Inventory is the biggest asset on a retailer's balance sheet and the biggest source of waste. Too much stock ties up cash and leads to markdowns. Too little loses sales and frustrates customers.
The science of inventory optimization has been around for decades, but most growing retailers don't use it because the concepts sound intimidating: safety stock, reorder points, service levels, lead time variability.
The Basics, Simply
ABC Analysis: Not all products deserve the same attention. Your A items (top 20% of revenue) need daily monitoring. Your C items (bottom 50%) can be checked monthly. This alone reduces workload by 60%.
Reorder Point: The stock level at which you should place a new order. It's: (average daily sales × lead time) + safety stock. That's it.
Safety Stock: Extra inventory to cover variability. Higher for unpredictable products, lower for steady sellers. The formula considers both demand variability and supplier reliability.
Why AI Helps
These calculations are simple individually but complex at scale. A retailer with 2,000 SKUs across 4 stores needs 8,000 reorder points, each updated as demand patterns shift. An agent recalculates continuously — a human does it quarterly at best.
