What Is Inventory Management?

Have you ever wondered how you walk into your favorite store and find everything you need, perfectly stocked and easy to locate? The answer lies in inventory management. 

At its core, inventory management oversees a company’s stock of everything it needs to function, from raw materials to finished products. Think of it like keeping your pantry stocked just right. You wouldn’t want to run out of your favorite cereal, but you don’t like many boxes going stale.

Inventory management in automobile industry is similar. Businesses need to have enough of everything on hand to meet customer demands. But not so much that they are overstocking or tying up too much capital in inventory. In this article, you will learn inventory management’s benefits, methods, and challenges to help you manage your business better.

Importance of Inventory Management

Beyond ensuring you do not run out of stock for your business, inventory management has other benefits, including:

Customer Satisfaction

Keeping track of inventory ensures that your customers can find the products they want when they want them. Nothing is more frustrating for a customer than discovering that their desired product is out of stock.

Cost Control

Overstocking can lead to high storage costs and an increased risk of spoilage for perishable goods. On the other hand, under-stocking can result in missed sales opportunities.

Operational Efficiency 

By keeping accurate records of inventory, businesses can streamline their operations. It reduces the time spent searching for items or processing orders, leading to faster delivery times.

Inventory Management Methods

Various methods are employed to achieve these goals, and each has its unique approach and benefits. The common methods include:

Just in Time (JIT)

The goal of JIT is to decrease waste and increase efficiency by receiving goods as they are needed in production. This approach reduces carrying costs. Although it requires accurate demand forecasting and highly reliable suppliers to deliver exactly when needed to avoid stock-outs.

Material Requirements Planning (MRP)

Material Requirements Planning (MRP) is a system for managing manufacturing processes by determining the materials and components needed to produce a product. It involves scheduling production runs and ordering necessary raw materials in the right quantities at the right times. However, its implementation can be complex as it requires accurate data. It may also not reflect changes in demand and production schedules.

Economic Order Quantity (EOQ)

EOQ calculates the ideal order quantity for minimizing inventory costs. The goal is to find the most cost-effective quantity to order each time replenishment is needed. It seeks to balance ordering and holding costs. The challenge with EOQ is that it assumes a constant demand, which may not always be the case.

Days Sales of Inventory (DSI)

DSI shows how long it takes for a company to sell its entire inventory. This metric provides insight into inventory efficiency and management effectiveness. DSI can vary significantly across industries, making comparisons tricky.

Challenges in Inventory Management

Despite the best tools and techniques, managing inventory comes with its set of challenges, including:

• Unpredictable changes in customer demand make it hard to maintain optimal stock levels.
• Supply chain disruptions lead to stock-outs or excess inventory.
• Inaccurate data leads to poor decision-making and inventory discrepancies.
