Software Due Diligence: A Strategic Guide for Investors, VCs & M&A Leaders in 2026

The software industry has increasingly made up for a larger percentage of total revenue of many tech-first companies. From SaaS platforms to enterprise tools, the value of a business often depends on the quality, performance, and reliability of its software. Therefore, financial analysis alone is not enough to make safe investment decisions.

Software due diligence which is also called technology software due diligence or SW DD, focuses on evaluating a company’s software products, systems, and platforms and helps investors, VCs, as well as M&A teams identify potential risks, understand growth potential, and make informed decisions before an acquisition, funding, or IPO.

Dextralabs helps investors manage technology-related risks with thorough software due diligence. By analyzing software performance, architecture, team capabilities, and scalability, Dextralabs provides clear insights so investors can confidently back companies with strong, reliable software assets.

What is Software Due Diligence?

Software due diligence is an act of evaluating the software that a company is selling instead of the tools that it uses on a day-to-day basis. How well the software functions, how good it is, and what risks are associated with it should be known before making a major investment.

This evaluation is important for several situations:

• M&A transactions: Check the company’s software before buying or merging.
• Significant investments: Ensure the software is reliable and scalable before funding.
• IPO readiness: Verify that the software can support growth and meet investor expectations.

It’s helpful to understand how software due diligence differs from other types of checks:

• Technical due diligence vs software due diligence: Technical due diligence examines the overall technology stack, both internal and external. Software due diligence pays special attention to the revenue-generating products.
  
• Financial due diligence vs software due diligence: Financial due diligence reviews numbers and accounts. Software due diligence reviews the actual product to see if it delivers value, is scalable, and can support future growth.

In short, software due diligence M&A and investments give investors confidence that the software being bought or funded is strong, secure, and built to last. It’s a key part of understanding a company’s true value and risk.

A well-defined software due diligence checklist enables investors, VCs, and M&A teams to assess software quickly and effectively. At Dextralabs, we adopt a structured methodology to address all the important areas of a company’s software products and systems.

Key elements of a software due diligence checklist help us understand the real health and risks of the software before investing. Here’s what we focus on:

• Code maintainability: We check how easy it is to update, fix, or add new features to the software without causing problems.
  
• Architecture scalability: We see if the software design can handle growth and more users as the business expands.
  
• Dependency risks: We identify any risks from third-party libraries, frameworks, or vendor tools that the software relies on.
  
• Open-source compliance: We make sure all open-source components follow proper licenses and are safe to use.
  
• Security posture: We review data protection, cybersecurity measures, and compliance with standards like ISO, NIST, and GDPR.
  
• Technical debt: We look for temporary fixes, old code, or legacy issues that could slow down future updates or increase costs.
  
• Infrastructure sustainability: We check cloud setups, DevOps pipelines, and overall operations to ensure the software can scale safely and efficiently.

This software due diligence checklist provides investors with a concise, practical perspective of strengths, weaknesses, and risks of the software, which they can use to make confident decisions before M&A, funding, or IPO.

Software Due Diligence in M&A Transactions

Software due diligence in M&A is a must whenever we’re looking at buying a tech or software-driven company. It helps us really understand the value of the software, spot hidden risks, and make smarter investment decisions.

• Impact on valuation negotiations: By showing the software’s strengths, weaknesses, and any technical debt, we can set a fair price and also have better leverage when negotiating the deal.

• Role in deal structuring: The insights we get from software evaluations guide deal terms, payment plans, and even contingency strategies tied to how the software performs.

• Risk mitigation for acquirers: It’s crucial to catch vulnerabilities, licensing issues, or architecture limits early on, so we can reduce surprises after the acquisition and feel more confident about the investment.
  
• Influence on post-merger integration success: It would be easier to think ahead and plan integration, align the team, and maintain business continuity when you know the software’s architecture, dependencies, and scalability upfront.

To investors and corporate strategy teams, Software due diligence M&A is not a choice that is optional but rather a necessity that protects investment, improves results and facilitates the post-acquisition operations.
