The Duplicate SKU Sync app lets you restock inventory for all products and variants sharing the same SKU in a single update.
Instead of manually adjusting inventory for each duplicate product in Shopify, you can update them all at once from the app.
How to Restock Inventory
1. Open the Inventory Page
Launch the Duplicate SKU Sync app and navigate to the Inventory page.
2. Select a Location
Choose the Shopify location where you want to update inventory.
This step is only applicable if your store has multiple locations.
3. Search for the SKU
Enter the SKU you want to restock and click Search.
The app will display all products and variants that share the same SKU.
4. Update Inventory
Enter the new inventory quantity and click Update.
The app will automatically update the inventory for all duplicate products and variants using that SKU at the selected location.
