Due diligence is the phase of a business acquisition that often generates the most anxiety for sellers. After weeks or months of conversations, a letter of intent has been signed, and now the buyer is going to look under the hood. For many business owners, this feels like an audit, an examination that might uncover something disqualifying. In reality, due diligence is simply the process by which a buyer confirms that the business they are acquiring matches what they have been told. It is a normal, necessary, and ultimately healthy part of any well-structured transaction.
Understanding what buyers look for during due diligence, and preparing for it in advance, can make the difference between a smooth process and one that stalls or falls apart. Here is a detailed look at the major areas of due diligence and what you can do to be ready.
What Due Diligence Actually Is
At its core, due diligence is a verification process. The buyer has formed a thesis about your business based on initial conversations, financial summaries, and their own research. During due diligence, they test that thesis against detailed data and documentation. They are looking for confirmation, but they are also looking for risks, things that could affect the value of the business or the structure of the deal.
For most small and mid-sized business sales in the Seattle area, due diligence typically takes between 30 and 60 days. During this period, the buyer will request a wide range of documents, ask questions, possibly visit your facilities, and may speak with key employees or customers, usually with your permission and under confidentiality agreements.
The depth and formality of due diligence can vary significantly depending on the buyer. A private equity firm will typically have a more structured and intensive process than a holding company or individual buyer. Regardless of the buyer's approach, being prepared and responsive will keep the process on track and demonstrate professionalism.
Financial Due Diligence
Financial due diligence is almost always the most intensive area of review. Buyers need to understand the true earnings of the business, the quality of those earnings, and the financial trends that will shape future performance.
At a minimum, expect a buyer to request the following:
- Three years of financial statements including profit and loss statements, balance sheets, and cash flow statements. If your financials are prepared by a CPA or reviewed by an outside accounting firm, that adds credibility.
- Three years of tax returns including federal, state, and any applicable local filings. Buyers will compare your tax returns to your financial statements to identify discrepancies.
- Accounts receivable aging reports showing how much is owed to the business and how long those receivables have been outstanding. High concentrations of overdue accounts can be a red flag.
- Accounts payable schedules to understand the business's outstanding obligations and payment patterns.
- Revenue breakdowns by customer, product line, or service category. Buyers want to see where the money comes from and how diversified those sources are.
- Add-back schedules documenting any owner-related or one-time expenses that should be adjusted to reflect the true earning power of the business.
The goal of financial due diligence is not to find problems but to confirm earnings and understand the financial trajectory of the business. Clean, well-organized financial records are the single most important thing you can provide.
Operational Due Diligence
Beyond the numbers, buyers want to understand how the business actually works day to day. Operational due diligence examines the processes, systems, and people that generate the results reflected in the financials.
Processes and Systems
Buyers will want to understand your core operational workflows. How are orders taken, fulfilled, and invoiced? What technology systems do you use? Are processes documented, or do they exist only in people's heads? A business with well-documented standard operating procedures is easier to transition, easier to manage, and ultimately more valuable. If you operate in industries common to the Puget Sound region, such as distribution, construction services, or manufacturing, operational efficiency is especially critical to valuation.
Key Person Dependencies
One of the most important questions a buyer will ask is: what happens if the owner leaves? If the business depends heavily on one or two individuals, including the owner, that represents a significant risk. Buyers will assess whether there is a capable management team in place, whether employees are cross-trained, and whether customer relationships are held by the company or by specific people. Reducing key person dependencies before going to market is one of the highest-impact things a seller can do.
Technology and Infrastructure
Buyers will evaluate the technology stack, physical assets, and infrastructure that support the business. Are equipment and facilities well-maintained? Is the technology current, or will significant investment be required after the acquisition? For businesses in the Seattle area, where technology adoption tends to be higher than the national average, outdated systems can be a particularly notable concern.
Legal Due Diligence
Legal due diligence covers the contracts, intellectual property, compliance obligations, and potential liabilities associated with the business. Buyers are looking for anything that could create a legal or financial exposure after the acquisition closes.
Contracts and Agreements
Expect buyers to review all material contracts, including customer agreements, vendor contracts, leases, employment agreements, and any non-compete or non-disclosure arrangements. They will pay particular attention to change-of-control provisions, meaning clauses that allow the other party to terminate or renegotiate the contract if the business is sold. If your lease or a major customer contract has such a provision, it is important to identify it early and plan accordingly.
Intellectual Property
If your business has trademarks, patents, copyrights, trade secrets, or proprietary technology, the buyer will want to verify ownership and assess the value and protections in place. For service businesses, this may include proprietary processes, methodologies, or software that differentiate your offering in the market.
Compliance and Litigation
Buyers will ask about any current or pending litigation, regulatory investigations, or compliance issues. In Washington state, this includes matters related to employment law, environmental regulations, and industry-specific licensing requirements. A clean compliance record is reassuring; outstanding issues need to be disclosed early and addressed transparently.
Customer Due Diligence
The value of your business is ultimately driven by your customers, and buyers will examine your customer base carefully.
Customer Concentration
If a single customer represents more than 15 to 20 percent of your revenue, that is a concentration risk. Buyers will want to understand the relationship, the contractual arrangements, and the likelihood of retention after the sale. High customer concentration does not necessarily kill a deal, but it will affect valuation and may influence deal structure.
Retention and Satisfaction
Recurring revenue and high customer retention rates are among the most valued characteristics in any business. Buyers will look at customer turnover, the length of customer relationships, and any available data on customer satisfaction. In the relationship-driven business community of the Pacific Northwest, long-standing customer relationships are often a significant source of value.
Revenue Quality
Not all revenue is created equal. Recurring, contracted revenue is more valuable than one-time project revenue. Revenue from a diversified base is more valuable than revenue concentrated in a few accounts. Buyers will assess the quality and sustainability of your revenue streams as part of their overall evaluation.
How to Prepare for Due Diligence
The sellers who navigate due diligence most successfully are the ones who start preparing long before a buyer is at the table. Here are practical steps you can take.
- Organize your documents early. Create a virtual data room with all the financial, legal, operational, and customer documentation a buyer is likely to request. Having everything organized and accessible shows professionalism and keeps the process moving.
- Clean up your financials. Work with your CPA to ensure your books are accurate, current, and clearly presented. Prepare add-back schedules and be ready to explain any unusual items.
- Document your processes. Write down the standard operating procedures for key business functions. This does not need to be a thousand-page manual, just clear documentation of how things work.
- Review your contracts. Read through your major contracts and identify any change-of-control provisions, expiration dates, or unfavorable terms that might concern a buyer.
- Address known issues. If you know there are problems, whether it is a pending compliance matter, a key employee who is about to leave, or aging equipment that needs replacement, address them before due diligence begins. It is always better to fix an issue than to explain it.
- Be honest and forthcoming. The worst thing a seller can do is hide or minimize an issue that the buyer will eventually discover. Transparency builds trust, and trust is the foundation of a successful transaction.
The Goal Is a Smooth Transaction
Due diligence can feel intrusive, but it serves an important purpose for both parties. For the buyer, it provides confidence that they are making a sound investment. For the seller, it validates the value they have built and sets the stage for a clean closing. When both sides approach the process in good faith, with preparation and transparency, the outcome is almost always positive.
