The Three Main Inventory Management Techniques
Just-In-Time Inventory (JIT)
JIT is when Inventory orders are aligned closely with production schedules, meaning materials arrive just as they are needed.
Benefits: This method minimizes storage costs and reduces waste because inventory is not sitting idle for long periods.
It also ensures resources are used exactly when needed, which can improve production efficiency.
Challenges: Requires accurate demand forecasting and reliable suppliers.
Any delays in supply chain logistics can disrupt the entire production process, potentially resulting in stockouts and delayed customer deliveries.
Economic Order Quantity (EOQ)
EOQ calculates the optimal order quantity that minimizes total inventory costs, including ordering and holding costs.
Benefits: EOQ effectively balances ordering and holding costs, ensuring businesses do not spend excessively on either.
It also helps determine the most economical number of units to order, reducing unnecessary expenditures.
Challenges: Assumes constant demand and lead time, which may not be realistic for all businesses.
Variability in market conditions can affect the applicability of EOQ, requiring adjustments and more dynamic models in certain environments.
ABC Analysis
ABC analysis approach divides inventory into three categories (A, B, and C) based on importance: ‘ A’ items are the most valuable, ‘B’ items are moderately important, and ‘C’ items are the least valuable.
Benefits: Helps prioritize management efforts on the most critical inventory items.
By focusing on the most valuable items, businesses can ensure their key products are always available, maximizing profitability and efficiency.
Challenges: Requires regular review and adjustment based on changing business conditions.
As market demands and trends shift, the categorization of items might change, necessitating continuous monitoring and reclassification of inventory.
Other Inventory Management Strategies You Need to Know
Take a look at these other inventory management methods you can also use.
Safety Stock Inventory
Safety stock inventory is a buffer of additional stock kept on hand to mitigate the risk of stockouts caused by unpredictable demand or supply chain disruptions.
It ensures that a business can meet customer orders despite delays in replenishment.
FIFO: First In, First Out
FIFO is an inventory management technique in which the oldest inventory items are sold or used first.
This method helps reduce waste and spoilage, especially for perishable goods and aligns the cost of goods sold with current market prices.
LIFO: Last In, First Out
LIFO is an inventory management technique where the most recently acquired items are sold or used first.
This method can be beneficial during periods of inflation, as it matches recent higher costs with current revenues, potentially reducing taxable income.
Perpetual Inventory Management
A perpetual inventory system continuously updates inventory records to reflect sales and purchases in real time.
This system provides immediate visibility into stock levels, helping businesses make informed decisions and maintain optimal inventory levels.
Periodic Inventory System
A periodic inventory system updates inventory records at specified intervals, such as monthly or quarterly.
During these intervals, physical counts are conducted to determine stock levels, which can be less resource-intensive but may result in less accurate data between counts.
Batch Tracking
Batch tracking is managing inventory by monitoring groups of products with common characteristics or production dates.
This technique is essential for traceability, quality control, and managing product recalls, ensuring that specific batches can be identified and managed effectively.
Consignment Inventory
Consignment inventory involves storing goods at the retailer’s location without the retailer having to purchase them upfront.
The supplier retains ownership until the products are sold, reducing the retailer’s financial risk and encouraging more product stocking.
Dropshipping
Dropshipping is a retail fulfillment method where the seller does not keep products in stock but instead transfers customer orders directly to the manufacturer or wholesaler, who then ships the goods directly to the customer.
This model reduces overhead costs and eliminates the need for inventory storage.
Vendor-Managed Inventory (VMI)
Vendor-managed inventory is a strategy where the supplier takes responsibility for maintaining the inventory levels of their products at the customer’s location.
This approach improves supply chain efficiency, reduces stockouts, and optimizes inventory turnover by leveraging the supplier’s expertise and resources.
How Can Inventory Management Improve Cost Effectiveness?
