EY

The organisation operates as a network of legally separate member firms coordinated by a UK company limited by guarantee. Member firms deliver assurance, tax, transaction and advisory/consulting services to corporate, public sector and other institutional clients. Value is created by combining sector and functional expertise with proprietary technology platforms for audit, data analytics, innovation facilitation and workforce mobility management. Strategy consulting capability has been expanded through acquisitions to deepen higher-value advisory offerings. Technology assets (audit platforms, analytics suites, mobility lifecycle tools and AI platforms) are primarily used to enhance service delivery efficiency, consistency and insight rather than as standalone products, and some are delivered as client-facing platforms embedded in ongoing engagements or managed services.

EY is a global professional services network headquartered in the United Kingdom, operating as Ernst & Young Global Limited and its member firms. It provides assurance (audit), tax, transaction and advisory/consulting services, and has built in-house strategy consulting capability through combinations such as EY-Parthenon. The network uses proprietary cloud platforms and data analytics tools, including audit workflow and analytics systems, innovation centres, and a mobility management platform, to deliver and differentiate its services.

EY generates revenue from organisations that procure audit, tax, transactions and advisory engagements, typically on time-and-materials, fixed-fee, or managed-services bases. Its customer base comprises large enterprises, multinational corporations, governments and other sizeable organisations that require external assurance, complex tax and transaction support, workforce mobility management and strategic advisory services across regions worldwide.
