To create a Non-Payroll user:
Log in to ESS as an Administrator.
Go to Teams.
Select the New Starters team.
Click on the + (plus) button. If the button doesn't appear, you can change this in Settings, Roles & Permissions.
Complete Basic Details.
Tick Is a non-payroll user.
Click Next.
Click Add non-payroll user.
Search for the non-payroll user you created.
Select Teams & Roles. The user will automatically be assigned to an Administrator role.
To remove, select the ellipsis button on the Administrator row.
Select Remove Administrator role.
To activate the user, select Account Settings.
Click Activate.
