Item quantities are tracked from the item details screen. The app gives you the ability to track item variations independently in one or more locations.
The item details screen contains a list of all your locations. When a location is enabled, it means that inventory is actively being tracked there. Disabling a location removes any inventory associated with that place. Disabled locations will not generate low and out of stock alerts, and will not contribute to inventory totals. The default location is enabled by default and shows the quantity level associated with each variation.
