Duplicate SKU Sync App helps to keep the stock levels of items having the same SKU in sync.


The app can help sync the duplicate SKUs in 2 ways:


A. Limited Sync

Sync stock levels of duplicate SKUs when:

  1. there is an order placed on Shopify.
  2. there is a refund processed.
  3. the item is restocked via the app dashboard.


B. Full Sync

Sync stock levels of duplicate SKUs when:

  1. there is an order placed on Shopify.
  2. there is a refund processed.
  3. the item is restocked via the app dashboard.
  4. item stock is updated via Shopify admin or any other app.


Consider you have 3 products - productA, productB, and productC - all sharing the same SKU. Though the product listings are different, internally these 3 products are the same physical item. Hence, stock levels should also be the same. Assume the initial stock level of all the products to be 100 units.


1. Limited Sync


Let's say order has been placed for productA for 10 units. Shopify will automatically decrement the inventory of productA to 90 units.


The Duplicate SKU Sync app will then update the stock levels of productB and productC to 90 units within a minute's time. This ensures that the inventory of all the 3 products having the same SKU remains equal. 


Note, that with limited sync, the app updates the inventory of duplicate SKUs only when an order is placed on Shopify. It does not update the inventory of duplicate SKUs when the item stock is manually updated in Shopify or restocked via suppliers' transfers.



2. Full Sync


Full sync is a completely automated solution for keeping the duplicate SKU stocks in sync in real time. It supports syncing stock levels when inventory is manually updated via Shopify admin or it is restocked via transfers from suppliers.  


Let's say productA, productB, and productC (having the same SKUs) are stocked at 100 units each. If you update productA to 90 units via Shopify admin, the app will sync productB and productC to 90 units within a minute. This helps save time and prevents overselling.



Notes:


The app can sync items distributed across multiple locations. To know more read here.
