The Real Problem with Reorder Levels
Static reorder numbers cause two losses: stockouts for fast movers and overstock for slow movers. Reorder logic must be tied to actual demand and supplier behavior.
Practical Formula
Reorder Level = (Average Daily Sales × Lead Time in Days) + Safety Stock
Example: 12 units/day × 5 days + 20 safety stock = 80 units.
Setup Framework
- Classify SKUs into fast, medium, and slow movement.
- Calculate rolling 30-day average consumption.
- Record supplier lead time by category.
- Set safety stock based on volatility and supplier reliability.
Weekly Improvements
- Review fast movers every 30 days.
- Apply seasonality uplift before festivals and local peaks.
- Separate promotional demand from baseline demand.
- Track vendor fill-rate and delay trend.
When reorder levels evolve with data, shelf availability improves and emergency purchasing drops.
