Global Accounting Services Industry Data and Analysis
Global accounting companies continue to benefit from robust demand across core markets, as the need for quality and efficient accounting services persists. Economic expansion in developed countries and high productivity growth in low-income nations fueled world GDP growth. Increasing M&A activity, particularly in developing markets such as the Middle East and Asia, broadened the scope of demand for accounting services ranging from consulting to auditing. However, elevated interest rates, which spiked in 2023 in response to high inflation across the globe, curtailed smaller clients’ capability of procuring external accountants and drove higher demand for DIY solutions. Nonetheless, the mandatory nature of the accounting space and the prevalence of the Big 4 in relation to complex auditing and tax preparation tasks continued generating robust global revenue in core North American and European markets. Revenue grew at a CAGR of 3.1% to an estimated $643.8 billion over the past five years, including an estimated 4.8% spike in 2025 alone.
