In the world of business, companies are constantly buying, selling and merging with each other, all which fall under the heading of mergers and acquisitions (M&As). One of the standard terms that is an important part of the M&A lexicon is “due diligence,” which is something that occurs in virtually every transaction. Knowing what due diligence is, the various types of it, and how it’s used is vital for every party involved in any sort of M&A (or other type of business) transaction.


About Due Diligence

Due diligence is a necessary, often intense process that involves an investigation, audit and a review to shore up assumptions and gather all the necessary details leading up to the closing of a business deal. The endgame of due diligence is ascertaining all the facts, figures and other details that are part of the transaction. It typically involves a deep dive into the financial, legal and corporate records of the company that you’re doing business with.


The Purpose of Due Diligence — What Does It Entail?

Performing due diligence is far more intense than simply going over the balance sheets and tax records of a company. Of course, that information is mandatory, but there’s so much more to scrutinize. A meaningful due diligence round involves the following information.


  • Revenue, profit and margin trends: Of course, these are a major component of any company that you’re looking to do any sort of transaction with. Confirming that these numbers are accurate and that there are no jokers in the deck is important.  
  • Valuation multiples: There are several types of financial metrics used when conducting a business deal, but there is no better way to get to the bottom of the fiscal health of a company than knowing the valuation metrics, which includes earnings per share (EPS), price-to-earnings (P/E) ratio, price-to-book (P/B) ratio and price/earnings growth (PEG) ratio, among other metrics.
  • Industry and competition: It’s not only a matter of investigating the company that you’re working with in the transaction. Due diligence also requires a more holistic view of the entire industry that examines how the company in question stacks up against its peers in the industry. Learning about the entire industry as a whole will shed light on the company you’re dealing with.
  • Management and share ownership: This is about the structure of the company — the founders and other officers. Knowing how long these people have been on board, how many shares they hold and how (and when) there have been shares sold in the past is critical. 
  • More issues and concerns: Of course, there are scores of other issues, facts and figures and other factors that must be examined. These include stock info (history, possible dilution), risks (both long- and short-term) and any other factors that could impact either the company itself, its industry or the overall economy.


13 Types of Due Diligence in Business

Just as there are many types of businesses and business transactions, there are also multiple flavors of due diligence, some not even listed here. As you will see, all of them overlap (to some degree) with others in the list. They include the following:


1. Merger and acquisition due diligence

One of the most common types of due diligence deals with M&As, and this encompasses many of the areas in the other items on this list. These include financial items (earnings and profits, sales and revenues), human capital and technology, among many others.


2. Financial due diligence

Naturally, this is one of the big ones. It includes all the company’s financial statements, tax filings, capital expenditures and audits, among many other factors. Financial due diligence encompasses many details, including analysis of customer accounts, fixed and variable cost analysis and other projections.


3. Legal due diligence

A review of all things legal, which includes minutes of both board meetings and shareholder meetings, details about shares issued to leadership and all contracts, which include joint venture and partnership agreements, LLC or other operating agreements and licensing and franchise agreements. 


4. Customer due diligence

Because customers are a critical part of a company’s lifeline, due diligence into the customer base is required, along with looking at who the top customers are, any pending service agreements and/or insurance coverage and all other customer data.


5. Administrative due diligence

This involves verifying administrative-related details of a company. It includes all disparate facilities, occupancy rate, workstations and other important admin data. It ties in with the financials, as these costs are closely connected to the financial aspect of the process. 


6. Environmental due diligence

This is examining regulations and is important because violations in the environmental area can be extremely costly. It includes environment permits and licenses, proof of compliance with all current regulations and any current contingent environmental liabilities.


7. Human resource due diligence

Like financial due diligence, HR due diligence is quite extensive, and it includes the analysis of current positions and vacancies, details about future attrition, examining the contracts that involve HR, all benefit and retirement packages and policies that are part of the human resources department.  


8. Asset due diligence

This includes details on fixed assets, lease agreements, real estate details (deeds, mortgages, title policies and use permits) and schedules of sales and purchases of major capital equipment over the past several years.


9. Intellectual property (IP) due diligence

IP due diligence includes a deep dive into schedules of patents (and patent applications), copyrights, trademarks, trade secrets and brand names, as well as any pending legal actions involving the company’s IP licenses.


10. Commercial real estate due diligence

This entails examining purchase and sales agreements, contracts and leases related to the target company, any partnership agreements (past, present and future) and purchase and sales of foreclosure properties and real estate portfolios.  


11. Operational due diligence

Typically performed by the acquiring company, venture capitalists and private equity firms, operational due diligence (ODD) examines the operational risks and processes that can potentially lead to growth.


12. Technical due diligence

This is a deep dive into the technical aspects of a company, which may encompass the entire organization (such as its products and services, in the case of tech firms), or the technical aspects of other types of companies (including architecture, web infrastructure, databases, security and other issues).


13. Commercial due diligence

Commercial due diligence investigates the target company’s products and/or services, along with its operations and history. This includes management structure, any legal issues, its sales and marketing, its competition and its industry as a whole.
