I built a $19/mo dunning tool because Churn Buster costs $249

The problem If you run a SaaS on Stripe, around 9% of your MRR is silently leaking every month. Cards expire. Banks decline. Customers don't notice. Stripe retries the charge a few times, but it doesn't email your customers. It doesn't warn them their card is about to expire. And by the time you notice, they've already churned. The existing solutions are expensive I looked at the options: Churn Buster : $249/mo minimum Baremetrics Recover : $158/mo Stunning : opaque MRR-based pricing For an indie founder doing $5-25K MRR, spending $150-250/mo on dunning feels wrong. The ROI math works, but the cash flow doesn't. So I built Revenudge Revenudge does three things: 1. Pre-dunning alerts - Detects cards expiring in 30/14/7 days and emails your customers BEFORE the payment fails. This is the killer feature. Stripe doesn't do this. 2. Recovery email sequences - When a payment does fail, sends 3 branded emails (Day 1, 3, 7) with a one-click card update link. Your logo, your colors, your brand.
