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.
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.
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 Helium 10: very broad feature set) weighed against its main drawback (limited historical data versus entry price now $99-$129/mo).
