Brief Guide: External Audit

An external audit, including compliance audits, is a fundamental part of modern business for transparency, compliance, and accountability. It’s done by an external auditor who reviews an organisation’s financial records and operations to verify accuracy and compliance. Internal and external audits serve different purposes and benefits for an organization; internal audits are to improve internal processes, while external audits focus on compliance with regulations and guidelines set by authorities and are done by third party auditors for stakeholders like investors, lenders, and regulatory bodies.

This brief looks at the purpose, process, benefits, challenges, and best practices of external audits and their importance in building trust and integrity.

What is an External Audit?

An external audit is conducted by independent auditors or audit firms not part of the organisation. External auditors conduct financial statement audits to ensure compliance with GAAP requirements using their expertise and a team approach. By providing objective information, external auditors ensure the financial statements show a true and fair view of the organisation’s financial position. The findings of the external audit are documented in the external audit report which gives insight into the organisation’s financial position and compliance with the law.

Internal vs External Audits:

Internal audits are ongoing processes done by internal teams to improve efficiency and control. Internal and external auditors serve different purposes, with internal auditors focusing on improving operations and external auditors providing independent assessments. External audits provide stakeholders with an independent view of compliance and accountability. Both are important with internal audits supporting external audits by “preparing the ground”.
