How to Eliminate Payment Churn

Payment related churn exists. Credit cards expire every few years so unless you're using a payment provider that automatically updates credit cards through the credit network like Stripe would do, you will eventually attempt to charge an expired card. A company cancelling their subscription with you might just be trying to tie up loose ends and or stop operating altogether. This happens particularly often in the freelancing world where people stop their freelance work to take a full-time job. You might even be seeing a consequence of how much value you've been providing when somebody churns.
