To set up expenses:
If it is an ongoing expense, (you expect it to happen every pay period), set it up in the employee screen. Set up once-off expenses in the payroll screen.

1. Click on the last row of the elements grid.
2. A drop down will appear.
3. Select 'Expenses'
4. Put the amount of expenses in the Amount column.
5. You can also overwrite 'Expenses' to 'Mileage' etc.

(Make sure the expenses are not being taxed by clicking on the 'Details>>' button at the top right of the grid. 'Tax', 'PRSI' and 'Levy' should all be unticked.)
