Feature Comparison

Alertr: Inventory Management

Daily Inventory Sync & Sell Rate Calculation

Alertr automatically connects to your Shopify store to perform a daily synchronization of all product data and recent order history. This process is foundational, as it continuously updates the inventory count for each SKU and, more importantly, calculates the precise daily and weekly sell rate. By analyzing historical sales velocity, the system moves beyond static stock levels to understand dynamic product movement, forming the basis for all predictive alerts and reorder recommendations. This automated data pull ensures your inventory dashboard is always reflecting near-real-time operational metrics without manual intervention.

Smart Reorder Alerts with Threshold Configuration

The application monitors your inventory levels against configurable, per-SKU thresholds that you define. When stock for an item falls below its designated reorder point, Alertr triggers an immediate notification. These alerts are delivered via your chosen channels, email or Slack, and contain specific, actionable data: the SKU, current stock level, calculated sell rate, and the exact recommended reorder quantity based on your preset lead time and desired safety stock. This feature replaces guesswork with a calculated procurement instruction.

Centralized Inventory Dashboard

All inventory intelligence is presented within a single, unified dashboard view. Merchants can see a comprehensive list of all SKUs, with key metrics displayed for each: current quantity, days of stock remaining (based on the calculated sell rate), and reorder status. The dashboard includes powerful filtering options to quickly surface items by status, such as "Low Stock," "Needs Reorder," or "Out of Stock." This provides an at-a-glance operational overview, enabling rapid prioritization and decision-making without navigating multiple reports or spreadsheets.

Data Export & Integration Capabilities

For reporting, auditing, or generating purchase orders, Alertr provides a one-click CSV export function. This allows you to download your complete, analyzed inventory data—including sell rates and recommended order quantities—for use in external systems or for sharing with suppliers. Furthermore, the native Slack integration pushes reorder alerts directly into designated team channels, embedding critical inventory tasks into existing team communication workflows and ensuring no alert is missed in an inbox.

Waplify

Waplify offers the capability for unlimited broadcasting, allowing businesses to send messages to a vast number of contacts simultaneously. This feature ensures that marketing teams can reach their audience quickly and efficiently, enhancing engagement and response rates across campaigns.

Contact Management

The platform includes a robust contact management system that allows users to easily organize and categorize their audience. Users can segment their contacts based on various criteria, enabling targeted messaging that resonates with specific customer groups for improved marketing effectiveness.

WhatsApp Business API

By providing access to the official WhatsApp Business API, Waplify ensures compliance and reliability. This feature enables businesses to send automated messages, notifications, and marketing content, enhancing communication while maintaining adherence to WhatsApp's policies.

Analytics Dashboard

Use Cases

Alertr: Inventory Management

Replacing Manual Spreadsheet Tracking

Merchants currently relying on error-prone, static spreadsheets for inventory management can use Alertr to fully automate data collection and analysis. The app eliminates the need for manual data entry, formula updates, and the constant risk of working with stale information. It transforms a hours-long weekly reconciliation task into a fully automated process, freeing up significant operational time for strategic business activities while providing far more accurate and timely insights.

Proactive Prevention of Stockouts

For growing brands where a single stockout can mean significant lost revenue and damage to customer trust, Alertr serves as an essential early-warning system. By calculating sell rates and predicting when an item will hit zero stock based on current velocity, the app provides advance notice—often days or weeks ahead—allowing ample time to place a replenishment order with suppliers and maintain continuous sales availability.

Transitioning from Shopify's Stocky App

With Shopify announcing the sunset of its native Stocky app, merchants require a direct alternative that handles the core inventory management workflow. Alertr is designed as a seamless replacement, offering analogous functionality for sell rate tracking, reorder alerts, and dashboard visibility. It provides a straightforward migration path for Stocky users seeking to maintain operational continuity without adopting a more complex or costly enterprise solution.

Streamlining Team Communication for Reordering

In businesses where inventory responsibility is shared across team members or departments, Alertr's Slack integration centralizes communication. Instead of alerts being siloed in an individual's email, reorder notifications are posted to a shared channel (e.g., #operations or #purchasing). This ensures transparency, enables collaborative discussion on order quantities, and creates an auditable trail of inventory decisions within the team's primary communication platform.

Waplify

E-commerce Promotions

E-commerce businesses can leverage Waplify to launch promotional campaigns directly through WhatsApp. By sending targeted messages about discounts, new product launches, and special offers, companies can increase customer engagement and drive sales effectively.

Customer Support

Service-based businesses can utilize Waplify to enhance their customer support operations. By automating responses to frequently asked questions and providing timely updates, businesses can improve customer satisfaction while reducing response times.

Event Notifications

Organizations planning events can use Waplify to send out invitations, reminders, and updates via WhatsApp. This direct communication channel ensures that attendees receive important information promptly, enhancing the overall event experience.

Feedback Collection

Businesses can employ Waplify to gather feedback from customers post-purchase or after service appointments. By sending surveys or feedback forms through WhatsApp, companies can obtain valuable insights that inform product improvements and customer service enhancements.

Frequently Asked Questions

Alertr: Inventory Management FAQ

How does Alertr calculate the "Days of Stock Remaining" and reorder quantity?

Alertr performs a daily analysis of your sales history for each SKU to determine its average daily sell rate. The "Days of Stock Remaining" is a direct calculation: Current Stock Quantity divided by the Daily Sell Rate. The recommended reorder quantity is calculated using your configurable lead time (days from order to receipt) and a buffer for safety stock. The formula is: (Daily Sell Rate * Lead Time) + Safety Stock Buffer. This provides a data-driven order suggestion to cover the replenishment period.

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

The 14-day free trial provides full, unrestricted access to all features of the Alertr Pro plan. This includes unlimited SKU tracking, daily syncs, smart reorder alerts via both email and Slack, access to the complete inventory dashboard, and CSV export capabilities. No credit card is required to start the trial. At the end of the 14-day period, you will be prompted to subscribe to the Pro plan to continue using the service.

Can I configure different alert thresholds for different products or variants?

Yes, Alertr is designed for granular control. You can set unique reorder points and safety stock parameters for each individual product variant (SKU). This is essential for managing items with vastly different sales velocities, costs, or supplier lead times. For example, a fast-moving bestseller can have a high reorder point, while a slow-moving, high-value item can have a lower one, ensuring capital is optimized across your entire inventory.

How does Alertr handle products with multiple variants (e.g., sizes, colors)?

Alertr syncs and tracks inventory at the variant level directly from Shopify. Each variant with a unique SKU is treated as a distinct item in the inventory dashboard. Sell rates are calculated per variant, and reorder alerts are triggered based on the stock level of the specific variant, not the aggregate stock of the parent product. This ensures precise management for every option you sell.
