Managing inventory is balancing two risks: **Stockout** (missing product, losing sales) and **Excess** (cash tied up on the shelf). The simple rule "when it hits 10, buy more" ignores seasonality and supplier Lead Time.

### **The Safety Stock Formula**

You need to calculate:

- Average Daily Consumption.
- Consumption Variation (Standard Deviation).
- Supplier Lead Time.

### **Inventory Intelligence in Jestor**

This is where Jestor stands out by delivering the solution in practice:
