To update the inventory of sold-out products on Etsy, simply add inventory to the product in Shopify. The app will auto-sync the changes based on your current sync settings. After that, run the **"Update Price and Inventory"** action in the app — this will update the inventory on Etsy accordingly.

1. Select the products you want to update

2. Click on "three dots" to open bulk action dropdown.

3. Click on Update Price & Inventory.

4. Confirm when pop-up asks, "Are you sure you want to sync the updated price and inventory on Etsy?"

 It will be updated!
