Failed payment recovery for an online course business
Failed Mollie and Stripe payments are spotted, matched to the customer, retried on a schedule and logged. Cancelled subscriptions are tracked too.
The problem
Failed payments and cancellations were only noticed weeks later, so money slipped away and customers lost access without anyone getting in touch.
What I built
Payment fails→Find customer→Retry→Log result
- Failed Mollie payments are checked on a schedule.
- The customer is found and matched in Systeme.io.
- Retries run through the payment API, with a route for each result.
- Every attempt and result is logged in Google Sheets.
- Separate flows track failed payments and cancelled subscriptions in Stripe.


Failed payments retried automaticallyFailed payments get followed up the same day instead of being found weeks later.
