Rocket Source

Comprehensive Product Intelligence

Rocket Source delivers an exhaustive analysis by providing over 90 distinct data points for every single product scanned. This goes far beyond simple profitability metrics to include vital information on demand, competition, and Amazon-specific restrictions. Users gain insights into product variations, pack quantities, dimensions, weight, and category health, creating a 360-degree view of each product's potential and pitfalls directly within their supplier list.

Real-Time Profitability Calculation

The platform eliminates guesswork by integrating real-time data from Amazon's API and Keepa to calculate true net profit. It automatically factors in the current Buy Box price, precise Amazon FBA fees (including storage and fulfillment), and estimated shipping costs. This allows sellers to see an accurate, real-world profit margin for each item in seconds, ensuring purchasing decisions are based on hard data rather than manual estimation.

Advanced Restriction & Risk Flagging

Rocket Source proactively identifies potential roadblocks and risks that could derail a listing. The system flags products for critical issues such as Amazon brand gating, hazmat restrictions, small and light eligibility, and the presence of product variations. This early warning system prevents sellers from investing in inventory that may be unsellable or require special approval, safeguarding capital and operational time.

Enterprise-Grade Scalability & Global Reach

Designed for businesses of all sizes, the platform can process massive supplier files containing over 500,000 product rows without performance degradation. Furthermore, it supports analysis across 18 different Amazon marketplaces worldwide, from North America and Europe to Asia and Australia.

Wholesale Sourcing Analysis

Wholesalers and distributors can upload their entire supplier catalogs or price lists to instantly evaluate the profitability of thousands of products for Amazon resale. Instead of manually checking each item, they can filter and sort by net margin, sales rank, and competition to quickly identify the most promising wholesale opportunities, negotiate better deals with suppliers, and build a data-backed inventory portfolio.

Retail Arbitrage & Online Arbitrage Scouting

Retail arbitrage professionals use Rocket Source to analyze scanned or exported product lists from retail stores or online marketplaces.

Inventory Risk Mitigation for Large Brands

Major brands and large sellers utilize the platform to vet new products before large-scale purchasing. By analyzing for restriction flags, variation complexity, and historical price volatility, they can avoid costly mistakes like buying inventory that is brand-gated, has too many competing offers, or is in a declining market, thereby protecting their investment and ensuring smoother inventory turnover.

Product Research & Category Expansion

Sellers looking to expand into new product categories can use supplier data to research market viability. By uploading potential product lists, they can assess average profitability, demand (via BSR), and competitive saturation within a new niche.
