Multi-Warehouse Support are warehouse systems that allow you to have separate physical fulfillment centers in different locations around the country/world. For these WMS' we can load inventory levels per fulfillment center and report that detailed inventory back to supported carts and order sources. This functionality is particularly important for EDI order sources.
 

For information on setting this functionality up in Extensiv Integration Manager and options when syncing inventory to your shopping carts, visit: Multi-Warehouse Inventory Setup.
