Where are inventory settings?
Go to Settings > General settings.
Under Inventories, click the Edit button.
Click on the name of the inventory.
Inventory settings
In the Name field, you can set a name for the inventory (useful if you have multiple warehouses).
In the Inventory overselling menu, you can choose whether the customer can buy more products than is available.
In the Description field, you can enter a description of the inventory (again, this can be useful if you have several inventories and want to describe in more detail what the inventory is for).
