Feature Comparison
Alertr: Inventory Management
Daily Inventory Intelligence Sync
Every morning, Alertr wakes up and gets to work, automatically pulling your latest product data and order history from Shopify. It doesn't just count stock; it analyzes trends, calculating the real-time sell rate for each and every SKU in your catalog. This daily ritual transforms raw data into actionable insight, ensuring you're never making decisions based on yesterday's news. You're always looking at a live, evolving picture of what's moving and what's not.
Smart Reorder Alerts & Predictions
This is the heart of the Alertr story. Instead of you hunting for problems, Alertr brings the solutions to you. It monitors stock levels against your custom thresholds and, using calculated sell rates and your defined lead times, predicts exactly when a stockout will occur. You'll receive a clear, actionable alert via email or Slack that doesn't just say "stock is low," but tells you "Order 50 units of the Classic Silver Necklace by Friday to avoid a stockout." It's like having a seasoned inventory manager on duty 24/7.
Centralized Inventory Dashboard
Banish tab-hopping and spreadsheet chaos. Alertr provides a single, crystal-clear dashboard where every SKU tells its story at a glance. See days of stock remaining, current sell rates, and suggested reorder quantities all in one view. Filter instantly to see only what matters right now: items that are low stock, need a reorder, or are out of stock. This command center puts you back in the narrative of your business, with all the chapters neatly organized.
Configurable Workflow & Export Tools
Your business is unique, and your inventory workflow should be too. Alertr empowers you to tailor the story. Set your own lookback period for sell rate calculations, define supplier lead times, and choose how often you receive alerts. When it's time to place purchase orders or run reports, export your entire inventory snapshot to CSV with one click. Combined with seamless Slack integration for team alerts, Alertr fits into your existing processes, not the other way around.

It replaces guesswork with graceful, automated intelligence, ensuring your story is always about growth, not gaps.

Frequently Asked Questions
Alertr: Inventory Management FAQ
How does Alertr differ from Shopify's built-in inventory tools?
Shopify's native tools are excellent for basic stock level tracking and updates, but they are largely passive. They show you what you have now but don't proactively warn you about what will happen tomorrow. Alertr adds a layer of predictive intelligence. It analyzes your historical sales to calculate sell rates, forecasts future stockouts based on that trend, and actively alerts you with specific reorder recommendations before you run out, filling a critical gap in proactive inventory management.
What happens during the 14-day free trial for the Pro plan?
Your free trial is a full, unrestricted experience of the Pro plan. You'll get immediate access to all unlimited SKU tracking, smart reorder alerts via email and Slack, CSV exports, and the full dashboard. There's no credit card required to join the waitlist and, when launched, to start the trial. This gives you ample time to connect your store, see Alertr in action with your own products, and witness the value of automated inventory intelligence firsthand.
Can I configure Alertr to match my specific supplier lead times?
Absolutely. A key part of setting up your Alertr story is defining your unique business parameters. You can input the specific lead time (in days) for your suppliers or different product categories. Alertr uses this crucial information, combined with the calculated sell rate, to determine the precise moment to alert you, ensuring the "when to reorder" advice is perfectly timed for your real-world supply chain.
Is my data secure, and how does the Slack integration work?
Your data security is paramount. Alertr connects to your Shopify store using a secure, official integration, following all standard data protocols. For the Slack integration, you'll use a simple, permission-based process to connect Alertr to your chosen Slack channel. Once connected, reorder alerts will be posted directly into that channel, keeping your entire team in the loop without needing to check separate emails or dashboards.
