What is acquisition due diligence?
Short Answer
Acquisition due diligence is the structured verification of what you are buying — financial, legal, commercial, tax, people and, crucially, the intangible assets that make up most of the value — before you commit.
Full Explanation
Acquisition due diligence is how a buyer confirms that the business they are paying for is what it appears to be.
It runs across several workstreams. Financial diligence tests the quality of earnings, working capital and debt. Legal diligence examines contracts, disputes, ownership and change-of-control clauses that could be triggered by the sale. Commercial diligence assesses the market, customers and concentration. Tax, and people and HR diligence, cover their own risks. And because most of a modern business's value is intangible, intangible-asset diligence — organised around Opagio 12 — asks whether the brand transfers, whether the technology and IP are owned with clean title, who the key people are, and what walks away on completion.
Findings do not just kill or confirm deals; they reshape them, feeding into the price, the earn-out, and the warranties and indemnities a seller must give. Good diligence is a hunt for the intangible value you are paying for and the risks hiding beneath the accounts.
