A warehouse is a facility used to store goods and materials before they are needed, sold or sent elsewhere. It also provides space and systems for receiving, locating, handling and releasing that stock.
Warehouses hold finished products, raw materials, components, spare parts and other supplies. Manufacturers, retailers, wholesalers and logistics providers use them. Facilities vary in size, layout and degree of automation.
What happens inside a warehouse?
A typical operation begins with receiving: staff check an incoming delivery against its records and inspect its condition. Putaway means moving accepted goods to assigned storage locations.
When an order arrives, picking brings the required items out of storage. Staff then check and pack them, prepare shipping records and hand the shipment to a carrier. Returns may follow a separate inspection and restocking process.
A warehouse management system (WMS) is software that records stock locations and movements and helps coordinate these activities. DHL’s explanation of warehouse systems describes receiving, putaway, picking, packing and dispatch. Software records still depend on accurate processes and data.
An order moving through a warehouse
Suppose a fictional retailer receives 120 identical boxed kettles. Staff check the delivery, record 120 units and place them in assigned storage locations.
A customer then orders three kettles. A picker retrieves three units, which are checked and packed for shipment. After those three leave, 117 remain in the warehouse, assuming no other receipts, shipments, losses or returns.
Picking is not the same as shipping: a picked item may still be inside the building awaiting packing or collection. Inventory records can distinguish stock on the shelf, stock reserved for orders and stock already dispatched.
Warehouse, distribution center and fulfillment center
Warehouse emphasizes storage. A distribution center emphasizes moving goods through a network, often supplying stores or other businesses. A fulfillment center focuses on preparing and shipping customer orders, commonly individual online purchases.
These functions overlap. One building can store reserve inventory, replenish shops and fulfill consumer orders. DHL’s distribution-center guide notes that facilities often combine storage and order-handling areas. The names do not impose a universal rule about how long stock must remain inside.
A warehouse store is a different retail use of the word: customers buy goods in a warehouse-style shop.
Different products need different facilities
General warehouses can hold goods suitable for ordinary storage conditions. Refrigerated facilities maintain the temperature conditions required for their stock. Other operations handle bulk materials or products needing particular security or handling arrangements.
Bonded warehouses are subject to customs rules. For example, US regulations distinguish several classes, including private and public bonded warehouses and bonded yards or tanks. The exact customs treatment depends on the goods and procedure.
Racks, pallet trucks, forklifts, conveyors and automated equipment support different tasks. A facility can operate with a mixture of manual and automated work; robots are not part of the definition.
The US Occupational Safety and Health Administration identifies risks associated with materials handling, lifting, vehicles and storage. Safe layout, equipment and work practices matter alongside stock capacity and speed.
Warehouse and warehousing
The noun describes the facility. The verb to warehouse means to place or keep goods in storage. Warehousing describes the storage and related handling activities, and also has separate meanings in finance.
