5 Best Dunning Tools Under $50/mo (2026)
Top 3 picks: SaveMRR ($19/mo) for the best all-in-one value with dunning plus 5 more retention engines, Churn Buster ($49/mo) for the deepest dedicated dunning features, and Stripe native dunning (free) if you just need basic retries and nothing else.
I went looking for a dunning tool under $50/mo and found exactly what you'd expect: a lot of "contact sales" pages and not much transparency. So I tested every option that actually publishes a price under $50. I'm the founder of SaveMRR, one of the tools on this list, and I'll be upfront about where it wins and where a dedicated dunning tool does more. Here's the honest breakdown.
The full comparison
| Tool | Price | Dunning emails | Smart retries | Card expiry alerts | Cancel flows | Best for |
|---|---|---|---|---|---|---|
| SaveMRR | $19-49/mo | Yes | Yes | Yes | Yes | All-in-one under $50 |
| Churn Buster | $49+/mo | Yes (advanced) | Yes | Yes | No | Dedicated dunning |
| Slicker | ~$49/mo | Yes | Yes | Limited | No | Payment recovery |
| Stripe native | Free | No | 4 retries max | No | No | Absolute basics |
| ProfitWell Retain | Free* | Yes | Yes | Yes | No | Free tier (sunset risk) |
* ProfitWell Retain was free but is now part of Paddle and being slowly sunset. New signups may be restricted.
1. SaveMRR: best all-in-one under $50
Full disclosure: I built SaveMRR. The dunning engine is one of six retention engines. You also get cancel flows, win-back sequences, pause flows, pre-dunning card expiry alerts, and churn analytics. At $19/mo, it's the cheapest tool on this list that does dunning at all, and the only one under $50 that also handles voluntary churn.
Best for: Indie founders and small teams who want dunning plus everything else in one tool. If you're losing revenue to both failed payments and active cancellations, SaveMRR covers both without stacking two subscriptions.
Not great for: Teams that need the most advanced dunning-specific features. granular email template branching, multivariate subject line testing on dunning sequences, or per-segment retry schedules. Churn Buster goes deeper on pure dunning customization.
2. Churn Buster: best dedicated dunning tool
Churn Buster has been focused on dunning for years and it shows. Their email sequences are deeply customizable. You can branch based on plan type, failed amount, retry count, and customer segment. They also handle in-app card update prompts and have solid analytics on recovery rates per email in the sequence. Their $49/mo entry tier just barely fits the budget here.
Best for: SaaS teams where involuntary churn is the primary problem and you want the most control over your dunning email sequences. If you already handle cancel flows separately, Churn Buster is the strongest single-purpose dunning tool under $50.
Not great for: Founders who also need cancel flows, win-back, or churn analytics. You'd need a second tool for those, which pushes you well over $50/mo total.
3. Slicker: payment recovery focused
Slicker positions itself as a payment recovery platform. It handles dunning emails and smart retries, with a clean interface and quick setup. For more detail, see the SaveMRR vs Slicker comparison. Their card expiry alerting is more limited than Churn Buster's, but the core recovery flow works. Pricing is around $49/mo depending on volume.
Best for: Teams that want a straightforward payment recovery tool without the complexity of Churn Buster's advanced segmentation.
Not great for: Anyone who needs cancel flows or broader churn prevention. Like Churn Buster, it's dunning-only. No voluntary churn coverage.
4. Stripe native dunning: free but bare minimum
Stripe's built-in Smart Retries are on by default. You get up to 4 automatic retry attempts using Stripe's machine learning model to pick optimal timing. That's it. No dunning emails to customers, no card expiry alerts, no in-app update prompts. Your customer's card fails, Stripe silently retries, and if all 4 fail, the subscription dies with no notification.
Best for: Very early-stage products under $2K MRR where the math doesn't justify even $19/mo yet. It's better than nothing.
Not great for: Anyone serious about recovery rates. Without emails, you're leaving the customer completely in the dark about their failing payment. Recovery rates with Stripe-only retries are typically 30-40% lower than tools that add email sequences on top.
5. ProfitWell Retain: free but uncertain future
ProfitWell Retain was the dream: free dunning with smart retries, email sequences, and card expiry alerts. The product still works for existing users. But since Paddle acquired ProfitWell, the focus has shifted to Paddle-native billing. New Stripe-based signups are being restricted, and there's been no meaningful product update to Retain in over a year. I wouldn't start a new integration on a product that's clearly in maintenance mode.
Best for: Teams already using ProfitWell Retain who are happy with the current feature set and willing to accept the risk of eventual sunset.
Not great for: Anyone starting fresh. The migration cost when Paddle eventually forces a transition isn't worth the free price tag today.
Which tool should you choose?
If dunning is your only concern and you want the deepest feature set for it, Churn Buster at $49/mo is the strongest pick. If you want dunning plus cancel flows, win-back, and analytics in one tool for less money, SaveMRR at $19/mo covers more ground. If you're pre-revenue or very early stage, Stripe's native retries are a fine starting point. Just know you're leaving recovered revenue on the table.
My honest recommendation: start with SaveMRR's free Revenue Scan. Use the dunning ROI calculator to estimate your recovery potential, then run the Scan to see exactly how much you're losing to failed payments vs. active cancellations. If failed payments are 80%+ of your churn, a dedicated tool like Churn Buster might make sense. If it's a mix of both, you'll get more value from an all-in-one.
