What are assurance services?

Business owners, shareholders, investors, management teams, and regulators rely on the successful conduct of business operations, sound internal controls and processes, and the generation of credible financial and non-financial information.


These help owners to make thoughtful decisions and develop organisation policies. However, uncertainties in the data integrity or underlying operational procedures affect confidence.

Assurance can be summarised as regular risk management during normal organisational activity and the strength of a broader control framework.

Furthermore, assurance focuses on the assurance taken from the independent work of the organisation’s internal and external assurance providers.

Businesses primarily employ assurance services of chartered or certified accountants to assess risk, business performance, transparency, information system reliability, and validate their financial information.

It assures the shareholders, investors, and regulators that no fraudulent activities are conducted in your business, such as misuse of funds and misrepresented financial records. We can say auditing and assurance services may be correlated but are not identical.

How do assurance engagements work?

The International Auditing and Assurance Standards Board (IAASB) developed the Amendment International Framework for Assurance Engagements, which identifies five elements. These are:

●  A three-party relationship
It includes the existence of a three-party relationship: the auditors, the client management, and the intended users.

1. The auditor is the qualified person carrying out the assurance.
2. The client management is the party under scrutiny by the auditors and assists an auditor throughout the audit process.
3. The intended users or shareholders are responsible for employing an auditor, and they rely on and make informed decisions depending on the assurance outcome.
4. An agreed and appropriate subject matter

It is a piece of information given to the auditors by the responsible party to determine their opinions. It mainly includes the balance sheet, the income statement, and the cash flow statement.

●  Suitable criteria
It serves as the base for auditors or the appropriate measures from which they will adequately assess and evaluate the agreed subject matter. It may include the conditions or rules like financial standards the client adheres to while drafting their financial statements.

●  Adequate and appropriate evidence
An auditor must have sufficient and appropriate evidence to validate the information the clients’ management provided in a subject matter and provide their opinions on the findings.

●  A written report
After the auditors have performed their tasks, from validating a subject matter against specific benchmarks and collecting sufficient appropriate evidence, the final step is to issue a written assurance report.

What are the benefits of assurance?

The reports generated by assurance services are compiled by third-party audit firms, providing peace of mind to shareholders. The assurance reports are objective, unbiased, and reliable.

It adds credibility to business processes and systems. The reports may consist of any improvement measure required in your business. You can use this information to improve business processes and reduce risks. The assurance report assists you in preparing for worst-case scenarios and implementing strategies that can control your business through economic uncertainties.

It positively impacts your business’s long-term profitability as the reports ensure your internal controls and governance are in place. Their findings are drafted on the report that helps you reduce errors, thus, saving time and money in rectifying them.

Assurance reports give a closer look at your business through the eyes of a skilled professional, facilitate the running and management of the company, improve the process of obtaining finance, ensure better controls to increase profit, and keep confidence in internal controls.

It is difficult for businesses to comply with all the changing rules, regulations, and guidelines led down by the government, accounting principles, or industry standards. However, conducting statutory audits can ensure you stay compliant with regulatory obligations.

But, the problem is, at times, you can miss out on specific areas during an audit due to lack of time or to reduce audit costs. Assurance reports ensure no areas are missed out as the top-level professionals of the country perform these checks with extensive knowledge and expertise.

Assurance checks make sure your audits are adequately done. It assists in building a business reputation and confirms to the regulators, shareholders, and investors that the organisation is performing to expectations and that its financial health is in order.

Audit vs Assurance

The critical differences between assurance services vs audit services are given below.

1. Independence: Audits can be conducted by internal or external auditors, but external professionals are solely responsible for conducting assurance processes. Assurance proves the validity of an audit.
2. Order: Assurance determines the validity and accuracy of an audit. Therefore, companies need to perform an audit first, followed by assurance checks to provide additional support for the conclusions drawn from an audit.
3. Scope: Audits include the analysis of an organisation’s financial reports by examining available financial data to determine the overall accuracy of their reporting methods. Assurance processes involve analysing one or multiple audit reports of an organisation to assess the validity of an audit.
4. Standards: Auditing processes follow international auditing standards to determine best practices and eliminate inaccuracies. The assurance standards may be defined per region or industry.



Assurance plays an integral part in your audit process. The auditors follow strict ethical codes, obtain evidence that the required criteria have been met, have sufficient evidence to substantiate an opinion and supply a written report. These reports help external auditors better do their job and finish the audit process early.

Assurance reports ensure there is no misrepresentation in financial records, no misuse of funds, no fraud, and no problem activities done in the company.

And audit reports confirm your financial records are ethically, fairly, and accurately presented. It checks whether your accounting reports meet government regulations, accounting principles, and industry standards.
