After completion of work for a client, you may want to bill a different number of hours than were actually needed. You could, for example, be charging the client a flat fee for the work, regardless of the number of hours worked. You may also have an employee working on the the task who is undergoing training, so will likely take longer than normal for the activity.

To monitor efficiency, you can record the actual number of hours worked on a task in the Actual Hours field in a billing item. This field is shown below the Amount section for a Billing Item and is for your use only--it will not appear in any invoice.

You can show this field in reports and export the information for an analysis of hours worked vs. hours billed.
