###Billing using Time Logs

* If you wish to bill against a Time Log you need to select the 'Billable' option.

* In the costing section, the system will pull up the Costing & Billing rate from [Activity Cost]({{docs_base_url}}/user/guides/projects/activity-cost.html) 
	based on the Employee and Activity Type specified.

* The system shall then calculate the Costing and Billing amount based on the Hours mentioned in the Time Log.

* If 'Billable' is not selected, the system shall display the 'Billing Amount' as 0.
