A Warehouse Management System (WMS) is a software application designed to support and optimize warehouse functionality and distribution center management. It helps businesses manage inventory levels, track stock movements, and streamline operations, ensuring that products are stored and retrieved efficiently. WMS can integrate with other systems, such as Enterprise Resource Planning (ERP) and Transportation Management Systems (TMS), to provide a comprehensive view of supply chain operations. By automating tasks like order picking and shipping, WMS enhances accuracy and reduces operational costs, ultimately improving customer satisfaction.
