¿there is some tool like WHMCS but ispconfig FREE and compatible? a friend told me yes and I'm curious to know
What exactly are you looking for? A billing module for ISPConfig? Take a look here: http://www.ispconfig.org/ispconfig-3/ispconfig-3-billing-module/
has an external store the customer can choose the plans while registering? this tool is very impressive
There is no shopping cart system available yet. But the billing module has a api so that you can intergarte it directly into your existing hosting website.
