Stock control, also known as inventory control, is the process of managing and regulating the levels, movement, and storage of inventory within a business. It ensures that the right amount of stock is available at the right time to meet customer demand while minimizing holding costs and preventing overstocking or stockouts. Effective stock control is vital for maintaining operational efficiency, reducing waste, and supporting customer satisfaction.
