Feature Comparison

Alertr: Inventory Management

Daily Inventory Sync & Sell Rate Calculation

Alertr automatically connects to your Shopify store every day to pull the latest product data and order history. It uses this information to calculate the sell rate for each individual SKU, providing you with a data-driven understanding of how quickly each item is moving. This automated daily sync eliminates the need for manual data entry and ensures your inventory insights are always based on the most current information, giving you a reliable foundation for all stock decisions.

Smart Reorder Alerts

Move from reactive to proactive inventory management with configurable alerts. Alertr monitors your stock levels and triggers notifications via email or Slack the moment an item's inventory drops below your predefined threshold. Each alert is intelligent, providing not just a warning but a calculated recommendation for how many units to reorder based on the item's historical sell rate and your set lead time, telling you exactly what to order and when.

Centralized Inventory Dashboard

Gain instant visibility over your entire product catalog through a single, unified dashboard. View all your SKUs organized by critical metrics like days of stock remaining, current sell rate, and suggested reorder quantity. You can quickly filter the view to see only items that are low stock, need reorder, or are out of stock, enabling you to prioritize actions and make informed decisions at a glance without jumping between spreadsheets or reports.

Configurable Thresholds & CSV Export

Tailor Alertr to your specific business operations. You have full control to set key parameters like the lookback window for sell rate calculations, supplier lead times, and how frequently you receive alerts. For reporting and purchase order creation, you can export your complete, up-to-date inventory data with one click to a CSV file, seamlessly integrating Alertr's insights into your existing backend processes.

Replacing Manual Spreadsheet Tracking

Merchants who rely on error-prone and time-consuming manual spreadsheets can use Alertr to automate their entire inventory tracking workflow. The app eliminates the need for daily manual updates and checks by providing automated daily syncs and a real-time dashboard, saving significant administrative time and reducing the risk of human error that leads to stockouts and lost sales.

Proactive Stockout Prevention for Growing Brands
