Serious seller analysis should be easier to access.
SellerHub gives Amazon sellers focused tools for decisions that usually require scattered spreadsheets, manual checks, or another subscription. The tools are available free and run directly in the browser.
Why we built it
A clear answer is more useful than another dashboard.
Amazon sellers work across advertising reports, listing drafts, fee assumptions, settlements, inventory files, and operational exports. SellerHub turns those inputs into focused answers: what changed, what deserves review, and what the underlying calculation means.
There is no Seller Central connection, account requirement, or hidden feature tier. You bring the relevant report or assumptions, review the result, and export what you need.
What every SellerHub tool should do
Keep report contents private
Supported files are parsed on the device. The current application does not send their contents to an application server.
Explain the result
Flags, formulas, thresholds, and assumptions should be visible enough for a seller to review—not treated as a black-box verdict.
Stay honest about limits
Estimates are labeled as estimates. Audit signals are investigation starting points, not proof of reimbursement eligibility, accounting errors, or future performance.
Who operates it
Built and maintained by OrbitBy.
