Most brokers will try to sell you a SaaS the same way they sell an ecom store: they point at a big revenue number and say, “See? It’s healthy.”
And sure, a chart showing $20,000 MRR with a nice up-and-to-the-right curve looks comforting.
But here’s the technical truth, friend: top-line revenue is a mirage if churn is high. A leaky bucket SaaS can look “amazing” on paper while quietly dying underneath. If the seller is spending $15,000/month on ads just to replace users who cancel after 30 days, you’re not buying a stable business. You’re buying a treadmill.
So let’s strip away the vanity metrics and get you to the only thing that matters: how long users actually stay subscribed. This is how you verify true customer retention, see the real MRR churn rates in detail, and avoid fake MRR claims.
The Hook: The “Mirage MRR” Fear
Key takeaway: MRR can look strong while retention collapses. If users churn fast, the “business” is just paid acquisition keeping the lights on.
Here’s the scenario.
You’re evaluating a micro-SaaS doing a steady $20K MRR. The seller sends a basic P&L and a screenshot of Stripe with that beautiful curve. They’re confident. Maybe even a little pushy.
But your gut says, “What if this is pumped up?”
That fear is rational. Sellers can “inflate” MRR in two common ways:
- They run heavy promos (discounted annual plans, lifetime deals) right before selling.
- They burn cash on ads to keep the top-line number alive while users churn like crazy.
The result is the same: the dashboard looks great, but retention is falling apart. You take over, the promo users charge back or disappear, and suddenly you’re holding a dying business with high churn.
The promise of this guide is simple: you’ll learn the audit framework that exposes the leaky bucket before you make an offer.
The “Easy” Assets (What Transfers Instantly)
Verdict: Code and billing access can transfer cleanly while the real risks hide in IP, tax liabilities, and retention decay.
A lot of the handover stuff really is easy:
- Code & IP: GitHub repo, domain ownership, maybe a few design files.
- Payment gateway: Stripe or Paddle admin access.
- App architecture: the UI, database, hosting, the whole stack.
But don’t let “easy transfer” trick you into thinking it’s “safe.”
Code can transfer cleanly while the legal rights are a mess. It happens more than people admit — IP theft, copied designs, unreported VAT/GST liabilities, the works. If you want to protect yourself from the boring-but-deadly stuff, read this before you sign anything:

But assuming you are buying this SaaS, the real question is next.
The Hard Asset: Detailed Cohort Analysis (The part sellers avoid)
Key takeaway: You can’t evaluate a subscription business with one MRR screenshot. Cohorts reveal the truth.
Here’s the cold truth: you can’t evaluate a subscription business by staring at one month of revenue.
Sellers love sharing MRR screenshots. They hate sharing a proper SaaS metrics MRR breakdown because it exposes churn.
And churn is everything.
This is the leaky bucket trap: if your LTV (lifetime value) is $50 but your CAC (cost of acquiring a customer) is $45, the business model is basically broken. You’re buying a machine that eats money.
The “Pump & Dump” Risk: Why Stripe Screenshots Lie
Verdict: Promotions can spike Stripe without creating durable revenue. Retention tells you what’s real.
Here’s how fake MRR claims happen without technically “lying.”
A seller runs a massive promotion 60 days before listing: “90% off annual” or a “lifetime deal.” Stripe spikes. The valuation conversation gets exciting.
Then you take over.
Thirty days later, reality shows up: users who bought on impulse realize the product is buggy, support is slow, or onboarding is weak. They cancel, dispute charges, or chargeback. Your revenue drops, and you’re stuck cleaning it up.
So your rule is simple:
Never accept static screenshots.
Demand read-only access to the actual processor (Stripe/Paddle/Braintree) or to an analytics overlay like Baremetrics/ProfitWell. If they refuse, that refusal is the data.
The Protocol: How to Audit True Retention (the three checks)
Key takeaway: Three checks expose the leaky bucket: cohorts (Month 3), net MRR math, and LTV:CAC.
This is the framework I’d want you to use every time.
Step 1: Isolate cohorts
Group users by the month they signed up. Then look at Month 3 retention.
Month 1 can look fine because people are “testing.” Month 2 might still be okay. Month 3 is where the truth lives.
If 60% of users who signed up in January are gone by March, the product has a fatal flaw. That’s not “normal churn.” That’s “people don’t stick.”
Step 2: Separate gross MRR from net MRR
You need the SaaS metrics MRR breakdown: new revenue minus churned revenue minus downgrades.
If Net MRR is negative unless they keep injecting ad spend, walk away. That’s a leaky bucket with a fresh coat of paint.
Step 3: Run the LTV:CAC test
A healthy SaaS usually needs at least a 3:1 LTV:CAC ratio.
If it costs $100 to acquire a customer, that customer should generate $300+ in gross profit over time. If the ratio is 1:1, you’re not buying a business. You’re buying a job managing churn.
Don’t Buy a Revolving Door
Key takeaway: If growth requires constant paid acquisition to replace churn, it isn’t stability — it’s a treadmill.
Stable revenue is an illusion if it requires constant expensive marketing just to replace lost users.
So don’t get hypnotized by top-line graphs. Demand cohort data. Verify true customer retention. Check MRR churn rates in detail. Calculate CAC vs. LTV.
Because a SaaS with high churn isn’t “high-growth.” It’s a revolving door.
And that’s exactly why, at Ecom Chief, we look under the hood of retention before listing software — so buyers aren’t walking into a leaky bucket.
Final Word
Verdict: Don’t buy “MRR.” Buy retention.

Video recommendation
Key takeaway: Watch this, then re-check the seller’s Month 3 retention. The red flags become obvious.
This video is a great companion to this post because it explains how VCs actually calculate retention using cohort analysis — exactly the kind of “show me the real numbers” mindset you need before buying. Watch it once, then re-check the seller’s data with Month 3 retention in mind. It’ll make the red flags obvious.
