Executive Summary

Many small SaaS businesses lose recurring revenue to failed card payments and manual recovery is time-consuming and error-prone; this pain is especially acute for the roughly 500,000 SMB SaaS vendors who can’t afford dedicated payments teams. Recovering even a small percent of monthly churn is high-leverage because it compounds month-to-month on subscription MRR. Build a lightweight service that integrates with Stripe to detect failed payments, run smart retry logic and card updater flows, automate personalized dunning sequences, and surface a simple dashboard and webhook-friendly API for billing systems. Price it as a low flat monthly fee (e.g., $20/mo) rather than a percentage of recovered revenue to appeal to margin-conscious founders. The market is attractive now: estimated TAM ≈ $120M (500k SMBs × $20/mo × 12 months), driven by accelerating subscription adoption, Stripe’s platform ubiquity simplifying integrations, and growing founder appetite for predictable SaaS expenses. Competition is medium, with incumbents often taking a cut of recoveries, so there’s a clear niche for a fixed-fee, developer-friendly product. You can differentiate by deep Stripe-first automation, high deliverability and UX for end customers, and transparent ROI tracking, but expect challenges around compliance, card network rules, inbox deliverability, and convincing customers to migrate from established players. If you can demonstrate reliable recovery rates and simple economics for founders, this is a practical, high-impact SaaS to pursue.
