Download Software Due Diligence ChecklistWhat is Software Due Diligence?
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 Ash, 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
- Verify technical claims about performance, scalability, and product roadmap
- Identify technology risks that could affect uptime, security, or customer satisfaction
- Confirm IP ownership and licensing posture, including open source compliance
- Evaluate engineering practices, DevOps maturity, and release management
- Support valuation by understanding real technical assets and liabilities
- Inform integration plans and post‑deal technology strategy
Core Software Due Diligence Areas
| Due Diligence Area | Focus | Examples | Typical Stakeholders |
|---|---|---|---|
| Code & Architecture | Maintainability, scalability, complexity | Code review, architecture diagrams, technical debt | CTO, senior engineers, external technical advisors |
| Security & Privacy | Application security, data protection | Vulnerabilities, encryption, access control, GDPR | Security leads, compliance officers, CISOs |
| IP & Licensing | Ownership, assignments, third‑party usage | Employment contracts, contractor agreements, OSS | Legal counsel, IP specialists, outside lawyers |
| Operations & DevOps | Reliability, deployment, monitoring | CI/CD, incident history, SRE practices, SLAs | Engineering managers, DevOps leads, SRE |
| Data & Integrations | Data model, APIs, external systems | Schema design, ETL, inbound/outbound integrations | Architects, data engineers, product owners |
✅ Why Use a Structured Checklist?
- Ensures consistent coverage across different deals and targets
- Reduces the risk of missing critical issues under time pressure
- Makes it easier to compare multiple targets or options
- Provides a clear audit trail for investment or board committees
- Supports transparent communication with the target’s team
Software Due Diligence Checklist: Key Sections
1. Codebase & Architecture
- Repository overview: mono‑repo vs multi‑repo, languages and frameworks
- Code quality indicators: tests, linting, static analysis, style consistency
- Ownership and bus‑factor: key modules and who understands them
- Architecture patterns: microservices vs monolith, event‑driven, domain‑driven design
- Scalability and performance patterns: caching, queues, async workloads
- Technical debt areas and big‑bang rewrites vs incremental refactors
2. Infrastructure & DevOps
- Hosting model: on‑prem, cloud (AWS, Azure, GCP), hybrid
- Infrastructure as Code: Terraform, CloudFormation, Ansible, etc.
- Deployment pipelines: CI/CD tooling, rollback strategy, approvals
- Monitoring & observability: logs, metrics, traces, alerting thresholds
- Environments: dev, test, staging, production, data separation
- Disaster recovery: RPO/RTO targets, backup frequency, restoration tests
3. Security, Privacy & Compliance
- Security governance: policies, secure SDLC, threat modelling
- Identity & access: IAM, least privilege, SSO, MFA enforcement
- Vulnerability management: scanning tools, patch cycles, penetration tests
- Data protection: encryption at rest/in transit, key management, secrets storage
- Privacy compliance: GDPR/UK‑GDPR, CCPA, data subject rights, DPA agreements
- Incident history: breaches, severity, lessons learned, process improvements
4. IP Ownership & Open Source
- Employment and contractor agreements: IP assignment clauses in Ash
- Founders, early contractors, and any missing IP paperwork
- Use of open source: dependency inventory, license types, copyleft exposure
- Third‑party components and SaaS: contracts, SLAs, data processing
- Trademarks, registered designs, and patents (if applicable)
- Past or ongoing IP disputes, claims, or takedown notices
5. Product, Roadmap & Quality
- Product maturity: MVP vs stable product vs legacy platform
- Backlog and roadmap: planned features, re‑platforming, technical debt work
- Testing strategy: unit, integration, end‑to‑end, performance, regression
- Release cadence: how often, failure rate, hotfix handling
- Customer‑facing SLAs, uptime targets, and historical uptime data
- Customer feedback loops: product analytics, NPS, support tickets
⚠️ Common Red Flags in Software Due Diligence
- No clear IP assignments for key founders, contractors, or overseas teams
- Heavy reliance on a single developer or unmaintained legacy stack
- Unpatched critical vulnerabilities or absent security processes
- Unscalable architecture that cannot support projected growth
- No automated tests or fragile, manual release process
- Copyleft open source licenses embedded in core proprietary code

⚠️ Legal and Regulatory Considerations
Software due diligence touches intellectual property, data protection, and regulatory compliance. In Ash, ensure that source code access, data room sharing, and cross‑border data transfers comply with confidentiality obligations, NDAs, and privacy laws. Always involve experienced legal counsel for IP, privacy, and regulatory issues, and make sure your NDA and engagement terms clearly define the purpose and limits of due diligence access.
Software Due Diligence FAQs
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 Ash, many investors use a mix of internal CTOs and specialist external advisors to balance cost with depth.
Targets in Ash can speed up software due diligence by preparing:
- Up‑to‑date architecture diagrams and environment overviews
- Clean, well‑organised repositories with clear README files
- Security policies, penetration test results, and incident logs
- IP assignment documents for all employees and contractors
- Current dependency list and open source license report
Preparation can turn due diligence from a stressful scramble into a positive demonstration of maturity.
You can reuse the structure of your checklist and some generic assessments, but each deal in Ash has unique context. Always re‑validate:
- Current codebase and deployments (things change fast)
- New features, integrations, and dependencies
- Recent incidents, audits, or regulatory changes
Think of your checklist as a living framework that evolves with each deal and each learning.
