Specific answers for teams replacing InventoryPlanner with ReorderStock Studio.
Reorder Point (ROP) equals (Average Daily Unit Sales × Average Lead Time in Days) + Statistical Safety Stock. When your available inventory (On-Hand + On-Order) drops to the ROP, you must place a new Purchase Order immediately.
Using King's statistical equation: Safety Stock = Z × sqrt((Average Lead Time × Demand Standard Deviation²) + (Average Daily Sales × Lead-Time Standard Deviation)²), where Z is your service-level factor (1.65 for 95%, 2.33 for 99%).
Most sellers apply a 98%–99% service level (Z = 2.05 to 2.33) to their top 20% hero SKUs where stockouts destroy organic ranking, and a 90%–95% service level (Z = 1.28 to 1.65) to slower-moving catalog SKUs.
Yes. Total replenishment lead time must include factory production days + ocean/air transit + customs clearance + Amazon FC check-in and receiving transfer days (typically 10–18 extra days).
Never. All CSV parsing, Z-score safety stock calculations, and PO working capital projections execute 100% locally in your browser RAM.
While Inventory Planner ($119+/mo) and Prediko charge recurring monthly fees tied to your store revenue, ReorderStock Studio is a one-time $19 lifetime buyout for instant, zero-login multi-SKU reorder point and safety stock modeling.
