Feature Comparison

Alertr: Inventory Management

Daily Inventory Sync & Sell Rate Calculation

Alertr automatically connects to your Shopify store every single day, pulling the latest product data and order history. It doesn't just show you current stock levels; it intelligently calculates the sell rate for each individual SKU. This foundational feature transforms raw data into actionable insight, giving you a crystal-clear, daily updated view of exactly what's moving fast, what's slow, and how many days of inventory you realistically have left before a potential stockout.

Smart Reorder Alerts with Custom Thresholds

Move beyond basic low-stock notifications. Alertr allows you to configure your own assumptions, including lead time and desired safety stock. The system then uses your calculated sell rates to predict exactly when you'll run out and sends proactive alerts via your chosen channel (Email or Slack). It doesn't just say "stock is low"—it tells you precisely how many units to reorder and when to place the order to avoid disruption, acting as your automated inventory planner.

Centralized Inventory Dashboard

Gain instant visibility over your entire inventory landscape from one intuitive dashboard. View all SKUs organized by critical status: low stock, needs reorder, or out of stock. See key metrics at a glance, including days of stock remaining and calculated reorder quantities. This feature consolidates disparate data points into a single source of truth, enabling rapid, informed decision-making without ever needing to open a spreadsheet or manually check multiple reports.

Data Export & Slack Integration

For deeper analysis or generating purchase orders, Alertr provides a straightforward CSV export of your complete inventory data. Furthermore, its native Slack integration transforms inventory management into a collaborative team effort. Critical reorder alerts are delivered directly into your designated Slack channel, ensuring your entire team is instantly aware and can act swiftly, keeping everyone aligned and accountable without email clutter.

Use Cases

Alertr: Inventory Management

Replacing Manual Spreadsheets & Stock Checks

For merchants drowning in manual spreadsheets and weekly stock check rituals, Alertr is a liberation tool. It automates the entire data collection and calculation process, replacing error-prone, stale spreadsheets with a live, automated system. This reclaims hours every week, eliminates human error, and provides accuracy that manual methods can never match, allowing you to focus on growth instead of data entry.

Proactive Prevention of Stockouts & Lost Sales

This is the core transformative use case. Alertr is for any merchant who has ever been surprised by an out-of-stock bestseller. By tracking sell rates and providing early warnings, it shifts your strategy from reactive to proactive. You receive alerts with ample lead time to reorder, ensuring popular items never go out of stock on your live store, directly protecting your revenue and customer satisfaction from preventable losses.

Finding a Stocky Alternative

With Shopify shutting down its native Stocky app in August 2026, many merchants need a powerful, straightforward replacement. Alertr is perfectly positioned as that alternative, handling the same essential workflow—sell rate tracking, reorder alerts, and inventory dashboards—but with a simplified, user-friendly interface and transparent pricing, making the transition seamless and effective.

Streamlining Team Communication for Reorders

For brands where inventory management involves multiple team members (e.g., owner, operations manager, assistant), Alertr's Slack integration revolutionizes workflow. Instead of alerts getting lost in an inbox, they are broadcast to a shared channel. This ensures immediate visibility, enables quick discussion, and creates a clear, auditable trail for when reorder decisions are made, fostering seamless team collaboration.

Size The Market

Dynamic Pricing Strategy Optimization

E-commerce retailers can revolutionize their pricing approach by using real-time competitor data to inform dynamic pricing rules. By understanding the exact market price for any product at any moment, businesses can automatically adjust their own prices to stay competitive, maximize margins, or win the Buy Box on marketplaces. This transforms pricing from a static guess into a dynamic, profit-optimizing engine that reacts intelligently to market fluctuations.

Brand Protection & MAP Compliance Enforcement

Manufacturers and brand owners can proactively safeguard their brand equity and retailer relationships. The platform automatically detects Minimum Advertised Price (MAP) violations across a vast network of online retailers, providing undeniable evidence and enabling swift, structured enforcement. This use case is transformative for maintaining price integrity, ensuring a level playing field for all partners, and protecting the perceived value of the brand in the consumer's eye.

Market Entry & Expansion Analysis

Businesses looking to launch a new product line or enter a new geographic market can de-risk their strategy with comprehensive market intelligence. By analyzing competitor positioning, pricing tiers, and promotional cadences in a target category or region, companies can size the opportunity accurately, identify gaps in the market, and set an optimal launch price. This data-driven approach replaces assumptions with evidence, unlocking potential for successful market penetration.

Retailer & Agency Performance Reporting

E-commerce agencies and retail analysts can elevate their client service and internal reporting with automated, comprehensive competitive insights. Instead of manually compiling data, they can generate detailed reports on market trends, competitor activity, and pricing benchmarks with a few clicks. This game-changing efficiency allows them to provide higher-value strategic counsel, demonstrate clear ROI, and make faster, more informed recommendations to drive client growth.

Frequently Asked Questions

Alertr: Inventory Management FAQ

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

Shopify's native tools are passive; they show you current stock levels but do not predict the future or proactively warn you. Alertr is an active intelligence layer. It analyzes your historical sales data daily to calculate sell rates, predicts exactly when you will run out based on your custom lead times, and sends alerts before it happens. It transforms raw data into actionable, forward-looking insights that Shopify's basics cannot provide.

What happens during the 14-day free trial for the Pro plan?

The 14-day free trial gives you full, unrestricted access to all Pro plan features. This includes unlimited SKU tracking, setting up email and Slack alerts, using the complete dashboard, and exporting CSV reports. You can fully integrate and test Alertr in your live store environment without any cost. There is no credit card required to join the waitlist, and you will have the option to start your trial when the app launches.

Can I configure Alertr for products with long or variable supplier lead times?

Absolutely. A key strength of Alertr is its configurability. You can set custom lead time assumptions for your entire store or for individual products. This means if a particular SKU has a 60-day lead time from your supplier, Alertr will factor that into its calculations and alert you much earlier than it would for an item with a 7-day lead time, ensuring you always have enough runway to restock.

Is my data secure, and how does the daily sync work?

Your data security is paramount. Alertr connects to your Shopify store using secure, official API protocols, the same method used by all certified Shopify apps. It only pulls the product and order data necessary for its calculations. The daily sync is an automated, behind-the-scenes process that updates your sell rates and stock predictions without any manual intervention required from you, ensuring your insights are always fresh.
