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.
documentorium
Trade-Specific Template Library
documentorium offers a curated catalog of more than 200 document templates organized into 26 trade-specific categories. This means an electrician's service report template will have fields for circuit breakers and amperage, while a plumber's estimate will include line items for pipe materials and fixture installations. This specialization removes guesswork and ensures every document is relevant and professionally structured for the specific job at hand, far surpassing generic office software.
Guided Form-Filling Interface
The platform uses an intuitive, step-by-step form interface to guide users through document creation. Users are prompted to enter information into logical, clearly labeled fields rather than manipulating a complex layout. This structured approach minimizes errors, saves time, and ensures all necessary details are captured efficiently, making the process straightforward even for those who are not tech-savvy.
Instant PDF Generation and Output
Upon completing a guided form, documentorium instantly compiles the information into a clean, professionally formatted PDF document. This PDF is immediately ready for printing, emailing to clients, or digital archiving. The system handles all design, layout, and formatting automatically, delivering a polished result without any manual design work required from the user.
Complete Document History and Prefill
Every document created is saved in the user's personal account history. This archive allows for easy retrieval, re-downloading, and reference. Furthermore, the system can intelligently prefill information from past documents into new ones, such as pulling client details or standard service descriptions, dramatically speeding up the creation of recurring documents like invoices or maintenance reports.
Use Cases
Alertr: Inventory Management
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
Growing e-commerce brands that cannot afford the reputational damage and revenue loss from frequent stockouts utilize Alertr's predictive alerts. By setting thresholds based on sell rates and lead times, merchants receive advance notice to reorder best-selling items, ensuring popular products are always in stock to meet customer demand and sustain sales momentum.
Transitioning from Shopify's Stocky App
With Shopify announcing the shutdown of its native Stocky app, merchants who depend on it for core inventory management need a direct alternative. Alertr is designed to handle the same essential workflow—tracking sell rates, generating reorder alerts, and providing inventory dashboards—offering a straightforward migration path without the complexity of larger enterprise systems.
Streamlining Team Communication with Slack
Teams that use Slack for internal coordination can integrate Alertr to send reorder alerts directly into a designated channel. This ensures that the relevant personnel in operations, purchasing, or management are immediately notified of low stock levels in their primary communication tool, facilitating faster decision-making and collaborative reorder actions.

Issuing a Formal Quote or Estimate

Using a trade-specific template, they can itemize materials, labor costs, timelines, and terms. The instant generation of a professional PDF quote allows them to present it to the homeowner immediately, improving the likelihood of securing the job without delay.
Managing Work Orders and Service Reports
An HVAC technician completing a maintenance call can fill out a guided service report template directly on a tablet. They can document diagnostics, parts used, services performed, and recommendations. The resulting PDF serves as an official record for the client, a billing document for the office, and a historical log for future service visits, all created in minutes.
Handling Change Orders and Contract Modifications
For a roofing project where additional work is requested, the project manager can swiftly generate a formal change order.

Frequently Asked Questions
Alertr: Inventory Management FAQ
How does Alertr calculate when to alert me for a reorder?
Alertr calculates reorder points by analyzing your daily sell rate for each SKU and your configured supplier lead time. It uses the formula: Reorder Point = (Daily Sell Rate * Lead Time in Days) + Safety Buffer. When your current stock level falls at or below this calculated point, the system triggers an alert. You can customize the lookback period for the sell rate calculation and the lead time to match your specific supply chain.
What happens during the 14-day free trial?
The 14-day free trial provides full access to all features of the Alertr Pro plan.

If you choose to subscribe after the trial, you will be billed at the locked-in beta price of $19 per month.
Can I use Alertr if I have more than 50 SKUs on the Free plan?
No, the Free plan is specifically designed for small stores or those just getting started and is limited to monitoring up to 50 unique SKUs.
