Before You Buy a Business: What Clients Need to Know About Due Diligence in Mergers & Acquisitions

What this means

When buying a business, many clients focus on the opportunity — the growth potential, the customer base, the revenue, or the strategic fit. But one of the most important questions is often overlooked: what risks are sitting behind the business that are not obvious at first glance?

That is where due diligence matters. It helps buyers understand not just what they are acquiring, but what they may also be taking on.

The big idea

Clients often think due diligence is simply about "checking the paperwork" before the deal goes through. In reality, it is much more important than that.

Due diligence is the stage where buyers start to see whether the transaction makes sense at the agreed price, on the agreed structure, and with the level of risk they are prepared to accept. It is also where many of the most serious issues first come into focus — issues that can affect completion, business continuity, or the value of the deal itself.

Who this affects

• Owners buying another business for growth A target may look like a natural expansion opportunity, but hidden liabilities, approval issues or contract problems can quickly turn a promising acquisition into a difficult one.
• Private buyers and investors entering a business for the first time Clients investing in a private business often rely heavily on management explanations and headline figures. That is exactly where careful review becomes critical.
• Family groups, founders and business partners considering a strategic acquisition Where a deal is being driven by long-term growth plans, succession planning, or a new market entry, the legal and structural issues behind the acquisition can be just as important as the commercial upside.

What to watch for

• The business may not be as straightforward as it looks A target can present well commercially while still carrying legal, tax, employment or regulatory issues that are not immediately visible. Strong revenue does not always mean a clean legal position.
• Some risks only become clear when the transaction is already moving Clients are often surprised to learn that key contracts may require consent, licences may not transfer easily, or regulators may need to be involved before completion can occur.
• Employee and compliance issues can be expensive Payroll problems, contractor arrangements, superannuation issues, workplace claims, privacy concerns and internal compliance gaps can all affect value and post-completion risk.
• Not every risk should be treated the same way Some risks may be manageable. Others may justify a price adjustment, stronger contractual protection, delayed completion, or a rethink of the transaction entirely.
• The goal is informed decision-making Good due diligence is not designed to create alarm. It is designed to help the buyer make a confident and commercially sensible decision with a clear understanding of what needs to be managed.

Common traps

• Falling in love with the deal before properly testing the risk
• Assuming management explanations are enough without careful legal and commercial review
• Focusing on the purchase price without understanding potential inherited liabilities
• Treating due diligence as a late-stage task instead of an early strategic priority
• Overlooking how legal findings should affect negotiation, structure and contractual protection

Why this matters

The most expensive M&A issues are often not the ones discussed at the start of the transaction. They are the issues that emerge later — after terms have been agreed, leverage has weakened, and the buyer is already committed to moving forward.

That is why due diligence should be viewed as more than a transaction formality. It is one of the clearest opportunities a buyer has to understand the real position, identify where the pressure points are, and decide how the deal should proceed.

For many clients, the real value of due diligence is not simply finding a problem. It is understanding what that problem means — commercially, legally and practically.

What to do next

• Consider the legal and commercial risks before becoming too committed to the transaction
• Identify early whether approvals, key contracts or compliance issues may affect the deal
• Review what protections may be needed if risk areas are uncovered
• Make sure the transaction documents reflect the real findings, not just the original assumptions
• Speak with experienced advisers before the deal moves too far ahead
