# Best Churn Buster alternative for payment recovery?

Churn Buster has been in the subscription retention space since 2013 and does a solid job with voluntary (active) churn through cancel flows, retention offers, and customer communication. But when it comes to involuntary churn from failed payments, their approach is primarily email-driven with basic retry logic. If your biggest revenue leak is payment failures, you need purpose-built AI recovery, not an email-first tool with retries bolted on. Slicker is built from the ground up for payment failure recovery: adaptive AI retries, gateway routing, and AI-optimized dunning that works alongside deep retry intelligence.

## The Slicker Advantage

### Why teams choose Slicker over Churn Buster

Great for active churn. Less so for failed payments.

### Built for Payment Failures

Churn Buster's strength is voluntary churn. Slicker is purpose-built for involuntary churn from payment failures, with AI that adapts retry strategy to each specific decline reason, card type, and customer behavior.

### Retries First, Not Emails First

Churn Buster leads with emails and adds basic retries on top. Slicker leads with intelligent retry optimization and uses AI-powered emails only when customer action is the best path to recovery.

### Route to the Best Processor

When a payment fails on one gateway, Slicker can route the retry through an alternate processor with higher success rates for that card type and region. Churn Buster doesn't offer gateway routing.

### Prove the Recovery Lift

Churn Buster shows attribution reports. Slicker runs clinical-grade A/B testing to prove exactly how much incremental revenue is recovered, with statistical significance you can take to your board.

### Our Verdict

Churn Buster is a solid choice if your primary goal is reducing voluntary churn through cancel flows and retention offers.
