Some churn was never a decision
A failed card isn't a customer leaving — it's a customer who's about to leave by accident. WhyLeft spots it and gives them a capped, non-annoying way to fix it.
Capped reminder sequence
A hard limit on how many messages anyone receives. Someone whose card expired needs a nudge, not a drip campaign.
Recovered
Revenue you never lost
The sequence ends
No further contact
A failed card is not a decision to leave — so it is never counted as churn, and never sent an exit interview. Recovered revenue is reported separately from win-backs.
Detection is always on
Failed payments and at-risk revenue show up in your dashboard whether or not you turn the emails on. You can see the problem before you decide how to handle it.

Kept separate from real churn
Involuntary churn is a billing problem, voluntary churn is a product problem, and mixing them corrupts both numbers. WhyLeft keeps them apart.
Why this sits next to exit interviews
A meaningful share of what most SaaS businesses count as churn is nothing more than an expired card. It's the cheapest revenue you will ever recover, and it needs no product work at all.
More detail
It also distorts everything else. If involuntary churn is folded into your churn rate, your churn rate is partly a measure of card expiry dates — and the exit interview data you're reading is diluted with people who never chose to leave.
Four providers detected with no code
Failed payments are detected here too — and routed to Payment Recovery instead of counted as a decision to leave.
The month you found free money
You look at at-risk revenue for the first time and find several hundred dollars of MRR sitting in failed payments — customers who are still using the product and have no idea anything is wrong.
Questions about this
Which billing providers work with WhyLeft?
Stripe, Polar, Lemon Squeezy and Paddle are detected automatically — connect the account and cancellations start flowing.
Anything else works through the API, an outbound webhook from your own backend, manual entry, or a CSV import. The billing provider is a convenience, not a requirement.
What access does WhyLeft have to my Stripe account?
Read-only, and narrowly scoped. WhyLeft uses the connection to detect cancellations and look up the cancelled customer's email address. It never reads card data, never moves money, and never modifies anything in your account.
