Who do you use for your Recurring Billing/Backend?

Sort of on topic. Are there any good revshare affiliate program packages out there so that you can run a revshare affiliate program with your rebill site?
 


So nobody knows of any good revshare affiliate program packages? I'd love to be able to give my affiliates 50% of my rebills. I already have several who are interested.
 
PAYPAL.COM MOTHAFUCKAS!

I use PP as well for a bunch of monthly stuff.

The only problem is that each time it bills the customer - it sends them an email notifying about the payment. It forces them to think about the payment and there is more chance of them cancelling.
