Keeping customers happy means keeping product in stock — but that’s easier said than done. 

Managing supplier relationships, navigating supply chain risks, and streamlining warehouse operations are just a few factors that impact stock levels. And balancing all of these elements requires knowing what the ideal inventory levels are for your operation. Keeping that much stock on hand — without going over or under — is known as optimizing your inventory. 

Whether you’re new to managing stock or looking to improve your current processes, here’s a guide to inventory optimization to help determine what stock levels you need to maintain for maximum profitability and efficiency.

What is inventory optimization?

Optimizing your inventory means having the right amount of stock available where you need it, when you need it. Here are the elements that work together to guarantee you maintain that sweet spot:

  • Demand forecasting: By analyzing historical sales data, market trends, and statistical models, you can predict future demand to improve the accuracy of sales predictions.
  • Safety stock: Having safety stock on hand provides a buffer inventory to handle unexpected demand spikes or supply chain disruptions, ensuring product availability to keep customers happy. The right safety stock level depends on factors like demand variability and lead time. 
  • Reorder point calculation: Calculating the reorder point determines the optimal time to restock inventory, preventing the occurrence of stockouts or overstocking. Plus, you’ll save on carrying costs (the cost of storing inventory) and reduce the risk of accumulating damaged or unsellable goods. Consider the lead time, average daily sales, and ideal safety stock levels to set optimal reorder points.
  • Inventory turnover: Monitoring inventory turnover offers valuable insights into how quickly stock moves. High turnover indicates efficient sales, while low turnover may suggest overstocking or slow-moving SKUs. By monitoring your turnover ratio, you can discover valuable trends to fine-tune stock levels and boost operational efficiency.
  • Inventory planning: A successful inventory plan requires effective reordering and product management decisions. All of these elements work together to improve operations and save money.

The benefits of inventory optimization

Here are the advantages of gaining control over your inventory

  • Cost reduction: Lower your expenses associated with storing inventory, like rent, utilities, and personnel, by reducing the insurance and tax costs related to excess inventory.
  • Improved cash flow: Effectively managing inventory levels enhances your cash flow by freeing up working capital, which you can allocate to other business needs or growth opportunities.
  • Enhanced customer satisfaction: Maintaining consistent product availability can help you meet customer demand more effectively, increasing customer satisfaction and long-term loyalty.
  • Operational efficiency: Streamline inventory processes for better resource utilization and a more efficient supply chain management system.

7 inventory optimization techniques to try

Here are seven popular inventory optimization techniques that help you effectively manage your inventory:

1. Just-in-Time inventory

With a Just-in-Time (JIT) inventory strategy, companies order and receive materials exactly when they’re needed for production or sales, which reduces carrying costs and minimizes excess inventory. This method requires close coordination with suppliers and a reliable supply chain.

2. ABC analysis

An ABC analysis categorizes inventory items into three groups based on their importance: A (high value), B (moderate value), and C (low value). By identifying and prioritizing high-value items, businesses can optimize inventory management to improve profitability.

3. Economic Order Quantity 

Economic order quantity (EOQ) is a formula used to determine the optimal order quantity to minimize the total costs of ordering and holding inventory. Balancing this with your reorder points helps you keep the optimal amount of stock on hand without requiring constant replenishment.

4. Safety stock inventory

Regularly reviewing and adjusting safety stock levels can help maintain optimal inventory and service levels. It also protects you from running out of goods during supply chain disruptions or changes in demand.

5. Demand forecasting

To predict future demand, analyze past sales data, market trends, seasonal variations, and other relevant factors like promotions or competitor actions. This information helps you plan inventory levels more accurately.

6. Vendor-managed inventory

Vendor-managed inventory (VMI) is a collaborative approach where suppliers manage their customers’ inventory levels based on agreed-upon criteria. This technique improves supply chain efficiency to ensure timely replenishment and maintain high service levels.

7. Automated replenishment system

Automated systems use real-time data and algorithms to automatically trigger reorder points and quantities. This reduces manual intervention, which improves accuracy and stock replenishment practices.

Best practices for effective inventory optimization

To get the most out of inventory optimization, follow these best practices:

  1. Implement real-time inventory tracking across locations: Use inventory management software to monitor levels across multiple locations to access accurate, up-to-date information about stock levels. With this knowledge, you can allocate inventory to optimize distribution. 
  2. Optimize reorder points and quantities: Regularly review and adjust reorder points and quantities based on demand patterns and lead times to ensure inventory levels always match actual needs.
  3. Leverage technology and automation: Use automation wherever possible to streamline processes, reduce errors, and boost efficiency. Advanced automated inventory systems can offer insights and recommendations on optimizing inventory and improving control.
  4. Enhance supplier relationships: Work closely to improve relationships with suppliers to shorten lead times, maintain consistent quality, and negotiate favorable purchasing terms. 
  5. Conduct regular inventory audits: Conduct audits to overcome inventory inefficiency, keep inventory records accurate, and identify discrepancies, ensuring reliable and up-to-date data.
