How This Works

Daily Velocity is calculated differently by planning mode: Conservative uses 30-day average, Normal uses a weighted blend (50% 7-day, 30% 14-day, 20% 30-day), and Aggressive uses 7-day average.

Restock Point = (Daily Velocity × Lead Time) + Safety Stock. When your total available inventory drops to or below this level, it's time to reorder.

Qty to Order is rounded up to the nearest case pack and is always at least your MOQ.
