Warehouse management plays a critical role in modern supply chain operations. With the rapid expansion of global trade, e‑commerce platforms, and complex logistics networks, organizations increasingly rely on advanced technological systems to manage warehouse activities efficiently. A Warehouse Management System (WMS) is a specialized software platform designed to control, coordinate, and optimize warehouse operations such as receiving goods, inventory management, order picking, packing, and shipping. This study explores the role of warehouse management systems in improving warehouse efficiency and overall supply chain performance. The research uses a qualitative approach based on secondary data collected from academic journals, books, and industry publications. Existing literature was analyzed to identify the functions, advantages, and challenges associated with implementing WMS technologies. The findings suggest that warehouse management systems significantly improve inventory accuracy, increase operational efficiency, reduce human error, and enhance order fulfillment speed. Furthermore, modern WMS platforms integrate emerging technologies such as cloud computing, automation, artificial intelligence, and the Internet of Things to create smart warehouse environments. Despite these benefits, organizations may face several challenges during implementation, including high initial costs, employee training requirements, and system integration complexities. The study concludes that warehouse management systems are essential tools for modern logistics management and will continue to play a significant role in improving supply chain efficiency in the future.
