Static reorder points fail when demand shifts between channels or seasons. Velocity-based rules keep cash out of dead stock while protecting winners.
Measure in units per week
Use trailing four-week sell-through per SKU, split by channel if mix matters. Lead time plus safety stock should reflect supplier reality, not a blanket thirty days.
Review monthly
Hero SKUs deserve weekly checks during promos. Long-tail items can stay on monthly review. Change points when velocity doubles or stalls for two consecutive periods.
