Hi there.
I am after a efficient way of managing hosting and domain names so that I can keep track of the billing and the renwal side of it. Does any one know of any software that can do just that.

phpManager is a common package that many hosts use to manage customers. If you are looking for actual accounting software, I would recommend QuickBooks.

The most seen choices here are modernbill, phpmanager, and webhostingbilling along with ubersmith.
