Acquisition audit: what it really does and how to use it

Updated March 2026 - An acquisition audit — also called due diligence — is a decision-support tool used before a business purchase or an external growth operation. Its purpose is to test the reliability of the information provided by the seller, identify the risk areas that need to be priced or protected against, and frame the basis for price negotiation and warranty coverage.

A well-structured due diligence covers four main areas:

• ▸financial quality: are the reported results sustainable? Do the accounts reflect the real economic performance of the business, or have they been presented in the most favourable light? This includes reviewing margins, working capital dynamics, off-balance-sheet items and non-recurring elements;
• ▸tax and social risks: are there open tax positions, pending adjustments, undeclared social charges or employee classification issues that could create future liabilities for the buyer?
• ▸legal and contractual matters: are there contracts, commitments, litigation or intellectual property issues that affect the value or continuity of the business?
• ▸business model sustainability: does the business model hold up under scrutiny — is the customer base concentrated, are key contracts secured beyond the transaction, and is the operational model genuinely scalable?

The acquisition audit can reveal four types of finding that directly affect the transaction:

• ▸a gap between the narrative and the reality: revenues that are not as recurring as presented, costs that are understated, or cash dynamics that look better than they are;
• ▸risks that must be factored into the price: tax provisions, potential employment litigation, environmental liabilities or underfunded pension obligations;
• ▸warranties that need to be requested: specific representations and warranties to cover identified risks that cannot be fully quantified before closing;
• ▸post-acquisition work that must be budgeted: integration tasks, compliance catch-up or restructuring that will consume management time and cash in the months after closing.

Hayot Expertise advice: a good acquisition audit does not aim to kill the transaction. It aims to understand it better, price it more accurately and secure it more effectively. The buyer who enters a transaction without due diligence is taking on risks they have not measured — and cannot manage.

We recommend structuring the audit output around four practical uses:

1. ▸the price: which findings justify an adjustment to the offer price or earn-out structure?
2. ▸the warranties: which specific representations and warranties should be required to cover identified risks?
3. ▸the first 100-day plan: which operational, compliance or governance actions must be taken immediately after closing?
4. ▸integration capacity: is the acquiring organisation actually ready to absorb the target — from IT systems to management bandwidth to cultural fit?

We can help you read the risks, the numbers and the integration priorities before you commit.
