Inventory: Meaning, Functions, Types and Need for Holding Inventory

 Inventory

Inventory is an American term equivalent to the British term “stock.” It refers to the materials and goods stored within an organization that exceed immediate operational requirements. Inventory represents the stored quantity of goods maintained for future use, production, or sale.

Inventories include the stock of products that a company manufactures for sale, as well as the components and materials used in the production process. Inventory constitutes a significant portion of current assets, often accounting for around 60% of total current assets in manufacturing and trading organizations.

Inventory may be defined as a stock or store of goods, commodities, or other tangible resources held by an organization at any given point in time for future production or sale. It also refers to the aggregate of tangible personal property that:

1. Is held for sale in the ordinary course of business,
2. Is in the process of production for such sale, or
3. Is to be currently consumed in the production of goods or services available for sale.

Components of Inventory

Inventory typically includes:

1. Raw materials and purchased parts
2. Partially completed goods (work-in-progress)
3. Finished goods or merchandise
4. Replacement parts, tools, and supplies
5. Goods in transit to warehouses or goods in progress

Forms of Inventory

1. Raw Materials – Basic inputs that are converted into finished products through the manufacturing process.
2. Supplies (Stores and Spares) – Items used for maintenance and operations but not directly part of the finished product.
3. Work-in-Progress (WIP) – Semi-manufactured goods that require further processing before becoming finished goods.
4. Finished Goods – Completely manufactured products that are ready for sale to customers.

Inventory System

In simple terms, inventory is a physical resource that a firm holds in stock with the intention of selling it or transforming it into a more valuable form. An inventory system refers to the set of policies and controls used to monitor inventory levels, determine how much inventory should be maintained, decide when stock should be replenished, and specify the size of orders to be placed.

Functions of Inventory

1. Decoupling of Production Processes Inventory helps to separate or decouple different stages of the production process, allowing each stage to operate independently and smoothly without interruptions.
2. Protection Against Demand Fluctuations Inventory enables the firm to meet unexpected changes in customer demand and ensures the availability of a variety of goods for customers at all times.
3. Economies of Scale and Quantity Discounts Holding inventory allows firms to purchase materials in bulk and take advantage of quantity discounts, thereby reducing per-unit costs.
4. Hedging Against Inflation By maintaining inventory, firms can protect themselves against rising prices by purchasing materials at current lower prices.

Need for Holding Inventories

1. Transaction Motive Inventory is held to ensure smooth and continuous production and sales operations by bridging the time gap between purchases, production, and sales.
2. Speculative Motive Firms maintain inventory to benefit from expected price increases, shortages, or favorable market conditions in the future.
3. Precautionary Motive Inventory is held as a safeguard against uncertainties such as delays in supply, sudden demand increases, strikes, or transportation disruptions.
