There are two ways to make someone an admin, depending on whether they already exist in the system.
Option 1: The user already exists (e.g. synced via an integration)
If the person was already imported through an HRIS integration, they'll show up in your employee list - you just need to change their role.
Go to Employees > Manage Users (https://app.comprehensive.io/company/employees/manage)
Find the user in the list
Change their role to Admin
They'll now have full admin access
Option 2: Invite a brand new admin
If the person doesn't exist in Comprehensive yet, you'll need to invite them.
Go to either:
Onboarding page → click the "Invite other admins" card in the Account section
Manage Users page → click "Invite admins to Comprehensive"
Enter their email address and full name (you can add multiple at once)
Click Send invites
They'll receive an email with a login link - once they accept, they're in as a full admin
Good to know
All admins have equal permissions - there's no "super admin" vs. regular admin distinction
Any existing admin can invite or promote additional admins
If someone was synced from an integration, you don't need to re-invite them - just update their role
