My bestseller keeps going out of stock during sales, how do I fix my reorder timing?

If your bestseller stocks out during sales, your reorder point is calibrated to average demand, not peak demand, that's a formula problem, not a panic-ordering problem. Set the reorder point using your peak daily velocity (not average) times lead time, plus a safety buffer, and fire the PO the instant you hit that trigger rather than when the warehouse calls you in a panic. For India specifically, build in extra lead-time buffer around festive quarters, Diwali, EOSS, when your manufacturer's other clients are also maxing out capacity.
