How to create a due diligence report?


Creating a due diligence report is an essential aspect to consider while evaluating deals and investments. 

In this comprehensive guide, you will explore the details of creating effective due diligence reports and find a solution that streamlines the process more than you can expect.

What is a due diligence report?

A due diligence report is a summary of the due diligence. Specifically, when companies consider partnering with a new business, their risk and compliance teams complete a due diligence process to research and uncover information. 

All their findings are then detailed in a due diligence report, including recommendations for proceeding with the business transaction (e.g., adjusting the deal structure, negotiating terms, or even canceling). 

To put it simply, every time you complete due diligence, you should also complete a report.

What is the purpose of due diligence reports?

In essence, a due diligence report is a pivotal step for investors and businesses to do the following:

  • Secure more favorable terms and pricing for a transaction
  • Detect and mitigate potential risks and liabilities
  • Comply with legal and regulatory requirements and industry standards
  • Minimize the chance  of potential disputes and litigation
  • Improve their reputation and trustworthiness among stakeholders and other key players

Before moving to a due diligence report structure, we invite you to learn more about this report to help you understand how the process works.

What does a due diligence report look like?

There is no universally accepted standard for a due diligence report format and contents. Moreover, it can vary depending on the type of due diligence you are conducting (whether it is for a merger or acquisition, a third party , or data privacy). 

However, it is advisable to review a due diligence report template examples to understand the structure and content of due diligence reports. Furthermore, analyzing a sample due diligence report may help recognize risks and opportunities associated with an investment opportunity. This way, you can target due diligence efforts toward the areas that are most likely to impact the investment success.

Who is responsible for compiling a due diligence report?

Typically, it is a company’s internal due diligence team or a paid third-party group that is responsible for writing a due diligence report. However, other internal teams should also lend their expertise to the process. 

For example, if you work on commercial due diligence, be sure to involve your marketing managers. They know better than others what to look for and how to identify potential risks.

👁️‍🗨️Pro tip: If you outsource due diligence to a third-party group, ensure that subject matter experts, legal advisors, attorneys, and company stakeholders collaborate with the outsourcing party. A balanced approach incorporating internal collaboration makes the process thorough, targeted, and aligned with the organization’s objectives of due diligence.

What is a due diligence questionnaire? 

A due diligence questionnaire, just like the due diligence report, is a way to gather information during an investigation. When you are involved in a deal, you share this questionnaire with the other party so they can answer questions that will help you write your thorough report. Based on the type of your transaction, you might also send the questionnaire to partners, potential buyers, or suppliers, with specific questions for each group.

You can find an example of a due diligence questionnaire here.

A due diligence report in 8 easy steps

Stages may vary depending on the types of due diligence reports. So, we highlight the main traditional steps and some potential challenges parties may face. Later, we will tell you how to overcome them and prepare a due diligence report that helps you make winning decisions.

1. Preliminary assessment

In the initial stage, a buyer or investor defines the objectives and aspects of due diligence. They need to review the target company’s publicly available information, such as its website, news articles, annual reports, financial statements, etc. This way, they assess its attractiveness and identify potential concerns.

Potential challenge: Identifying relevant and reliable data sources.

2. Confidentiality agreement

Parties usually sign a non-disclosure agreement to protect the confidential information of a target company. The NDA also guarantees confidentiality security for any other sensitive information that may be shared during the process.

Potential challenge: Ensuring enforcement of confidentiality provisions across all parties involved in the due diligence process.

3. Due diligence planning

An investor forms a due diligence team comprising legal professionals, financial advisors, operational specialists, and industry experts. They create a due diligence request list outlining the information they need for a due diligence review. This due diligence checklist may include contracts, financial statements, employee records, and intellectual property documents.

👁️‍🗨️Tip: You can download a free due diligence checklist template online and see what to include in a due diligence report.

Potential challenge: Coordinating schedules and availability of diverse experts and stakeholders for the due diligence team.

4. Document reviews

When the company being evaluated provides the requested documents, the buyer’s team will review each due diligence document in detail. This team may also visit the target company’s facilities to examine its operations, manufacturing processes, and other activities. Thus, the buyer can better understand the target’s inventory, assets, and operations. 

The buyer’s team may also talk with key employees, management, clients, and stakeholders. It is a way to learn about the company’s reputation, strategies, culture, relationships, and challenges.

Depending on the nature of the business, this process may be essential for the buyer to make an informed decision.

Potential challenge: Managing the volume of documents effectively and verifying the authenticity and completeness of provided data.

5. Analysis, validation, and risk assessment

This step involves evaluating various aspects of the target company, validating the accuracy and reliability of the obtained information, analyzing the company’s valuation, and identifying potential risks associated with the acquisition. It is an iterative process that involves cross-referencing data from different sources to comprehensively and precisely understand the target company operation.

Potential challenge: Overcoming potential resistance or reluctance from the target company to provide access to sensitive information.

6. Documentation and report preparation

After assessing risks, a due diligence team creates a report highlighting key risks, opportunities, and recommendations. The report also includes contracts, financial records, and all other evidence supporting the findings.

Potential challenge: Ensuring accuracy and reliability of data obtained from various sources.

7. Decision-making and negotiation

A buyer or investor carefully evaluates the due diligence report to make an informed decision about the deal. Sometimes, they may opt to negotiate the purchase price or other terms. If due diligence uncovers issues, they withdraw from the deal.

Potential challenge: Compiling and organizing findings from various sources into a coherent report.

8. Deal closing

When both parties agree on the terms, they finalize the legal agreements and close the transaction.

Remember the following points while creating your report:

  1. Consistent format. Use a uniform format in the report to aid readability and enable easy data comparison. A standardized structure helps the reader navigate seamlessly and focus on the content instead of being distracted by changing layouts.
  2. Clear language. Good reports use clear and straightforward language to make the content accessible to all readers, regardless of their expertise.
  3. Visual aids. Visual aids like graphs, charts, and tables can improve data presentation by making it easier to understand large amounts of information quickly.
  4. Explanations. Not everyone may be familiar with industry-specific language. To make your report accessible to a broader audience, including those without technical backgrounds, it’s a good idea to explain unfamiliar terms in simple language. This way, nobody feels excluded.
  5. Well-organized executive summary. An executive summary is usually the first part of a report that readers engage with. Therefore, it should be well-structured and accurately summarize findings.
