I'm the not the usual kind of clientexec client.
I'm running the technical side of an up-and-coming ISP and have finally convinced our billing department to move away from their aspx/client-side-exe system, to a web-powered PHP application.

Clientexec seems to be working so far and after having removed all the "web-hosting specific" features from it, I'm fairly happy and ready to move across the client database.

Anyone else using clientexec for something like this? If not, what do you use and why?

Well clientexec is really good for backend control but the order form is quite irritating it costed us 300$ for a custom template and some modifications on the template and order form.

I've used clientexec once, and I never really liked it.. it takes far to long to purchase hosting, with so many things to go through, sometimes it may even be difficult..

I have try it, It ok. If you want some think that work, try WHMAP or MB.
