The firm delivers professional services across four core pillars — Audit & Assurance, Advisory & Consulting, Tax Services, and Financial Advisory — and extends these with specialized modules such as Consulting, Tax, Financial Advisory, and Operations; key sub-offerings include Engineering, AI & Data, the Digital Factory, Cyber Services, Human Capital, Enterprise Technology & Performance, Strategy & Transactions, and Risk, Regulatory & Forensic.

The offering is organized on a platform-plus-modules architecture, with industry-specific practices serving Banking & Capital Markets, Insurance, Investment Management & Regulatory, Real Estate, Government & Public Services, Life Sciences & Healthcare, Technology/Media/Telecom, Consumer, and Energy, Resources & Industrials. Technology delivery is supported by strategic alliances with SAP, Oracle, Salesforce, ServiceNow, Workday, AWS, Google, and Atlassian, and increasingly by proprietary capabilities such as the Digital Asset Accelerator Centre (DA2C), the Deloitte AI Institute Luxembourg, the Change & Technology Unit, and a next-generation managed service for funds and regulatory reporting that processes more than 175,000 PRIIPs data points monthly and executes registrations in over 65 jurisdictions.

The firm earns revenue from professional services fees set on a custom, engagement-based pricing model with multi-year contracts; there are no publicly disclosed standard pricing tiers. Distribution runs through direct, relationship-based enterprise sales targeted at large multinational corporations, financial institutions, investment funds, and government and EU institution clients. Leadership transitioned from John Psaila to Joachim Heukmes as CEO and Managing Partner effective June 1, 2026, coinciding with the largest single partnership expansion in the firm's history.
