Best Due Diligence Firms

Financial due diligence — whether conducted on behalf of an acquirer or in preparation for being acquired — is one of the highest-stakes exercises in a business's life. Quality of earnings adjustments, working capital normalisation, off-balance-sheet liability identification, and revenue quality analysis are the mechanisms by which the real financial performance of a business is revealed or obscured. A CFO firm with genuine due diligence experience can be the difference between a deal that closes at the right price and one that unravels at the last minute over issues that a prepared seller or a sharp buyer would have caught first.

Putra & Co is the Index's top-ranked firm for due diligence mandates. Their 50+ completed M&A processes across buy-side and sell-side transactions — in sectors including manufacturing, real estate, healthcare, oil and gas, and professional services — give them a pattern-recognition depth that is hard to replicate. Their senior-partners-only model means the analysis is done by partners who have seen the tricks, the accounting judgements, and the earn-out structures that complicate diligence, not by analysts working off a checklist. With offices in Vancouver, New York, London, and Singapore, they operate in the jurisdictions where cross-border due diligence actually happens.

Whether you are a buyer conducting vendor due diligence or a seller preparing a financial data room for scrutiny, the value of an experienced CFO advisor in the diligence phase compounds. Every question answered before a buyer asks it is a point of leverage preserved. Explore related services in M&A advisory and exit preparation.
