If you’re a SaaS founder preparing for an acquisition or exit, you’ve probably spent time growing your recurring revenue, acquiring customers, and creating value.

That's why you should perform a rigorous analysis of your business sale to streamline the due diligence, improve buyer confidence, and influence your deal value.

This guide breaks the SaaS M&A due diligence checklist into actionable categories, highlighting where issues often arise and how to build an organized virtual data room.

6 SaaS M&A Due Diligence Workstreams

Each of the SaaS M&A due diligence workstreams gives buyers the confidence, reduces M&A delay, and helps everyone move forward to make an informed decision.

Strong preparation centers on these 6 core areas:

  1. Financial and KPI Readiness: Your company’s statements and KPIs must be consistent, GAAP-aligned, and tied to a single source of truth.
  2. Technical: Quantify your technical assets, including the codebase, infrastructure, and compliance. It’s important to assess the longevity of the core platform and its capability to adapt to future changes.
  3. Legal and IP: The buyer requires confidence that the technology ownership and IP documentation are clean and defensible. You should verify your software licenses and source code to minimize legal and security risks.
  4. Commercial: Evaluate your business growth targets and validate the quality of your revenue. Focus on your customer relationships and how they support your future forecasts.
  5. Human Resources (HR) and Team: Your business should have strategically aligned personnel that can help the company thrive after an acquisition. However, there shouldn’t be a dependency on the key person.
  6. Operational: Your company should show that it’s resilient to post-acquisition risks. So, you should outline your customer concentration and key documentation.

We will explore the main ones in detail below.

However, each of these categories can be intense and determine the outcome of your deal. That’s why you should never leave anything to chance.

In our experience, business owners who prepare early can reduce surprises during the M&A process. At Exitwise, we’re a founder-led M&A advisory firm that guides founders in preparing to exit their businesses at the best price and terms. We offer exit readiness services to prepare your SaaS company by identifying risks and appealing to your buyers.

Financial Due Diligence for SaaS Companies

You should showcase strong operations and finances during the due diligence phase. Here are the two areas you should consider:

SaaS Metrics

The metrics help buyers to take a closer look at growth, efficiency, and the durability of your SaaS business:

  • Monthly and Annual Recurring Revenue (ARR and MRR): Clean MRR/ARR that reconciles with the bank statements shows steady month-over-month growth and no unexplained spikes.
  • Customer Acquisition Costs (CAC): A healthy SaaS business should have a lifetime value to acquisition (LTV: CAC) ratio of 3:1 or higher
  • Payback Periods: If your business has a CAC payback period under 12 months, it demonstrates it’s efficient and scalable.
  • Gross Margins: If your business has a margin above 75%, it’s likely to attract premium SaaS valuations.
  • Net Revenue Retention (NRR): Your NRR signals how well the business grows within the existing customer base. In the rule of 40, your NRR and EBITDA margin should equal or exceed 40 percent.

Financial Statements

Buyers use these files for financial analysis to assess your company’s performance and identify potential risks.

You should have:

  • Audited 3 to 5 years of financial statements, including forecasts, budgets, tax filings, and management accounts.
  • Reconciled EBITDA adjustments and revenues to show your actual business performance.

Technical Due Diligence for SaaS Companies

Investors assess whether your company’s technical roadmap aligns with their objectives and the market expectations.

Your SaaS business, therefore, should demonstrate clear alignment in the areas below:

Code Security and Documentation

You should scrutinize your cybersecurity practices and any historical incidents. Gather your company’s audit history to showcase its approach to security and data protection.

You should also include security detention plans and processes to address threats, vulnerabilities, and security gaps.

Code Quality and Documentation

Your software architecture should be scalable at a reasonable cost.

Create documentation that explains your software's development processes and your team’s capabilities for actively maintaining it.

Infrastructure and Scalability

Validate the technical feasibility of your SaaS company, showing that it can deliver on its promises and scale with growing demand.

You should uncover any technical debt or infrastructure limitations that may need future investment.

Legal and IP Due Diligence for SaaS Companies

Your software license and IP agreements should be legally sound, with no hidden liabilities, to avoid costly disputes and enable seamless post-close operations.

Here is what this phase of SaaS due diligence involves and how to clarify the true value of your IP:

Intellectual Property(IP)

You should confirm your company’s IP rights, whether it’s patents, trademarks, copyrights, or trade secrets. Verify and inventory the open-source software (OSS) used, for example, AI-generated code.

You should identify whether the third-party software licenses can be transferred to customers. That means that you check for clauses on change of control or other restrictions. Ensure you’ve signed IP agreements for IP developed by employees or contractors.

Customer and Vendor Contracts

Review the contracts that support a smooth transition for your business, whether it’s employee agreements, NDAs, or contractor agreements.

You should watch out for outdated or high-risk contracts with unusual change-of-control or custom pricing terms. Additionally, prepare for any lawsuits, regulatory actions, or employee disputes.

Privacy and Data Compliance

Your SaaS company should comply with applicable data and privacy regulations, including GDPR, CCPA, SOC 2, and other industry-specific standards.

Outline the data security promises your SaaS company makes. Also, list the type of personal information you collect and the people with access to that information.

Commercial and Team Due Diligence

Buyers want to understand the structure of your customer relationship and assess your team structure. You should therefore prepare for their questions about customer concentration and validate the quality and durability of your company’s revenue stream.

Here’s what to prepare ahead of a transaction:

Revenue Quality and Customer Base

Your revenue should be recurring and durable, supported by a high-quality sales pipeline and a low churn rate.

Assess the top contracts, including the renewal terms and concentration. The subscription pricing and plans should also showcase continued growth.

HR and Key Persons

Create an organizational chart outlining the agreements of C-level and key employees, along with their incentive structures.

You should demonstrate leadership continuity and the willingness of key team members to support the M&A transaction.

Common SaaS Due Diligence Red Flags

Some common issues may arise when setting up due diligence for your SaaS company, which can dilute your business value or lead to termination of the deal.

We’ve broken down the top M&A deal killers:

Red Flag Why It Matters to Buyers What Sellers Should Do Before Due Diligence
Change of Control Clauses in Software Agreements If there are restrictions in the software agreements, it can derail the buyer's integration strategy or lead to costly renegotiations. You should leverage tools to audit all open-source software licenses and code.

You can change the provisions in your software agreements when preparing for due diligence.
Inflated SaaS Metrics If MRR and ARR are overstated, it can raise scrutiny of whether the revenue is truly recurring. You should write down how you calculated the MRR, ARR, churn, and net retention.

It’s crucial to track failed payments, contract pauses, and downgrades as well.
Undisclosed Technical Debt If the codebase has outdated frameworks, tangled architecture, or weak documentation, it can signal slow product development. You should review and document your software architecture and code.

Keep a log of the technical debt and what should be replaced first.
Heavy Dependence on Third-Party Tools and APIs If your company relies heavily on a single API, cloud vendor, or data source, it could become risky if the supplier changes pricing or terms. You should map out the key vendors, renewal dates, and fallback options.

Where there’s high dependency, you should negotiate better terms and pricing.
Single Customer Accounts for 10% or More Revenue It’s a clear risk when too much revenue is from one or a few customers. You can broaden the customer base by improving your pipeline balance, cross-selling to a broader customer base, and implementing retention strategies.

Based on our experience, SaaS founders should anticipate common buyer questions and prepare clear documentation. At Exitwise, we help you identify risks and improve the transferability of your M&A transaction.

How to Set Up Your Virtual Data Room Before Diligence Begins

You need to organize documents in the different due diligence categories we’ve explored above. A virtual data room helps you centralize important M&A documents, controls who can view them, and streamlines communication.

Here are the steps to follow:

  1. Define the Scope of the Review: Decide what it should cover and ensure it meets the compliance and risk assessment requirements. You should then decide which parties will review the information, the essential documents, and the level of access to be granted to each group.
  2. Build a Due Diligence Checklist: Group the checklist into categories such as corporate and legal documents, financial records, commercial contracts, and HR and management information.
  3. Gather the Documents: Once your checklist is ready, upload the latest, accurate versions of each document. When you have clean, verified files, you can expedite the due diligence process and reduce unnecessary questions.
  4. Set Permissions and Access Controls: Not every user should have access to all documents, and some files require more control than others. So, you should set permissions based on role and need. If you have sensitive records, such as strategic plans, you may apply stronger access controls, including encryption, download restrictions, watermarks, and expiration settings.
  5. Leverage Platforms: Your virtual data room should support communication where buyers can leave follow-up questions. So, leverage platforms such as Datasite, Intralinks, and Firmex, as well as simpler tools like Dropbox or Google Drive with built-in Q&A features. You can also assign questions to your internal team, track status, and preserve the record of responses.

Frequently Asked Questions

Check out some answers to common questions that SaaS founders ask about the due diligence process:

What Is the Difference Between Buy-Side and Sell-Side Due Diligence?

Buy-side due diligence happens when buyers are considering a potential acquisition. Their objective is to assess the key areas when selecting a company and ensure it aligns well with their overall objectives.

Sell-side due diligence, or reverse due diligence, is the process of assessing your company as if you were the buyer. The goal is to present accurate information to the buyer, helping you secure a successful M&A transaction and close it at the highest possible price.

Both examine the workstreams we’ve discussed above, but with different purposes.

How Long Does SaaS M&A Due Diligence Take?

Every SaaS M&A transaction is different, but the due diligence can take 4 to 6 weeks, depending on:

  • How well you're prepared as a seller.
  • How complex the SaaS transactions are.
  • Whether you’re working with a Saas M&A advisor.

What Documents Do I Need for SaaS Due Diligence?

Most SaaS due diligence needs corporate records, legal agreements, financial statements, IP and cybersecurity documents, and compliance documents.

You can organize these documents in a virtual data room, which can impact the buyer's confidence.

Can a SaaS Company Fail Due Diligence?

Yes, a SaaS company can fail due diligence if you don’t disclose issues or if the business seems unsellable.

The most common reasons are inflated SaaS metrics, unclear IP ownership, massive technical debt, or reliance on a single customer.

What Is a Quality of Earnings Report and Do I Need One?

A Quality of Earnings (QoE) report validates the accuracy of your company’s earnings power. Some of the aspects in the QoE are:

  • Normalized level of the EBITDA.
  • Operating expenses and employee analysis.
  • Normalized levels of the working capital.
  • SaaS metrics such as ARR.

You might need the sell-side QoE to uncover financial issues before the buyer does, justify your asking price, and speed up your sales process.

What Role Does an M&A Advisor Play in Due Diligence?

An M&A advisor helps to keep your deal on track during the due diligence process, protects the deal, and the company’s value you’ve earned.

Here’s how they do that:

  • Create a data room and gather the required documents.
  • Coordinate the documents flow, respond strategically to the buyer's questions, and follow up. They support your company’s positioning and eliminate uncertainty.
  • Anticipate issues early in the negotiations and proactively address them.

Conclusion

Preparing for each SaaS due diligence category makes reviews easier and eliminates buyer uncertainty that slows deals. It’s important to create a virtual room to ensure the documents are complete, organized, and secure.

One pattern we often see is that preparation can help you create leverage in negotiations more than solving problems at the last minute.
