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.

Wheyindex

100-Point Objective Scoring Algorithm

The platform employs a rigorous, transparent 100-point scoring system to evaluate each protein product objectively. This algorithm is based on quantifiable health and quality criteria, including ingredient purity, sugar and artificial additive content, and the presence of third-party dietary certifications like vegan, gluten-free, or grass-fed. This data-driven approach removes subjective bias, providing a reliable, standardized quality score that allows users to instantly gauge a product's formulation integrity against its peers.

Standardized Price per 25g Pure Protein Metric

Wheyindex introduces a critical financial standardization metric: the price per 25 grams of pure protein. This calculation normalizes cost across all products, regardless of container size, serving suggestions, or brand marketing. It allows for a direct, accurate comparison of true value, enabling users to identify the most cost-effective sources of protein without being misled by package size or serving count discrepancies.

Advanced Multi-Parameter Filtering System

The platform features a highly granular filtering system that allows users to refine search results based on precise specifications. Filters include protein type (e.g., isolate, concentrate, hydrolyzed, blend), allergen-free status (e.g., soy-free, nut-free), specific ingredient exclusions (e.g., no artificial ingredients, no added sugar), dietary claims, brand, and flavor. This enables highly targeted searches to match exact dietary needs and personal preferences.

Real-Time Inflation and Price Tracker

Wheyindex includes a dedicated inflation and price tracking functionality, monitoring cost fluctuations over time. This feature provides historical pricing context, helping users understand market trends and identify the optimal time to purchase. It ensures that the value comparisons and cost-per-protein metrics reflect the most current retail data available from major online retailers.

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.

Identifying Cost-Effective Protein Sources for Budget-Conscious Consumers

Individuals seeking to maximize their protein intake while minimizing expenditure can utilize the standardized "price per 25g protein" metric and sorting filters. By sorting products from low to high based on this metric, users can instantly identify the most economically efficient options, regardless of brand popularity or packaging size, ensuring they receive the best value for their specific budget constraints.

Sourcing Products for Specific Dietary Restrictions and Allergies

Users with dietary restrictions, such as those requiring gluten-free, dairy-free, soy-free, or vegan products, can leverage the advanced filtering system. By selecting multiple "Allergen Free" and "Dietary Claims" filters simultaneously, they can quickly generate a curated list of products that comply with their strict dietary protocols, saving significant time and reducing the risk of purchasing unsuitable supplements.

Selecting Premium, Clean-Label Formulas for Health-Focused Individuals

Health-conscious consumers prioritizing ingredient purity can use the objective score and specific ingredient filters. They can set filters for "No Artificial Ingredients," "No Added Sugar," and "Third Party Tested," then sort results by the highest objective score. This methodology efficiently surfaces products with superior, transparent formulations that align with a clean-label, health-first philosophy.

Comparing Product Formulations for Performance Athletes

Performance athletes requiring specific protein types, such as fast-absorbing hydrolyzed whey or sustained-release blends, can conduct detailed comparative analysis. They can filter by "Protein Type," compare the objective scores and ingredient panels of shortlisted products, and assess the cost efficiency of each using the standardized price metric to make an optimal choice for their training and recovery needs.

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.

Wheyindex FAQ

How is the 100-point objective score calculated?

The score is derived from a transparent, multi-criteria algorithm that quantitatively assesses product quality. Key factors include the purity and quality of the protein source, the amount of sugar and artificial additives, the presence of fillers or unnecessary ingredients, and certifications from third-party organizations (e.g., Informed-Sport, vegan, gluten-free). Each criterion is weighted, and the cumulative result generates a score from 0-100, providing a standardized measure of a product's formulation integrity.

What does "price per 25g of pure protein" mean and why is it important?

This metric calculates the actual cost to obtain 25 grams of protein from a product, after accounting for the total protein content per container and the total price. It standardizes cost across all different container sizes and serving suggestions. This is critically important because it allows for a true, apples-to-apples value comparison, preventing misleading perceptions caused by larger tubs or varying serving sizes that may contain less protein per serving.

How often is the product data and pricing updated on Wheyindex?

The platform's data, including pricing, availability, and product specifications, is updated regularly to ensure accuracy. The context indicates a "Last updated" timestamp, showing a commitment to current information. Real-time price tracking and the inflation tracker feature further imply that pricing data is actively monitored and refreshed to reflect the most current market conditions from linked retailers.

Can I filter for products that meet multiple dietary needs simultaneously?

Yes, the advanced filtering system is designed for complex, multi-parameter searches. You can apply filters across different categories concurrently-for example, selecting "Vegan" under Dietary Claims, "Soy Free" under Allergen Free, and "No Artificial Ingredients" under Ingredient filters. The platform will then display only the products that satisfy all selected criteria, making it highly effective for users with compound dietary requirements.
