Failed payment recovery with Smart Retries

Turn on ML-timed retries in your billing system, then add your own layer: personal emails for high-value accounts, a CSM alert, and a pause-not-cancel rule.

Building block of the Product-signal expansion engine and Finance ops agent.

1Is this my problem?

Involuntary churn from failed cards is revenue customers never meant to lose.

You'll recognise this if…

Failed card payments churn silently.
No alerts for big accounts.
Manual dunning emails.

Companies affectedSubscription businesses on Stripe. Industries: SaaS. Typical fit: seed to 10 staff to 50 staff.

Cost of doing nothing (estimate)Roughly 1–3 hours a week of manual work stays on the team, and the work is done inconsistently.

2Is this solution worth it?

Limits and when not to build it

Skip it if: Invoice-only billing.

Don't double-email: check Stripe's built-in emails first.

3How does it work?

One small internal tool does this for you. The same job, before and after:

Before · by hand

invoice.payment_failed: someone notices
Smart Retries pick retry times
High-value account?
Personal update-card email
Alert owner
Pause, don't delete

The AI's job here

Stripe's model chooses when to retry based on signals across its network; your layer adds the human touch.

Maturity ladder

What each level adds. Most teams start at level 1 or 2 and climb. Highlighted: where this build sits.

Level 1Basic automation
Trigger: invoice.payment_failed. Fixed rules then smart retries pick retry times, high-value account?, personal update-card email. No AI involved.
Level 2AI-assisted
An LLM handles the judgement step (summarise and draft) and a person reviews every output before it is used.
Level 3Autonomous agent
The agent runs end to end on its own and only stops for exceptions. CSM for key accounts.
Level 4Self-learning system
Becomes part of the product-signal expansion engine: Each alert records what happened next (expanded, churned, ignored).

Level 4 lives in the Product-signal expansion engine: 6 stages with a learning loop.
