I show that therer are diferent host panel and billing program, but could not find the posibility to see they working together.

Anyone know packages that could be seen in a demo or similar?

I see as a probably good billing software the modernbill bill program and also the cpanel and plesk as hosting panel.

Hope that anyone could say me where to see to try to found the best need for my bussiness.

Thanks in advance.

Hsphere is a control panel with integrated billing.
