Alertr: Inventory Management vs fnel

Daily Inventory Sync & Sell Rate Calculation

Alertr automatically connects to your Shopify store every single day to pull the latest product data and order history. It uses this information to calculate the precise sell-through rate for each individual SKU. This continuous, automated tracking is fundamental, eliminating guesswork and ensuring your inventory data is never stale or outdated like a manual spreadsheet. You always have an accurate, real-time view of what products are moving and how fast.

Smart Reorder Alerts via Email & Slack

Stop checking stock levels manually. Alertr proactively monitors your inventory against your custom thresholds. The moment stock for any SKU drops below your set reorder point, you receive an immediate notification. These smart alerts are delivered directly to your email or into your team's Slack channel, telling you exactly which product needs attention and the recommended quantity to reorder based on its current sell rate and your defined lead time.

Centralized Inventory Dashboard

Gain instant visibility over your entire product catalog in one unified view. The Alertr dashboard displays all your SKUs with critical metrics at a glance, including current stock levels, days of stock remaining, sell rate, and calculated reorder quantities. You can quickly filter and sort by status such as "Low Stock," "Needs Reorder," or "Out of Stock," allowing you to prioritize actions and make informed decisions in seconds without jumping between spreadsheets or Shopify pages.

Configurable Thresholds & CSV Export

Tailor Alertr to your specific business operations. You have full control to set your own assumptions, including the sales lookback window for calculating sell rates, supplier lead times, and how frequently you receive alerts. For reporting and creating purchase orders, you can export your complete, up-to-date inventory data with one click to a CSV file, making it easy to share with suppliers or integrate into your broader business planning.

One-Line Setup

With a simple snippet, you can integrate fnel into your platform in just minutes. This quick setup allows you to start tracking events immediately, eliminating the need for complex configurations.

Real-Time Funnel Visualization

Fnel provides real-time visualization of your funnel performance, enabling you to see where users drop off at any given moment. This feature ensures you can react quickly to optimize conversion rates.

Smart Drop-Off Alerts

Fnel automatically detects significant drop-offs in your funnel, alerting you when a step suddenly underperforms. This proactive approach helps you address issues before they impact your overall conversion.

A/B Test Validation

Fnel allows you to run A/B tests and compare variants by step-level conversion rates. This feature helps you make data-backed decisions on which strategies work best for your audience, moving beyond vanity metrics.

Replacing Manual Spreadsheet Tracking

If you are wasting hours each week manually updating spreadsheets and cross-referencing Shopify sales data, Alertr automates this entire process. It syncs data daily and performs all calculations for you, freeing up 3+ hours per week for strategic tasks. This is essential for merchants who have outgrown error-prone manual methods and need a reliable, automated system to prevent costly data entry mistakes and stockouts.

Proactive Prevention of Stockouts

For growing brands, a single stockout on a popular item means lost revenue and disappointed customers. Alertr is designed to prevent this by acting as your early warning system. By tracking sell rates and alerting you the moment inventory dips below safe levels, it ensures you have ample time to reorder and replenish stock before you ever run out, protecting your sales and customer loyalty.

Transitioning from Shopify Stocky

With Shopify shutting down its Stocky app in August 2026, merchants need a capable and straightforward alternative. Alertr handles the same core workflow of sell rate tracking, reorder alerts, and inventory dashboards without unnecessary complexity. It provides a seamless migration path for Stocky users who need to maintain proactive inventory management without disruption to their operations.

Streamlining Team Communication with Slack

For teams that collaborate in Slack, receiving inventory alerts in a shared channel is a game-changer. It ensures the right person—whether in operations, purchasing, or management—sees the alert immediately. This eliminates communication silos, speeds up the reorder process, and creates a transparent, accountable workflow for managing inventory across your entire team.

SaaS Signup Flow

In a SaaS environment, fnel tracks the entire signup funnel—from landing pages to onboarding. You can identify where new users drop off, allowing you to optimize each step for better retention.

E-commerce Checkout Process

For e-commerce businesses, fnel visualizes the checkout process, including cart, shipping, and payment stages. By pinpointing where potential customers abandon their carts, you can implement strategies to reduce drop-offs.

Agency Lead Funnel

Agencies can use fnel to track their lead generation funnels, from form submissions to booked calls. This visibility enables you to validate which marketing campaigns are most effective in converting leads.

A/B Testing for Conversion Optimization

Fnel supports A/B testing for various funnel steps, allowing you to refine your approach based on real user data. This ensures your marketing efforts are focused on strategies that yield the highest conversion rates.

Built from a real-world workflow that saves a DTC brand 3 hours weekly, Alertr provides the proactive inventory intelligence every growing store needs but has been missing. Manual stock checks and stale spreadsheets are unreliable and costly, leading directly to lost sales. Other proactive apps come with a steep price tag of $40-$250 per month. Alertr solves this with a powerful yet simple 1-click setup that delivers daily automated syncs, calculates precise sell rates per SKU, and sends you smart reorder alerts before it's too late.

Unlike traditional analytics platforms such as Google Analytics or Mixpanel, which are burdened with excessive features and complicated setups, fnel simplifies the process with its straightforward approach. With just a single line of code, you can start tracking events and visualize your entire funnel in real-time. This tool is indispensable for solo founders, indie hackers, and early-stage startups that need to rapidly analyze user behavior without the hassle of complex configurations. fnel delivers actionable insights into user interactions during signup, onboarding, checkout, or lead generation flows.

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

Shopify's native tools are reactive; they show you current stock levels but do not proactively predict when you will run out or tell you when to reorder. Alertr is a proactive intelligence layer. It analyzes your historical sales data to calculate sell rates, predicts future stockouts based on those rates, and sends you alerts before you run out. This shift from reactive monitoring to proactive management is essential for preventing lost sales.

What happens during the 14-day free trial?

The 14-day free trial gives you full, unrestricted access to all features of the Alertr Pro plan.

This allows you to fully experience how Alertr automates your inventory workflow and prevents stockouts before making any financial commitment. You can cancel anytime during the trial.

Can I set different reorder points for different products?

Absolutely. Alertr is built for flexibility. You can configure unique thresholds and assumptions for individual products or variants based on their specific sales velocity, supplier lead times, and your business strategy. This granular control is essential for effectively managing a diverse catalog where a best-seller and a slow-moving item have completely different inventory requirements.

Is my data secure with Alertr?

Yes. Alertr connects securely to your Shopify store using official, permission-based APIs. It only accesses the data necessary to provide its service, such as product and order information. Your data is not shared with third parties. You maintain full ownership of your data at all times and can export it via CSV whenever needed.
