1. A cash consultation is just a combination of a private invoice and receipt in the one. Click Reception->Cash Consultation and bill the patient out as you have previously for other invoices.
2. Once you click OK you will be taken to the Payment Details screen. As for a Private Receipt, fill out the details as necessary. If you want to only charge the patient a portion of the amount owing, simply type in the amount they are paying and tick Patient Contribution.
