Most D2C teams do not have an inventory math problem. They have an execution rhythm problem. Resetting your stock system in 30 days starts with one SKU list, one owner, and one weekly review cadence.
In week one, clean your SKU master and remove duplicate naming. In week two, set baseline demand, lead time, and service level by product family. In week three, compute fresh reorder points and safety stock. In week four, automate alerts for exceptions only.
The result is fewer panic purchase orders, lower dead stock, and a clearer working capital plan. Keep this loop monthly and your forecasting quality compounds each cycle.
