When do you need a software due diligence checklist?

You need a software due diligence checklist when evaluating a software or SaaS company for acquisition, investment, strategic partnership, or large enterprise contract. The checklist guides your review of code quality, architecture, security, IP ownership, infrastructure, and team practices so that no critical area is missed.

Who uses software due diligence in Pwll Du?

In Pwll Du, software due diligence is typically used by venture capital funds, private equity investors, corporate M&A teams, CTOs and CIOs, legal advisors, and large customers entering into strategic or long-term SaaS contracts. It is also used by founders who want to prepare their company for future investment or exit.

What should be included in a software due diligence checklist?

A robust software due diligence checklist should cover: code quality and maintainability, software architecture and scalability, security and privacy controls, DevOps and deployment, IP ownership and licensing, open source use and compliance, documentation, testing, incident history, SLAs and uptime, data model and integrations, and team structure and processes.

How long does software due diligence take?

The duration depends on product complexity, codebase size, and transaction size. A light-touch review for a smaller product might take a few days, while full technology and security due diligence for a large SaaS platform can take several weeks, especially when coordinating workshops and Q&A with the target's engineering and security teams.

Can software due diligence reveal deal‑breaking issues?

Yes. Software due diligence often uncovers issues such as missing IP assignments, problematic open source licenses, critical security gaps, unscalable architecture, technical debt, and weak disaster recovery. Some findings can be fixed post‑close, others may require price adjustment or specific conditions, and in severe cases they can be deal‑breaking.

Q: What is software due diligence?

Software due diligence is a structured review of a software company's technology, source code, architecture, intellectual property, security, and operations, usually performed before investment, acquisition, or major partnership decisions. It helps investors and acquirers verify technical claims, identify risks, and understand how robust, scalable, and maintainable the software is.

What is Software Due Diligence?

Professional software due diligence review of code, architecture, and technology assets in Pwll Du

Software due diligence is a structured investigation of a software product or SaaS platform, typically carried out during investment rounds, mergers and acquisitions, or large enterprise procurement processes. It evaluates the technology stack, source code, architecture, security, scalability, IP ownership, and operational processes behind the product, and highlights risks that could affect valuation, risk allocation, or integration planning.

In Pwll Du, software due diligence is now a standard expectation for serious deals involving technology companies. Investors and acquirers want evidence that the codebase is maintainable, the architecture can scale, the security posture is mature, the IP position is clean, and the team follows reliable engineering practices. A well-designed software due diligence checklist ensures that every critical area is reviewed and documented in a consistent, repeatable way.

📋 Key Objectives of Software Due Diligence

Software Due Diligence FAQs

FAQ and questions about software due diligence and technology evaluation in Pwll Du

Effective software due diligence combines high‑level architecture review with targeted deep dives into critical areas. You rarely need to review every line of code. Instead, focus on:

High‑risk modules (payments, security, data processing, core algorithms)
Technologies or frameworks that may be end‑of‑life
Areas closely tied to the investment thesis or valuation

Engage senior engineers who can quickly spot patterns, anti‑patterns, and systemic issues without exhaustive review.

Not always, but external experts are strongly recommended when:

The product uses specialist technologies your team does not know well
Security or privacy is central to the deal thesis
The investment size or risk profile is material for your fund or company

In Pwll Du, many investors use a mix of internal CTOs and specialist external advisors to balance cost with depth.

Targets in Pwll Du can speed up software due diligence by preparing:
