How to find your reorder point
Your reorder point is the stock level where you should place a new order so it arrives before you sell out. Three numbers decide it:
- Average daily sales — how many units of this item you sell per day.
- Lead time — how many days from placing an order to having it on your shelf.
- Safety stock — a buffer for days you sell more than usual or the supplier is slow. An easy way to set it is a number of extra days of sales.
Put together: reorder point = (daily sales × lead time) + safety stock. When you drop to that number, reorder.
Questions
How big should my safety buffer be?
For steady sellers, 3–7 days is common. For items that spike (seasonal, trend-driven) or suppliers that are unreliable, go higher. The buffer trades a little extra cash tied up in stock for a lower chance of selling out.
How much should I order each time?
Enough to bring you back up to cover your lead time, your buffer and however long you want between orders (the days-to-cover above). Ordering more at once cuts shipping and admin but ties up more cash.
