Inventory tracking systems have developed a lot over time. Many years ago inventory tracking systems consisted of manually writing down each inventory transaction on a file card known as a cardex.

An inventory control system is a system the encompasses all aspects of managing a company’s inventories; purchasing, shipping, receiving, tracking, warehousing and storage, turnover, and reordering.

Inventory production management involves keeping track of products, suppliers, stock levels and purchase orders, reordering products, and managing information related to inventory and production.
