CardChase: failed-charge recovery

Finds failed subscription charges and runs dunning for small teams

Problem

Indie developers and small subscription businesses often lose customers silently when a card expires or hits its limit; Stripe exposes failed invoice events, but small teams lack a ready recovery flow and message templates, so they only notice after MRR drops.

Solution

Connect Stripe or Paddle, automatically listen for payment-failure events, and run a stepped email/SMS sequence based on failure reason and timing with a card-update link. Show a recovery dashboard and per-campaign performance.

Users

Indie SaaS developers and small subscription businesses on Stripe or Paddle

MVP

Stripe OAuth connect; list failed charges with reasons; 2–3 built-in recovery email templates with card-update links; send log and recovery tagging; a simple recovery-rate dashboard

Revenue

Monthly subscription tiered by recovered revenue or subscriber count; first 5 recoveries free

Why now

Subscription micro-teams keep growing and payment APIs are open enough that an indie dev can wire up Stripe and validate in a weekend
