What it is
Seller Assistant bundles a side-panel product analyser (Keepa chart, FBA/FBM calculator, ROI, estimated sales), the IP-Alert database, restrictions checker and a stock checker into one extension. For sellers who want fewer subscriptions, it covers most of the wholesale/OA sourcing workflow in a single tool.

Why I use it
Good value if you'd otherwise pay separately for analysis + IP + stock checking. The stock checker (how many units a competitor is holding) is a quietly powerful wholesale feature most beginners overlook.
