Finding winning products on Amazon usually means spending hours switching between tabs, managing complex Excel spreadsheets, and calculating profit margins manually.
To solve this for Amazon sellers, I built SellerScope Global — a free Chrome extension designed to streamline product research into a fast 3-step workflow.
🛠️ The Core Problem
When evaluating an Amazon product, sellers need to quickly check:
Sales Estimates & BSR: Is the product actually selling?
Profit Margins & Fees: After FBA fees and GST/taxes, is there enough margin left?
Competition: Is the niche too crowded for a new seller?
Most existing tools require expensive monthly subscriptions ($50–$99/month), which can be a heavy barrier for beginner and growing sellers.
🚀 How SellerScope Global Automates Research
Instead of leaving the Amazon product page, the extension overlays essential data directly on top of the listing:
📊 Opportunity Score (0–100): Instantly gauge market demand vs. competition.
📈 Monthly Sales Volume & BSR Tracking: Get quick estimates of how many units sell per month.
💰 FBA Profit & Margin Calculator: Factoring in fulfillment fees, product costs, and GST automatically.
💡 Tech Stack & Architecture
For fellow developers interested in how browser extensions process real-time page data:
Manifest V3: Built using the latest Chrome Extension API specs for better security and fast content scripts.
Content Scripts: Used to extract key page parameters (ASIN, BSR, pricing) without slowing down page render times.
Background Service Workers: Handles API requests and background calculations asynchronously.
