Selling Your Business: Six Critical M&A Decisions, Part 4
You have selected a buyer.
The principal commercial terms have been agreed. A term sheet has been signed. Exclusivity is in place.
At this stage, many sellers believe the transaction is largely on track and that the remaining steps are primarily procedural.
In reality, one of the most important phases of the entire transaction is only just beginning.
Due diligence sits at the heart of virtually every M&A transaction. It is the process through which a buyer verifies its assumptions, assesses risks and determines whether the business it intends to acquire is consistent with the picture presented during negotiations.
For sellers, due diligence can be both an opportunity and a risk.
A well-prepared business often emerges from due diligence with its valuation, transaction structure and credibility reinforced.
A poorly prepared business may find itself facing difficult questions, revised commercial terms or, in some cases, a buyer that decides not to proceed at all.
Understanding how buyers approach due diligence is therefore essential for anyone contemplating a sale.
Due Diligence Is About Risk, Not Perfection
One of the most common misconceptions among founders and business owners is that buyers expect a perfect business.
They do not.
Every business has weaknesses. Every business faces challenges. Every business contains some degree of operational, legal, financial or commercial risk.
Experienced buyers understand this.
The objective of due diligence is not to determine whether risks exist. It is to understand what those risks are, how significant they may be and whether they have already been reflected in the transaction terms.
A customer dispute may not concern a buyer.
An undisclosed customer dispute might.
A complex shareholder structure may not prevent a transaction.
An inability to determine who must approve the transaction certainly can.
Buyers generally react more negatively to surprises than to risks themselves.
For sellers, this distinction is important. Identifying and addressing issues before launching a process is often far more effective than attempting to explain them once due diligence is underway.
Transparency and preparation generally create more confidence than perfection ever could.
Buyers Are Verifying the Investment Thesis
By the time due diligence begins, a buyer has usually decided that the business is attractive.
The buyer is not searching for reasons to proceed.
The buyer is searching for reasons why its initial assumptions may be wrong.
This distinction is important.
Throughout the diligence process, buyers are effectively testing the investment thesis that justified the proposed transaction.
Questions commonly include:
- Are revenues as predictable as they appear?
- Are customer relationships secure?
- Can margins be maintained?
- Are growth forecasts realistic?
- Is the management team capable of supporting future expansion?
- Are there risks that have not yet been disclosed?
Due diligence is therefore less about confirming what the buyer already knows and more about identifying what the buyer does not yet know.
For sellers, the objective should be to ensure that the buyer’s assumptions survive scrutiny.
Financial Performance Is Only the Starting Point
Most transactions begin with financial information.
Revenue growth, profitability, cash flow and forecasts often form the basis for preliminary valuation discussions.
However, once due diligence begins, buyers quickly move beyond financial metrics.
A business with strong financial performance may still present significant transaction risks.
Buyers frequently seek to understand:
- the quality and sustainability of earnings;
- customer concentration levels;
- supplier dependencies;
- recurring versus non-recurring revenues;
- working capital requirements;
- historical financial controls;
- forecasting reliability.
The objective is not merely to understand past performance.
The objective is to determine whether future performance is likely to justify the proposed valuation.
Buyers Assess Management as Carefully as the Business
In many transactions, buyers spend as much time evaluating management as they do evaluating financial performance.
This is particularly true where future growth depends heavily on key individuals.
Buyers want to understand whether customer relationships are institutionalised, whether operational knowledge is shared across the organisation and whether the business can continue to perform successfully after closing.
For founder-led businesses, this issue often becomes especially important.
A company that depends entirely on one individual may present a greater risk than a company supported by a broader management team with clearly defined responsibilities.
A strong management team frequently increases buyer confidence.
Excessive dependence on a single founder frequently has the opposite effect.
For sellers, this is another reason why transaction preparation should begin well before a sale process is launched.
Legal Due Diligence Often Reveals Business Risks
Business owners sometimes view legal due diligence as a technical exercise conducted by lawyers.
In reality, legal due diligence often reveals issues that are fundamentally commercial in nature.
Buyers commonly review:
- corporate records;
- commercial contracts;
- employment arrangements;
- financing agreements;
- regulatory matters;
- litigation and disputes;
- intellectual property rights;
- insurance coverage.
The purpose is not simply to identify legal defects.
It is to understand how the business operates and whether critical relationships are adequately protected.
A key customer relationship may depend on a contract nearing expiration.
A valuable software platform may rely on intellectual property that has never been formally assigned to the company.
A founder may possess knowledge that has not been institutionalised within the business.
These are business risks as much as legal risks.
Intellectual Property Can Determine Transaction Value
For startups, technology companies and innovation-driven businesses, intellectual property frequently becomes a central focus of due diligence.
Interestingly, buyers are often less concerned with how innovative the technology is than with whether the company actually owns it.
Particular attention is frequently paid to:
- software development arrangements;
- intellectual property assignments;
- contractor agreements;
- open-source software usage;
- trademarks and branding;
- proprietary technology.
Uncertainty regarding ownership can significantly increase transaction risk.
In some cases, buyers may be unwilling to proceed until ownership issues have been resolved.
For growth companies and venture-backed businesses, intellectual property diligence often becomes one of the most important workstreams in the entire transaction.
Cap Table Integrity Matters
Many founders assume that buyer attention will focus primarily on products, customers and growth.
Yet one of the most important diligence topics in startup transactions is often the cap table.
Buyers need to understand precisely who owns the company and what rights attach to that ownership.
Multiple financing rounds, convertible instruments, employee participation plans and bespoke shareholder arrangements can create considerable complexity if documentation has not been maintained carefully.
Buyers commonly review:
- share ownership records;
- share issuances;
- option plans;
- conversion rights;
- investor consent requirements;
- drag-along rights;
- transfer restrictions.
A buyer may be entirely comfortable with a complex ownership structure.
What buyers generally dislike is uncertainty regarding ownership or transaction execution.
For that reason, cap table integrity often matters more than cap table simplicity.
The Data Room Says More Than Many Sellers Realise
Most due diligence exercises are conducted through a virtual data room.
At first glance, the data room may appear to be little more than an administrative tool.
In practice, it often shapes a buyer’s perception of the transaction process.
Well-organised documentation demonstrates preparation, professionalism and control. Poorly organised documentation can create the opposite impression.
A buyer who repeatedly encounters missing documents, inconsistent information or delayed responses may begin to question whether similar issues exist elsewhere in the business.
For sellers, a well-prepared data room does more than improve efficiency.
It helps build confidence.
Due Diligence Influences Negotiations
Many sellers assume that commercial terms have largely been agreed once the term sheet has been signed.
In practice, due diligence frequently continues to influence negotiations.
Material findings may affect:
- purchase price;
- earn-out structures;
- escrow arrangements;
- warranty packages;
- indemnity protections;
- closing conditions.
This does not mean every issue leads to renegotiation.
However, buyers generally expect transaction terms to reflect the risks identified during diligence.
The fewer surprises that emerge, the more likely it becomes that the transaction proceeds on the originally contemplated terms.
The Best Due Diligence Processes Contain Few Surprises
Experienced dealmakers often describe successful due diligence processes in remarkably similar terms.
They are not necessarily short.
They are not necessarily simple.
But they contain few surprises.
By the time a transaction reaches advanced stages, sellers should ideally have a good understanding of the questions buyers are likely to ask and the issues buyers are likely to identify.
The objective is not to eliminate every risk.
The objective is to ensure that significant issues have already been identified, analysed and, where possible, addressed.
When that happens, due diligence becomes what it should be: a verification exercise rather than a discovery exercise.
Conclusion
Due diligence is where buyers test assumptions, verify value and assess risk.
For sellers, it is often the stage that determines whether a transaction proceeds smoothly, becomes mired in renegotiations or fails altogether.
The businesses that perform best during due diligence are rarely perfect.
They are prepared.
In many transactions, due diligence does not create problems.
It reveals them.
Sellers who understand this distinction are generally better positioned to preserve valuation, maintain negotiating leverage and keep a transaction on track.
Because in M&A, buyers do not expect perfection.
They expect transparency, organisation and a clear understanding of the business they are acquiring.
