Looking for a CRM to manage a community w/ recurring payments

Hi everyone,

I've searched far and wide, and maybe I'm just using the wrong keywords or terms.

I'm looking for a CRM software to accommodate a community that I am building on Circle. The community is paid, so I would love for the software to be integrated with a payment processor like Stripe. Also, I would like there to be single sign-on possibilities so that I can embed Circle on my log-in-based website. Finally, I also need it to be easy to manage recurring events with it.

So far I've tried MembershipWorks, but they don't have single sign-on. Outseta doesn't have event management. Maybe some solution has all the pieces?

Is this too much to ask of a single software solution?

Thank you guys.
