An Order Management System (OMS) is a digital platform that enables businesses to efficiently manage the entire lifecycle of customer orders, from order placement to final delivery. It plays a crucial role in eCommerce and supply chain operations by centralizing order processing, inventory management, and fulfillment activities.

An OMS allows businesses to receive orders from multiple sales channels such as websites, marketplaces, and mobile apps and process them through a single system. It helps streamline operations by automating tasks like order confirmation, inventory updates, shipment creation, and status tracking.

The order management process typically begins when a customer places an order. The OMS captures the order details, verifies inventory availability, and routes the order for fulfillment. Once processed, the system coordinates with warehouses or shipping partners for dispatch and provides real-time tracking updates until the order is delivered.
