A Warehouse Management System (WMS) is a specialized software application designed to support and optimize warehouse operations. It manages inventory tracking, picking, packing, shipping, and receiving processes in real-time, improving accuracy and efficiency in storage and fulfillment. By providing detailed visibility into inventory levels and locations, a WMS enables better space utilization, reduces errors, and accelerates order processing. Integration with other supply chain systems like ERP and transportation management enhances end-to-end coordination, leading to optimized inventory levels and faster turnaround times.
