See every featureSafety Stock prevents overselling by keeping a buffer of inventory in reserve. Instead of waiting until stock hits zero, the app marks a product as sold out once its available quantity reaches the threshold you set, so the remaining units stay protected for in-store sales, samples, or pending orders.
Stock Sentry helps you monitor product inventory and get notified when stock reaches your chosen threshold. Create watches for the products you care about and receive email and Slack alerts when inventory changes. Manage alert settings in-app, including thresholds and notification preferences. View alert history and use analytics to understand which products trigger the most alerts and keep tracking organized.
- Reserve retail stock so products show sold out before inventory reaches zero
- Set thresholds store-wide or for specific store, products, collections, and tags
- Set rule priorities so that your preferred threshold wins when rules overlap
- Instant email alerts when products hit your custom low-stock threshold.
- Smart "Spam Prevention" blocks duplicate alerts to keep your inbox clean.
- Visual Analytics Dashboard: Track inventory health & most-alerted items.
- Slack Integration that allows alerts to show directly on your channel
