Where competence becomes control, and control protects the enterprise.

CoreTrex Partners is a specialist advisory firm helping organisations build the controls, governance, and tax discipline that allow a business not merely to operate, but to endure.

Our conviction

Most firms advise on paper. We turn knowledge into practice — translating two decades of banking, governance, and academic rigour into controls that work on the ground, governance that holds, and tax positions that stand.

— The founding principle of CoreTrex Partners
What we do

Four disciplines, one purpose: that your business survives and is trusted.

Our service lines map directly to the threats that quietly undo good companies — weak controls, poor governance, and tax exposure.

01 / Control

Internal Control & ICFR

The core of our practice. We design and embed internal control over financial reporting, so the numbers can be trusted, the business protected, and management held to account.

  • COSO 2013 control framework design
  • Risk and control matrices (RACM)
  • Control testing, remediation & monitoring
  • Enterprise risk management
  • SOX-style ICFR readiness & certification support
  • Entity-level & management review controls
02 / Continuity

Business Survival & Assurance

Where the disciplines converge. We bring assurance, operational rigour, and continuity planning together, so the business withstands shocks, scrutiny, and the test of time.

  • Combined assurance mapping
  • Fraud risk & forensic review
  • Process & operational diagnostics
  • Capacity building & advisory retainers
  • Business continuity & crisis response planning
  • Third party & vendor assurance reviews
03 / Governance

Corporate Governance

Board structures, company secretarial discipline, and the governance architecture that earns the confidence of regulators and investors, and stands up to scrutiny from every direction.

  • Board & committee structuring
  • Company secretarial & statutory compliance
  • Governance codes & policy frameworks
  • Regulatory liaison (CAC, CBN, SEC, FRCN)
  • Outsourced company secretarial retainership
  • Board evaluation & effectiveness reviews
04 / Tax

Tax Advisory & Compliance

Tax positions built on academic depth and practical experience. Every filing, planning decision, and exposure assessment is compliant, defensible, and aligned to the business.

  • Tax compliance & planning
  • Tax risk & exposure assessment
  • Regulatory filing & representation
  • Training on fiscal compliance
  • Transfer pricing documentation & review
  • Tax health checks & dispute resolution support
How we work

Diagnose. Design. Embed.

We do not leave behind documents that gather dust. We measure success in reduced errors, cleaner reporting, and controls that are actually used.

01

Diagnose

We assess the real control, governance, and tax landscape of your business — not the one on paper, but the one in practice.

02

Design

We build frameworks tailored to your size, sector, and regulator: practical, proportionate, and grounded in recognised standards.

03

Embed

We implement alongside your people, transfer the knowledge, and stay until the controls run on their own and the outcomes are measurable.

Who we are

Three practitioners. Each one a discipline mastered.

CoreTrex was founded on a simple idea: that those who have studied a field deeply and practised it at the highest level make the best advisors in it.

The foundation

Our practice is built on a published body of knowledge.

CoreTrex is unusual among advisory firms: our control methodology is set out in full, in print, across twenty-five chapters and ten appendices.

It is the same framework we bring to your business — the international consensus of COSO 2013 made practical for the regulatory world that Nigerian and African organisations actually inhabit.

"A practitioner's reference work that is, above all, readable."

Let's talk

Build a business that survives scrutiny.

Whether you need controls that hold, governance that earns trust, or tax positions that stand — we begin with a conversation.
