Largest consulting firms with an audit and accounting heritage

South America is home to thousands of large, mid-sized, small and boutique audit and accounting firms, most of which today also provide a range of advisory and consulting services. 

Latin America’s consulting industry is valued at around $5.1 billion, one fifth of the size of the Asia Pacific market, but still significantly larger than the consulting markets of the Middle East ($3.6 billion) and Africa ($2.9 billion). Not surprisingly, Brazil is Latin America’s largest consulting market, making up almost half of the total by value. 

A growing share of the South America’s consulting market is being held by firms which traditionally focused on the audit and accounting space. In sync with a global trend, audit and accounting firms in the region have been branching out their areas of expertise to include advisory services, enabling them to tap into unregulated and more lucrative areas of work (consulting fees are typically higher than accounting fees) while positioning them to better serve their clients with a more end-to-end portfolio of offerings.

Largest consulting firms with an audit and accounting heritage

Probably best illustrating accounting’s push into consulting are the Big Four firms of Deloitte, EY (formerly Ernst & Young), KPMG and PwC. A decade ago, the quartet generated over forty percent of their revenues with audit and accounting services. Today, the situation has reversed, and over half of their fees comes from consulting and other advisory services such as mergers & acquisitions, restructuring and digital transformation. 

Accounting firms across the globe have followed in their footsteps, including in South America. Meet South America’s largest consulting firms with an audit and accounting heritage:
