What Is Due Diligence When Selling a Company?
Selling a company isn’t just about getting an offer.
It’s about surviving the stage that comes next.
That stage is due diligence — the most intense, revealing, and make-or-break part of the sale process.
Many founders underestimate it.
Some avoid preparing for it altogether.
And that’s often where good deals die.
What Is Due Diligence?
Due diligence is the phase where a buyer takes a deep look at your business before finalising the deal.
It’s their way of asking:
“Is this business really what it claims to be?”
They want to test the numbers, the claims, the risks — and most importantly, whether the business can keep running without you.
What Does a Buyer Look At? Understanding the Due Diligence Process in Business Sales
When it comes to selling a business, the period of due diligence is a critical phase that can make or break the deal. Due diligence is the comprehensive appraisal conducted by a prospective buyer to establish the business's assets, liabilities, and evaluate its commercial potential. But what exactly does a buyer scrutinize during this process? This blog post delves into the key aspects that buyers examine and why founders often struggle with due diligence.
Financials: The Foundation of Due Diligence
One of the primary areas of focus for any buyer is the financial health of the business. This includes a thorough examination of financial statements to verify their accuracy and to identify any concerning trends. Buyers will look into profit margins, cash flow, and debt levels to assess the company's financial stability. The due diligence process explained in financial terms is essentially a deep dive into the numbers to ensure there are no hidden surprises that could affect the value of the business.
Operations: The Engine of the Business
Operational due diligence evaluates how the business functions on a day-to-day basis. Buyers want to know if the company's processes are repeatable, scalable, and well-documented. They will look at the efficiency and reliability of operations to determine if the business can sustain and grow its performance over time. For a buyer, understanding the operational mechanics is crucial to gauge the potential for future growth and profitability.
Legal & Compliance: Ensuring Everything Is Above Board
Legal and compliance due diligence involves reviewing all contracts, liabilities, and intellectual property to ensure there are no legal encumbrances that could impact the transaction. This includes examining any ongoing disputes and ensuring that the business is in compliance with all relevant laws and regulations. The buyer's due diligence checklist typically includes a detailed look at the company's legal standing to avoid any potential legal issues post-acquisition.
People & HR: The Human Element
The human resources aspect of due diligence focuses on the people within the organization. Buyers will assess the roles and responsibilities of the staff, the strength of employment contracts, and the reliance on key personnel. It's essential for buyers to understand the company's culture and the team's ability to drive the business forward. This is particularly important in founder-led businesses, where much of the critical knowledge may reside with a few individuals.
Customers: The Lifeblood of the Business
Customer due diligence is about analyzing customer retention rates, concentration, and the quality of earnings. Buyers want to ensure that the business has a loyal customer base and that there isn't an overreliance on a small number of customers for the majority of the revenue. A diversified and stable customer base is often seen as a sign of a healthy, resilient business.
Technology/IP: Protecting the Core Innovations
In today's digital age, technology and intellectual property can be significant assets for any business. During due diligence for a small business sale, buyers will evaluate the ownership, robustness, and scalability of the company's technology and IP. They want to ensure that the business has exclusive rights to its technology and that it's capable of maintaining a competitive edge in the market.
Growth Plan: Charting the Future
A well-defined growth plan is essential for buyers as they look to the future potential of the business. They will review the sales pipeline, market share, and the sustainability of the company's performance. A clear and realistic growth plan can significantly enhance the attractiveness of the business to potential buyers.
Why Founders Struggle with Due Diligence
Preparing for due diligence can be a daunting task, especially for founder-led businesses where information might be fragmented or undocumented. Critical details may exist only in the founder's head, spread across various systems, or not documented at all. This lack of structure can lead to delays and frustration for buyers, which in turn can undermine trust and potentially lead to a reduced offer for the business.
To mitigate these risks, it's vital for founders to begin organizing and documenting their business information well before a sale is on the horizon. Understanding what is due diligence and how it impacts the sale process can help founders prepare more effectively and avoid common pitfalls.
In conclusion, due diligence is not a mere checkbox exercise; it's a comprehensive investigation that buyers undertake to identify any potential risks or red flags. By understanding what buyers are looking for and proactively preparing for the due diligence process, sellers can facilitate a smoother transaction and secure a fair valuation for their business.
DIY Steps to Prepare for Due Diligence
You don’t need to wait for a buyer to start getting ready.
Here’s how to begin:
1. Start Organising Your Financials
Ensure your accounts are up to date, consistent, and easy to explain. Include 3 years of profit & loss, balance sheet, and cash flow statements.
2. Review Contracts and Legal Docs
Compile customer contracts, supplier agreements, leases, and any NDAs or IP protections. Are they valid, documented, and transferable?
3. Map Your Processes
Write down how your business actually works. From sales to fulfilment to customer service — buyers want to see structure, not improvisation.
4. Clarify Key Roles and Responsibilities
Who does what, how well, and with what oversight? A clear org chart and succession plan goes a long way in reducing buyer anxiety.
5. Check for Risks or Gaps
What would you worry about if you were buying your business? Start fixing it now, not after a buyer flags it.
