A reorder point is a decision threshold, not merely a low-stock alert. It should reflect how quickly an item moves, how long replenishment takes and how costly a shortage would be for the business.
Start with usable availability
On-hand quantity alone can mislead. Review stock by location alongside committed demand, incoming purchases, transfers and quantities that cannot be sold because of quality or expiry concerns.
Use one consistent unit of measure when comparing demand and availability, especially where goods are purchased in cases and sold as individual pieces.
Include lead time and variability
Estimate normal demand during the supplier lead time, then add a deliberate safety quantity for variability. The buffer should be larger when demand or delivery is unpredictable and smaller when replenishment is fast and dependable.
- Review supplier delivery history rather than quoted lead time alone.
- Separate seasonal items from stable everyday demand.
- Flag critical items whose shortage stops sales or production.
Review exceptions, not every item equally
Use reorder reports to focus attention on items below their threshold, unusually slow stock and incoming supply that is already late. This keeps purchasing work directed toward decisions instead of scanning an entire catalogue.
Revisit thresholds after promotions, supplier changes, new locations or material changes in demand.
