What Is Due Diligence in SaaS?
Due diligence in the SaaS space is the structured process of thoroughly evaluating a software-as-a-service company before an acquisition, merger, or investment. The goal is to gain a clear understanding of the company’s financial health, operational efficiency, technical reliability, and legal standing, ensuring there are no hidden risks before any deal is finalized.
For SaaS companies, due diligence typically covers several key areas:
Financial due diligence: Reviewing revenue streams, subscription models, churn rates, and customer lifetime value (CLV) to confirm financial accuracy and sustainability.
Operational due diligence: Examining team structure, workflows, and strategic direction to gage how effectively the company runs its operations.
Technical due diligence: Assessing the platform’s architecture, infrastructure, and scalability to identify any technical debt or security vulnerabilities.
Legal due diligence: Verifying intellectual property ownership, customer and vendor contracts, data protection policies, and compliance with relevant regulations.
In essence, SaaS due diligence gives buyers and investors a complete picture of what they’re acquiring, while allowing sellers to showcase the true value and potential of their recurring revenue model.
How to Prepare for Preliminary Due Diligence
Set up your documents and data first. When everything is organized, a SaaS due diligence review moves much faster, whether it’s for fundraising or an exit.
Here’s how you can set the groundwork for a strong preliminary due diligence process:
Gather essential documents based on your goal
If you’re fundraising: Prepare agreements such as Investor Rights Agreements (IRAs), Preferred Stock Purchase Agreements (SPAs), and Voting Agreements from prior rounds.
If you’re fundraising or selling: Include your Certificate of Incorporation that outlines authorized shares, along with vital legal documents like customer and vendor contracts, employee agreements, and compliance records (GDPR, CCPA, etc.).
Organize your company structure
Create up-to-date organizational charts for each department, along with an overview of the company as a whole. Pair this with a detailed employee census listing each team member’s role, responsibilities, hire date, and salary range. This transparency helps investors or buyers understand your operational hierarchy and workforce composition.
Clean and standardize your data systems
Your CRM (Customer Relationship Management) system plays a major role in due diligence. Ensure it’s well-maintained and reflects accurate, real-time data on customers, revenue, and retention. Clear segmentation and performance insights give potential investors a strong grasp of your business health and growth potential.
Taking these steps upfront not only accelerates the due diligence phase but also demonstrates professionalism, operational maturity, and readiness to scale. It shows stakeholders that your organization values transparency and governance, key traits that build trust in any SaaS partnership or investment opportunity.

What the Initial Review Process Looks Like
The initial review phase of SaaS due diligence goes beyond numbers; it’s your chance to see if a potential buyer truly aligns with your company’s values, goals, and long-term vision. This stage helps you identify not just a financial investor but a strategic partner who understands your product, market, and mission.
Start by asking key questions to gauge their experience and compatibility:
What’s their acquisition strategy, and how does your business fit in?
Do they have prior experience in your niche, and what were the outcomes?
Will your company remain independent or merge with another portfolio firm?
How do they handle team transitions and culture post-acquisition?
What does their typical deal structure and timeline look like?
Don’t hesitate to verify their credibility, request recent references, or connect with founders they’ve worked with. Current feedback reveals far more than outdated success stories.
If the discussions go well, be prepared for a follow-up call or initial data request. The acquiring firm may ask for deeper insights into your product performance, customer segments, or revenue trends.
This stage isn’t just about being assessed; it’s a two-way evaluation to ensure the buyer is the right fit for your company’s next chapter.
Key Components of a SaaS Due Diligence Checklist
A thorough SaaS due diligence checklist ensures that both buyers and sellers gain a complete understanding of the company’s financial, operational, and technical health before a transaction takes place. It helps identify potential risks, verify claims, and build transparency throughout the acquisition process. Below are the core components every SaaS due diligence checklist should include:
1. Financial Due Diligence
Financial health forms the backbone of any acquisition. The goal is to validate the company’s revenue streams, cost structure, and overall profitability.
Key items to review include:
Revenue breakdowns by subscription tiers, customer segments, and geographies
Recurring revenue metrics such as MRR (Monthly Recurring Revenue) and ARR (Annual Recurring Revenue)
Churn and retention rates to assess long-term customer stability
Expense reports and cost of acquisition (CAC) to determine profitability per customer
Cash flow statements, tax filings, and debt obligations for transparency
A detailed financial audit reveals how efficiently the company generates, manages, and sustains revenue over time.
2. Product and Technology Review
Since software is the core of a SaaS business, buyers need to evaluate the technology stack, product architecture, and scalability.
Important checkpoints include:
Code quality, documentation, and version control practices
Hosting environment and infrastructure reliability (e.g., AWS, Azure, or GCP)
Product roadmap and feature backlog
Data architecture, API integrations, and automation levels
Software licensing, IP ownership, and any third-party dependencies
This review ensures the product is stable, secure, and built for long-term growth without technical debt.
3. Legal and Compliance Review
Legal due diligence helps confirm that the company operates within the boundaries of relevant laws and industry regulations.
Critical documents to verify include:
Corporate formation records and shareholder agreements
Intellectual property registrations and patents
Customer and vendor contracts
Employment agreements and NDAs
Compliance with GDPR, CCPA, SOC 2, or ISO 27001 (depending on geography and data sensitivity)
This process protects both parties from unforeseen liabilities and ensures regulatory integrity.
4. Customer and Market Analysis
Understanding the customer base is key to evaluating business sustainability.
Areas to examine:
Customer demographics, segments, and usage patterns
Net Promoter Score (NPS) and customer satisfaction surveys
Contract renewal and expansion rates
Customer support performance and SLAs
Competitive positioning and market share
These insights reflect how well the company serves its users and whether it has a strong market presence or untapped potential.
5. Operational and Team Evaluation
Behind every successful SaaS product is a capable team and well-defined processes. This part of the checklist focuses on:
Organizational structure and key personnel
Team size, roles, and attrition rates
Hiring strategy and training programs
Internal workflows, automation tools, and performance metrics
Assessing the team’s stability and operational efficiency helps forecast the company’s ability to sustain performance post-acquisition.
6. Security and Data Protection
Data is the lifeblood of SaaS. A breach or weak control can derail even the most promising deal.
Key areas include:
Data encryption standards and backup policies
Incident response and breach management plans
Access control mechanisms and authentication practices
Regular penetration tests and third-party security audits
Vendor risk management and cloud security configurations
This ensures the SaaS provider follows best practices for protecting sensitive data and customer trust.

Finally, a strong due diligence checklist examines the company’s scalability and growth potential.
Metrics to assess:
Conversion rates, upsell/cross-sell performance
Market expansion opportunities
Sales pipeline and customer acquisition strategies
Product adoption metrics and lifetime value (LTV) trends
Evaluating these factors provides a clear picture of future profitability and whether the SaaS business is positioned for long-term success.
As you evaluate these key components, keeping every piece of information aligned and verifiable can be challenging, especially when multiple vendors, stakeholders, and compliance frameworks are involved.
