Better dunning management and smart logic to retry failed cards and autocorrect expiration dates. Also ability to set rebill time periods (3 days, 7 days, 10 days) later instead of retry on day 1, 2, 3, etc. Also, ability to customize a personal email message for each of the retries. Also, ability to set different email messages for various types of declines (failed card, expired expiration, expiration date approaching, etc.), In sum, more value added features for subscription management. Right now the offering is sparse.
