FAQ

Common questions from Amazon sellers

Does Sellerio replace Seller Central, or sit alongside it?
Alongside it. Sellerio connects through Amazon's official SP-API and Ads API, so your Seller Central account stays exactly where it is — Sellerio just gives you a profit-first view of it.
Is my Amazon login safe?
Yes — every account connects through Amazon's own Login with Amazon consent flow. Sellerio never asks for or stores your Seller Central password, and every credential is scoped to your organization at the database level.
What does the Bid Optimizer actually change?
It moves bids toward the breakeven ACOS computed per keyword from your real COGS and Amazon's fee slabs — with hard floor, ceiling, and max-per-step guardrails enforced server-side, so nothing runs away unsupervised.
Can I run multiple Amazon accounts under one login?
Yes — Organization Workspaces let you connect several Amazon Seller Central and Ads accounts under one roof, fully isolated from each other, with one combined view when you want it.
