A _warehouse_ is the physical place with an address from which product items can be shipped. Optimizely Customized Commerce includes the option to add and track a list of _inventory_ _locations_ within the system. When creating a new product variant (SKU), specify the item's warehouse and inventory information.
Customized Commerce has support for _multiple inventory locations_ (previously labeled warehouses). The warehouse label is kept to be consistent with the past, but the current definition is that a warehouse is any place that contains an inventory that you can track, whether it is a warehouse used for shipping, individual stores, a factory, or whatever is required for monitoring available items. You can even include trucks that are delivering orders.
