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.
I use Chargify.com very good API great features and excellent support
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.).
