Hosting with centos panel

Hello,

I'm just curious if there is any set up information/tutorials available to use centos-panel to sell shared hosting.Im able to set up packages etc but is there some sort of bridge that sets up clients accounts, like billing software.

Idea:

i set up x amount of packages,
the buyer wants to buy x package,
so im thinking of a sign up page or automation for this process that payment received the said package is allocated the user.(similar to whmcs)

If this is available could i get some pointers in the right direction.

Well if you can not delete an account , create without trouble it is not useful
I never use it for real work it is still so buggy but like the panel and just keep waiting until it becomes better
