Auditing Services Market

Global Auditing Services Market Size (2024 to 2032)

The global auditing services market is estimated to be worth USD 312.75 billion by 2032 from USD 226.6 billion in 2024, growing at a CAGR of 4.11% from 2024 to 2029.

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.

Current Scenario of the Global Auditing Services Market

In recent times, the auditing services market witnessed a burst of acquisitions and mergers. Mid-range such as Baker Tilly and Grant Thornton have sold controlling holdings to private equity, and other prominent players in the market are engaged in extending their footprints. Like, earlier in 2024, CBIZ picked up stakes in Brown & Kloster LLC, and CompuData and Erickson, and on the other hand, Marcum bought Croskey Lanni PC and others. It's evident that companies and organisations are working diligently to enhance their offerings and compete with the Big Four, comprising PwC, KPMG, EY, and Deloitte. In addition, today's market players are offering a wide range of services from accounting and tax to specialized services such as executive search and technology solutions to gain a competitive edge over their counterparts. When examining the overall landscape, the accounting profession is experiencing a substantial evolution. Market consolidation, regulatory burdens, and technological breakthroughs are propelling shifts throughout the market. Additionally, investments in digital transformation and innovations are heart of the market’s future, with a particular focus on high-growth areas like virtual risk and ESG advisory services.

Over the forecast period, the global auditing services market is expected to rise due to increasingly authoritarian government rules surrounding financial disclosure and reporting. In addition, one significant trend 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 lines or strengthen their existing auditing services.

MARKET DRIVERS

The growing corporate spending on financial audits and recording encourages new entrants to choose auditing services is one of the major factors propelling the auditing services market expansion.

Furthermore, rising demand for auditing services across various industries, such as healthcare, IT & telecommunications, BFSI, and others, to manage businesses' workflow is likely to fuel the expansion of the auditing services market throughout the forecast period. Technological advancements in audit services to assist auditors in gaining actionable insights by leveraging financial numbers and graphs from organizations are supporting the growth of the auditing services market.

Rising demand for financial transparency propels the market growth. Given the situation of the global economy and the volatile financial market worldwide, there is an escalating demand for financial transparency. The changing technological landscape and the application of new business models have increased irregularities in digital finance.

• According to Consumer International, about 43 per cent of customer bodies found the absence of transparency as a major issue in digital finance. As per their 6 months campaign regarding Transparent Digital Finance for Consumers, outcomes reveal that transparency goes beyond simply fulfilling regulatory obligations.

MARKET RESTRAINTS

Limited awareness about financial auditing services among people is a significant issue projected to limit the global market's growth over the forecast period. Furthermore, another factor launched to impede the development of the auditing services market over the forecast period is an increase in people's inclination for automation or artificial intelligence (AI) across various industries.

MARKET OPPORTUNITIES

The adoption of AI-powered innovations is expected to shape the future of the auditing services market. The specific manners in which auditors are currently utilising AI continue to be largely undiscovered. It is predicted that AI will be employed in real-time auditing to perform 24/7, examining vast amounts of data for trends and anomalies, finding unusual transactions, evaluating the stability of a company and forecasting its future viability.

• According to the survey of the Center for Audit Quality, 1/3^rd of public entities are utilizing artificial intelligence in their financial reporting. However, it is believed to elevate in the coming years.
• As per another survey published in Thomson Reuters, 8 per cent of tax companies were found to be using Generative AI technology, with 13 per cent of establishments preparing to employ this technology soon.

In 2023, artificial intelligence has become a fundamental component of workflows for accounting and tax professional’s processes by optimizing activities, improving precision, and allowing experts to concentrate on higher-value jobs.

MARKET CHALLENGES

The expansion of the auditing services market is impeded by the reluctance to use artificial intelligence. It is set to reshape the market in future, but currently, its adoption is difficult due to several factors including the absence of infrastructure and training, highly costly technology, difficulty in usage, etc.

• According to the Journal of Accountancy, major reasons stated by companies for not integrating AI technology into their organization and audits are the lack of training and infrastructure (23 per cent of survey participants), technology is extremely expensive (17 per cent), not useful technology (17 per cent), incompetent to access usable customer data (13 per cent), and insufficient client controls for data integrity (4 per cent)

Risk of employing AI in auditing is another factor impeding the market growth. Basically, there is still a dependence on the accurate data being entered at the outset. Similarly, AI cannot determine if an answer or solution has been implemented appropriately. Besides being faster than humans, the risk equally persists due to the absence of transparency in reaching results or outcomes.

• As per the findings of a survey by the KPMG, about 65 per cent i.e. 2/3^rd of firms are turning to their external auditors for assistance with AI-related threats and problems, particularly through extensive evaluations of their AI control frameworks.
