What are the billing options compatible with ISPmanager?

Question

Billing systems

Is there anything else besides BILLmanager that works with ISPmanager Pro 4?
The goal is to sell hosting and related services (both one-time, such as an hour of help / install CMS such and such, and permanent, such as a month of support).
