WHMCS or HostBill?

[Tyler]

Until HostBill supports "Post2Host", I will stick with WHMCS and its large selection of community addons. No matter how complete a billing system is, there are always missing features that some must consider a deal breaker.

Seeing as almost all of the large Post2Host sites have pretty much died out in the last year or two because people would rather spend $2 a month for shared hosting, there's not much point in such a module IMHO. That being said, you're always free to script your own Post2Host module -- nobody is stopping you. There's no reason to fault the billing system just because it doesn't come with a Post2Host module by default.

i do use WHMCS and Hostbill as well.
I may feel that WHMCS is more user friendly and more flexible while you can find out that lot of this topic in other forum .
And most of them support WHMCS more than Hostbill.

I have one WHMCS and one HostBill. As many people think, I'll vote for WHMCS, but HostBill has enough features if you really don't have enough money to pay for WHMCS license.
