You can give any user in Sage HR Online Services administrator access. For example you could add an employee record from Sage 50 Payroll, then edit their permissions to admin.
However, if you want to create an admin user who doesn't need to be linked to an employee record in Sage 50 Payroll, or if that user isn't on the payroll, you can manually add a new user in Sage HR and then assign them admin access.
📎NOTE: Be aware that this can mean you have someone with two profiles in your Sage HR company. So you may want to name the admin profile something different to differentiate it from their non-admin profile.
Add the user as employee in Sage HR.
Don't send their employee record to payroll.
Mark them as not needing to be in payroll within their Sage HR profile.
Change them from Employee to Administrator within their Sage HR profile.
Review your admin settings.
