MultiSite client usage

Hello WPMUDEV and users

I am running a MultiSite installation where i host client websites. I am offering different monthly packages. With limitations to disk space and bandwith. The more disk space they need or bandwith they need then they have to upgrade to a higher package.

If the are in the highest package and they need more disk space or bandwith then i offer a per GB over usage price.

Is there a way or plugin to track the disk space and bandwith per subsite? And a way to limit the disk space and bandwith per subsite?

Regards, Guido
