Time entries can be Billable, Costable or both. Billable time is borne by the client and added to project billing. Costable time is borne by you and added to project cost. Time entries are automatically marked Billable and/or Costable as described below.

The manager can change the Costable/Billable attribute during approval. It is important to note that project cost/billing is updated only when the time entry is approved.

Billable Time = Billing Rate of the time code on the date of the time entry * hours filled in the time entry.

Costable Time = User Cost Rate for the date of the time entry * hours filled in the time entry.

	Tip
	It is beneficial to create a time code which is Costable but not Billable. For example, this can be used to fill time which has exceeded the planned hours of a task. This will help you understand the amount you could have billed the client had you estimated correctly.
