Commercial Due Diligence: Explanation, Checklist

Commercial due diligence forms an important building block in the examination of a company before and during a transaction, analyses the market and in particular the value chain of the business model and answers the question of its sustainability.

The main points of a commercial due diligence investigation are:

  • Business model
  • Market position
  • Strategy

In contrast to the other types of due diligence, commercial due diligence is primarily interested in the future development of the target company and its market environment. 

Based on a comprehensive and in-depth detailed analysis of the market and competitive environment as well as the customer portfolio, the business planning and in particular the planning assumptions made are validated. 

The focus of interest is the question of how secure and resilient the current customer relationships are and what future growth potential there is with existing customers and new customers. The greatest customer-side risk is always the loss of a major customer after the transaction. 

One of the core tasks of commercial due diligence is to conduct expert interviews in the market with e.g. suppliers, trading partners, competitors and customers to determine the perception and positioning of the target company in the market. 

Sometimes the terms strategic due diligence, customer due diligence or market due diligence are used instead of commercial due diligence. The term commercial due diligence is the most common.

Private equity commercial due diligence

Commercial due diligence reports are usually commissioned by private equity companies. They are rarely commissioned by strategic buyers. 

Private equity is private equity capital provided by banks, insurance companies, pension funds and other institutional investors. This capital is used to acquire stakes (especially majority stakes) in companies. The return on investment (ROI) depends on the increase in value of the target company throughout the investment. 

To achieve a high ROI, investments are made selectively after comprehensive prior due diligence. The increase in value is usually achieved through organic company growth, by pursuing a “buy and build” strategy or through targeted restructuring measures. 

The holding period is usually three to seven years but depends on the performance of the target company. 

Depending on the size of the target company, the divestment (exit) takes place either through a sale to a strategic investor (trade sale), to another financial investor (secondary buy-out), an IPO (initial public offering) or, in rare cases, to the existing shareholders (buy-back). 

For the fundraising, the investments and the management of the holdings, private equity companies receive an annual management fee, which is usually around 2-3% of the fund volume. In addition, private equity companies are remunerated through profit sharing.

The financing of an investment is often realised in the form of a “leveraged buy-out” (LBO). In this form of financing, a significant share of the transaction volume is covered by debt capital, whereby private equity companies use the debt financing share as leverage to increase the return on equity in the course of the investment.


Many of these questions can only be answered in discussions with those responsible at the target company. Often, therefore, extensive interviews will have to be conducted as part of the commercial due diligence.

This is the only way to make meaningful strengths, weaknesses, opportunities and threats analysis for the company and to determine what effects various scenarios will have on the future development of the company.

The findings from the commercial due diligence are transferred to the planning calculations and thus form the basis for the company valuation.

At this point, the commercial due diligence transitions into financial due diligence.
