Comparison · Dunning Software · 2026
If you run a subscription product in 2026, dunning is no longer nice to have — it's table stakes for protecting revenue you've already earned. Between card expiries, soft declines, SCA challenges, and app-store quirks, it's common to lose 1–4% of MRR every month to failed payments alone. This guide compares seven dunning tools across real-world criteria: payment processor coverage, RevenueCat and app-store support, messaging flexibility, and integration fit. It's intentionally fair — there are cases where a Stripe-only tool or all-in-one billing platform will beat Recurflux, and we call those out.

Evaluation
Evaluation
When you evaluate dunning tools, you're solving for both coverage and control. Coverage is about how many failure scenarios the tool actually sees: card charges, alternative payment methods, in-app purchases, app-store subscriptions, and manual invoices. Control is how precisely you can orchestrate retries, emails, in-app prompts, SMS, and product access so that you recover payments without annoying good customers.

Recurflux is a dedicated churn and recovery platform built for SaaS teams that have outgrown Stripe-only setups and now juggle multiple processors or app-store revenue via RevenueCat. Instead of bolting dunning onto a billing product, it treats failed payment recovery as the primary job — with native support for both traditional payment processors and RevenueCat events.
What it does
Recurflux plugs into your payment processors (Stripe, Paddle, Razorpay, Cashfree, or others) and RevenueCat to collect all failed payment signals into a single recovery engine. It then runs multi-channel playbooks: smart retries tuned per decline code and processor, branded email sequences, in-app prompts, and flows that let customers update payment details without friction. For RevenueCat apps, it connects directly to subscription and billing events so you can recover renewals that fail inside the app stores — which most generic dunning tools cannot see.
Pros
Cons
Best for: SaaS companies using multiple processors who want one recovery system. Mobile apps on RevenueCat that need proper dunning around in-app subscriptions. Teams that already have billing covered but lack a specialized recovery layer.
Pricing
From $59/mo (Rise) · $159/mo (Surge) for Stripe, Paddle, Razorpay, Cashfree. From $29/mo for RevenueCat plans. Flat fee — no percentage of recovered revenue.

Churnkey started as a cancel-flow optimization product and evolved into a broader churn platform covering both voluntary and involuntary churn. It's optimized for web-based SaaS that wants to reduce cancellations at the moment of churn while also running dunning for failed payments.
What it does
Churnkey plugs into Stripe (and some other billing systems) to power smart cancel pages, save offers, and feedback surveys that reduce voluntary churn. On the recovery side, it provides email and retry workflows for failed payments so you can tackle involuntary churn without switching tools.
Pros
Cons
Pricing
MRR-based and/or per-customer tiers, typically starting around $250–$700/mo depending on scale.

Churn Buster is one of the earliest dedicated dunning products in the Stripe ecosystem, with a long track record of helping SaaS companies reduce involuntary churn through email sequences and smart retries. Built for teams that want a mature, battle-tested recovery system tightly integrated with Stripe.
What it does
Churn Buster takes failed payment events from Stripe, then runs a structured series of emails, in-app messaging, and retries designed to recover payments without damaging customer relationships. It focuses on detailed, time-tested campaigns rather than trying to be a full billing or analytics suite.
Pros
Cons
Pricing
From ~$149/mo, scaling with MRR or customers monitored.

Stripe Billing includes basic dunning features and Smart Retries, which intelligently re-attempt card charges based on past data across the Stripe network. For early-stage Stripe-only SaaS, this built-in option can be enough to recover a meaningful chunk of failed payments with zero extra tools.
What it does
Smart Retries uses ML models to decide when to retry failed charges, increasing the chance of eventual success. You get simple email notifications for expired cards and payment method updates, all managed from Stripe's dashboard. Recovers 30–40% of failed payments — the floor, not the ceiling.
Pros
Cons
Pricing
Included with Stripe Billing. No additional cost beyond normal Stripe processing fees.

How to Choose
How to Choose
1. Using RevenueCat or app-store subscriptions for meaningful revenue?
Yes → Recurflux. Native RevenueCat integration — most tools never see app-store failures at all.
2. Want to migrate your billing platform entirely?
Yes → Evaluate Chargebee Smart Dunning as part of a full billing migration.
3. Running multiple payment processors or complex setups?
Yes → Recurflux. Built for multi-processor coverage from day one.
4. Is voluntary churn (deliberate cancellations) your biggest problem?
Yes → Churnkey. Best-in-class cancel flow tooling — stronger than Recurflux's cancel flow feature for pure cancellation deflection.
5. Already using Baremetrics and want analytics + dunning bundled?
Yes → Baremetrics Recover. Keeps everything in one tool.
6. Pre-$10K MRR, Stripe-only, tight budget?
Start with Stripe Smart Retries or MRRSaver. Add Recurflux when you cross $10–20K MRR and start feeling the gap.
7. Past $10K MRR, Stripe-only, and want specialized involuntary churn coverage?
Recurflux (multi-processor + RevenueCat flexibility) or Churn Buster (Stripe-only depth). Recurflux wins on roadmap; Churn Buster wins on years of Stripe-specific tuning.
FAQs
FAQs
What is dunning in SaaS?
Dunning is the process of communicating with customers to resolve failed or overdue subscription payments, usually via emails, in-app prompts, and automated retries. A well-run dunning system recovers 50–75% of failed payments; default processor behavior recovers 30–40%.
Can I just use Stripe's built-in dunning instead of a separate tool?
Yes — Stripe Smart Retries and its email notifications are enough for many early-stage SaaS products. But you miss advanced segmentation, multi-processor coverage, RevenueCat support, code-specific retry logic, and the detailed analytics available in dedicated tools.
Which dunning tool works with RevenueCat?
Most generic dunning tools only integrate with Stripe or other card processors and never see app-store failures. Recurflux is built to work natively with RevenueCat, so it can run recovery campaigns for mobile subscriptions alongside traditional card billing.
Do I need full billing software like Chargebee to get good dunning?
No. Many teams layer a specialized dunning tool on top of Stripe or another processor so they keep their billing setup and add a recovery layer without a migration. Chargebee makes sense when you need full billing, invoicing, and dunning from one platform.
How much revenue can dunning software recover?
It's common for SaaS businesses to see 1–4% of MRR at risk each month from failed payments. A well-configured dunning system with code-specific retry logic recovers 50–75% of those failures. Default Stripe Smart Retries alone recover 30–40%.
What is the difference between involuntary and voluntary churn?
Involuntary churn happens when a customer's subscription lapses because of a failed payment — not because they chose to leave. Voluntary churn is a deliberate cancellation. Dunning tools (like Recurflux, Churn Buster, and Stripe Smart Retries) address involuntary churn. Cancel-flow tools (like Churnkey) focus on voluntary churn.
What is the best dunning software for Razorpay?
Recurflux is the only dedicated dunning tool with native Razorpay support. It maps 30+ Razorpay failure codes to code-specific retry schedules and dunning sequences. Generic dunning tools like Churn Buster and MRRSaver are Stripe-only and will not see Razorpay payment failures at all.
How much does dunning software cost?
Dunning software ranges from $0 (Stripe's built-in Smart Retries) to $700+/month for enterprise-focused tools. Recurflux charges $59/month (Rise plan) or $159/month (Surge plan) as a flat fee with no percentage of recovered revenue. Churn Buster starts around $149/month. Churnkey starts around $250/month. Chargebee bundles dunning into its broader billing platform pricing.
Does dunning software work with RevenueCat?
Most dunning tools do not support RevenueCat because they are built for card-payment processors, not App Store or Google Play billing. Recurflux has native RevenueCat integration and can run dunning campaigns triggered by RevenueCat subscription and renewal events, including grace period failures and lapsed subscriptions. This makes it the only purpose-built dunning tool for mobile apps using RevenueCat.
What recovery rate should I expect from dunning software?
With no dunning (manual-only), 10–20% of failed payments are recovered. Stripe Smart Retries alone recovers 30–40%. A basic 3-step dunning email sequence recovers 40–50%. Code-specific retry logic combined with a 5-step dunning sequence significantly outperforms generic ML retry. A full 5-layer recovery stack maximises recoverable payments. The gap between default behavior and an optimized dunning stack at $100K MRR can be substantial.
