How can i set employees salary amount?
In fact, setting up a payslip earnings item for salaries does not allow you to determine and enter employees’ salaries. It only provides a method for making entries on payslips. You must still calculate the earnings amount for each payslip.
If an employee has a fixed salary, the easiest thing to do is set up a recurring payslip: https://www.manager.io/guides/9753. You can also clone previous payslips.
