How can I add incentives or commissions for my employees every month?

You can add incentives, bonuses or commissions to your employees while processing your monthly pay runs.

Go to the Pay Runs tab.
Click Create Pay Run or View Details if you already have a draft pay run.
Click next to the employee name and click +New Earning from the side panel.
Choose the incentive/ bonus/ commission from the drop down and enter an amount. You have to configure the component through Settings > Salary Components for it to show up here.
Click Save.

The incentive / commission will be added to the employee’s pay for that pay period.
