Helium 10 is a large suite of Amazon seller tools: product research (Black Box), keyword research (Cerebro, Magnet), listing optimisation, profit analytics and alerts. The entry-level Starter plan was discontinued, so it now makes most sense for sellers with real volume.
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 Helium 10: very broad feature set; for SellerAmp SAS: fast profit and roi calculations) weighed against its main drawback (entry price now $99-$129/mo versus arbitrage-specific).
