I am going to trial electronic billing service for: WPA, Aetna Global, Vitality, Allianz and Aviva.
Patients wanting to have me bill for them will be liable for any unpaid charges if there is a difference between the billing value and what is paid by the company and this has been added to my service use terms and conditions. You of course can go ahead and use payment receipts as usual!
I am putting together an app which will have your account balance available so you will know what is owed. Keep posted for more details!
