Seller Scout — Amazon Reseller Check

Seller Scout is a fast, on-page Amazon FBA reseller tool and profit calculator that adds a deal-analysis panel to every Amazon product page — sales rank, Buy Box seller, FBA fees, and profit/ROI — so you can source smarter in seconds, with no spreadsheets, logins, or extra tabs. THE PROBLEM IT SOLVES Sourcing on Amazon means asking the same questions on every listing: Is there demand? Is Amazon itself on the listing? How many sellers am I up against? What's my profit after FBA fees? Am I even allowed to sell this brand? Checking those one tab at a time is slow. Seller Scout answers all of them in a single floating panel, right on the page. WHAT YOU CAN DO • Sales rank (BSR) demand tier — reads the Best Sellers Rank and maps it to a clear tier: High demand, Medium, Low, or Very low. • "Amazon on listing?" flag — reads the Buy Box "Ships from / Sold by" and shows a RED badge when Amazon is the seller, GREEN for a third-party seller. • Seller count — how many other offers are competing on the listing. • FBA profit calculator — type your buy cost; Seller Scout auto-reads the sell price, estimates the FBA fee (size tier + adjustable referral %), and shows Profit, Margin %, and ROI %. Fees are clearly labeled ESTIMATES. • Brand gating notes — keep your own "approved" and "blocked" brand lists; the panel turns green or red the moment a listing's brand matches. • One-click copy — copy the ASIN, title, or price instantly. WHO IT'S FOR Amazon FBA sellers, online arbitrage and retail arbitrage sourcers, wholesale buyers, and resellers across the US, UK, Canada, and Germany who want a quick, private profit check before buying inventory. PRIVACY — BUILT IN, NOT BOLTED ON • ZERO external APIs. ZERO backend. NO login. • All computation happens on your device, in your browser. • The only data stored is your own settings and brand lists (locally, via chrome.storage.local). Nothing is ever transmitted. • No analytics, no ads, no tracking, no remote code. A NOTE ON FEES Profit, margin, ROI, and FBA fees are ESTIMATES from a built-in fee table for quick triage — not official Amazon quotes. Always confirm in Seller Central before purchasing.
