Inventory Optimization: Key Concepts and Practice

What Is Inventory Optimization?

Inventory optimization is the practice of determining the ideal quantity of each SKU to hold at each location at any given time. The goal is to hit customer service level targets while minimizing the costs of holding too much inventory (carrying costs, obsolescence, storage) and the costs of holding too little (stockouts, expedited shipping, lost revenue).

For product businesses managing multiple SKUs across multiple locations, true inventory optimization is not a spreadsheet exercise. It requires dynamic calculations across:

Frequently Asked Questions

What is the difference between inventory optimization and inventory management?

Inventory management is the operational practice of tracking and moving inventory. Inventory optimization is the analytical layer that determines what levels to target. Management is the execution; optimization is the strategy behind it.

How do you measure inventory optimization performance?

Common metrics include inventory turnover ratio, days of inventory outstanding (DIO), fill rate, stockout frequency, and carrying cost as a percentage of revenue. Improvement in these metrics over time signals better optimization.

What causes inventory imbalance across locations?

Uneven demand patterns, inaccurate location-level forecasts, slow replenishment from suppliers, and lack of inter-location transfer logic. Systems that do not have a unified view across all locations cannot optimize across them.
