I just finished building part of our billing system that signs up users for subscriptions. We're using metered billing and that part of our service doesn't report anything yet, but so far using chargify has been a great experience. We don't need to hold CC stuff. We don't deal with dunning. We don't do anything except tell chargify how much our user has used and give them users credentials. It seems to work very well.
