Top Auditing Services Companies

Deloitte, PwC, EY, and KPMG (the so-called Big Four) dominate the global market for auditing services. These firms are repositioning themselves for continued dominance through strategic acquisitions and technology investments. For instance, Deloitte acquired CeleritiFinTech for the purpose of bolstering its digital auditing service, especially in financial services. With similar intent, PwC has invested in AI-aided audit tools to make the work process faster and provide insights quicker and with greater accuracy. All of these strategies ensure that these companies remain competitive with efficient services, and they are also increasing their footprints in emerging markets like Asia-Pacific and Africa, which are witnessing rapidly growing demand for auditing.

Smaller companies are also finding niches for themselves with specialized strategies. Local players provide tailored, industry-specific audits to meet local market requirements. For example, BDO and Grant Thornton aim at mid-market firms with cost-effective, tailored auditing solutions, drawing on their local regulatory expertise. On their part, an increasing demand for ESG audits has prompted such firms to spend money on sustainability and CSR audits, further establishing themselves in an increasingly sustainability-sensitive market. All this serves to assist regional firms in retaining and expanding their clients through the addition of value over and above mere financial audits.
