Number of Clients, Sites, etc for the License Addon
I'm making a website CMS and I'm of course using my licensing add on to sell licenses for that CMS I'm developing. I'd like to do something like you guys do with the different tiers that allow a certain number of clients.. in my case it's for radio stations, so I'd want to say a certain number of stations per cluster license. How would I implement that and then have them auto upgrade to the next plan once it's reached? It would be nice if even WHMCS would share some examples. For example for client limits, look at the WHMCS pricing page. I'd like to do something like this, and think it would be very beneficial for the WHMCS Licensing Add on.
I've already built a license status page much like the one you see in the admin panel of WHMCS
