A WMS, or Warehouse Management System, is a software application designed to support and optimize warehouse operations. It is used to manage and control the movement, storage, and tracking of inventory within a warehouse or distribution center.

A WMS provides real-time inventory visibility, enabling warehouse managers to track inventory levels, monitor product movements, and manage warehouse resources such as personnel, equipment, and space. The system also helps in managing order fulfillment processes, including order picking, packing, and shipping.

Typical features of a WMS include receiving and putaway management, inventory tracking and control, order management, picking and packing optimization, and shipping management.

WMS solutions can be integrated with other enterprise systems such as enterprise resource planning (ERP) software, transportation management systems (TMS), and supply chain management (SCM) software to provide a complete end-to-end solution for managing the entire supply chain.

The benefits of implementing a WMS include improved inventory accuracy, increased efficiency, better space utilization, improved order fulfillment speed and accuracy, and reduced operating costs.
