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

The main function of a warehouse management system (WMS) is to manage inventory control and operations. A WMS is designed to optimize warehouse functionality and inventory management by providing tools for tracking inventory levels, orders, deliveries, and warehouse operations in real time. This system plays a crucial role in streamlining processes such as receiving, picking, packing, and shipping of goods, ultimately enhancing efficiency and accuracy in managing the flow of products.

While organizing the layout of warehouses can be a part of operational planning, it is not the primary purpose of a WMS. Similarly, overseeing employee scheduling and facilitating marketing for storage facilities do not align with the core functionalities of a WMS, which focuses specifically on inventory management and optimizing warehouse operations.
