About The Company

The OA Journey: Redefining Professional Excellence in ASEAN

Since its inception in 2011, OA International Holdings Pte. Ltd. has evolved far beyond its origins as a specialised accounting firm. Today, it operates under its unified brand identity — OA Group of Companies (OA GoC) — a regional professional services platform built on a singular belief: that professional expertise, when applied with purpose, can be a force for growth not just for businesses, but for people and society.

What began as Singapore Corporate Services was reimagined in 2016 into OA Group of Companies — not merely a restructuring, but a deliberate shift in mindset. From a compliance-focused practice, OA GoC set out to become a partner in growth, delivering integrated audit, tax, compliance, and advisory solutions that enable businesses to scale with confidence across borders.

From Compliance to Purpose-Driven Growth

At its core, OA GoC believes that professional services should not stop at ensuring compliance — it should unlock clarity, confidence, and capability for businesses to move forward.

This belief is reflected in how the organisation works with its clients:

  • Helping SMEs transform through cloud accounting and digital adoption
  • Supporting cross-border expansion into ASEAN and China
  • Enabling better governance, transparency, and decision-making
  • Through this, OA GoC contributes to building a stronger, more resilient business ecosystem — one where growth is sustainable and responsible. 

A Culture That Powers Growth

What differentiates OA GoC is not just what it does, but how it develops its people.

Guided by its philosophy of “Powering Growth”, the organisation has built a culture where learning, ownership, and progression are embedded into everyday work:

  • 80% of its workforce is professionally qualified or on the path to qualification
  • Employees are continuously upskilled in digital tools, advisory capabilities, and emerging technologies
  • Career journeys are intentionally designed — from interns to leaders

Stories within the organisation reflect this commitment. Individuals who joined as interns or junior staff have grown into leadership roles across regions — not as exceptions, but as the intended outcome of a structured development pathway.

This is how OA GoC views impact: when people grow, businesses grow — and when businesses grow, communities benefit.

Building a Future of Business For Good

Looking ahead, OA International Holdings Pte. Ltd., through its brand OA Group of Companies, is focused on redefining what a professional services firm can be.

By integrating digital transformation, automation, and AI into its service model, OA GoC is not only improving efficiency — it is reshaping the role of professionals from processors of information to strategic advisors.

At the same time, the organisation is actively contributing to the broader ecosystem:

  • Developing future-ready talent through structured training and internships
  • Supporting SMEs in their transformation journeys
  • Creating pathways for cross-border opportunities

In doing so, OA GoC aligns with a growing belief that businesses should be measured not only by profit, but by their impact on people and society — a philosophy at the heart of the Brands For Good movement, where purpose-driven enterprises are recognised for integrating social responsibility into their core operations. 

Vision for the Future

At OA Group of Companies, professional excellence is not defined by technical precision alone — but by the ability to create meaningful growth for clients, develop people with intention, and contribute to a better business ecosystem across the region.

Because in the end, growth is not just about moving forward —

it is about bringing others forward with you.

About The Leadership

Alan Chang is the founder and Group CEO of OA Group of Companies, a regional professional services platform built on a simple but powerful belief — that businesses can grow profitably while uplifting the communities they serve.

With over two decades of experience spanning Big Four firms and international advisory roles, Alan has transformed OA from a traditional compliance practice into a purpose-driven organisation that partners SMEs across ASEAN in their journey toward sustainable growth.

At the core of his leadership is a commitment to “growth with purpose.” Beyond delivering audit, tax, and advisory services, Alan has positioned OA as a catalyst for business transformation — helping entrepreneurs strengthen governance, embrace digitalisation, and build resilient, future-ready organisations.

What distinguishes Alan is not just his technical expertise, but his conviction that professional services should extend beyond compliance into impact. From mentoring SMEs and supporting startups to contributing his time in pro bono and public roles, he exemplifies a form of leadership that aligns closely with the Brands for Good philosophy of activist entrepreneurship — using business as a platform to create meaningful societal value.

Under his leadership, OA continues to evolve as a purpose-led organisation — one that develops people, empowers businesses, and contributes to the broader ecosystem, proving that doing good and doing well are not mutually exclusive, but deeply interconnected.
