Auditing Services Market Size (2022 - 2027)

The global market for auditing services, which was assessed to be worth US$217.7 billion in 2021, is anticipated to grow to US$287.2 billion by 2026, with a CAGR of 4% between 2021 and 2026.

Over the projected period, the global auditing services market is expected to rise due to increasingly authoritarian government rules surrounding financial disclosure and reporting. In addition, one of the significant trends in the Auditing Services Market has been market consolidation. As a result, many auditing firms have been purchased by major accounting firms to expand their service line or strengthen their existing auditing services.

Auditing is described as the assessment of the accuracy and dependability of financial and non-financial data, as well as the systems and processes that record and summarise such data. Audit firms provide integrated, strategic, and enlarged audit reports to address concerns and opportunities that affect a company's long-term worth.

Auditing services are independent reporting procedures that objectively evaluate a company's financial records and other financial activities to satisfy regulators, investors, directors, and managers that the financial statements are accurate. 

Shared service delivery models may enable audit firms to collaborate with companies specializing in digital technologies such as big data, analytics, machine learning, mobile computing, and business intelligence. Data analytics services are poised to emerge as new sources of revenue generation that can supplement auditing firms' core business.
