Feature Comparison
Rocket Source
Automated Supplier Catalog Analysis
Rocket Source automates the most time-consuming step in wholesale sourcing. Instead of manually checking hundreds of supplier spreadsheet lines, users simply upload the file. The AI engine processes it, fetching and integrating live Amazon data for each product in minutes. This automation eliminates human error and saves countless hours, turning a weekly chore into an instantaneous task and allowing sellers to evaluate vastly more opportunities.
Comprehensive 90+ Data Point Profile
For every product scanned, Rocket Source delivers a deep, multi-dimensional analysis through over 90 specific data points. This goes far beyond simple profit estimates to include vital metrics like the number of competing offers, brand gating or Hazmat restrictions, product dimensions, variation details, and BSR percentage within its category. This holistic profile provides the context needed to assess risk, competition, and logistical feasibility alongside pure profitability.
Real-Time Profitability & Fee Calculator
The tool pulls live Buybox prices and automatically calculates all associated Amazon fees, including FBA fulfillment costs, based on the product's size and weight tier. This provides a clear, real-time net profit margin for each item, accounting for the actual cost of sale on Amazon. Sellers can see their true potential ROI before ever contacting a supplier, ensuring they pursue only the most financially sound opportunities.
Intelligent Warning Flags & Filters
Rocket Source pre-analyzes data for potential pitfalls, flagging items with warnings for issues like high competition, non-top-level categories, or the presence of product variations. These derived flags, along with powerful filtering on any data column, enable sellers to instantly sift out undesirable products. This helps avoid common mistakes like investing in gated brands, stagnant inventory, or complex multipacks.

Use Cases
Rocket Source
Evaluating New Wholesale Suppliers
A seller receives a massive catalog from a potential new wholesale supplier. Using Rocket Source, they upload the file and within minutes receive a complete analysis highlighting the top 10 most profitable and in-demand products, while automatically filtering out items that are brand gated or have dangerously high competition. This allows for a rapid, informed decision on whether to pursue a partnership.
Streamlining Existing Supplier Orders
Before placing a routine replenishment order, a seller uploads their supplier's latest price list to Rocket Source. The analysis reveals that two best-selling products now have significantly lower margins due to a recent price drop on Amazon and an increase in FBA fees. The seller adjusts their order quantities accordingly, protecting their profitability.
Expanding into New Product Categories
An established seller wants to diversify into a new category but is unfamiliar with the competitive landscape. They use Rocket Source to analyze generic product lists from distributors in that niche. The data on BSR percentages, top-level category status, and average offer counts provides a clear, low-risk entry point by identifying underserved products with stable demand.
Avoiding Costly Inventory Mistakes
A seller considers a bulk purchase of a seemingly profitable product. Rocket Source's scan reveals a "Hazmat" flag and indicates the product has 15 variations, making inventory management complex. The tool also shows a rapidly worsening sales rank. Armed with this insight, the seller avoids a potentially restricted and slow-moving inventory mistake.
