Feature Comparison

Alertr: Inventory Management

Daily Inventory Sync & Sell Rate Calculation

Alertr automatically connects to your Shopify store to pull product and order data every single day. It uses this fresh information to perform a critical calculation: determining the sell rate for each of your SKUs. This means you always have an accurate, up-to-date understanding of how quickly each item is moving, which forms the foundational data for all smart reordering decisions, eliminating reliance on outdated spreadsheets or manual estimates.

Smart Reorder Alerts via Email & Slack

This is the core automation that prevents stockouts. Based on your calculated sell rates and configurable settings like lead time and reorder point, Alertr proactively monitors your inventory levels. When stock for a product dips below your predefined threshold, it instantly sends you a clear alert. These notifications can be delivered directly to your email or into a designated Slack channel, telling you precisely which item needs attention and how many units you should order to replenish safely.

Centralized Inventory Dashboard

Gain immediate visibility over your entire product catalog in one unified view. The Alertr dashboard displays all your SKUs alongside key metrics like current stock level, days of stock remaining, sell rate, and suggested reorder quantity. You can quickly filter this view to see only items that are low in stock, need reordering, or are out of stock, allowing for efficient and focused inventory management without jumping between different reports or screens.

Configurable Thresholds & CSV Export

Alertr adapts to your specific business needs. You have full control to set important parameters like the sales lookback period for calculating sell rates, supplier lead times, and how frequently you receive alerts. For reporting or creating purchase orders, you can export your complete inventory data—including all calculated metrics—to a CSV file with one click, ensuring you have the records you need for external processes or analysis.

Use Cases

Alertr: Inventory Management

Replacing Manual Spreadsheet Tracking

Merchants who currently track inventory using manual spreadsheets face constant challenges with stale data and human error. Alertr automates this entire process by syncing daily sales data directly from Shopify, calculating sell rates automatically, and providing a live dashboard. This eliminates hours of manual data entry and reconciliation, ensuring decisions are based on accurate, real-time information rather than outdated guesses.

Proactively Preventing Lost Sales from Stockouts

A common pain point is discovering a product is out of stock only after a customer attempts to buy it, resulting in a lost sale. Alertr addresses this by continuously monitoring inventory levels against sales velocity. It provides early warning alerts while you still have time to reorder, ensuring popular items are always available for purchase and protecting your revenue stream from avoidable interruptions.

Finding a Simple, Affordable Alternative to Stocky

With Shopify's native Stocky app shutting down, many merchants need a new solution. Alertr serves as a direct and simpler alternative, handling the essential workflows of sell rate tracking, reorder alerts, and dashboard visibility. It offers this core functionality at a transparent and more affordable price point, making it an ideal replacement for those seeking effective inventory management without excessive complexity or cost.

Streamlining Team Communication for Reordering

For businesses where multiple team members are involved in inventory management, communication gaps can lead to delays. Alertr’s Slack integration sends reorder alerts directly into a team channel. This creates a shared, immediate, and actionable notification system, ensuring the right person sees the alert and can act on it promptly, streamlining the entire procurement workflow.

Frequently Asked Questions

Alertr: Inventory Management FAQ

How does Alertr calculate when to alert me to reorder?

Alertr uses a straightforward, foundational formula. First, it calculates the daily sell rate for each SKU by analyzing your recent sales history (over a lookback period you can configure). It then multiplies this sell rate by your configured supplier lead time (in days) to determine how much stock you'll likely sell while waiting for new inventory. When your current stock level falls below this calculated quantity plus any safety buffer you set, Alertr triggers a reorder alert. This ensures you're notified with enough lead time to prevent a stockout.

What happens during the 14-day free trial?

The 14-day free trial gives you full access to all features of the Alertr Pro plan. You can connect your Shopify store, configure your reorder thresholds, set up email and Slack alerts, and use the dashboard and export tools. There is no credit card required to start the trial. This period allows you to fully test how Alertr integrates into your workflow and proves its value in preventing stockouts before any commitment is required.

Can I use Alertr if I have a very large number of SKUs?

Yes. The Pro plan supports an unlimited number of SKUs. Whether you have dozens or thousands of products, Alertr will sync data for all of them daily, calculate individual sell rates, and monitor each one against your reorder thresholds. The dashboard is designed to handle large catalogs efficiently, with filtering and search tools to help you manage your inventory at scale without performance issues.

How does Alertr differ from Shopify's built-in inventory tools?

Shopify's basic inventory tools are primarily reactive; they show you current stock levels but do not proactively analyze sales trends or predict future stockouts. Alertr adds a vital layer of intelligence. It analyzes your historical sales data to calculate sell rates, uses that data to forecast when you'll run out, and proactively sends alerts before it happens. This shift from reactive monitoring to proactive forecasting is the key difference that saves time and prevents lost sales.

Do I lose my documents if I don't subscribe?

No, users will not lose their documents if they decide not to subscribe. All documents remain in their history and can be viewed and downloaded at any time. However, a subscription is necessary to create and edit new documents.

How does documentorium ensure documents are trade-specific?

documentorium ensures that each template is designed with specific fields for various trades. This means that users are not left with generic blanks but instead have forms that reflect the unique requirements of their profession, making document creation relevant and efficient.
