The Role of Due Diligence in Selling a Software Company

In the sale of a software company, due diligence is not just a procedural step — it is the crucible through which the deal is tested, validated, and ultimately shaped. For founders and CEOs, understanding the role of due diligence is essential to both maximizing valuation and ensuring a smooth transaction. Done right, it builds trust, uncovers risks before they become deal-breakers, and positions the company as a credible, acquisition-ready asset.

This article explores the strategic importance of due diligence in software M&A, what buyers are really looking for, and how sellers can prepare to navigate this critical phase with confidence.

Why Due Diligence Matters in Software M&A

Due diligence is the buyer’s opportunity to verify the claims made by the seller — from financial performance and customer contracts to intellectual property and codebase integrity. But for sellers, it’s also a chance to demonstrate operational maturity, reduce perceived risk, and justify premium valuation multiples.

In software transactions, where intangible assets dominate and recurring revenue models are common, the due diligence process often goes deeper than in traditional industries. Buyers — whether private equity firms, strategic acquirers, or growth investors — are not just buying code. They’re buying future cash flows, customer relationships, and scalable infrastructure.

As we’ve outlined in Due Diligence Checklist for Software (SaaS) Companies, the process typically spans several domains:

• Financials: Revenue recognition, deferred revenue, ARR/MRR trends, churn, and CAC/LTV metrics
• Legal: IP ownership, customer and vendor contracts, employment agreements, and compliance
• Technology: Code quality, scalability, technical debt, and third-party dependencies
• Operational: Team structure, key person risk, and internal systems/processes

Pre-LOI vs. Post-LOI Due Diligence

While most due diligence occurs after a Letter of Intent (LOI) is signed, savvy sellers increasingly conduct internal diligence before going to market. This pre-LOI preparation — sometimes called “reverse diligence” — allows sellers to identify and address red flags proactively, reducing the risk of retrading or deal collapse later.

As discussed in Completing Due Diligence Before the LOI, this early effort can also accelerate the deal timeline and increase buyer confidence. For example, a seller who can provide clean, GAAP-compliant financials and a clear IP chain of title will stand out in a crowded market.

What Buyers Are Really Looking For

Buyers approach due diligence with a dual lens: validation and risk mitigation. They want to confirm that the business is performing as advertised — and that there are no hidden liabilities that could impair future value.

In software deals, common buyer concerns include:

• IP Ownership: Were all developers (including contractors) under proper IP assignment agreements?
• Revenue Quality: Are revenues recurring, diversified, and contractually secure?
• Customer Concentration: Is the business overly reliant on a few key accounts?
• Technical Risk: Is the codebase maintainable, secure, and free of open-source licensing issues?
• Compliance: Are data privacy policies (e.g., GDPR, SOC 2) in place and enforced?

Failing to address these areas can lead to valuation discounts, escrow holdbacks, or even deal termination. Conversely, demonstrating strength in these areas can justify a higher multiple and more favorable terms.

How Sellers Can Prepare

Preparation is the seller’s best defense — and offense — in due diligence. At iMerge, we often advise clients to begin preparing 6–12 months before going to market. This allows time to clean up financials, resolve legal gaps, and document key processes.

Key steps include:

• Audit Financials: Ensure revenue recognition aligns with GAAP and that key metrics (ARR, churn, CAC) are clearly defined and defensible.
• Secure IP: Confirm that all code contributors have signed IP assignment agreements. Address any legacy contractor issues.
• Organize Contracts: Centralize customer, vendor, and employee agreements. Flag any change-of-control clauses.
• Document Tech Stack: Provide a clear architecture overview, third-party dependencies, and any known technical debt.
• Prepare a Data Room: Create a secure, well-organized virtual data room with indexed folders and version-controlled documents.

In some cases, sellers may also commission a Quality of Earnings (QoE) report to preempt buyer concerns and streamline financial diligence.

Strategic Value of a Well-Run Diligence Process

Beyond risk mitigation, due diligence is a signaling mechanism. A well-prepared seller signals professionalism, transparency, and operational discipline — all of which increase buyer confidence and reduce perceived risk. This, in turn, can lead to:

• Higher valuation multiples
• Faster deal timelines
• Fewer post-closing disputes
• More favorable earn-out or rollover terms

Firms like iMerge specialize in helping software founders navigate this process — not just by managing the data room, but by anticipating buyer concerns, crafting the narrative, and ensuring that diligence supports the valuation story.

Case in Point: A SaaS Exit with Preemptive Diligence

Consider a mid-market SaaS company with $8M ARR and 90% gross margins. Before going to market, the founder worked with iMerge to conduct a pre-sale diligence review. This uncovered several issues: a contractor who hadn’t signed an IP assignment, inconsistent revenue recognition practices, and a customer contract with a problematic change-of-control clause.

By addressing these issues before engaging buyers, the company avoided late-stage surprises. The result? A competitive process with multiple offers, a 9.5x ARR exit, and a clean closing with minimal escrow.

Conclusion

Due diligence is not a hurdle to clear — it’s a strategic phase that can make or break a software M&A transaction. For founders, it’s an opportunity to showcase the strength of the business, reduce buyer uncertainty, and command a premium valuation.

Whether you’re preparing for a full exit or exploring strategic options, early diligence preparation is one of the highest-ROI investments you can make.
