Stock Alert App

Set a threshold and an email. Stock Alert App writes you the moment a variant crosses it — once per crossing, not on every stock change.

Stock Alert App emails merchants when Shopify inventory crosses a threshold. One alert per crossing. Optional Shopify Flow trigger. Merchants set a quantity threshold and a destination email. When available units on a variant drop to that number or below, Stock Alert App sends one email and logs the crossing. Restocking and crossing again sends another email — routine stock moves do not. Shopify Flow is optional. A Flow trigger is available if the merchant wants Slack, tags, or a custom workflow after the same crossing. The app is free ($0). Dashboard, threshold alerts, email, activity log, and an optional Flow trigger are included. There is no paid plan. Permissions: read products, inventory, and locations — only what is needed to name the variant, SKU, and place in the email.

• One email when a variant crosses your quantity threshold — not on every stock change.
• Dashboard of recent crossings so you can see what went low without opening inventory.
• Optional Shopify Flow trigger after the same crossing for Slack, tags, or a custom workflow.
