If you have been actively selling on Amazon, and now want to connect Shopify products to your Seller Central inventories, Salestio has an easy way to do so. The app offers a few customizations and options for product connection, so in this article we will explore the possibilities and explain the process.


Before proceeding with any of the below steps, connect the Amazon account to Salestio. This can be done in Salestio > Accounts tab.

The article assumes that the Seller Account already has some listings published on Amazon. For a guide to publish Amazon items through Salestio, check out the post below:

To successfully connect the items between platforms, the products must have matching SKUs. We will present a few solutions for cases when the SKUs do not match, keep reading for more details.

Create a Selling List

Adding a Selling List is an optional step that can help to organize the products inside the app before they are connected. Creating a Selling List manually can be useful for the following reasons:

  • Customizing the rules for quantity and price synchronization. Default Salestio settings use the current Shopify price and quantity, so check the guides below to learn more about setting specific rules:
    Custom Pricing Rules for Ebay and Amazon Listings
    Manage Listing Quantities with Salestio
  • To have the option of connecting existing listings with Shopify and publishing new products to Amazon. For example, add all desired items to a Selling List, link the existing products, and run the “Send to Amazon” action for the rest of the items.
  • The convenience of sorting different product categories into different Selling Lists. Having different product groups in a separate list can make it easier to view and manage the products.

If you skip creating a Selling List at this step, Salestio can automatically create a “Migrated…” Selling List when syncing products.

Download the inventory list from Amazon

To start the linking process, we must retrieve the available Amazon listings on the account. Go to Salestio > Inventory tab and click “Download inventories to get started. When multiple Amazon accounts are connected, they will appear as selectable options. Select the target account and click “Download”.

Depending on the Amazon product count, it may take 30 to 60 minutes to display all of the products in Salestio.


Salestio uses the product SKU to find item pairs and establish a connection. If the SKUs already match, skip to the next step and start connecting the products.

Consider the two options to resolve the SKU matching:

  • Edit the Shopify products to match the SKUs to Amazon.
  • Configure an SKU mapping in Salestio without making edits to any of the products.

Connect the items and review the results

To start the connection process, click the “Sync inventories with selling products” button in the Inventory tab. Select the target Amazon account and marketplaces and start the sync.

As another option, you can link individual items. Find the target item in the list and click the “Move to Selling List” button. Select the Selling List, and Salestio will create a connection.

Click “Move to Selling List” to link individual items

Check the results in the Selling Lists tab. If you created some Selling Lists beforehand, the items will remain there, but the status will change to “Linked”. It means that the connection between Shopify and Amazon products is established, and Shopify stock and prices will be synced to Amazon. If Salestio finds some items that were not in any of the Selling Lists, they will appear in an automatically created one called “Migrated for account_name amazon_marketplace

Salestio will sync the “Linked” items in the background when stock or price changes in Shopify. If you would like to push the stock and/or price numbers from Shopify to Amazon immediately, run this action manually from the Selling Lists tab.
Select the Selling List (or individual items inside) and run one of the update actions (Update QTY, Update Price, Update QTY & Price).

Sort the linked items

If you want to sort the items later, select them in the Selling List and click the “Move” action to place them in another Selling List. This can be done whether the item is linked or not. Keep in mind that the products can be moved between Selling Lists with the same Seller account and marketplace.

Possible errors

Depending on the app and Seller account configuration, some steps might not go as planned. Let’s review the possible cases.

Products missing from the Inventory tab

Salestio downloads the items from the selected account and marketplace. This is important to keep in mind when retrieving the list from Amazon.

Check the account connection in Salestio and ensure the correct settings. Linked accounts will have an “Active” badge, as well as the list of connected marketplaces. If some marketplaces are missing or the account shows up with a red badge, try reconnecting it. Click the account in the list, select the marketplaces, and click “Save account” at the bottom.

Some items remain Not Linked

To link the items, Salestio checks if the SKU, account, and marketplace match. Please try the steps below to find out the issue:

  1. Check if the SKU matches for the Amazon – Shopify item pair. If the SKUs are different, assign the correct one in the Inventory tab and try syncing again. Consider other options to match the SKUs: editing the Shopify product page directly or setting up an SKU mapping to establish the SKU pairs.
  2. Check if the correct account and marketplace are selected in the Selling List. This can be viewed from the Selling Lists tab. For example, if you need to link an item from Amazon IT, the Selling List has to be configured with the Italian account and Italy marketplace. If the product was placed in a list with incorrect settings, Salestio will also add it to a “Migrated…” Selling List for the respective marketplace.
    Account and marketplace selection is locked after a Selling List is created. To select something different, please create another Selling List.

Salestio assists the sellers at integrating an already running Amazon store into the Shopify inventory management. By following the steps from this article, you can sync the two platforms in a few simple steps. Don’t have Salestio yet? Find the app on the Shopify App Store and start a Free 30-Day Trial.
