Professional services

Professional services sell expert judgement: audit, tax, legal advice, management and technology consulting, engineering design and outsourced knowledge work. In the US alone, professional, scientific and technical services added about US$ 2.5 trillion of value in 2025 (BEA, calculated as the average of quarterly annual rates), and the four largest networks (Deloitte, PwC, EY and KPMG) earned about US$ 220 billion worldwide (calculated). Fee pools are concentrated in the US and Europe, while delivery increasingly sits in India.⁶

India. India hosts 2,117 global capability centres employing more than 2.36 million people with estimated revenue of US$ 98.4 billion in FY26 (industry estimate), much of it finance, legal, engineering and analytics work for global firms⁵. The Big Four and Indian firms also run large delivery centres here, and EY's EMEIA region, which includes India, was its fastest-growing in FY25 at 5.5% in local currency².
