Overview
About Alertr: Inventory Management
The simplest Shopify inventory app on the market. 1-click setup. Tracks what's about to run out, tells you when to reorder.
Manual stock checks miss things. By the time you notice, you've already lost sales. Spreadsheets go stale. Shopify's built-in tools don't alert you proactively. The apps that do cost $40-$250/mo.
Syncs your inventory daily, calculates sell rates, and alerts you when stock drops below your thresholds. Configue your own assumptions and export your data to CSV.
