Assurance services are professional services provided by independent practitioners to improve the quality and reliability of information presented by an organization. While audits of financial statements are the most recognized form of assurance, the scope of assurance services has expanded significantly to include a wide variety of financial and non-financial areas. These services play a vital role in enhancing transparency, fostering stakeholder confidence, and supporting sound decision-making. Understanding the different types of assurance services is essential for appreciating their value in diverse business contexts.
1. Financial Statement Audits
A financial statement audit is the most common type of assurance service. It involves an independent examination of an organization’s financial statements to provide reasonable assurance that they are free from material misstatement, whether due to fraud or error.
