I have seen plenty of debates about this on the internet, but I would like some advice based on experience as opposed to comparing feature lists. Before I go into detail, I would like to make it clear that I am asking for opinions on WHMCS and ClientExec, and not Modernbill or any other billing software.
Currently, I run ClientExec - I don't have a problem with it, but I am interested in seeing why people have chosen WHMCS over ClientExec and vice-versa. If you are a client of a web host, and have used different hosts using both systems, then I would also like to hear from you!
I am particularly interested in:-
* Customer Experience
* Ease of use (WHMCS from an admin perspective, both from a client perspective)
