An Inventory System is a structured method used by businesses and organizations to monitor, manage, and control the flow of goods, raw materials, and finished products within their operations. It ensures that the right products are available in the right quantities, at the right time, and in the right place. By keeping track of stock levels, movements, and usage, an inventory system helps reduce waste, optimize resources, and improve overall efficiency.
