Alertr 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.
