The "Client Billing" menu item.

Once you have completed and signed a Client session that contains a "Billable Service" (covered here), the finished session will show up on the "Client Billing" screen accessible via the left hand menu.

Clicking on the pending session will take you to a screen where you can choose the sessions (if there is more than one pending for that Client) that you would like added to the bill.

From this screen, you can add any additional notes that you need to add to the bill and select when the bill is due; 15, 30, 45, 60, 90, or 120 days. Click "Save" to create the bill.

After the bill is created, you have multiple options on how you can send the bill to the Client or the insurance provider covered in the following help topics.
