I recommend hawk-i (www.hawk-i.com) for this sort of project. It is internet billing software for small to mid-sized Internet service providers. It has a great web admin service and customers can view account history, pay bills, and manage their accounts via the web interface...
I am sure that you are looking for something similar to this product...
We have been using it almost 4 years now and we couldn't ask for better support and service...
Just my opinion though.
