What Grant Thornton Nigeria does

Grant Thornton Nigeria is a professional services firm and an independent member of the Grant Thornton International Ltd (GTIL) global network, providing assurance, tax, advisory, and corporate accounting and outsourcing services to enterprise and mid-market clients across Nigeria. The firm employs 221 people across three offices in Abuja, Lagos, and Port Harcourt, serving eight primary verticals: energy and resources, financial services, food and beverage, hospitality and tourism, not-for-profit, public sector, real estate and construction, and technology.

The service portfolio is organized into four lines. Assurance covers financial statement audits, reviews, compilations, IFRS conversions, and controls reporting, supported by global audit technology shared across the GTIL network. Tax covers compliance, transaction planning, VAT, transfer pricing, international and expatriate tax, and private wealth planning. Advisory spans governance, risk and compliance, forensic services, IT audits and penetration testing, recovery and reorganization, transactional services, and M&A. Corporate accounting and outsourcing delivers bookkeeping, business process outsourcing, company secretarial services, HR consultancy, and payroll processing on an ongoing managed services basis.

The firm generates revenue through project-based and recurring professional services engagements, with custom pricing determined by scope and complexity. Go-to-market is direct enterprise and mid-market client engagement through relationship management, supported by thought leadership publications (Women in Business, sustainability research), events and webinars, and the firm's digital presence. The competitive position rests on the GTIL global brand and network, integrated cross-border delivery capability, and multi-vertical industry coverage, though no specific financial metrics, customer logos, or headcount trends are publicly disclosed.
