You can set tasks to be billable or not, depending on your individual requirements.

Below is a screenshot of some tasks from the whiteboard - the billable tasks are represented by the green triangle:

You can switch a task between billable or not within your 'Parameter' settings ("SETTINGS" > "PARAMETERS"). Search for the parameter name & select the 'pencil' icon to edit the parameter:

You can then toggle the Billing switch to ON or OFF, & finally click "UPDATE":

Once a task is checked off as completed, the billable charge will be sent to your billing pdf, or directly to the patient's bill in integrated EMRs.
