DrupalCon Denver 2012: RECURRING BILLING IS HARD, IS HARD, IS HARD.

This talk focuses on the complexities of building an effective recurring billing system, highlighting that it involves much more than merely charging a credit card each month. The speaker discusses the challenges of securely storing credit card information while ensuring PCI compliance, managing billing intervals, and handling dunning processes. Additionally, the session covers generating key account metrics, implementing discounts, and the best practices for testing new features in a subscription model. While primarily using Drupal as a case study, the insights shared are applicable for developers working with any platform, including Ubercart and Drupal Commerce.
