Is my billing data safe?

Yes. We only read data — we cannot modify your billing, create charges, or access card numbers. All supported platforms (Stripe, Polar, Paddle) support restricted read-only keys. Your key is used only during the scan and is never stored or logged.

Which billing platforms do you support?

We support Stripe, Polar.sh, and Paddle. Select your platform on the scan page and we'll guide you through creating an API key. Each platform gets a tailored scan covering the leak types it supports.

What permissions does the API key need?

Read access for: Customers, Subscriptions, Invoices, Products, Prices, Coupons, and Payment Methods (exact names vary by platform). We provide step-by-step instructions on the scan page. It takes about 60 seconds to create.

How long does the scan take?

Under 90 seconds for most accounts. Larger accounts (1,000+ customers) may take up to 3 minutes. You'll see real-time progress as we scan each category.

What exactly do you scan for?

We run 10 automated checks: (1) Expired coupons still discounting, (2) Legacy pricing below current rates, (3) Forever discounts with no end date, (4) Stuck subscriptions stuck in bad states, (5) Expiring cards within 90 days, (6) Uncollected revenue with open invoices, (7) Missing payment methods on active subscriptions, (8) Unbilled overages — quantity mismatches and usage exceeding plan limits, (9) Expired trials — subscriptions stuck in trialing status, (10) Duplicate subscriptions — customers charged twice after failed upgrades.

What do I do with the report?

Open the report. See the leak. See the dollar amount. See the one-sentence fix. Click the link — it takes you straight to that customer in your billing dashboard. Fix it. That money hits your account next billing cycle.

What if you don't find any leaks?

Then your billing is clean. You get a perfect health score and some peace of mind. The free scan costs you nothing either way. If you're on a paid plan and we find less than $1,000/mo, you pay nothing.

What happens when a Stripe coupon expires?

When a Stripe coupon's redeem_by date passes, the coupon stops accepting new redemptions — but existing subscriptions keep the discount indefinitely. Stripe does not auto-remove expired coupons from active subscriptions. RevReclaim scans for these zombie discounts and shows you exactly which subscriptions are affected and how much they're costing you.

Is this the same as chargeback recovery?

No. Chargeback tools handle disputed payments. We find revenue you earned but aren't collecting: expired discounts still running, subscriptions stuck in failed states, cards about to expire, and outdated pricing that was never updated. Different problem, different fix.

Can I cancel the monthly plan anytime?

Yes. No contracts, no lock-in. Cancel anytime from your dashboard. Your data is deleted within 30 days of cancellation.

Is this worth it if I have fewer than 50 customers?

Probably not. Revenue leaks compound with scale. If you have 10 customers, you probably know each one by name. RevReclaim is built for the stage where your billing account has grown past what one person can monitor — typically 100+ customers, $30K+ MRR.

Why should I trust you with my billing data?

Fair question. We designed RevReclaim to work with restricted, read-only API keys scoped to specific resources. We only perform read operations, never modify your data, never see card numbers, and never store the key after the scan.

7 Best Revenue Leakage Detection Tools for SaaS (2026)

Your Stripe account is probably leaking money. The question is: which tool should you use to find and fix it?

We looked at 7 tools that tackle revenue leakage for SaaS companies. Some focus on dunning (recovering failed payments). Some do analytics. One scans for all leak types at once. Here's the breakdown.

What to Look For in a Revenue Leakage Tool

Before the list, here's what actually matters:

Detection scope: Does it only catch failed payments, or does it scan for other leak types too? (coupons, ghost subscriptions, legacy pricing, expired trials...)
Platform support: Stripe only? Or also Paddle, Polar, and others?
Time to value: Can you get results in minutes, or does it take weeks to set up?
Recovery vs. detection: Some tools find the problem. Some fix it. The best ones do both.
Price: Is it worth it relative to what you're losing?

The 7 Tools

1. RevReclaim

What it does: Scans your billing account for 10 types of revenue leakage. Failed payments, expired cards, ghost subscriptions, never-expiring discounts, legacy pricing, duplicate subscriptions, missing payment methods, expired trials, unbilled overages, and expired coupons. Returns a full report in under 60 seconds.

Platforms: Stripe, Paddle, Polar

Best for: SaaS founders who want a complete billing health check, not just dunning.

Price: Free scan. Paid plans for ongoing monitoring and automated recovery.

What makes it different: Most tools on this list focus on one type of leak (usually failed payments). RevReclaim scans for all 10. Think of it as a billing audit on autopilot.

Honest take: If your only problem is failed payments, a dedicated dunning tool might be a better fit. But if you've never audited your billing, the free scan is worth running just to see what's there. Most accounts have 3-4 leak types they didn't know about.

2. Churn Buster

What it does: Dunning management. When a payment fails, Churn Buster handles the retry logic and customer communication. Emails, SMS, in-app messages. They've been doing this since 2013, so their playbooks are battle-tested.

Platforms: Stripe, Braintree, Chargebee

Best for: SaaS companies with high involuntary churn who need a proven dunning system.

Price: Starts around $100/mo. Scales with MRR.

What makes it different: 10+ years of data on what recovery sequences actually work across different industries. Their retry timing is based on patterns from hundreds of SaaS businesses.

Honest take: If failed payments are your main problem, Churn Buster is probably the best pure dunning tool out there. But it only does dunning. It won't tell you about your zombie discounts or legacy pricing issues.

3. Baremetrics Recover

What it does: Part of the Baremetrics analytics suite. Recover adds failed payment recovery on top of their subscription analytics. Automated emails, payment form links, retry attempts.

Platforms: Stripe, Braintree, App Store, Play Store, Chargebee

Best for: Teams that already use (or want) Baremetrics for analytics and want recovery built in.

Price: Analytics starts at $108/mo. Recover is an add-on.

Honest take: The analytics are the real product here. Recover is solid but basic compared to dedicated dunning tools. If you want one dashboard for metrics AND recovery, this works. If you just want recovery, it's expensive for what you get.

4. ChurnKey

What it does: Two things: cancel flow optimization (reducing voluntary churn) and payment recovery (reducing involuntary churn). The cancel flow shows targeted offers when someone tries to cancel. The recovery side handles dunning.

Platforms: Stripe, Chargebee, Braintree, Paddle

Best for: SaaS companies that want to reduce both voluntary AND involuntary churn in one tool. Read more about churn vs revenue leakage to understand the difference.

Price: Starts at $50/mo + performance fee on recovered revenue.

What makes it different: The cancel flow feature is genuinely useful. Most other tools on this list don't touch voluntary churn at all.

Honest take: Good if you have both a cancellation problem AND a failed payment problem. If it's only failed payments, the performance fee model can get expensive.

5. Stripe Revenue Recovery (Built-in)

What it does: Stripe's native features: Smart Retries (ML-based retry timing), automatic card updaters (syncs with card networks when cards are reissued), and basic dunning emails.

Platforms: Stripe only (obviously).

Best for: Early-stage SaaS that wants basic recovery without paying for another tool.

Price: Free (included with Stripe Billing).

What makes it different: It's already in your stack. No integration needed. Zero setup friction.

Honest take: Recovers about 38% of failed payments. That's decent for free, but it leaves 62% on the table. The dunning emails are generic and the retry logic treats all decline types the same way. Most SaaS companies outgrow Stripe's built-in recovery fairly quickly.

6. Stunning.co

What it does: Dunning management specifically for Stripe and Subbly. Failed payment emails, in-app notifications, and customer self-serve payment update pages.

Platforms: Stripe, Subbly

Best for: Small SaaS companies on Stripe that want simple, affordable dunning.

Price: Free tier available. Paid starts at $50/mo.

What makes it different: Simple setup. Clean email templates. Doesn't try to do too much.

Honest take: Solid starter tool. Does one thing and does it well. But if you outgrow basic dunning or switch off Stripe, you'll need to migrate.

7. Chargebee Revenue Recovery

What it does: Part of the Chargebee billing platform. Includes Smart Retry (ML-based), dunning sequences, and automated workflows for failed payments. Also handles revenue recognition and billing automation.

Platforms: Multi-gateway (Stripe, Braintree, Adyen, etc.)

Best for: Mid-market SaaS that needs a full billing platform with recovery built in.

Price: Starts at $249/mo. Revenue Recovery included in higher tiers.

What makes it different: It's a complete billing platform, not just a recovery tool. If you're outgrowing Stripe Billing, Chargebee handles the whole stack.

Honest take: Overkill if you just want leakage detection. This is a billing platform decision, not a recovery tool decision. If you're already on Chargebee, use their recovery features. If you're on Stripe and happy, don't switch billing platforms just for dunning. See our Stripe vs Paddle vs Polar comparison for more.

So Which One Should You Pick?

"I've never audited my billing and don't know what I'm losing." Start with RevReclaim's free scan. See what's actually wrong before buying a tool. You might only need dunning. You might have 5 other issues.

"I know failed payments are my problem and I want to fix it now." Churn Buster if you want the best recovery rates. Stunning.co if you want simple and affordable.

"I want analytics AND recovery in one place." Baremetrics if you're analytics-focused. ChurnKey if you also want cancel flow optimization.

"I'm early stage and want to spend $0." Start with Stripe's built-in Smart Retries and card updater. Enable them in your Stripe dashboard (they might not be on by default). Then upgrade when you hit $10K MRR and the 62% miss rate starts hurting.

"I'm considering switching billing platforms entirely." Look at Chargebee. But that's a billing decision, not a leakage decision. Don't confuse the two.
