Technical Due Diligence Checklist for Buying or Investing in a Software Company

Meerako — Dallas, TX experts running independent technical due diligence for acquirers and investors.

If you're the one acquiring or investing in a software company — not the founder preparing to be evaluated — you need a practical, executable checklist for running (or commissioning) technical due diligence yourself. This is the buyer-side companion to what a diligence review actually examines: specifically, what to request, who should run it, and which findings genuinely warrant walking away or renegotiating terms.

• What to formally request before diligence begins.
• Who should actually run the technical review, and why it shouldn't be the deal team.
• The red flags that most commonly warrant renegotiation or walking away.
• How to structure findings into an actionable decision, not just a report.

Request codebase access (read access to the actual repository, not just a demo environment), architecture documentation, infrastructure and hosting details, a list of key third-party dependencies and their licensing, security audit history (if any), and access to interview the technical team, not just review artifacts. A target unwilling to provide reasonable access to any of these is itself a meaningful signal.

The technical reviewer should be independent of the deal team's financial incentive to close — an internal engineer with no stake in whether the deal happens, or an external, independent technical due diligence specialist. This independence matters because a reviewer with an incentive to find the deal favorable (or unfavorable) produces a less trustworthy assessment than one whose only job is accurate technical evaluation.

High bus-factor risk combined with key personnel departing post-acquisition — if critical system knowledge lives in one or two people who won't be staying, that's a real, quantifiable risk to price into the deal. Severe, poorly understood technical debt that the target team itself seems unaware of or unable to estimate remediation cost for. Security gaps inconsistent with the company's stated compliance posture — a company claiming SOC 2 readiness with genuine security gaps found in review is a credibility red flag beyond the specific technical issue. Scalability ceilings that would require a costly rebuild to support the acquirer's growth plans for the product.

A good technical due diligence report doesn't just list findings — it translates them into a decision framework: which findings should affect valuation, which should be resolved as a condition of closing, which should become specific representations and warranties in the purchase agreement, and which are genuine deal-breakers versus manageable risks with a clear remediation cost estimate attached.

We run independent technical due diligence for acquirers and investors — reviewing codebase, architecture, security posture, and team dependency risk, then translating findings into a clear, actionable report that supports real negotiation and closing decisions, not just a long list of observations without prioritization.

How long does a thorough technical due diligence review typically take? Depending on codebase size and complexity, typically one to three weeks for a genuinely thorough review — rushing this timeline under deal pressure is a common way real risks get missed.

Should technical due diligence findings be shared with the target company before closing? Generally yes, for findings that will become conditions of closing or affect valuation — transparency here supports a smoother negotiation than surprising the target with undisclosed findings after terms are already set.

Can technical due diligence be run on a codebase using a lot of AI-generated code? Yes, but reviewers should specifically assess the target's code review discipline for AI-assisted development, since this is an increasingly relevant and sometimes under-scrutinized source of technical debt.

What's a reasonable budget for independent technical due diligence relative to deal size? It varies, but for any deal of meaningful size, the cost of a thorough independent review is typically small relative to the financial risk it's protecting against — treat it as risk-priced insurance on the deal, not a corner to cut.

Running technical due diligence well as a buyer or investor requires the right independent reviewer, the right access requested upfront, and a structured way to turn findings into actual deal decisions — valuation adjustments, closing conditions, or a genuine walk-away. Skipping the rigor here is exactly how acquirers end up owning problems they didn't know they were buying.
