When should you reorder?

Reorder too late and you stock out on your best sellers; too early and cash sits on the shelf. Find the point that avoids both — from your sales rate, supplier lead time, and a safety buffer.

Formula: reorder point = (average daily sales × lead time) + safety stock. It assumes steady demand — real demand shifts with seasonality and trends. That is what Kesper watches for you: SHERLOCK tracks each SKU's velocity nightly and PROPHET projects demand from your real history, so reorder alerts move with the actual numbers instead of a fixed guess.

Never guess the reorder point again.

Kesper watches velocity and demand across every SKU and flags what to reorder — before the shelf goes empty. $49/month flat, 7-day free trial, no card.
