What is the primary function of a warehouse management system (WMS)?

The primary function of a warehouse management system (WMS) is to oversee warehouse processes. A WMS is designed to facilitate efficient management of the storage, retrieval, and shipping of inventory within a warehouse. It helps in optimizing the use of space, managing stock levels, tracking inventory movements, and improving the overall workflow of warehouse operations. By integrating various functions such as receiving, putaway, order picking, and shipping into a cohesive system, a WMS enables organizations to enhance productivity, accuracy, and efficiency in their warehouse operations. This centralized management of activities allows for better resource allocation and improved service levels, which are crucial for meeting customer demands in a timely manner.

Other options, while they may relate to aspects of warehouse operations, are not the primary focus of a WMS. For instance, shipping costs are influenced by various factors and managed through different systems. Customer relations are typically handled through customer relationship management (CRM) systems, focusing on interactions with customers rather than the operational processes in a warehouse. Tracking employee productivity is important but usually falls under human resource management or performance tracking systems rather than the core functionalities of a warehouse management system.
