Add Expenses To A Task
To add an expense to a task, click the + icon or existing task expense value in the Expenses column of the Task List:

Workzone will then open the Expenses tab of the task tray where you can specify the expense amount, expense class, and comments.

Once one or more expenses have been added to a task, the total amount of expenses will appear in the Expesnses column for that task's row.

Click on that amount, and you will be taken to the Add/Edit Expenses page with the individual expense entries for that item.
NOTE: Negative value expense entries are permitted to allow for a “credit” against entries.
