Introduction

In Singapore, audit services are not just about fulfilling a legal obligation — they play a critical role in maintaining business transparency, investor confidence, and operational efficiency. The Accounting and Corporate Regulatory Authority (ACRA) requires certain companies to have their financial statements audited annually. But audits go far beyond statutory compliance.
