The app provides a shortcut to speed up the restocking of inventory levels of all the duplicate SKUs.
Instead of logging into the app and searching for the SKUs for updating inventory, you can directly move to update the inventory while visiting the variant page in the Shopify admin.
1. Visit any Shopify admin variant page that has duplicate SKUs and needs to be updated
2. Click the More Actions > SKU Sync button
3. This will take you to the Inventory page inside the app with the SKU and inventory level pre-filled
4. You simply need to verify and hit the Update button
Note, the 'SKU Sync' button is also available on the Shopify admin product page.
