I ended up making the switch about a week ago. I had been in contact with Matt on and off about converting from CE 3 and I just cannot wait for features to be added to CE that already are and have been standardized in WHMCS. As much as I like our helpdesk software, having both billing and helpdesk together in a single area is worth more to me than having separate logins.

I was waiting for CE 3.1 to come out, but I've found myself waiting on software releases before to only have them delayed time and time again. I am certain CE will eventually deliver on this release, but there's not even a real ETA at the moment since they've just begun the alpha phase of testing.

The switch has been painless and I'm excited to finally get to see and work with the admin. side of WHMCS. It's much easier to navigate and I already like it better than CE.
