Shopify is one of the most popular systems in the world, with almost 1,7 businesses worldwide using it. Amazon, on the other hand, is a top-ranked marketplace with over 2.5 million vendors and over 300 million active customer accounts globally. Without a doubt, combining these two top-notch platforms will provide you with significant benefits. This article will present you how to kick off your sales on Amazon with Shopify.
Why should you sell on Amazon?
Shopify retailers should consider selling on Amazon for a variety of reasons:

The Amazon sales channel can be used in three ways:
How to connect Shopify and Amazon
Check to see if you're eligible to use Amazon as a sales channel
The first step is to determine whether you are eligible to sell on Amazon's marketplace using Shopify. Eligible merchants sell products in one of the supported categories, with prices listed in USD or CAD. They also have an Amazon Professional Seller account, a Shopify plan that is active, and they are not using Amazon FBA.
The following Amazon categories are presently supported by Shopify:
Register as an Amazon seller
You'll need to create an Amazon Professional Seller account if you don't already have one. Professional Seller accounts are subject to a $39.99 monthly subscription cost from Amazon.
Go to Amazon Services and select Start Selling from the drop-down menu. Choose a password after entering your name and email address.

Amazon Seller Central
Provide Amazon with your business name and address, phone number, credit card and bank account details, and your Taxpayer Identification Number to complete the account setup.
Add Amazon as a selling channel to your store.
You'll need to activate the Amazon sales channel in Shopify after you've created a Professional Seller account and completed the account setup.

Amazon list
Option 1: If you already have an Amazon listing, you can claim it and link it to your Shopify store.
Go to Amazon > Listings, select Link products, then Browse products to find the item you wish to link. Select the relevant product, as well as any versions you'd like to include, once you've located it.

Click on Link products
Option 2: Make a product list of the product currently sold on Amazon
Create a policy for inventory tracking
For each Amazon listing that you add to your business, you'll need to create an inventory tracking policy. The following are the two alternatives available to you:

Manually inventory management: You can opt-out of having Shopify keep track of your inventory. With this option chosen, Shopify will set your product's inventory in Amazon Seller Central to 100, ensuring that it is always available for purchase.
Shopify can help you fulfill Amazon orders
You're now ready to use Shopify to fulfill Amazon orders!
When someone buys one of your products on Amazon, the order will appear in Shopify, and you'll be able to fulfill it just like any other Shopify order. To avoid running into troubles on the site and perhaps having your Amazon Seller account suspended, make sure you follow Amazon's handling and shipping criteria.
You'll have to deal with any Amazon order refund requests through Amazon Seller Central. To guarantee that all of your sales data is accurate, you'll need to manually record any refunds in Shopify.
Disconnect
If you want to disconnect your Amazon Seller account, go to your Shopify admin and change the settings for the Amazon sales channel.
Your products and order information are no longer synchronized with your Shopify admin if you disconnect your Amazon Seller account from your Shopify admin. The information about your goods and order is not deleted from Amazon. By reconnecting your Amazon Seller account to the Amazon sales channel, you can resume synchronizing product and order information.
