Great Product, Excellent Support!
We have used Billings Pro and Billings Pro Server self serve for almost 4 year now. It is hosted locally (BPS), and syncs with 5 computers (BP) and several iPhones. It delivers on it promise and support has be super helpful, friendly and effective. Note: A networked version syncing with several computers and mobile devices requires some finesse in the set up. Once its set up right, it is excellent. Highly recommend Billings Pro for any creative services company!
