If you are connected to a payroll platform, as an admin or owner, you have the ability to add pay categories in Employment Hero by navigating to:
Payroll Settings > Pay Categories
On this page there is an option to "Update from payroll" which will pull in any pay categories you have stored within you payroll platform. It will also disable or delete any categories that have been removed from your payroll platform since the last update. Once you've imported your pay categories, you can then begin to assign it to your employees.
