Once you have added multiple store locations and enabled inventory tracking, each product will show new options to manage inventory by location, rather than by product or variable.
Along with managing inventory per location, you can manage orders for every location added.
When a customer completes an order at a store location, the inventory will be managed from that location.
After the product has been shipped, the product stock on that location will be automatically reduced.
If you want to learn more about orders, refer to the Orders page.
