What Is Reorder Point?
Understand how the reorder point determines exactly when to place a new order so that inventory arrives before stock runs out.
Key Takeaways
- The reorder point is the inventory level at which a new purchase order should be placed.
- It is calculated by adding lead time demand to the desired safety stock level.
- Setting accurate reorder points prevents both stockouts and excess inventory accumulation.
What the Reorder Point Is
The reorder point (ROP) is the specific inventory quantity that triggers a new replenishment order. When stock on hand falls to this level, it signals that enough inventory remains to cover demand during the lead time required for the new order to arrive. Setting the reorder point correctly ensures continuous product availability without ordering too early, which would inflate inventory carrying costs unnecessarily.
How to Calculate the Reorder Point
The standard formula is: Reorder Point = (Average Daily Demand x Lead Time in Days) + Safety Stock. For example, if a retailer sells 50 units per day with a 10-day lead time and maintains 200 units of safety stock, the reorder point is 700 units. When inventory drops to 700, a new order is placed, and the safety stock covers any variability during the replenishment period.
Factors Affecting the Reorder Point
Lead time is the most critical factor. Businesses sourcing from overseas suppliers face longer lead times than those using local sources. Demand variability also matters: a product with volatile sales needs a higher reorder point than one with steady, predictable demand. Companies importing goods through African ports should account for potential customs delays, shipping disruptions, and inland transport times when setting their reorder points.
Automating Reorder Point Management
Modern inventory management systems continuously monitor stock levels and automatically generate purchase orders when the reorder point is reached. This eliminates manual tracking errors and ensures timely replenishment. Sophisticated systems dynamically adjust reorder points based on changing demand patterns and lead times. Even small and medium businesses across Africa are increasingly adopting cloud-based inventory tools that automate these calculations.
