Alertr tracks your Shopify sell rates daily and predicts stockouts before they happen. Instead of basic threshold alerts, it calculates days of stock remaining per SKU based on actual velocity — so you know what's moving and how fast. The app sends smart reorder alerts by email or Slack, including exactly how many units to order based on your supplier lead time and current sell rate. A single inventory dashboard shows all your SKUs filtered by status: low, critical, or out of stock. It works in about 10 minutes — install from the Shopify App Store and Alertr immediately starts pulling product data and order history with no CSV uploads or manual setup. Configurable lookback windows and alert preferences let you tailor it to your store. Free for up to 50 SKUs; the Pro plan at $29/mo adds unlimited SKUs, Slack integration, and CSV export.
