Inventory management is crucial for companies to maintain profitability and meet customer demand. Proper inventory practices like just-in-time inventory and economic order quantity models balance the costs and benefits of holding inventory. By optimizing inventory levels, companies can reduce costs related to storage, spoilage and obsolescence while avoiding expensive stock-outs. This article will analyze real-world inventory examples to illustrate best practices for managing inventory investments.

Using just-in-time inventory to cut holding costs
Just-in-time (JIT) inventory management keeps stock levels low by coordinating orders closely with production schedules and customer demand. Companies like Toyota use JIT to reduce inventory carrying costs. For example, Toyota relies on frequent deliveries of small parts batches to maintain lean buffers between workstations. This cuts inventory storage needs and waste from overproduction. JIT requires excellent supply chain communication and logistics to avoid stock-outs from variability or delays.
Applying economic order quantity models
The economic order quantity (EOQ) model determines the optimal reorder quantity by balancing inventory holding costs against order placement costs. Companies set a fixed reorder point and order size to minimize total inventory costs. For example, a retailer may optimize profitability by ordering $5,000 of product every time stock falls to $1,000 on hand. The EOQ framework helps companies scientifically determine ideal order sizes.
Using technology to improve inventory tracking
Information technology like barcode scanners and inventory management software provides companies real-time visibility into stock levels. This enhances planning and helps avoid costly stock-outs or excesses. For instance, leveraging perpetual inventory systems, retailers can view sales activity and remaining inventory across multiple locations. Advanced analytics also help predict optimal stock levels based on sales history and trends.
Centralizing inventories in distribution centers
Companies can reduce inventory costs by consolidating stock in centralized distribution centers rather than dispersed locations. For example, retailers operate regional warehouses to aggregate inventory for multiple stores. This cuts duplication at individual outlets and facilitates cost-efficient transportation. Centralization requires excellent logistics and freight management to ensure timely stock availability.
Effective inventory management optimizes companies’ working capital investment in stock while avoiding expensive stock-outs. Models like JIT and EOQ combined with technologies like perpetual inventory systems help firms systematically balance the costs and benefits of inventory holdings.
