The pressure to do due diligence faster and better is ramping up, as a lack of proper due diligence can derail the deal. McKinsey’s research on why deals fall apart found that more than half of unsuccessful deals fail because of problems that could’ve been caught early on. That’s exactly why more and more teams here in the UK are turning to due diligence software now.

Here are our key findings of some of the best due diligence software solutions across categories like VDRs, KYC, TPRM, and more. Read on to see which ones stand out, based on clients’ reviews, features they offer, pricing plans, etc. 

What due diligence software does and when you need it

Due diligence software is a tool that helps you investigate and verify a company’s information before you buy or invest in it. The right due diligence software helps teams conduct accurate reviews and manage everything they need before making a serious business decision. When all the checks and files are organized, work moves faster, and there’s less room for human errors.

This software is getting popular as the mergers and acquisitions market is expected to grow. In fact, Q3 of 2025 saw a 26.8% rise in deal value. Moreover, a recent Deloitte survey shows a positive sentiment towards deal dynamics in 2026. 90% of PE respondents and 80% of corporate respondents said they expect an increase in deal numbers in the next year.

Keeping that in mind, companies will be looking for software that offers automated workflows, risk mitigation, and data analytics to drive more informed decisions. That’s exactly what due diligence software offers. Let’s explore its key features in more detail. If you’re choosing your first solution, you can take a look at examples and selection criteria here.

Mistakes to avoid

Even the top-rated software won’t benefit the business if the processes underneath it aren’t solid and efficient. These are the common challenges to avoid when selecting software for better due diligence:

1. Choosing features over data quality and coverage

It’s tempting to pick the platform with the longest feature list, but that’s often a mistake. What really matters is whether the underlying data is current and complete. This is especially critical for KYC and AML tools as businesses need comprehensive coverage of sanctions lists, adverse media, and corporate registries. A beautiful dashboard means nothing if it’s showing you outdated information.

2. Treating due diligence as a one-time event vs continuous monitoring

Risk isn’t static. Your vendors evolve, your customers’ situations change, and the regulatory landscape evolves. Your due diligence software needs to support ongoing monitoring rather than just initial screening.

3. Underestimating change management and training

The software is only as effective as the people using it. Many programs fail because teams don’t understand the workflows or find workarounds because they weren’t properly trained. Build comprehensive training into your rollout plan and make sure everyone understands not just the how, but the why behind each step.

4. Overcomplicating risk scoring without governance

Automated risk scoring should make your life easier, not harder. But when organizations layer on complex rules without clear ownership or documentation, the system becomes a black box. Keep your scoring logic transparent and maintainable. If your team can’t explain why something got flagged, your governance model needs work.

5. Ignoring evidence retention and auditability

Can you prove what checks you performed and when? If regulators or auditors ask for documentation from last year, can you produce it quickly? Your software needs robust audit trails, version control, and secure evidence storage. Without these, you’re building on sand, and no matter how thorough your current process feels.

If you want to dig deeper into building a solid framework, the VC due diligence checklist is worth exploring, it covers a lot of these fundamentals in more detail.

FAQs

How long does it typically take to implement due diligence software?

It depends on your organization’s complexity, but expect 2-6 months for a solid implementation. That includes data migration, workflow configuration, integration with existing systems, and training.

How much does due diligence software cost?

Pricing varies. Virtual data rooms often use project-based pricing, while KYC and AML tools follow usage-based models. Enterprise TPRM tools and AI due diligence software usually use annual subscriptions.

How do we measure due diligence software efficiency?

Start with baseline metrics before implementation: How long does vendor approval take? What percentage of your vendors have current documentation? How many hours go into each M&A deal? Then track the same metrics quarterly after rollout.

Also monitor user adoption rates. If people are working around the system, something’s wrong. The best indicators are often qualitative too: Are auditors satisfied? Do deal teams feel more confident? Has your risk committee noticed better insights? If the answer is Yes, the software was a good choice.
