ONO Partnership is a Lagos-based professional services firm providing audit and assurance, taxation, internal controls and risk (including ICFR), financial advisory and accounting support, financial due diligence, business valuation support, and forensic audit and investigation services.
Partner-led engagements focused on risk, judgment and reporting quality.
For more than a decade, ONO Partnership has supported boards, management teams, investors and regulators across complex and highly regulated environments. Our experience spans audit and assurance, taxation, internal controls and financial advisory, delivered with professional judgment and disciplined execution.
Our engagements are led by experienced partners who remain actively involved from planning through execution and final reporting, ensuring accountability, continuity and informed professional judgment at every stage.
Our work is supported by structured arrangements covering independence, ethical conduct, confidentiality and quality control, helping ensure objectivity, consistency and reliability across all engagements.
Established in 2011, ONO Partnership works with boards, management teams, investors and regulators to strengthen financial integrity, support compliance and enable informed decision-making in complex, highly regulated environments.
Our work is grounded in professional standards, ethical discipline and a focus on outcomes that matter to stakeholders.
Choosing a professional services firm is ultimately about trust, judgment and reliability. Clients work with ONO Partnership because of how we approach our work — not because of marketing claims.
We begin by understanding the organisation’s objectives, reporting environment and stakeholder expectations.
We assess risk, determine scope, agree timelines and confirm stakeholder reporting requirements before fieldwork begins.
Work is performed using structured methodologies, evidence-based analysis and partner oversight.
We communicate findings, implications and recommended actions clearly and practically.
Whether responding to regulatory expectations, supporting governance or informing critical decisions, we help organisations act with clarity and confidence.
