We're looking a a recurring billing and subscription management service. I've narrowed it down to Spreedly and Subscription Bridge. Spreedly is a bit bare bones but pretty easy to use. And they seem to have been around longer and have the kinks ironed out.
Subscription Bridge is about the same price ($50/m if we use their gateway) and has the following benefits (which spreedly does not):
Since Subscription Bridge is a bit new, I've love to hear from existing customers.
What about recurly? Dunning management seems pretty solid.
If you need something more complex that deals with multiple channels, consider Aria systems.
Sadly, I'd have to say I would not, at least at this time.
Turns out Subscription bridge has some show stoppers for us (which I think they are finally changing). Like, you couldn't include a single click link to Cancel your subscription. You had to copy your ID (which is in the email) and then click a link in the email and paste the ID.).
