Most businesses carry some inventory. In this lesson, you'll learn about what inventory is, some related concepts and be provided examples along the way. A short quiz follows the lesson.

Definition of Inventory

Inventory is a quantity of goods owned and stored by a business that is intended either for resale or as raw materials and components used in producing goods that the business sells. For example, motherboards warehoused at a computer company to be used in the assembling of its computer systems are inventory. The products displayed for sale and stored in the backrooms of a department store are inventory as well.

Inventory Control System

An inventory control system is a process a business uses to manage inventory. There are several different types of inventory control systems. Let's look at some of the more common systems.

Continuous review system: Under a continuous review system, inventory is continuously monitored. When the inventory of a particular good or product reaches a predetermined level, an order for a predetermined quantity of additional inventory will be placed. For example, a retail store may order six more coffee machines to sell when it's down to only three in inventory. Other names used for continuous review systems include event-triggered systems, fixed order size systems (FOSS) or economic order quantity systems (EOQ).
