warehousing and order fulfillment refers to the process of storing goods in a warehouse and handling their order processing, picking, packing, and shipping. Businesses often use third-party logistics (3PL) providers to manage warehousing and fulfillment services. These providers store inventory in their warehouses, process orders as they come in, and ship products to customers. Outsourcing fulfillment allows businesses to focus on growth while reducing the overhead of managing inventory and shipping logistics. Fulfillment services often include inventory management, returns processing, and tracking.
