Failed Payment Recovery Churn
Subscription businesses lose recurring revenue when failed payments silently churn customers because default retries and dunning emails fail to recover them.
In their words
how are you dealing with failed subscription payments (expired cards, insufficient funds, etc.)?
Often cards expire or some reason Stripe turns off automatic payments. Then I randomly check every so often and see a lot of unpaid.
we were losing revenue for months before I noticed - Stripe wasn't throwing errors, payments were just silently failing
I'm so tired of having to have failed payment email flows with several branches because I'm checking if they're shop pay or not
I get to the checkout line and swipe my card....IT EXPIRED YESTERDAY!!!
en cuanto la Order queda en estado failed, se cierra en firme
Only 3 of those got successfully auto-charged, 7 got rejected citing "Technical Error".
We collect payments on the due date around 7am, but then he decides to go into the account and pay again about mid day
We were re-charging customers when the original charge had cleared but our system hadn't gotten the confirmation in time.
They sign up for the trial, and their cards decline at the end, most of the trials end up declining.
I often have trials that turn are cancelled due to billing errors
as soon as we tried to sign them up to a direct debits, they dropped out
Do you know of any EU payment processor that supports recurring payments like a SaaS would need (subscriptions, subscription state tracking, automatic retries of failed payments)?
after i refunded / cancelled, 9 days later they were able to charge again

Tools they use today
- Stripe
- Razorpay
- Paddle
- PaymentKit
- GoHighLevel
- PayPal
- Shopify
- Mercado Pago
Why those fall short
- no pre-renewal reminder or self-serve refund flow
- system lets them try as many times as they want
- failed Order closes permanently, no retry on same order
- No expiry warning; digital card not accepted in most stores
- edge cases still turn into operational work
