Hmm... that may have to wait a bit for the 1.0 release. As of right now, recurring billing is not in core, but the module as is would allow you to make the product free, collect the CC info, and then start charging the card after 1 week. Granted, you'll have to stay on top of cancellations as those aren't automatic at the moment.

Hmm... I guess there are some updates, in that the recurring module is now a part of core. It's primarily a framework for other modules to plug into, and I think there is now a PayPal and an Authorize.net implementation of the recurring stuff. Regarding indefinite membership, I can't remember where we left off... I have a sticky note on my monitor reminding me to comment it out, but I've seen questions in the forums recently asking how to enable it. I wish that hadn't fallen by the wayside.

In any event, I did get your messages before but didn't reply when I saw that you guys had found the solution to that problem yourselves. Feel free to contact me if you have something specific in mind - e-mail or PM is fine.

Thank you for your reply, Ryan.

We've implemented the recurring functionality, but what about the free trial followed by monthly payment, is there anyway to do this, for example, we can let some user apply to this free trial, then we approve it, and give the user a limited period role without paying money, and in this limited period, they can cancel this so that they will avoid paying the bill after the free trial? Thank you.

Best Regards,

The core recurring modules provides for a trial period. Basically, you can just set the product price to $0.00 and then set the recurring fee to whatever you want it to be. Just don't bill the first fee until 7 days after the order is completed.

This modules works best in conjunction w/ some other credit card processing module, but there aren't a lot of payment modules w/ the recurring handler integrated yet.
