EY

EY creates value by combining specialist professional expertise with proprietary delivery platforms, methodologies and global member-firm reach. Revenue is generated predominantly from client service engagements across assurance, tax, consulting and transactions, with technology acting as embedded infrastructure that improves delivery quality, standardisation and client stickiness. Rather than monetising as a mass-market software vendor, EY uses digital products to support premium advisory, compliance and transformation work.

EY is a global professional services organisation operating through member firms under the Ernst & Young Global Limited structure. It provides audit and assurance, tax, consulting, transaction advisory and related technology-enabled services to large organisations, financial sponsors and finance leaders. Its proprietary digital tools, such as audit, tax, transformation and M&A workflow platforms, primarily support and enhance service delivery rather than acting as broad standalone software businesses.

The company makes money mainly through fee-based client engagements, including project work, managed services, retainers and specialist advisory mandates. Its customers are principally enterprise clients, corporate finance and tax teams, private equity firms, and senior transformation leaders who buy EY for regulatory expertise, programme execution, risk reduction and access to scaled multidisciplinary teams.
