Welcome to our guide on preparing your catalog for syncing inventory with the Amazon Easy Sync app, in this article we will cover the following points: 

• Introduction to Amazon SKU
• Connect Your Shopify Products to Amazon Using SKUs
• Connect Your Shopify Products to Amazon Using Barcode
• Connect Your Shopify Products to Amazon Using Metafields
• Sync Products by ASIN 

To successfully sync your Shopify store with your Amazon Seller Central account, it's essential to have matching identifiers such as SKUs. If your SKUs don't align, you can use Barcodes, Metafields, or ASINs as alternatives to ensure a smooth integration. 

1. Introduction to Amazon SKU

1.1 What are SKU and Variant SKU? (In Amazon)

A SKU (Stock Keeping Unit) is a unique identifier for tracking products, while a Variant SKU refers to individual variations (like size or color) for syncing between Shopify and Amazon.

In Amazon:

1. Each product must have a unique SKU in your inventory.
2. Uploading a new SKU creates a new record in Amazon's catalog.
3. SKUs cannot be changed or reused.
4. You can create your own SKU or let Amazon generate one.

1.2 Where to Find Your SKU:

• Log into  Amazon Seller Central .

• Navigate to the  Manage All Inventory  section.

  • • Look for the SKU of the product you want to link.

      2. Check your SKU on Shopify:

      • Open your  Shopify Admin .

      • Click on  Products  and select the product.

      • Scroll down to see the SKU. Make sure it matches the one from Amazon!
        
        

      • 3. Sync Using SKU:

        • When importing products, select the field for import as  SKU . 

        • All products with matching SKUs will be automatically synced to the app. That's it! By matching SKUs, you can easily manage your inventory between Shopify and Amazon.
          
          

       

      Locate your SKU in the product details column.
      
      

      2. Connecting Shopify Products to Amazon: Three Effective Methods

      2.1 Connect Your Shopify Products to Amazon Using SKU

      Match Shopify SKU with Amazon SKU. Connecting your Shopify products to Amazon with SKUs (Stock Keeping Units) is quick and easy! Just follow these simple steps:

      Steps to Connect Using SKU:

      • 1. Find Your SKU on Amazon:

        • Log in to your  Amazon Seller Central .

        • Go to  Manage All Inventory .

      

• Ideal situations for using the "SKU" mapping method:

  • When your Shopify and Amazon SKUs are the same : If the SKUs match on both platforms, this is the easiest and fastest way to sync your products.
  • For stores with simple products : If your store doesn't have many different product variations or complex setups, using SKUs to connect Shopify and Amazon works smoothly.

  2.2 Connect Your Shopify Products to Amazon Using Barcode

  Match Shopify Barcode with Amazon SKU. Barcode is ideal for syncing products when SKUs on Shopify and Amazon don't match, providing a seamless connection and simplifying inventory management.

  Steps to Connect Using Barcode:

  • 1. Find Your Product's SKU on Amazon (Used for Barcode Mapping):

    • Log in to  Amazon Seller Central  and go to  Manage All Inventory .

    • Locate the SKU for the product you want to connect.

  

  • 2. Check Your Barcode on Shopify:

    • Open your  Shopify Admin , go to  Products , and select the product.

    • Scroll down to make sure the Barcode on Shopify corresponds to the SKU used on Amazon.

    

  • 3. Sync Using Barcode:

    • When importing products, select the Barcode option for Shopify.

      Products with matching Barcode (mapped to SKUs) will automatically sync to the app. That's it! Syncing by Barcode makes inventory management easier, ensuring your stock is always up to date. 

      

   

  • Ideal situations for using the "Barcode" mapping method:

    • When SKUs are different but you have Barcodes : If the SKUs on Shopify and Amazon don't match, but your products are tagged with Barcode, barcode mapping is the best solution to sync them.
    • When Shopify has Barcode, but Amazon has SKUs : If your products on Shopify have Barcode that match the SKUs on Amazon, you can leverage Barcode for a quick and easy sync.

   

  2.3 Connect Your Shopify Products to Amazon Using Metafields

  Match Shopify Metafields with Amazon SKUs. Metafields provide a flexible way to connect your Shopify products to Amazon when SKUs or Barcode don't align. You can assign a unique identifier using either product or variant-level Metafields to enable smooth synchronization.

  What Are Product and Variant Metafields?

  • Product Metafields : Used for the entire product, replacing the SKU as the main identifier for syncing.
  • Variant Metafields : Applied at the variant level (eg, size or color), allowing unique identifiers for each product variant.

  Steps to Connect Using Metafields:

  • 1. Setting Up Metafields in Shopify :

    • Go to  Settings  >  Custom Data  in your  Shopify Admin .

    • Choose  Products  for a general product identifier or  Variants  for specific product variations.

      

  • 2. Create a New Metafields Definition :

    • Click  Add definition  to create your custom Metafields.

    • For a product-wide identifier, select  Products ; for a variant-specific one, select  Variants .

      

  • 3. Define Your Metafields :

    • Give your Metafields clear and simple names so they're easy to manage and use later.

    • In  Select Type , choose "Single Line Text".

      

  • 4. Apply and Save Metafields Values :

    • After defining the Metafields, open your product in  Shopify  and scroll to find the new  Amazon SKU  section. Enter the Amazon SKU here.

    • For variant-specific products, select each variant and fill in the new Metafields with the matching Amazon SKU.

      

      

      • Ideal Situations for Using the Metafields Mapping Method:

        • When SKUs or Barcodes Do Not Align: Use metafields to create unique identifiers for products or variants that lack matching SKUs or barcodes, ensuring smooth synchronization between Shopify and Amazon.

        • For Complex Product Variations: Apply variant metafields to manage unique identifiers for specific product variations (eg, size or color), allowing for accurate tracking and synchronization of each variant on both platforms.

      
      2.4 Sync Products by ASIN 

      1. Modify Link Criteria : You can tweak the link criteria and save your connection and marketplace settings. Just a heads up—if you don't change anything, nothing will happen!

      2. Save Your Configuration : After fetching the catalogs, don't forget to save your settings!

      

    • Changes in Linking Style:

      Amazon Linking Style: The process has been updated to avoid re-fetching the entire Shopify catalog. Now, it will only relink products, making the process faster.

      Shopify Linking Style: You can now link products using SKU or Barcode. Like Amazon, this method will not re-fetch the entire Shopify catalog; it will only relink products for improved speed.

    • NOTE: The metafield linking style remains unchanged and still requires fetching the entire Shopify catalog to relink products.
      

  This option to sync by ASIN is exclusive to our Pro and Enterprise Merchants. If you wish to sync by ASIN, upgrade your plan and feel free to contact support for further assistance! 

• Ideal Situations for Using the ASIN Mapping Method:

  • When Working with Established Amazon Listings: Use the ASIN mapping method for products that already have established listings on Amazon, allowing for efficient synchronization without the need to re-fetch the entire Shopify catalog.

  • For Merchants with Multiple Variants: This method is ideal for merchants managing numerous product variants that share the same ASIN, enabling streamlined updates and linking across platforms without redundancy.
