Owner or admin edits organization name and branding on Settings → Organization. This is not Billing, and it is not a sender seat.
Edit name and branding
The type badge can read Agency, Client, or Internal. You do not change that type on this form. Members see a read-only page and "Owner or admin required to edit organization settings."
Sign in as Owner or admin.
Open Settings → Organization.
If you see "No organization linked to this workspace.", there is nothing to edit yet.
Change Name (placeholder "Organization name").
In Branding, set Brand name, Logo URL, Primary color, and Brand domain if you use them. Brand name says "Shown to clients when branding is enabled".
Select Save. The page flashes "Organization saved."
Primary color uses a hex such as #73d8e8. Brand domain is a host such as example.com.
What this is not
Organization is not the Business plan. Seats and tokens stay on Settings → Billing. Workspace name and timezone stay on Settings → General. Switching workspaces stays on Settings → Workspaces.
