Answer
If you need to make an incentive, sales commission, Director's Fees, Return to Work payment, or any other miscellaneous gross payment to an employee, this can be done as a bonus in the program.
If you are happy to use the label Bonus/Commission, you can edit a bonus directly in-pay by going to the pay run in question, clicking the pencil to edit the employee's pay, then clicking Edit to the right of Bonus/Commission on the right-hand side of the Edit Pays screen.??

Use the plus+ symbol seen to the right to add the bonus into the pay.

Finally, enter the bonus amount and select a tax method from the available ATO options; the date fields are only enabled when a relevant tax method is selected. Here you are able to nominate the payment as Director's Fees or a??Return to Work payment, if relevant, as well as nominate whether the amount will be included in super calculations.

If you would like to change the description from Bonus/Commission to something more personalised, you first need to create the bonus item via Employees >> Allowances/Deductions >> Bonuses??in the program, then follow the steps above to add the newly-named bonus into the pay/s.
