What is Inventory Control – Meaning, Importance & Techniques

blog

Inventory control means keeping track of stock levels and managing how much of each product a business holds. It helps a company know what it has, what it needs, and when to order more.

Let’s say a small toy shop sells board games. If it doesn't track how many games are left, it might run out just before a holiday rush or end up with too many that go unsold. With inventory control, the shop checks stock regularly, knows what sells fast, and restocks just in time.

Here’s a simple example:
 

Product

Current Stock

Average Monthly Sales

Action Needed

Chess Set

3 units

10 units

Order more stock

Puzzle (1000 pc)

12 units

4 units

Stock is sufficient

Card Game Pack

0 units

6 units

Restock immediately

 

This process avoids overstocking and understocking. It also helps prevent loss due to theft or damage. With the right stock at the right time, businesses improve customer satisfaction and increase profits.

Why Inventory Control Matters in Business?

Inventory control means keeping the right amount of stock, not too much and not too little. It’s important because stock takes up a big part of a company’s money. If you check a product-based company’s balance sheet, you’ll often see inventory listed as one of the largest current assets.

Good inventory control helps in two ways:
 

  • It stops money from being stuck in extra stock.
     
  • It ensures you never run out of what you need.
     

Even companies that use just-in-time (JIT) ordering systems still need some form of inventory control to keep operations smooth.

How Inventory Control Affects Business Performance
 

Scenario

Inventory Control Result

Business Impact

Too much stock

Reduces waste and storage costs

Frees up cash for growth

Too little stock

Avoids lost sales and customer delays

Increases customer satisfaction

Balanced stock with control

Matches supply with demand

Improves profits and efficiency


Example:

A mobile shop holds ₹10,00,000 in inventory but only sells ₹6,00,000 worth in a month. ₹4,00,000 is stuck in unused stock. With inventory control, they cut stock to ₹7,00,000, free ₹3,00,000 for marketing or expansion, and still meet customer demand.

Using inventory control wisely helps any business lower costs, avoid waste, improve cash flow, and increase profits, all while keeping customers happy.

How Shops Keep Track of Stock

Every shop needs to know how many items it has, what is sold, and what needs to be bought again. Here is a simple table that shows five easy ways to track stock.

Method

What It Is

How It Works

Good For

Important to Know

Periodic Inventory System

Counting your stock from time to time

You do a physical count and update records at set times

Small shops with fewer products

Work stops during counting. You might miss stolen or broken items

Perpetual Inventory System

Always updating stock using computers

Every sale or purchase updates the system right away

Busy shops with lots of stock

You still need to check physical stock sometimes to make sure it matches

Barcodes

A label with black lines that stores product information

You scan the barcode with a scanner to track stock

Shops that want quick and simple updates

Needs a scanner. Saves time and reduces mistakes

RFID Tags

A smart label that talks to the system using radio waves

The tag sends updates automatically, even from a distance

High-value or sensitive stock

More expensive. Great for security. Some tags need batteries, some do not

QR Codes

A square image that stores more details than a barcode

Scan it with a phone or tablet app to see item details

Small shops want cheaper solutions

No scanner needed. Very easy to use. Holds more info than barcodes


Every shop or business can pick the method that suits its size, budget and needs. Small shops may use QR codes or do manual counts. Bigger shops may use barcodes or RFID tags. The best system helps you stay organised and avoid running out of stock.

What Are Inventory Control Methods?

Inventory control methods are ways that businesses decide how much stock to keep, how much to order, when to sell, and how much to store. These methods use the company’s skills, planning tools, and customer needs to help make the right choices.

Good inventory control helps a business:
 

  • Save money by not buying or keeping too much stock
     
  • Make sure products are always ready when customers want them
     
  • Use warehouse space wisely
     
  • Avoid waste or items going out of date
     

Why Inventory Control Matters?

When a company holds too much stock for too long, it uses up money and space. To measure this, businesses use something called Days of Inventory Outstanding (DIO). DIO shows how many days, on average, a business keeps stock before it sells it.

A lower DIO is better, because it means:
 

  • The stock moves quickly
     
  • The business is not wasting money on storage
     
  • There is less risk of damage or loss
     

In recent years, DIO numbers have gone up, which means businesses are keeping stock longer. This can increase warehouse costs and reduce profits. That is why strong inventory control is important. It helps businesses sell items faster and avoid extra costs.


Conclusion


Inventory control helps a business keep the right amount of stock at the right time. It saves money, avoids waste, and keeps customers happy. By planning and checking stock properly, a business can run smoothly and grow with fewer problems.
