About TheSeller.app
TheSeller.app is a suite of focused apps for Amazon FBA sellers. One app, one job, done well. Free entry point, fair pricing, read-only access. Built in the European Union by a small team that's tired of bloated tools.
The Amazon FBA tooling market is full of all-in-one suites that try to be a keyword tool, a profit dashboard, a PPC manager, an inventory planner and a review tracker — all at once. You pay for forty features and use four. The bill is bigger than the value.
We don't believe in that. We believe a seller is better off with a small set of sharp tools, where each one does one job exceptionally well, and you pay only for the jobs you actually do.
EasyBoard, our first app, does the most important job: tells you how much you really made on Amazon last month — after every fee, FBA cost, storage charge, refund and ad dollar. One number. One screen. No spreadsheets.
More apps are on the way. Each one will follow the same rule: one job, done well.
Six commitments that shape every decision we make about the product.
Our apps never write to your Amazon account. We can't change listings, prices, inventory, or send messages to buyers — and we wouldn't want to be able to.
When Amazon hasn't returned a number yet, we show a dash. We never invent a percentage to hide the gap. Fake numbers lead to wrong decisions.
Primary data lives in the European Union with strict isolation between accounts. No third-party developer or contractor has access to your data.
The Free plan is permanent. Paid plans add scale, not a different product. No per-seat tricks, no hidden add-ons, no annual lock-in.
The same small team writes the code, holds the keys, and answers your support email. No outsourced support. No random contractors with access to your data.
We'd rather delay a feature than ship one that misleads sellers about their numbers. New features go through a supervised rollout before they reach everyone.
Three honest answers to the questions sellers care about. Full detail on the Security page.
On managed European servers, encrypted at rest and in transit. Backups are encrypted and rotated out within 90 days.
Your data is isolated from other accounts at the database level. Access tokens are encrypted with a key kept separately from the database.
Only the small team running TheSeller.app, all on mandatory two-factor authentication. We never sell, share, or train AI on your data.
We answer real emails. No support bot, no ticket loop, no first-line offshoring.
