Warehousing as a concept refers to storage of goods which are produced either at a particular geographical location, or at a particular season of the year, or are imported and exported in bulk from a region.

The management of the warehouses, the goods and keeping a track of its stores is the Warehouse Management System. Some leading warehouses can be seen in Firth.
