The “Big Four” accounting firms are Deloitte, PricewaterhouseCoopers (PwC), Ernst & Young (EY) and KPMG. They offer such services as audit, assurance, corporate finance and legal services, among others. Deloitte was the largest of the four companies and therefore the largest in the world in terms of revenue in 2018. With a revenue of 41.28 billion U.S. dollars, PwC was not far behind the 43.2 billion generated by Deloitte.
