What is a reorder point and why it matters
A reorder point is the stock level that tells you, without guesswork, exactly when to place your next purchase order. Get it wrong on the low side and you hit a stockout — disappointed customers, lost sales, and rushed emergency orders at a premium. Get it wrong on the high side and cash sits tied up in overstocked shelves instead of growing your business.
The formula balances two things: how fast a product sells, and how long it takes your supplier to deliver more of it. Add a safety stock buffer on top, and you're covered even when a delivery runs late or a sales week runs hotter than usual.
This matters even more once you're tracking dozens of SKUs across multiple warehouses or store locations — recalculating every reorder point by hand in a spreadsheet doesn't scale. That's exactly the kind of tracking Stocky automates across your whole catalog.
Common questions
A reorder point is the stock level at which you should place a new order to avoid running out before the next delivery arrives. In simple mode it's calculated as (average daily sales × lead time) + (average daily sales × safety buffer days).
