not that friendly. i applied to their special branded merchant account and was denied due to low volume.
Recently been thinking of changing to Chargify now that they support a payment gateway in Scandinavia. We (http://beaconpush.com, push service for Web Sockets) currently have our custom-built system for recurring payments. It works, but I really don't want to spend time hacking on it. I rather be focusing on our core business of developing our service.
