Auditing in Practice: Understanding the Most Common Types of Engagements
Auditing plays a vital role in the financial life of any organisation. It builds trust in financial statements, ensures compliance with legislation, and supports management in making informed decisions. But auditing is not a single, uniform activity – it takes different forms depending on its purpose, scope, and intended users. This article provides an overview of the most common types of audit and assurance engagements in Ireland and explains how they differ in practice.
What Does Auditing Really Mean?
The word audit comes from the Latin audire, meaning “to hear.” In modern practice, it refers to the independent examination of an organisation’s financial information to determine whether it presents a true and fair view. An auditor acts as an impartial professional who protects shareholders, investors, creditors, and the public from errors, fraud, and misrepresentation.
However, auditing is not only about control. It can also be advisory and developmental – a tool for improving internal processes, strengthening governance, and enhancing decision-making.
The Statutory Audit
The most familiar form of audit is the statutory audit. Under the Companies Act 2014, certain Irish companies are required to have their annual financial statements audited. This typically applies to limited companies that exceed specific thresholds for turnover, balance sheet total, or number of employees.
In a statutory audit, the auditor examines the company’s financial statements and underlying records to assess whether they give a true and fair view of its financial position. This involves:
- reviewing accounting records, vouchers, and internal controls
- evaluating accounting policies and estimates
- testing significant balances such as inventory, receivables, and liabilities
- issuing an independent audit report included in the annual financial statements
The purpose is to provide shareholders, lenders, and regulators with reasonable assurance that the financial statements are reliable.
Audit Exemption and Small Companies
Many small Irish companies qualify for audit exemption if they meet certain criteria regarding turnover, balance sheet total, and employee numbers. Even when exempt, some owners or lenders may still request an audit to enhance credibility with banks, investors, or suppliers. Choosing whether to have a voluntary audit often depends on the company’s growth stage and stakeholder expectations.

Review Engagement – Limited Assurance
A review engagement provides a lower level of assurance than a full audit. Instead of detailed testing, the auditor performs analytical procedures and makes inquiries to determine whether anything has come to their attention that suggests the financial statements are materially misstated.
A review is suitable when management or external stakeholders want some independent assurance but do not require the depth of a statutory audit. It is often used for interim financial statements, group reporting packages, or due diligence exercises.
Compilation Engagement – Assistance with Financial Statements
In a compilation engagement, the accountant assists management in preparing financial statements based on the information provided by the company. The accountant ensures that the statements are properly formatted and comply with relevant accounting standards, but does not verify the accuracy of the underlying data or provide any assurance.
This service is particularly useful for small businesses and sole traders who maintain their own records but want professional help to ensure their accounts meet legal and presentation requirements.
Other Assurance and Agreed-Upon Procedures Engagements
Beyond audits and reviews, accountants and auditors in Ireland also perform a range of special purpose assurance engagements. These may include:
- certification of grant claims or project expenditure
- reports required for company formations, mergers, or capital increases
- verification of specific financial information, such as VAT returns or payroll compliance
- agreed-upon procedures engagements, where the auditor performs specific tests requested by the client or a third party
These assignments are tailored to particular needs and require the auditor to adapt their approach and reporting accordingly.
Choosing the Right Type of Engagement
The appropriate type of engagement depends on several factors: the size and complexity of the business, legal requirements, stakeholder expectations, and cost considerations. As a general rule, the greater the need for assurance and transparency, the more comprehensive the engagement should be.
It is advisable to discuss the options with a qualified auditor or accountant. They can help balance the level of assurance required with the associated costs and recommend the engagement that provides the most value for the business.
Auditing as a Tool for Improvement
Although auditing is often associated with compliance, it can also be a powerful tool for development. Through their work, auditors gain insight into a company’s systems, risks, and controls – and can identify opportunities for improvement. A good auditor is not just a checker of figures but a trusted adviser who helps the organisation become more efficient, transparent, and resilient.
A Matter of Trust
Regardless of the type of engagement chosen, the essence of auditing remains the same: trust. Trust that the numbers are accurate, that the business is managed responsibly, and that decisions are based on reliable information. In practice, auditing is not only about financial statements – it is about credibility, transparency, and professional integrity.
