Due diligence should investigate the uncertainties that could change a purchase decision or its terms. Start by defining what is being acquired: shares, selected assets or another transaction structure. That choice affects the questions and evidence needed. A generic checklist can be a starting aid, but it should not substitute for understanding the business model, the proposed deal and the buyer's reasons for proceeding.
Agree the commercial objective, timetable and information available. Identify the principal risks: quality of earnings, debt, working capital, tax, contracts, staff, property or licences may matter differently in each transaction. Financial work should be coordinated with legal and other specialist reviews. A financial adviser cannot resolve every legal or technical question merely because it appears in a document stored in the same data room as the accounts.
Define deliverables and materiality in practical terms. The report should distinguish findings, estimates, assumptions and questions that could not be answered. Specify the periods examined and how information will be reconciled to accounts and source records. An existing audit report may provide context, but acquisition diligence has a different purpose and scope. It should not be described as guaranteeing that the target has no undiscovered liabilities or operational weaknesses.
Consider a hypothetical buyer acquiring a regional maintenance business. Recurring customer contracts and technician availability may be central to value, while a large unexplained receivable could affect cash expectations. The scope prioritises those areas alongside the proposed transaction structure. It does not spend equal effort on every balance simply because a standard template lists them in the same order or because some documents are easier to obtain than others.
Use a request list that links documents to questions. Accounts, ledgers, contracts and tax records should support analysis rather than accumulate without a defined purpose. Keep a questions log and record limitations on access. Where the seller provides only summaries, explain what verification remains impossible. The buyer can then decide whether to seek more evidence, alter terms or obtain separate specialist work before making a commitment.
Finish with an agreed scope note and a process for escalating significant findings. Discuss how results may affect pricing, conditions, warranties or further review with the relevant advisers. An initial diligence scoping session can focus effort on decision relevant uncertainties, allowing the buyer to commission appropriate work while recognising the limits of any review performed on the information made available.
