I have a web app that I'm currently selling online using ClientExec. I want to get away from ClientExec and use something like Chargify/Spreedly/etc. for the billing part, however my problem is how can I create each users account?
ClientExec currently creates a new cPanel account and subdomain for each user, which is nice, but overkill. My customers don't need access to that.
Can I setup subdomains using PHP?
How can I limit the users bandwidth and storage space?
Can this be done? Is there an app for this already?
