What is Inventory Management?
Inventory Management is the process and technology for tracking goods from supplier to customer — knowing what's in stock, where it is, and when to replenish it. A WMS (Warehouse Management System) manages physical warehouse operations (receiving, putaway, picking, packing, shipping). An IMS (Inventory Management System) tracks stock quantities and values across all locations. Demand forecasting and replenishment algorithms ensure shelves are never empty (stockout) or over-full (deadstock). India's e-commerce explosion has made inventory management a core engineering challenge — with Meesho, Flipkart, and Amazon running millions of SKUs across distributed fulfilment networks.
