Prior to this, we had to chase up manually on credit cards that had failed. Our account managers found this process to be the most difficult and it took a long time to fix. Ever since we put dunning workflows into play, we believe that we have lightened the load on finance. The Stripe failure codes we encounter define the specific retry logic and email sequences that we follow, enabling us to always know what happens next. Our gateway implementation was easy and does not fail either. It's really helped to speed up our weekly billing sync not having to go through logs to understand exactly where the customer is in the recovery life cycle.
