For agencies & aggregators

Every client. One login. Zero crossed wires.

SellerOS is multi-tenant at its core — workspaces, roles and data isolation are the architecture, not an enterprise add-on. Run a portfolio the way you run one account.

Four roles, enforced server-side

Every mutation in SellerOS re-checks permissions on the server — a role isn't a hidden menu, it's a hard boundary.

Owner

Full control including billing and plan changes — the account principal on each client workspace.

Admin

Everything operational: settings, team, keywords, campaigns, repricing — without billing authority.

Analyst

The day-to-day operator role: runs research, keywords, alerts and seller operations, but can't touch settings, team or billing.

Viewer

Read-only. Perfect for clients who want visibility into their own numbers, or junior staff in training — they can see everything and change nothing.

Built for portfolio operations

Org-scoped isolation

Every workspace's data is scoped to its organization at the query layer. Client A's catalog, campaigns and finances are structurally invisible to client B — not hidden by a filter.

Roles that match contracts

Give each teammate exactly the authority their engagement allows. Permission checks run server-side on every mutation — not just hidden buttons.

Client-ready reporting

Every table exports to CSV and the P&L view produces a formal income statement — month-end client reports without spreadsheet surgery.

Read-only client access

Add the client as a Viewer on their own workspace: full transparency into their numbers, zero risk of an accidental repricing change.

Security your due-diligence can cite

Login-with-Amazon OAuth (no seller passwords), AES-256-GCM encryption at rest, TOTP MFA, PII-scrubbed logs — aligned to Amazon's SP-API Data Protection Policy.

Same tools on every plan

Your junior brand and your flagship account use identical tooling — plans scale seats and capacity, not capability. No per-tool upsells across a portfolio.
