The 12-Point SaaS Acquisition Checklist That Buyers Actually Use
You've built something real. Your SaaS has customers, recurring revenue, and a team. Now an acquirer is interested—and suddenly you're staring at a 60-page due diligence list from their legal team.
Most founders see this moment as a binary: pass or fail. But that's wrong. Due diligence isn't a test you either ace or flunk. It's a conversation where gaps in your financial data, customer contracts, or metrics kill deals that should have closed.
A SaaS acquisition checklist isn't something you build after an offer lands on your desk. It's something you build months before—so when buyers dig, they find proof instead of promises. This post walks through the 12 things that most commonly derail SaaS acquisitions at due diligence, and how to prepare for each one.
What Metrics Do SaaS Buyers Always Demand First?
The moment a buyer's financial team gets involved, three numbers matter above everything else: MRR, churn, and NRR. Everything else flows from these three.
MRR and Its Growth Rate
Monthly Recurring Revenue shows the predictable, recurring income your business generates. Buyers don't care about annual contracts or one-time deals in the same way—they care about what you can count on next month.
Have a clear breakdown: What is your current MRR? What was it 12 months ago? What's the month-over-month growth rate? Buyers are looking for consistency. A business with $50k MRR growing 3% month-over-month is more attractive than one that jumped from $30k to $70k in two months (which signals an unsustainable spike, not a trend).
If you've been manually tracking MRR in a spreadsheet, stop. Buyers will ask for source-connected proof. They want to see the revenue directly from Stripe, or your billing system's API, not a screenshot you updated last Thursday.
Gross and Net Churn
Churn is the percentage of customers you lose each month. Gross churn is how many you lose. Net churn accounts for expansion revenue—customers who upgrade and buy more from you.
For early-stage SaaS, 5-7% monthly churn is acceptable. 3-5% is good. Above 10%, and buyers start modeling how long the business will survive. Net negative churn (expansion revenue outpaces losses) is the holy grail—it means your business grows even if you acquire zero new customers.
This metric is complex to calculate manually. Buyers know it. If you hand them a spreadsheet, they will ask your founder or CFO to walk through the math on a call. If the logic breaks down, deal momentum stops.
CAC Payback and LTV:CAC Ratio
Customer Acquisition Cost is how much you spend to acquire a customer. CAC payback period is how long it takes for that customer's gross margin to cover that cost. Buyers look for payback under 12 months; under 6 months is strong.
LTV (Lifetime Value) divided by CAC should be at least 3:1. This shows your unit economics are sustainable. If you're spending $500 to acquire a customer and their LTV is $800, that's a problem for a buyer's financial model.
You need clean numbers here. Attributing customer acquisition spend to channels, calculating average customer lifetime by cohort, normalizing for free trials—this requires either a finance hire or a tool that connects your billing system, marketing platform, and analytics tool. Buyers will verify every number.
Which Financial Documents Trigger the Biggest Red Flags?
Beyond metrics, buyers scrutinize your actual financial infrastructure. Here are the documents that make or break deals:
Tax Returns vs. Accounting Records
Your last two years of tax returns must match your bookkeeper's records, which must match your banking data. If an acquirer's accountant finds a $15k discrepancy between your 1099 and QuickBooks, they will pause the deal and request a full audit. This costs time and money.
Spend 30 minutes right now and reconcile. Pull your tax returns. Pull your P&L from your accounting software. Pull your bank statements. Do the numbers align? If not, fix it before a buyer finds it.
Customer Contracts and SLAs
Buyers want to see a sample of your customer contracts. They're looking for: lock-in terms, refund clauses, price-increase language, and service level agreements you've committed to.
If you have 200 customers with 200 slightly different contracts, that's a red flag. It suggests operational chaos. Standardize your contract now. If you promised a customer 99.95% uptime but have no monitoring system to prove you hit it, a buyer will net that into their valuation as legal risk.
Expense Breakdown and Cost of Goods Sold
A buyer needs to understand what it actually costs you to run this business. COGS includes cloud hosting, payment processing fees, third-party APIs, and support labor. Fixed operating costs include salaries, office, tooling.
If your gross margin is unclear—or worse, if it shrinks as you scale—buyers will model conservatively and lower their offer. Get this clean before they ask.
What Customer Data Makes Buyers Nervous?
Your customers are the asset. Buyers will dig into customer quality, concentration, and risk.
Customer Concentration
If one customer represents more than 10% of your MRR, a buyer will ask: What's the contract length? When does it renew? Can they leave with 30 days' notice? If your top 3 customers are 40% of revenue and any of them could churn tomorrow, the buyer will discount the acquisition price significantly.
Diversify before you sell, or be transparent about contract terms. A buyer would rather pay less for predictable revenue than overpay for revenue that could evaporate.
Churn by Cohort
Show customers segmented by when they signed up. A cohort from January 2023 that still has 80% of its original customers is healthy. If the same cohort is down to 40%, there's a quality or product-market fit problem. Buyers can see this in the data—don't hope they miss it.
NPS and Customer Satisfaction Data
Net Promoter Score doesn't make or break a deal, but it does shape buyer confidence. If your NPS is above 40, that's strong validation. If it's below 30, a buyer will worry about churn post-acquisition. Have recent, real NPS data from surveys sent to actual customers—not a guess.
Are Your Operational and Legal Details Actually Documented?
Buyers care about metrics and financials, but they also care about whether your business will function during and after acquisition. Gaps here slow deals down.
Intellectual Property and Technology Stack
Do you own the code? All of it? If you outsourced development to a contractor, did they sign an IP assignment agreement transferring ownership to you? Buyers will search for this. If you don't have it, deal closes get delayed while lawyers negotiate retroactive IP transfers—which are expensive and slow.
Document every third-party tool, API, and library you use. If your product relies on an API from a competitor or a single open-source library, disclose it. Buyers will research this anyway.
Employment and Contractor Agreements
Every team member needs an employment agreement. Every contractor needs a statement of work. Every advisor needs a cap table entry. Buyers want to know: Who owns what percentage? What equity vests? Are there any handshake deals or verbal agreements that could complicate the cap table post-acquisition?
Messy equity kills deals. Clean cap table with all vesting schedules documented moves deals forward.
Insurance and Compliance
Do you have general liability insurance? Cyber insurance? If you handle customer data, are you GDPR and CCPA compliant? Are you SOC 2 certified or working toward it? Buyers will ask. If you don't have answers, they will reduce the purchase price to account for future compliance costs.
How Do You Prove All This to a Buyer Without Screenshots?
Here's the core problem: Buyers ask for metrics. You send screenshots. Screenshots prove nothing. A buyer could screenshot anything, modify it in Figma, and send it to their team. It's not verifiable.
This is where verified metrics pages change the game. Instead of screenshots, you create a live, source-connected metrics page that pulls data directly from your billing system, analytics tool, and monitoring platform. Stripe revenue syncs live. Churn calculates in real time. Every number is cryptographically verified.
A buyer sees your page, clicks through to see the live data, and trusts it immediately. No follow-up emails asking for spreadsheets. No doubt about whether the numbers are real. You can start this process months before you talk to an acquirer—to prove to investors, partners, or potential customers that your business is solid. Then, when a buyer shows up, the verified proof is already there.
