The increasing corporate expenditure on auditing and recording is expected to drive the growth of the financial auditing professional services market in the coming years. Corporate auditing and recording encompass costs incurred by companies for external audits, internal control evaluations, and other financial-reporting processes required by regulators and stakeholders. The rise in spending on auditing and recording is driven by stricter regulatory requirements and the growing demand for transparent financial disclosure. Financial auditing services address these needs by offering independent verification of financial statements, helping companies adhere to regulations, improve transparency, and mitigate risk. For example, in January 2025, according to the Financial Education & Research Foundation (FERF), a US-based nonprofit affiliated with Financial Executives International (FEI), average audit fees paid by public companies rose from USD 2.83 million in 2022 to USD 3.01 million in 2023, representing a 6.4% increase. As a result, the growing corporate investment in auditing and recording is fueling the expansion of the financial auditing professional services market.

For example, in July 2024, KPMG, a Netherlands-based professional services firm offering audit, tax, and advisory services, launched the upgraded KPMG Clara platform, a generative AI-powered audit solution aimed at optimizing audit workflows, supporting risk evaluation, and enhancing documentation accuracy, with features including automated query management, real-time analytical insights, and AI-assisted workpaper support.
