fulfillment.
Your orders on Amazon automatically sync up with your Shopify admin on the Orders page. All new orders placed through Amazon appear in your orders list and are marked as Amazon. The Amazon sales channel syncs all your orders, including orders for products that you didn't use the channel to list on Amazon.
Your customers receive order notifications from Amazon only, and you receive notifications from both Amazon and Shopify.
You need to fulfill the order in your Shopify admin to make sure its status is updated in Shopify. When you fulfill the order in Shopify, it is automatically marked as fulfilled on Amazon. If you process a refund in Shopify, then you will receive an email from Amazon to process the refund in Amazon Seller Central.
At this time, you can't fulfill Amazon sales channel orders using Fulfillment by Amazon. Instead, you need to manually fulfill orders placed through the Amazon sales channel in your Shopify admin. This is known on Amazon as Fulfillment by Merchant or seller-fulfilled.
When you're fulfilling orders from Amazon, make sure that you follow Amazon's Selling Policies.
Get paid for orders
You can view payments from the Amazon sales channel in your Amazon Seller's Central in the Reports section. Learn more about getting paid at the Amazon Pay help center.
