There is no industry-standard churn definition. Sellers report the number their methodology flatters. The raw Stripe objects tell the full story — now you can verify them yourself, free, before you wire the money.
Free and buyer-run: the seller creates a read-only Stripe key, you get the real numbers — MRR by month, active subs vs claimed, refunds, disputes, the promo cliff, concentration. Or send a CSV for a human-reviewed report.

Want a human-reviewed report on top? Send the seller's CSV — first full report $9, money-back if we miss a red flag.
SaaS sellers optimize metrics for the pitch deck. Logo churn gets massaged. Revenue concentration gets buried. Annual-plan decay gets ignored. You inherit the mess — and you pay for it.
Logo churn or revenue churn. Gross or net. Best cohort month or trailing twelve. Annual plans counted or quietly excluded. Every choice is defensible in isolation — and every choice makes the number smaller.
The result: the churn figure in a data room is a marketing claim computed by the person selling you the business. It is not an audit. It is not a standard. It is a methodology choice you inherit at closing.
→ So we built the tool that computes churn every defensible way, from the raw export.
"The number that matters is never the one in the deck. It's the one you compute yourself, from the raw rows, before the money moves."
One export in. Every churn metric, concentration risk and zombie account out. That's ChurnLens.
Each one is a question sellers hope you never ask. Our report answers all six — directly from the raw data. No guesswork.
The deadliest metric sellers hide. Compares logo churn vs. revenue churn — wide gaps reveal accounts bleeding cash even as headcount holds steady. The wider the gap, the more the headline number is hiding.
Quantifies exactly how much of MRR sits with your top 3 accounts. A single whale leaving shouldn't erase your entire margin of safety.
Annual subscribers are ticking time bombs at renewal. We model who's likely to cancel — and when — so you price that risk into the deal before you close.
Paying customers who haven't logged in for 90+ days. Revenue that looks alive but is already dead. We flag every zombie dollar so you don't pay a multiple on it.
Composite A–F grade weighing retention, concentration, expansion, and growth trends. One letter that tells you whether to walk or wire.
Separates new sales from declining cohorts. Headline MRR can be flat while the underlying base deteriorates. We show you both lines — the story behind the story.
Here's what getting it wrong actually costs. Compared to what ChurnLens costs.
| Cost of Getting It Wrong | Estimated Damage |
|---|---|
| Overpaying by 20–40% on a $500K deal | $100,000 – $200,000 |
| Lost ARR from undetected churn (year 1) | $45,000 – $95,000 |
| Whale customer departure within 6 months | $60,000 – $150,000 |
| Opportunity cost — capital tied up in a lemon | Priceless |
| ChurnLens full risk report: $9 one-time, no subscription | |
$9 to avoid a $100K+ mistake. That's the math.
For due diligence, the seller creates a restricted Stripe key that can only view data — Subscriptions, Charges, Refunds, Disputes, Events. It cannot change or delete anything, and they can delete it the moment you're done. Copy-paste instructions to send them.
The verifier reads the raw subscription objects Stripe bills on — read-only, in memory, nothing stored — and computes the buyer-side metrics itself. See exactly how each number is computed.
MRR by month, active subs vs claimed, refunds and disputes, the promo cliff, customer concentration, failed payments — with red flags in plain English and a timestamped, SHA-256-stamped report you can bring to the negotiation. Run the demo first — synthetic data, no key needed.
Less reliable alternative: a seller-supplied CSV report ($9 first report) — a file the seller prepared and can shape. Use it when Stripe isn't the billing system.
