Understanding  Inventory Control

Inventory control (also known as stock control) is a process of managing and tracking the items that a business intends to sell. It involves various policies, procedures, and techniques to ensure optimal levels of inventory to meet customer demand while minimizing costs. Effective inventory control is necessary for businesses of all sizes and industries to maintain profitability, reduce waste and spoilage, and improve customer satisfaction.

In this article, we will explore the basics of inventory control by answering the seven most popular questions about this topic.

What is Inventory Control?

Inventory control is a process that allows businesses to manage their inventory levels effectively. It includes several tasks, such as demand forecasting, setting reorder points, safety stock management, and ABC analysis. The ultimate goal of inventory control is to balance the costs associated with holding inventory against the costs of stockouts or shortages.

Why is Inventory Control Important?

Effective inventory control provides several benefits for businesses:

  • Reduced Costs: By optimizing inventory levels and avoiding overstocking or stockouts, businesses can reduce storage costs, prevent spoilage and obsolescence, minimize write-offs or losses from theft or damage.
  • Improved Efficiency: With accurate tracking and management of inventories, businesses can reduce lead times, improve order fulfilment rates and on-time delivery rates.
  • Enhanced Customer Service: By maintaining optimal stock levels at all times, businesses can meet customer demand consistently without delays or backorders.
  • Better Decision Making: With continuous monitoring of inventory data and forecasting tools at hand, businesses can make informed decisions about purchasing strategies, product promotions or discounts.

What are the Strategies for Effective Inventory Control?

Here are some strategies that businesses can adopt for effective inventory control:

  • Demand Forecasting: Accurately predicting future demand helps businesses determine how much stock they need to hold at any given time.
  • Reorder Point: The minimum level of inventory that triggers a reorder helps businesses avoid stockouts and maintain optimal inventory levels.
  • Safety Stock: Extra inventory held in reserve to handle unexpected demand, supply chain disruptions, or lead time variability.
  • ABC Analysis: A method of classifying inventory items based on their value, frequency of demand, and availability. It helps businesses prioritize their inventory management efforts effectively.
  • Inventory Audits: Regular physical counts of inventory help businesses identify discrepancies, root causes, and opportunities for improvement.

How to Calculate Economic Order Quantity (EOQ)?

Economic Order Quantity (EOQ) is the optimal quantity of goods to order at one time to minimize both ordering costs and holding costs. The formula for EOQ is:

EOQ = √ [(2 x Annual Demand x Ordering Cost)/Holding Cost per Unit]

What is the Role of Technology in Inventory Control?

Technology plays a critical role in automating and streamlining inventory control processes. Inventory management software offers various features such as real-time tracking, demand forecasting analytics, barcode scanning, automatic order generation, and alerts for low stock levels.

What are the Common Challenges in Inventory Control?

Some common challenges that businesses face in inventory control include inaccurate forecasting, stockouts or overstocking issues, inefficient replenishment processes, lack of visibility into supply chain partners' inventories or lead times.
