Best Dunning Software for SaaS in 2026
An honest comparison of 7 tools. No affiliate links, no sponsored placements.
Why this list exists
Every SaaS loses revenue to failed payments. Cards expire, banks decline charges, accounts run dry. The industry average is 9% of MRR lost to involuntary churn. That is $900/mo at $10K MRR, or $10,800/year walking out the door.
Dunning software catches those failures and recovers the revenue. But the market is confusing. Some tools charge $19/mo, others $249/mo. Some take a percentage of recovered revenue. Some focus on recovery, others on prevention.
This guide compares the actual options available in 2026, with honest notes on who each tool is built for. We include Revenudge (our product) in the list because we think it belongs, but we are upfront about the comparison.

1. Revenudge ($19-79/mo)
Revenudge is a flat-fee dunning tool built for indie SaaS founders on Stripe. It handles both pre-dunning (catching expiring cards at 30, 14, and 7 days) and recovery emails after a payment fails.
The pitch is simple: same outcome as Churn Buster at a fraction of the price. You connect your Stripe account, and it starts monitoring subscriptions immediately. Emails are branded with your company name and colors. Customers update their card on a one-click page.
- •Strengths: Pre-dunning included at every tier. Flat fee means you keep 100% of recovered revenue. Built specifically for Stripe.
- •Limitations: Stripe only (no Paddle, Braintree, or Recurly). No cancel flow or churn surveys.
- •Pricing: Starter $19/mo (up to $5K MRR), Growth $39/mo (up to $25K MRR), Scale $79/mo (up to $100K MRR). 14-day free trial.
Disclosure: Revenudge is our product. We include it because we genuinely believe it fills a gap in the market, but you should evaluate it alongside the others.
2. Churn Buster (from $99/mo)
Churn Buster is the most established dunning tool in the market. It has been around for years and is used by well-known SaaS companies. The product is polished, the analytics are deep, and the team clearly knows what they are doing.
- •Strengths: Mature product with proven recovery rates. Detailed analytics and A/B testing. Strong reputation.
- •Limitations: Starts at $99/mo, which is steep for indie founders. Pre-dunning is not the focus. Designed for larger teams.
- •Best for: SaaS businesses above $50K MRR where the cost is easily justified by recovered revenue.
3. Baremetrics Recover ($158/mo)
Baremetrics Recover is the dunning module within the larger Baremetrics analytics suite. If you already use Baremetrics for MRR tracking, adding Recover makes sense since the data is already connected.
- •Strengths: Tight integration with Baremetrics analytics. Good recovery email editor.
- •Limitations: No pre-dunning. $158/mo is hard to justify as a standalone dunning tool. Requires Baremetrics subscription.
- •Best for: Teams already paying for Baremetrics who want to add recovery.
4. MRRSaver ($49/mo)
MRRSaver sits in the middle ground. It has pre-dunning, recovery emails, and a cancel flow feature. The price is reasonable for its feature set, and it works with multiple payment processors.
- •Strengths: Pre-dunning plus cancel flow at $49/mo. Multiple gateway support.
- •Limitations: Less polished UI than Churn Buster. Fewer integrations.
- •Best for: SaaS founders who want pre-dunning + cancel surveys in one tool.
5. ChurnWard ($29/mo)
ChurnWard is a budget dunning tool that covers the basics well. At $29/mo flat, it is accessible for early-stage founders. The feature set is simpler than MRRSaver or Churn Buster, but it handles the core recovery flow.
- •Strengths: Affordable flat fee. Simple setup.
- •Limitations: Basic pre-dunning. Less customizable email templates. Smaller team and slower updates.
- •Best for: Founders who want basic dunning without spending much.
6. FlyCode (performance-based pricing)
FlyCode takes a percentage of every dollar they recover for you. The appeal is clear: you only pay when it works. But the math gets expensive fast. If you recover $2,000/mo and they take 10%, that is $200/mo, more than most flat-fee tools.
- •Strengths: No upfront cost. Pay only for results.
- •Limitations: Gets expensive at scale. No pre-dunning. Aligned incentive sounds good but costs more long-term.
- •Best for: SaaS businesses that want zero upfront risk and do not mind paying more per recovery.
7. Gravy (custom pricing)
Gravy is different from every other tool on this list. Instead of automated emails, they use actual humans to call and email your failed customers. Think of it as outsourced collections for SaaS.
- •Strengths: Human touch can recover payments that automation misses. High-touch approach for high-value subscriptions.
- •Limitations: Custom pricing (typically $500+/mo). Not self-serve. Overkill for indie SaaS.
- •Best for: Enterprise SaaS with high-value subscriptions where a phone call is worth it.
How to pick the right tool for your SaaS
Under $25K MRR
Focus on flat-fee tools under $50/mo. At this stage, spending $99+/mo on dunning eats into a large portion of what you recover. Revenudge ($19/mo) or ChurnWard ($29/mo) make the most sense financially.
$25K-100K MRR
You can justify more spend. MRRSaver ($49/mo) or Revenudge Growth ($39/mo) give you pre-dunning plus recovery. If you want deep analytics, Churn Buster ($99/mo) becomes reasonable at this scale.
$100K+ MRR
Churn Buster or Gravy. At this scale, even a 1% improvement in recovery rate means thousands of dollars. The cost of the tool is noise compared to the recovery.
Priority: pre-dunning
If preventing failures matters more than recovering them (and it should), look at Revenudge or MRRSaver. Most other tools focus heavily on post-failure recovery and treat pre-dunning as a secondary feature. Learn how pre-dunning works.
Frequently asked questions
What is dunning software?
Dunning software automates the process of recovering failed subscription payments. It detects when a charge fails (expired card, insufficient funds, bank decline), emails the customer to update their payment method, and tracks recovery rates. Some tools also include pre-dunning, which catches expiring cards before the payment fails.
Do I need dunning software if I use Stripe?
Stripe retries failed charges automatically (Smart Retries), but it does not email your customers about expiring cards or send branded recovery emails. If you rely on Stripe alone, you are missing the email side of dunning, which is where most recoveries happen.
How much does dunning software cost?
Prices range from $19/mo (Revenudge) to $249+/mo (Churn Buster) for flat-fee tools. Some tools like FlyCode use performance-based pricing, taking 5-15% of recovered revenue. For indie SaaS founders, flat-fee tools under $50/mo tend to make the most financial sense.
What is the difference between dunning and pre-dunning?
Dunning recovers payments after they fail. Pre-dunning prevents failures by detecting expiring cards and emailing customers before the charge date. Pre-dunning is more effective because the payment never fails in the first place.
