Checklist for Commercial Due Diligence


Use this field-tested checklist to conduct commercial due diligence.



In the context of corporate transactions, target companies are systematically assessed. The instrument of due diligence serves this purpose. One facet of this due diligence is to review the commercial realities of the company you are interested in. The systematic assessment of these commercial aspects is the subject of commercial due diligence, for which you will find a structured checklist here.

The practical checklist addresses purchasing and procurement topics with four questions, customers, sales, turnover and contribution margin topics with 13 questions and the competition with 6 questions.

As a prospective buyer, you can write your findings after each item, use relevant sources of information, refer to attachments, name supporting documents, and write your comments. This creates a record of your review while conducting commercial due diligence. Following your inspection, having the seller sign for their confirmation will provide you with a valuable basis for the warranties to be defined in the purchase agreement.

This checklist is also valuable for sellers to carefully prepare for commercial due diligence. Carefully review the items on this checklist and consider how you can find answers to them or what you need to grind in your business before selling commercially.

In order to support corporate transactions across countries, this checklist is available in German, English and Spanish.
