What is Inventory Control? Types, Functions and Methods

Inventory control refers to the management and regulation of goods or materials within a business, from the time they are received to the time they are sold or consumed. This process involves tracking inventory levels, monitoring their movement, and optimizing storage and usage to ensure efficient operations and maximize profitability.

Effective Inventory Control is crucial for businesses, as it allows them to meet customer demand, avoid stockouts, reduce holding costs, and prevent wastage. By optimizing inventory management, businesses can ensure that they have the right amount of inventory at the right time and place, reduce the risk of overstocking or stockouts, and streamline their operations.

There are several types of inventory control that businesses can use to manage their inventory effectively. One of the most common methods is ABC analysis, which categorizes inventory based on their value and usage. This method helps businesses prioritize critical items, ensure that they are always available when needed, and optimize storage and usage for other items.

Another popular inventory control method is Just-in-Time (JIT) inventory, which involves ordering inventory only when needed. JIT inventory helps businesses maintain a lean inventory, reduce storage costs, and avoid overstocking or wastage.

Other inventory control methods include Economic Order Quantity (EOQ), Material Requirements Planning (MRP), and safety stock. EOQ calculates the optimal order quantity based on the demand, cost, and storage expenses, while MRP uses software to manage inventory levels based on production schedules and demand forecasts. Safety stock, on the other hand, involves maintaining extra inventory to prevent stockouts and meet unexpected demand.

Inventory control also has several functions, including stock monitoring, order management, stock movement, and stock valuation. By monitoring inventory levels, businesses can ensure that they have enough inventory to meet demand while avoiding overstocking. Effective order management ensures that orders are processed efficiently and accurately, while stock movement involves tracking inventory as it moves through the supply chain. Finally, stock valuation involves determining the value of inventory, which is crucial for financial reporting and decision-making.

However, inventory control also presents several challenges for businesses, such as forecasting demand, managing lead times, managing multiple inventory locations, balancing inventory costs, managing inventory accuracy, managing obsolete inventory, and implementing effective inventory control systems. Businesses must adopt best practices and strategies to address these challenges, such as implementing robust inventory management software, optimizing supply chain logistics, using data analytics to forecast demand, and implementing effective inventory control policies.

Definition Of Inventory Control

Inventory control is a vital process in business management that involves managing and regulating the movement of goods or materials from their reception to their consumption or sale. The inventory control process entails closely monitoring and tracking inventory levels, as well as implementing various techniques and strategies aimed at optimizing inventory management. This includes minimizing stockouts, reducing holding costs, and improving customer service to achieve effective inventory control.

For businesses, effective inventory control is crucial as it plays a significant role in ensuring efficient operations, meeting customer demand, and maximizing profitability. By keeping track of inventory levels, businesses can determine how much inventory they have at any given time, which can help them avoid stockouts and ensure that they have enough inventory on hand to meet customer demands. Additionally, optimizing inventory management can help businesses reduce holding costs, minimize waste and spoilage, and improve overall customer service.

To achieve effective inventory control, businesses can adopt various types of inventory control methods, such as ABC analysis, Just-in-Time inventory, Economic Order Quantity (EOQ), Material Requirements Planning (MRP), and safety stock. Each of these methods of inventory control is designed to help businesses manage inventory efficiently and effectively.

Importance Of Inventory Control For Businesses

Inventory control is vital for businesses for the following reasons:

Meeting Customer Demand:

Having the right amount of inventory on hand ensures that businesses can fulfill customer orders promptly, thereby improving customer satisfaction and loyalty.

Reducing Costs:

Proper inventory control can help businesses minimize holding costs, such as storage, insurance, and taxes, and reduce the risk of excess inventory becoming obsolete or deteriorating.

Improving Cash Flow:

By managing inventory levels, businesses can avoid overstocking and tie-ups of working capital, enabling them to allocate resources more efficiently.

Enhancing Operations Efficiency:

Effective inventory control allows businesses to streamline their supply chain management processes, reduce lead times, and optimize production schedules.

Preventing Losses:

Inventory control can help prevent losses due to theft, damage, or spoilage of goods, which can be costly to replace and harm the business’s reputation.

Types of Inventory Control

There are two main types of inventory control: perpetual inventory control and periodic inventory control.

Perpetual Inventory Control:

In perpetual inventory control, the inventory is continuously monitored and tracked, and the inventory levels are updated in real-time as soon as a transaction occurs. This is usually done through the use of technology such as barcodes or RFID tags, which enables businesses to track inventory levels accurately and efficiently.
Perpetual inventory control allows businesses to have up-to-date information on inventory levels, making it easier to manage inventory levels, identify potential stockouts or overstocks, and ensure timely replenishment of inventory.

Periodic Inventory Control:

In periodic inventory control, the inventory levels are checked periodically, typically at the end of a specific period such as a week, month, or quarter. The inventory count is done manually, and the inventory levels are adjusted accordingly.
Periodic inventory control is less accurate than perpetual inventory control, as it relies on manual inventory counts, which can be prone to errors. However, it is still useful for businesses that have low transaction volumes or deal with non-perishable items, where accurate inventory tracking is less critical.

In summary, the choice of inventory control method depends on the type of business, the volume of transactions, the nature of the goods, and the available resources. While perpetual inventory control provides more accurate inventory tracking, periodic inventory control can still be effective for businesses with lower transaction volumes or non-perishable items.

Functions of Inventory Control

The primary functions of inventory control are as follows:

Ensuring Adequate Stock Levels:

Inventory control ensures that businesses maintain optimal inventory levels to meet customer demand without overstocking, which can lead to excess holding costs.

Reducing Inventory Holding Costs:

By maintaining optimal inventory levels, businesses can reduce holding costs such as storage, insurance, and taxes.

Preventing Stockouts and Overstocking:

Inventory control helps prevent stockouts, which can result in lost sales and dissatisfied customers, and overstocking, which can lead to excess holding costs and obsolete inventory.

Minimizing the Risk of Theft and Damage:

Inventory control can help prevent losses due to theft, damage, or spoilage of goods, which can be costly to replace and harm the business’s reputation.

Improving Customer Service:

By ensuring adequate inventory levels and preventing stockouts, inventory control can help improve customer satisfaction and loyalty.

Methods of Inventory Control

There are several methods of inventory control that businesses can use to optimize their inventory management:

ABC Analysis:

ABC analysis involves classifying inventory items into categories based on their value, with A items being high-value items that require close monitoring, B items being moderate-value items that require some monitoring, and C items being low-value items that require minimal monitoring. This method allows businesses to prioritize inventory management efforts and allocate resources accordingly.

Just-in-Time (JIT) Inventory:

JIT inventory involves ordering inventory only when it is needed, rather than keeping large stockpiles on hand. This method can help reduce holding costs and optimize inventory levels, but it requires close coordination with suppliers and can be risky if there are unexpected supply chain disruptions.

Economic Order Quantity (EOQ):

EOQ is a mathematical formula that calculates the optimal order quantity for a given item based on the cost of ordering, holding, and carrying inventory. This method allows businesses to balance the cost of holding inventory against the cost of ordering and can help optimize inventory levels and minimize holding costs.

Material Requirements Planning (MRP):

MRP is a computer-based system that uses forecasting and scheduling to determine the optimal inventory levels and production schedules. This method can help businesses optimize inventory levels and streamline production processes.

Safety Stock:

Safety stock involves keeping a buffer of inventory on hand to account for unexpected fluctuations in demand or supply chain disruptions. This method can help prevent stockouts and improve customer service, but it also increases holding costs.

Benefits of Effective Inventory Control

Effective inventory control can provide several benefits to businesses, including:

Improved Efficiency: By optimizing inventory levels and reducing stockouts, businesses can operate more efficiently and effectively.

Lower Holding Costs: Effective inventory control can help reduce holding costs such as storage, insurance, and taxes by minimizing excess inventory.

Increased Profitability: By optimizing inventory levels and reducing holding costs, businesses can increase their profitability.
