Reorder Point

The stock level that triggers a new purchase order to avoid running out.

Definition

A reorder point (ROP) is the minimum quantity of an item that should remain in stock before a replenishment order is placed. When inventory drops to or below this level, it signals that it is time to reorder — ensuring stock arrives before you run out.

Formula

Reorder Point = (Average Daily Usage × Supplier Lead Time in Days) + Safety Stock

Why It Matters

Without a reorder point, restocking happens reactively — only after an item runs out. This causes stockouts, emergency orders, and disruption. Setting a reorder point for each supply item turns reactive ordering into a proactive system. It is one of the highest-leverage changes an office manager can make.

Example

Your office uses 2 reams of printer paper per day. Your supplier takes 3 days to deliver. You keep 4 reams as safety stock. Reorder Point = (2 × 3) + 4 = 10 reams. When stock drops to 10 reams, place an order.
