Amazon's own Seller app lets you scan barcodes to check whether you are allowed to sell an item, estimated fees and current offers. It is the first tool every new Amazon reseller should install.
SellerAmp SAS (Selling Assistant) is a browser extension and mobile app that calculates profit, ROI, eligibility, Buy Box share and alerts for any Amazon product, using your own fees and buy cost. It is the most popular deal-analysis tool among arbitrage sellers.
Retail and online arbitrage on Amazon live and die by data: sales rank, price history, Buy Box competition, fees and ungating restrictions. These tools range from free browser extensions to full research suites. Beginners usually start with one scanner app plus Keepa, and add a sourcing suite once they are consistently profitable. The deciding factors usually come down to each tool's standout strength (for Amazon Seller App: free and official; for SellerAmp SAS: fast profit and roi calculations) weighed against its main drawback (limited historical data versus arbitrage-specific).
