See every featureAlertr calculates how quickly every SKU is selling using your real Shopify order data, then estimates when each item will run out. Set your lead time, safety stock runway, and per-SKU multipliers to see exactly what to reorder and how much. Get daily email or Slack alerts when stock drops below your thresholds. Filter by out-of-stock, low stock, or needs-reorder, and export to CSV.
Built for Stocky users, Kestori sends a daily low-stock digest that uses recent sales velocity instead of static thresholds, so reorder timing follows how each SKU is selling. Familiar fields for SKU, inventory on hand, days left, and suggested reorder quantity keep the migration simple. The forecast is directional and should be reviewed before ordering.
