What Is Due Diligence? Process and Significance in a Company Sale
Due diligence is the careful examination of a company by the buyer. What is reviewed, how it works, and how sellers prepare.
At the latest when a buyer shows serious interest, the term comes up: due diligence. It refers to the careful examination of the company by the prospective buyer before they finally commit. For sellers it is one of the decisive phases — for here it is decided whether trust arises or doubt.
What does due diligence mean?
"Due diligence" means, literally, the required care. The buyer examines the company systematically in order to understand opportunities and risks, secure the purchase price and avoid later surprises. It usually takes place after the letter of intent (LOI), in a protected data room in which the seller provides the documents.
Which areas are examined?
Depending on the company the scope varies; typically the review covers:
-
Financial due diligence: annual accounts, planning, earnings and liquidity, quality of the figures.
-
Legal due diligence: contracts, corporate structure, litigation, permits.
-
Tax due diligence: the tax situation and risks.
-
Commercial due diligence: market, competition, customer and supplier dependencies.
-
Depending on the sector, additionally technical, HR or IT reviews.
Vendor due diligence — the examination before the examination
Some sellers have their own company examined in advance (vendor due diligence). This uncovers weaknesses early, so that they can be remedied or explained before the buyer finds them — a means of protecting value.
How do you prepare as a seller?
The best due diligence is the one that brings no surprises. Helpful are: clean, transparent figures and an orderly data room; openness about known weaknesses — explaining them builds more trust than concealing them; reduced dependence on the owner and on individual customers. Whoever prepares early gets through the review faster and more securely — and avoids subsequent price reductions.
