I notice that all site use same billing software bluehost.com, hostmonster.com, fatcow.com, ipage.com i want know which billing software they are using?
Yes, WHMCS, is a good choice. Just that, in case we have any complaints/queries, their Support system is not that prompt to answer & assist. Too slow often.
Some companies have been using Host Bill and have found it better than WHMCS, however it still needs more features.
Well WHMCS is the best tool. Heres WHY: General Reasons: It has a long list of modules Awesome support Affordable etc etc u know them But Best features: It is not just limited to web hosting, but can be integrated into any billing system. It can serve as centralized billing system if you are providing multiple services. Gives user the freedom he seeks. Visit its plugin library and you will know that nothing is impossible with WHMCS. WHMCS has now been taken over by cPanel and you know that is a very good news as webhosting these days cannot be done without cPanel It has got regular updates and upgrades. Personally I feel that WHMCS is already few years ahead and the current updates are only an added advantage.
hostbillapp.com looks very nice but has extremely bad customer service I recommend to avoid these polish people
yes most people use WHMCS Including myself it really awesome, but i don't think the big companies are using WHMCS, they might be if it is heavily modified but it seems those are kinda custom made softwares
