Inventory Management: What It Is? Why Is It Important? And Its Types

Inventory management is one of the most important tasks for any business. It ensures that the company has enough goods on hand to meet customer demand, and doesn’t end up with too many or too few items.

This article takes a look at what inventory management is, why it’s important, and the most common types of inventory management systems used by businesses.

What is Inventory Management?

Inventory management is the process of keeping track of inventory levels, orders, and sales in order to ensure that businesses have enough stock on hand to meet customer demand. It is a crucial part of the supply chain and can have a major impact on a company’s bottom line.

There are several different types of inventory management methods, each with its own benefits and drawbacks. The right type of system for a particular business will depend on factors such as the nature of the product, the size of the inventory, and the company’s overall business model.

One of the most important aspects of inventory management is understanding and predicting customer demand. This requires careful analysis of past sales data in order to identify trends and seasonal fluctuations. Armed with this information, businesses can make more accurate decisions about how much inventory to keep on hand and when to order new products.

Just as important as understanding customer demand is having a system in place to track inventory levels and orders. This information must be accessible in real-time so that managers can make informed decisions about stock levels.

Why is Inventory Management Important?

Inventory management is important for a number of reasons.

  • First, it helps businesses keep track of their inventory and ensure that they have enough products or materials on hand to meet customer demand.
  • Second, it can help businesses reduce their costs by ensuring that they only purchase the amount of inventory they need and not more.
  • Third, effective inventory management can help to keep costs down by preventing overstocking and ensuring that stock levels are appropriate for current demand.
  • Finally, effective inventory management can help businesses avoid stock-outs and other disruptions in their operations.

Types of Inventory Management System

Inventory management is critical for businesses of all sizes. An effective inventory management system can help streamline operations, improve efficiency, and minimize waste. But what types of inventory management systems are there? And which one is right for your business?

There are three main types of inventory management systems:

  • Periodic,
  • Perpetual, and
  • Just-In-Time (JIT).
  1. Periodic inventory management systems are the simplest and most common type. In a periodic system, businesses take stock of their inventory at set intervals, such as once a week or once a month. This type of system can be manual or automated.
  2. Perpetual inventory management systems keep track of inventory levels in real time. That means that as soon as an item is sold, it is removed from the inventory count. This type of system requires more sophisticated technology, such as barcode scanners and point-of-sale (POS) systems.
  3. Just-in-time (JIT) inventory management is a type of perpetual system that takes it one step further by only ordering new stock when it is needed. This helps to minimize waste and keep costs down. JIT systems require even more sophisticated technology, such as sensors that can track stock levels.

Inventory Control Methods

There are many different inventory control methods that businesses can use to keep track of their inventory and ensure that they have the right levels of stock on hand.

Some of the most common methods include:

  1. First in, First out (FIFO),
  2. Last in, First out (LIFO), and
  3. Just in Time (JIT) inventory management.

Each of these methods has its own pros and cons, so it’s important to choose the one that will work best for your business.

  1. FIFO – FIFO means that the business takes the first inventory that it received and uses that as the basis of its inventory. When you sell a product, you use the oldest one in stock to calculate your sales. This method is great because it allows businesses to focus on selling older items first.
    For example, is a good choice for businesses that have perishable items in their inventory as it ensures that these items are used before they go bad.
  2. LIFO – LIFO inventory control is similar to FIFO, but instead it focuses on using the last item that was received as a basis for your inventory. It is often used by businesses that want to minimize their taxes as it results in lower costs being reported on their income statement.
  3. JIT Inventory Management – The JIT system also focuses on taking inventory from what has been received most recently, but this type of method also allows businesses to focus on ordering only what they need when they need it and nothing more. JIT inventory management is a popular choice for businesses that want to reduce their inventory levels and associated costs. This method involves only ordering stock as it’s needed, which can help to avoid the issue of overstocking.

No matter which method the organizations choose, it’s important to monitor the inventory levels closely and make adjustments as needed. Doing so will help to avoid stock outs and minimize the amount of money the company spends on its inventory.


Inventory management is a process that involves planning, controlling and organizing inventory in a way that optimizes a company’s warehouse operations. It is important because it helps companies keep track of their inventory, avoid stock-outs and prevent overstocking.

An effective inventory management system is important in a company’s strategies to increase sales, improve customer service levels, keep product quality high and reduce costs.

It can be used as a competitive advantage by companies that are able to have their products available for sale when customers want them and at the prices they offer.
