Calculate reorder point
A reorder point helps you know when inventory should be replenished before stock runs out. Enter average daily demand, supplier lead time and safety stock to calculate the reorder point. It is useful for ecommerce inventory, small warehouses, purchasing plans and supplier lead-time reviews.
Lead-time demand plus safety stock
The result estimates how many units should trigger a new purchase order or replenishment request.
