Top Inventory Management Techniques & Methods for Success

Have you ever wondered why your business can be doing everything right and still end up with stockouts or piles of unsold goods? Well, it’s all about how you manage your inventory. 

Here, we’ll explore various methods to help you optimize your inventory management process and solve your stock problems once and for all. Implementing the best inventory management techniques & methods is the key to turning a good business into a great one. In fact, it directly impacts your profitability, efficiency, and customer satisfaction. 

What is Inventory Management?

At its core, inventory management is about making sure the right products are available at the right time, in the right quantity, and at the right cost. It is the process of overseeing the flow of goods from manufacturers to warehouses and ultimately, to the point of sale.

Part of inventory management is that businesses should optimize stock levels and ensure timely replenishment so that:

• Operations run smoothly.
• Customer demand is met.
• Costs are kept under control. 

This ensures that your business doesn’t run into issues like stockouts or wasteful overstocking, as well as missed opportunities. 

And because proper inventory management has a direct impact on your business, it acts as one of the backbones of your business’s ability to grow and succeed.

Inventory Management Techniques

Now, let’s take a look at some of the common and widely used methods you can use to manage your inventory more effectively.

Just-in-Time (JIT) Inventory

Just-in-time (JIT) inventory helps reduce stock levels by receiving goods only when they are needed for production or to fulfill customer orders. 

The idea here is to keep inventory levels low, cut storage costs, and reduce waste. This method improves stock efficiency by making sure you’re not sitting on piles of unsold stock.

However, JIT isn’t without its risks. For example, a disruption in your supply chain could leave you without the products you need at a critical moment. But when it works, it can reduce excess inventory and keep your warehouse more organized.

ABC Analysis

Another method is the ABC analysis, which helps you categorize your inventory based on value and turnover. Think of it as a way to prioritize your stock into three categories:

• A items: high-value, low-quantity (e.g., luxury items)
• B items: moderate value, moderate quantity
• C items: low-value, high-quantity (e.g., fast-moving consumer goods)

This way, you can focus on the most valuable items and make sure that they are always stocked in sufficient quantities, while still keeping an eye on the less critical goods. 

This technique supports demand forecasting as it shows you which items are more important and which ones can wait a little longer.

Economic Order Quantity (EOQ)

If you want to figure out the optimal order size to minimize ordering and holding costs, use the economic order quantity (EOQ) formula, so you can control the reordering process without spending too much on excess inventory.

EOQ Formula:

EOQ = √(2DS / H)

Where:

• D = Demand (units per year)
• S = Ordering cost per order
• H = Holding cost per unit per year

EOQ helps you balance holding costs and availability, so you get stock levels that are aligned with demand.

Cycle Counting

On the other hand, cycle counting is the systematic process of keeping track of inventory without full physical counts. Here, you check small portions of your stock periodically instead of shutting down operations for bigger counts.

Cycle counting is a continuous process that enables real-time tracking and helps you adjust stock levels before things get out of hand.

Safety Stock

Now, safety stock is the buffer or extra inventory you keep on hand to handle unexpected demand surges or supply delays. 

To calculate the safety stock quantity:

Safety Stock = (Maximum Daily Demand x Maximum Lead Time) – (Average Daily Demand x Average Lead Time)

Monitor safety stock levels to avoid tying up unnecessary cash in goods you don’t need.

Reorder Point Formula

Next, the reorder point formula determines the exact moment when you should reorder products before running out so there’s never a delay in fulfilling customer orders.

Formula:

Reorder Point = Lead Time Demand

Where:

• Lead Time Demand = Average demand per period × Lead time in periods

Knowing when to reorder gives you the confidence that you won’t run out of stock at the worst possible moment.

Perpetual Inventory System

If you’re looking for a more automated solution, a perpetual inventory system can help you keep tabs on every movement of your goods. 

Examples of inventory tracking systems include:

• Barcodes
• RFIDs

This responsive method allows you to track your goods in real time, and it also integrates with warehouse management systems like ShipHero for seamless inventory control. That way, you get to adjust inventory based on demand and make smarter decisions about stock replenishment.

Materials Requirements Planning (MRP)

Lastly, Materials Requirements Planning (MRP) is a dynamic software system used primarily for manufacturing processes. 

For example, a furniture company uses MRP to plan production schedules and track the materials needed for each order. The software calculates the quantity of raw materials required, like wood, screws, and upholstery, based on the number of pieces to be produced. 

If the company’s stock of wood falls below the required level for an upcoming order, MRP generates a purchase order to replenish the stock before production begins. 

MRP ensures that raw materials and components are available for production without overstocking. 

Advanced Inventory Management Methods

Now, when your business starts scaling up, consider more advanced methods for managing inventory. These techniques are often used by larger businesses or those with specialized inventory needs.

Method	Description
First In, First Out (FIFO)	Ensures that the first products you receive are the first to be sold or used; useful when dealing with perishable goods or items that can quickly become obsolete.
Last-In, First-Out (LIFO)	Opposite of FIFO, where the most recent inventory is sold first; beneficial in industries where inventory costs are rising.
Vendor-Managed Inventory (VMI)	Allows suppliers to manage the stock at your location, reducing the workload for your team and ensuring stock is always available without constant monitoring.
Weighted Average Cost (WAC)	An inventory valuation method used for interchangeable products, where the cost of all stock is averaged for easier accounting.
Specific Identification	Tracks each item individually, often used for high-value goods like luxury items or automobiles; allows for precise tracking but can be challenging for large inventories.

 

How to Choose the Right Inventory Management Technique

The ideal inventory management technique depends on your company’s size, industry, and specific inventory needs. Key factors to consider include:

• Product type
• Sales volume
• Supply chain complexity
• Business goals

In many cases, using a combination of methods works best. You might use ABC analysis to categorize your products, while also using JIT to manage high-turnover items and safety stock for more unpredictable demand. 

Such a hybrid approach lets you adapt and meet customer demand without facing shortages, as well as create a scalable inventory management process for your business.

Best Practices for Inventory Management Success

Lastly, follow these tips to ensure long-term success:

• Use accurate data and forecasting to predict demand and adjust inventory strategies accordingly. 
• Perform regular stock checks to ensure accurate inventory records.
• Build strong relationships with suppliers for better pricing and timely stock replenishment.
• Improve your warehouse design to streamline the movement of goods and reduce handling costs to maximize space utilization.
• Track key performance indicators (KPIs) like inventory turnover and order accuracy.
• Stay flexible and adapt to market trends, technological changes, and shifts in customer demand.

Inventory management is the heart of your business’s ability to stay competitive, reduce costs, and meet customer needs. Without it, even the best strategies and products can fall short. 

Optimize your inventory management today, and you’ll see the difference.
