Yeah me too, WHMCS is the best one i think, but if you want a free one
Maybe PHP Coin or Solid-State, or if it doesnt matter the design, you also can use some script named Cpanel Account Generator or something like that, is in HotScripts
You can also try reseller hosting providers that offer free client billing software.
Thats a great suggestion! There are a tun of host that now offer ClientExec for free or for a low fee. I currently am using ClientExec and have no issues with it.
I agree with the others when they say if you can't afford a billing script, than you might want to go over your business plan again... billing is one of the most important aspects of any hosting company. You gotta bill your clients if you want to get paid!
