How do I configure the role ‘superadmin’ to a user in Zoho Books?

A superadmin in Zoho Books is essentially the owner of the organization. This role has unrestricted access to all modules and settings within the application. Unlike other roles, the superadmin role cannot be assigned to other users because it is inherently tied to the ownership of the organization.

However, rolewise a superadmin is same as the admin. The user who has been invited with an admin role will have unrestricted access to all modules.

Instead, you can invite the user and provide them admin access. Read more about inviting users to your organization.
