Introduction
Audits are an essential part of Singapore’s business and regulatory landscape. They provide assurance that a company’s financial statements are accurate, comply with the Singapore Financial Reporting Standards (SFRS), and meet the legal requirements under the Companies Act.
However, not all audits are the same. Businesses, non-profit organisations, and government agencies require different types of audits depending on their objectives, stakeholders’ needs, and regulatory obligations. Understanding the different types of audit services in Singapore helps you choose the right one for your circumstances, ensuring compliance while maximising business value.
