# The Best Failed Payment Recovery Tools in 2026 (by Platform and Budget)

> Churnkey, Churn Buster, Stunning, Paddle Retain, and Snagr compared — pricing, platform fit, and which failed payment recovery tool makes sense at your MRR.

Failed payments cause 20–40% of subscription churn, and most of it is recoverable — the customer never decided to leave; their card did.[1] The tooling market splits cleanly by billing platform and by budget, so the honest way to compare recovery tools is to start with what you sell on and what you can spend.

## Quick picks

- **On Stripe, $30K+ MRR:** Churnkey or Churn Buster.
- **On Stripe, early stage:** Stunning.
- **On Paddle:** Paddle Retain (built in).
- **On Polar.sh:** Snagr — the only recovery tool built natively for Polar.

## Churnkey — best for mid-market Stripe SaaS

Churnkey combines payment recovery with cancellation flows and retention offers. It is polished, well-regarded, and priced for companies with real churn volume: plans start around **$199–$250/month** and scale with MRR.[2] If you are doing $30K+ MRR on Stripe, the math usually works. Below that, the subscription costs more than it recovers.

## Churn Buster — best for high-volume subscriptions

Churn Buster focuses squarely on failed-payment recovery for subscription businesses, including ecommerce subscriptions. Pricing starts around **$249/month**.[3] Strong campaign tooling and deliverability, same caveat as Churnkey: it is priced for scale.

## Stunning — best budget option for Stripe

Stunning has been doing Stripe dunning for over a decade and is priced for smaller businesses. Stripe-only, which is fine if that is your stack and useless if it is not.

## Paddle Retain — best if you’re already on Paddle

Retain (formerly ProfitWell Retain) ships with Paddle’s merchant of record platform. If Paddle is your MoR, use it — it is integrated and priced on recovered revenue. It is not available off-platform.

## Snagr — best (and only) native option for Polar.sh

Everything above assumes Stripe or Paddle. If you sell through [Polar.sh](https://polar.sh), none of those tools understands your billing events. [Snagr](/) connects to a Polar organization in one OAuth click and covers all three revenue-loss events — failed renewals, abandoned checkouts, and cancellations — with automatic email sequences.

- **Free tier:** 50 recovery emails/month, all three sequence types, full analytics — no card required.
- **Pro:** $19/month flat. Unlimited emails, custom sending domain (DKIM/SPF/DMARC), editable templates. No revenue share.
- **Honest measurement:** a built-in 5% holdback control group reports incremental lift, not just raw recoveries — most tools on this list report gross numbers that include customers who would have fixed their card anyway.

Watch the pricing model

Recovery tools price three ways: flat monthly (Snagr, Stunning), MRR-scaled subscription (Churnkey, Churn Buster), or a percentage of recovered revenue (Retain, and Lemon Squeezy’s built-in cart recovery at 5%). Percentage pricing feels safe but taxes your best outcome — the more it recovers, the more you pay, forever.

## How to choose

Start from your platform — it eliminates most of the list. Then estimate your monthly failed-payment volume from your billing dashboard and require that the tool cost clearly less than a conservative 30% recovery of that number. Finally, prefer tools that measure lift against a control group; without one, you cannot tell recoveries you caused from recoveries that would have happened anyway.
