Days of cover, reorder point and order quantity from daily sales, lead time and safety stock
Reorder point = daily sales × (lead time + safety days): order when stock falls to it and the next batch lands just before the shelf empties. The order quantity first lifts stock to lead time + cover days, subtracts what is on hand and inbound, then rounds up to the MOQ. Base daily sales on real outbound from the last 14–30 days, and raise it by hand for campaigns or season changes — this extrapolation ignores trends.
