What are the Best Practices in Inventory Management? Key Best Practices

What Is Inventory Control?

Inventory management, also called stock management, is the crucial process of maintaining optimal supply levels within an organization. 

By implementing effective internal and production controls, this practice ensures that companies can fulfill customer demand while maintaining financial flexibility.

Achieving successful inventory management involves gathering data from various facets such as purchases, reorders, shipping, warehousing, storage, receiving, customer satisfaction, loss prevention, and turnover. 

According to the "State of Small Business Report" findings in 2017, nearly half of small businesses fail to track their inventory, even through manual methods.

Inventory management aims to maximize profit with minimal investment in stock, all while safeguarding customer satisfaction. 

When executed correctly, it enables companies to evaluate their current state regarding assets, account balances, and financial reports. Proper inventory control helps prevent issues like stockouts, which can lead to missed sales opportunities. For instance, inadequate inventory control procedures at Walmart resulted in an estimated $3 billion worth of missed sales in 2014.

An integral inventory control component is Supply Chain Management (SCM), which oversees the flow of raw materials, goods, and services from the source to the point of consumption by the company or its customers. 

Warehouse management is a key aspect of stock control, involving the integration of product coding, reorder points and reports, comprehensive product details, inventory lists and counts, and methods for selling or storing. Warehouse management synchronizes sales and purchases with the stock on hand.

While inventory control and management may appear interchangeable, they represent distinct concepts. Inventory control focuses on regulating existing warehouse stock, while inventory management encompasses the entire process of procuring, storing, and profiting from merchandise or services. 

The latter involves not only what is in the warehouse but also how the product reaches the business and ultimately reaches its final destination.

Effective inventory control practices and policies should extend beyond finished and raw goods. The accompanying graphic illustrates the diverse aspects of business management that can benefit from these practices.

Here are some of the key activities involved in inventory control:

• Tracking stock levels - This involves keeping track of the quantity of each item in stock, as well as its location.
• Forecasting demand - This involves estimating how much of each item will be sold in the future.
• Setting reorder points involves determining the level at which inventory needs to be reordered.
• Purchasing - This involves ordering the right amount of the right products at the right time.
• Receiving - This involves checking in inventory when it arrives and ensuring it is accurate.
• Storing - This involves storing inventory safely and efficiently.
• Issuing - This involves picking and packing inventory for customers or production.
• Taking inventory - This involves physically counting inventory levels to ensure accuracy.

Why Is Inventory Control Important?

Inventory control is crucial for businesses due to its significant impact on operational efficiency, financial stability, and customer satisfaction. One primary reason for its importance is optimizing the balance between supply and demand. 

Maintaining an accurate and well-regulated inventory ensures that a company has the right amount of stock available to meet customer needs without excess, preventing overstocking or stockouts. 

This equilibrium helps businesses minimize carrying costs, storage expenses, and potential losses due to perishable or obsolete items.

Secondly, effective inventory control plays a pivotal role in cash flow management. Businesses can allocate capital more efficiently by closely monitoring inventory levels and turnover. Excessive stock ties up funds that could be used elsewhere, while inadequate stock may lead to missed sales opportunities. 

Striking the right balance through inventory control allows businesses to release capital tied up in inventory, enabling them to invest in growth initiatives, technology upgrades, or other critical areas that contribute to long-term success.

Furthermore, inventory control enhances customer satisfaction and loyalty. Timely and accurate order fulfillment is directly linked to a company's ability to meet customer expectations. With efficient inventory management, businesses can reduce order processing times, avoid backorders, and ensure product availability. 

This reliability contributes to positive customer experiences, fosters repeat business, and strengthens the company's reputation in the market. 

Inventory control is vital for achieving operational efficiency, optimizing financial resources, and delivering a superior customer experience.

The Benefits of Inventory Management

 A company's inventory is one of its most valuable assets, particularly in retail, manufacturing, and food services sectors, where inputs and finished products form the core of operations. 

However, the significance of inventory is not without its challenges. An inventory shortage in crucial locations and times can severely affect a business. Conversely, holding a large inventory introduces potential risks such as spoilage, theft, damage, and shifts in demand. 

As both an asset and a liability, this dual nature of inventory underscores the importance of effective inventory management.

The benefits of robust inventory management are multifaceted. It ensures the timely availability of products, preventing stockouts that could harm customer satisfaction and sales. Moreover, proper inventory management minimizes carrying costs, insurance expenses, and the risk of perishable goods going to waste. 

Businesses can enhance their financial health by optimizing when to restock, determining appropriate quantities, and setting competitive prices.

Manual tracking and spreadsheet formulas often suffice for small businesses to manage inventory. On the other hand, larger enterprises leverage specialized enterprise resource planning (ERP) software to handle the complexities involved in decision-making regarding inventory. 

Regardless of size, businesses that implement effective inventory management practices gain a competitive edge by mitigating risks, improving operational efficiency, and maximizing the value of their crucial assets.

Inventory management examples: 

• Cuts Costs - Less storage, smarter buying, and fewer stockouts = money saved.
• Boosts Efficiency - Streamlined operations, better forecasting, and fewer errors = smooth workflows.
• Thrills Customers - Faster deliveries, happy availability, and stronger supplier ties = loyal fans.
• Empowers Decisions - Data insights guide pricing, promotions, and purchasing strategies.
• Reduces Risks - Less waste, minimized obsolescence, freed-up employees = a thriving business.

9 Efficient Inventory Management Strategies
