I need to integrate CCBill, Drupal 6.9 and the ability to limit customer access to sites based on whether they are paying memebrs or not. The way I foresee doing this is to have their role dynamically changed within drupal when they have successfully completed a payment. I will also need auto renewal, etc.. For the admins/managers of this site, can your software do this successfully? To anyone else, has anyone successfully done something similar?
