What Buyers Actually Check in Due Diligence

24 April 2026 · 7 min read

Price is agreed on the strength of your story. It is kept, or lost, on the strength of your evidence.

Financial due diligence

  • Three years of financial statements and tax returns, reconciled to the ledger
  • Quality of earnings: are the add-backs real and recurring?
  • Revenue by customer, by month, with churn and renewal data
  • Gross margin by product, service line or site
  • Working capital by month, to set a normal level for completion
  • Capital expenditure history versus depreciation

Legal and contractual

  • Customer and supplier contracts, especially change-of-control clauses
  • Property leases, options and make-good obligations
  • Employment agreements, entitlements and any underpayment exposure
  • Intellectual property ownership — including work by contractors
  • Litigation, disputes and regulatory correspondence

Operational

  • Documented processes and system access
  • Key person risk and staff retention plans
  • Condition and remaining life of plant and equipment
  • Data, cyber and privacy practices

The findings that reprice deals

In practice a handful of issues account for most price reductions: add-backs that cannot be evidenced, employee entitlements that were never provisioned, a top customer with no contract, unbilled or overstated work in progress, and stock that has not moved in a year still carried at cost.

How to prepare

Run diligence on yourself first. Assemble the data room before you have a buyer, have your accountant test the add-backs, and write a short explanation for every unusual line in the accounts. A seller who answers on the same day keeps momentum, and momentum keeps price.
