A Warehouse Management System (WMS) is a specialized software designed to track and control everything that happens inside a warehouse, acting as the "brain" of the facility. It automates tasks like keeping an accurate count of inventory, organizing where items are stored so they are easy to find, and managing the process of receiving new shipments or picking orders for delivery. By providing real-time data on exactly what is in stock and where it is located, a WMS helps businesses reduce human error, speed up shipping times, and ensure that the right products reach the right customers efficiently.
