Here’s how to add inventory:

1. Edit a product by tapping Edit (iOS) or the pen icon (Android).
2. Swipe right on the button next to “Inventory tracking."
3. Add the correct number of inventory (for each variant) and tap Save.

Here’s how to add inventory:

1. Go to Product library.
2. Click into the product and check the box next to "Inventory tracking."
3. Add the correct number of inventory (for each variant) and click Save.

Notifications will let you know when items are running low, so you can restock in time. You can still sell a product even if you’re out of stock. At this point, the inventory count shows as negative (-1).
