Business transactions today are far more complex than simple balance sheet reviews. Mergers, acquisitions, private equity investments, and strategic partnerships involve multiple stakeholders, regulatory scrutiny, and long-term financial commitments. In such an environment, assumptions can be costly.
Both buyers and sellers need clarity on financial health, sustainability, and risks before entering a deal. A transaction built on incomplete or misunderstood financial information often leads to valuation disputes, delayed closures, or post-deal surprises.
This is where financial due diligence plays a critical role. However, the approach differs depending on whether the party is acquiring or selling the business. Buy-side and sell-side financial due diligence serve different objectives, timelines, and risk perspectives, making them two distinct but equally important processes.

Key focus areas include:
Buyers use the findings from due diligence advisory exercises to negotiate pricing, adjust deal terms, or restructure transaction models. The goal is not only to uncover risks but also to understand whether the investment thesis remains valid.
Sell-side financial due diligence is initiated by the seller to prepare the business for scrutiny by potential investors or buyers. Instead of reacting to buyer queries, sellers proactively assess their own financial position.
