Feature Comparison

Rocket Source

AI-Powered Supplier File Analysis

This core feature eliminates manual data entry and guesswork. You upload any supplier spreadsheet or catalog file, and Rocket Source's AI automatically identifies and maps the relevant columns (like UPC, SKU, or ISBN) to scan products. It then cross-references every item against live Amazon data, returning a comprehensive analysis for each one. This process, which would take a human days, is completed in just minutes, turning a massive file into a digestible list of opportunities.

Comprehensive Profitability & Data Dashboard

For every product scanned, Rocket Source provides a deep dive with over 90 data points. This goes beyond simple price checks to give you a complete picture. You get accurate profitability calculations using real Buy Box prices and official Amazon FBA fees, demand indicators like BSR and category rank, competition levels, and vital warnings for restrictions like Hazmat or brand gating. This dashboard empowers you to evaluate deals based on full transparency, not just rough estimates.

Advanced Filtering & Collaboration Tools

Use Cases

Rocket Source

Wholesale Sourcing from Large Distributors

Wholesale sellers often receive massive product catalogs from major distributors like McKesson or Luxottica. Manually checking even a fraction of these products is impossible. With Rocket Source, you can upload the entire distributor spreadsheet and within minutes have a filtered list ranked by profitability, demand, and eligibility, allowing you to quickly identify the top wholesale deals to pursue from a sea of options.

Online Arbitrage Deal Hunting

Online arbitrage sellers scour retail websites for underpriced products to resell on Amazon. When you find a large sale or clearance list, you can compile the items into a file and upload it to Rocket Source. The tool will instantly check each product's current Amazon price, fees, and restrictions, showing you exactly which discounted items offer a real, profitable margin after all costs, saving you from buying dead inventory.

Validating Private Label Product Ideas

Before investing in a private label product, sellers research competition and demand. You can use Rocket Source to analyze a list of competitor ASINs in your niche. The tool will provide data on their BSR, number of offers, fee structures, and category health. This intelligence helps you validate market demand, understand the competitive landscape, and estimate your potential costs and profits more accurately.

Managing Inventory & Avoiding Restrictions

Avoiding gated brands or restricted products is critical. A seller can use Rocket Source's brand blocking feature to automatically filter out problematic brands from any supplier list. Furthermore, by reviewing the "Flags" and restriction data for every scanned product, you can proactively avoid purchasing items that are Hazmat, require approval, or have other selling limitations, preventing costly listing blocks or stranded inventory.

Frequently Asked Questions

Rocket Source FAQ

What kind of files can I upload to Rocket Source?

Rocket Source is designed to work with common supplier catalog formats. You can typically upload spreadsheet files like .XLSX or .CSV. The AI is built to automatically detect and map columns within these files, such as product identifiers (UPC, EAN, ISBN, ASIN), cost, and title, making the setup process quick and straightforward.

How accurate are the profit calculations?

The profit calculations are highly accurate because they use real-time data. Rocket Source pulls the current Buy Box price directly from Amazon and, most importantly, uses the official Amazon FBA Fee Calculator API to get precise fulfillment fees based on the product's dimensions and weight. This means your estimated profit margin reflects actual Amazon costs, not rough estimates.

Can I use Rocket Source for marketplaces outside the USA?

Yes, absolutely. Rocket Source supports scanning products across 18 different global Amazon marketplaces. This allows sellers who operate in multiple countries, like the UK, Canada, Germany, or Japan, to analyze supplier deals specific to each marketplace's prices, fees, and demand, all from a single platform.

Is there a limit to the number of products I can scan?

Rocket Source is built to handle very large volumes. It can process individual supplier files containing over 500,000 rows (products) directly in your browser.
