I'm planning to use a bunch of WPMUdev plugins to get my paid Multisite network up and running. The business model that I'm looking to create looks like this:
"Pay $X.xx up front, get 6 months free. After that, $Z.zz per month".
The Pro Sites plugin is obviously useful and the WHMCS Multisite provisioning is very interesting as well.
I'm currently under the impression that I'll need to write my own custom extension for the ProSites plugin to get the functionality I want but I wanted to double-check that it's not already possible with me missing it before I start coding that. (Additional note: rather than membership levels, I want a simple single cost for all users that's the same with all users having the same access to features).
