Alertr: Inventory Management vs Rocket Source

Daily Inventory Sync & Sell Rate Calculation

Alertr automatically connects to your Shopify store to pull product data and recent orders every single day. It doesn't just show you static stock levels; it actively calculates the sell rate for each SKU based on your actual sales history. This means you always have a real-time, data-driven understanding of what's moving fast and what's sitting still, providing the foundational intelligence for all proactive reordering decisions without any manual data entry.

Smart Reorder Alerts via Email & Slack

Move beyond checking dashboards and get notified directly. Alertr monitors your stock levels against customizable thresholds and your calculated sell rate. The moment an item is predicted to run out, you receive a clear, actionable alert. These notifications tell you exactly which product is low, how many units you should reorder based on lead time, and can be delivered straight to your email or into your team's Slack channel for instant visibility.

Centralized Inventory Dashboard

Gain instant clarity on your entire inventory health from one unified view. The Alertr dashboard displays all your SKUs with critical metrics like current stock, days of stock remaining, sell rate, and suggested reorder quantity. You can quickly filter to see only items that are "Low Stock," "Needs Reorder," or "Out of Stock," allowing you to prioritize actions and make confident purchasing decisions in seconds.

Configurable Thresholds & CSV Export

Tailor Alertr to your unique business workflow. Set your preferred lookback window for sell rate calculations, define supplier lead times, and customize how often you receive alerts. When it's time to place purchase orders or run reports, export your complete, up-to-date inventory data with one click to CSV for seamless integration with your existing processes, eliminating spreadsheets that go stale.

Automated Data Mapping

Rocket Source intelligently maps the columns of your uploaded supplier spreadsheets, saving you precious time. This feature allows you to start analyzing your data immediately without manual configuration.

Comprehensive Product Insights

With access to over 90 data points per product, Rocket Source goes beyond profitability. It provides crucial information about competition, demand, and restrictions, enabling you to make informed sourcing decisions that can lead to higher sales and profitability.

Full API Access

Available with the Scale plan, Rocket Source includes full API access. This allows you to build custom automations, connect to your inventory systems, and integrate seamlessly with your existing sourcing workflows, all at no additional cost.

Team Collaboration and Workspace Sharing

Rocket Source allows you to block problematic brands and ASINs permanently while also enabling you to share workspaces with your team. This fosters collaboration and ensures everyone is on the same page when analyzing products and making sourcing decisions.

Replacing Manual Spreadsheet Tracking

Merchants spending hours each week updating complex spreadsheets are prone to errors and stale data. Alertr automates this entire process, providing a single source of truth that updates daily. This eliminates manual stock checks, reduces human error, and frees up 3+ hours per week for strategic tasks, all while providing more accurate and actionable data than any manual sheet.

Preventing Costly Stockouts

For growing brands, a single stockout can mean lost sales and damaged customer trust. Alertr proactively monitors inventory and predicts shortages before they happen. By sending alerts based on real sell rates and lead times, it ensures you have enough time to reorder popular items, keeping your bestsellers in stock and revenue flowing consistently.

Finding a Stocky Alternative

With Shopify shutting down Stocky in 2026, merchants need a reliable replacement. Alertr is built to handle the same core workflow—tracking sell rates, sending reorder alerts, and providing inventory dashboards—but with a simpler, more user-friendly interface and transparent pricing, making it the perfect successor for those seeking continuity without complexity.

Streamlining Team Communication for Reorders

In businesses where multiple team members handle inventory or purchasing, communication gaps can delay orders. With Alertr's Slack integration, reorder alerts are posted directly into a designated channel. This ensures everyone is on the same page instantly, speeding up approval and purchase order processes, and creating a collaborative, efficient workflow.

Efficient SKU Analysis

With Rocket Source, Amazon sellers can quickly analyze thousands of SKUs from supplier catalogs in minutes. This speeds up the process of identifying profitable products and helps sellers avoid costly inventory mistakes.

Competitive Market Research

Sellers can use Rocket Source to conduct thorough competitive market research. By understanding the landscape of FBA fees, sales ranks, and offer counts, sellers can position themselves effectively in the marketplace.

Inventory Optimization

Retailers can leverage Rocket Source to optimize their inventory. By filtering results based on specific buy criteria and understanding actual profitability, sellers can ensure they invest in products that are likely to sell quickly and efficiently.

Risk Management

Rocket Source significantly reduces the risk of sourcing products with restrictions or hazards. By highlighting hazmat flags and eligibility issues, it protects sellers from potential compliance issues and financial losses.
