🕵️ Due Diligence Case Study: $72,000 Lost After Buying a SaaS the Buyer Couldn’t Operate
(How a lack of technical aptitude destroyed a profitable asset in under 90 days)
Asset Profile: The “Simple” SaaS That Wasn’t Simple
| Key Metric | Seller Claim |
|---|---|
| Niche | B2B Productivity Tools |
| Monetization | Monthly SaaS Subscriptions |
| Asking Price | $120,000 |
| Claimed Monthly MRR | $3,000 |
| Implied Multiple | 40x |
The seller positioned the SaaS as “low maintenance,” “no-code,” and “fully automated.” The reality was very different.
🔍 Discovery Phase: The Hidden Technical Risk
The buyer —with no technical background— relied on:
- Dashboard screenshots
- A walkthrough video
- A 45‑minute handover call
Using the Technical Viability Checklists from our kit, the buyer requested:
- Read‑only access to the code repository (GitHub)
- Error logs from the last 12 months
- Internal documentation
- A full list of external dependencies (APIs, cron jobs, workers)
This revealed the real problem.
🛑 Critical Red Flag: Total Founder Dependency
The SaaS had an architecture only the founder understood.
| Area | Seller Claim | Due Diligence Finding |
|---|---|---|
| Codebase | “No‑code + simple scripts” | 14,000 lines of custom code |
| Infrastructure | “Automatic” | 7 cron jobs + 3 manual workers |
| Integrations | “Plug & play” | 4 undocumented APIs |
| Maintenance | “1 hour/month” | 8–12 hours/month required |
The SaaS worked… as long as the founder was behind it.
📉 Operational Viability Impact
The key question from the kit: Can the new owner operate the asset without the seller? The answer was NO.
Operational SDE Adjustment
| Concept | Seller Claim | DD Adjustment | Actual Operational SDE |
|---|---|---|---|
| Monthly MRR | $3,000 | $0 | $3,000 |
| Churn | 3% | +7% | 10% real |
| Monthly Dev Cost | $0 | -$800 | -$800 |
| Maintenance Time | 1h | +11h | 12h real |
| Monthly SDE | $2,900 | N/A | $1,700 |
This was not a passive asset. It was a hidden technical job.
đź’Ą Outcome: Shutdown in 90 Days
After the acquisition:
- A critical API failed
- The buyer couldn’t restart the workers
- Customers received repeated errors
- Churn spiked to 25%
- MRR dropped below $1,000
- The SaaS became non‑viable
The buyer shut it down within 3 months.
Total Loss:
$120,000 purchase + $2,400 in emergency dev costs = $122,400 USD
🔑 Lessons for Investors
1) Aptitude Before Price If you can’t operate the asset, it’s not an investment. It’s a liability.
2) Technical Viability Is Part of SDE A SaaS with undocumented dependencies is worth less, even if revenue looks strong.
3) Founder Dependency Is a Financial Risk If the business only works with the founder, it’s not a business. It’s a disguised job.
4) Due Diligence Is Survival The mistake wasn’t financial. It was operational.
