How AG Prevents Audit Delay

For audit assignments with a tight deadline, AG will perform an interim audit service, normally 2-3 months before the financial year-end. This is to minimise the audit work and time required to conclude the final audit after the financial year.

To facilitate smooth audit procedures, an audit requirement checklist will be tailor-made according to the client’s business model. Our audit company will run through the checklist with our clients so that they can prepare themselves for our satisfying audit reports in advance.

Our audit firm employs the risk-based audit methodology suggested by the Singapore Standards of Auditing.

In the audit planning stage, we will perform data crunching to identify key risk areas for targeted audit testing, enabling us to focus on critical areas that significantly reduce time, process and cost.

All audit engagements will be assigned to at least one senior auditor and supervised by our audit managers to monitor audit progress and quality. Additionally, our audit partners will robustly review and approve the audit time schedule to ensure our prompt service delivery.

Successful Audit Case Study

Client A is a subsidiary (“ABC”) of a foreign-listed company, with approximately US$30mil in revenue per annum.

The holding company requires ABC to submit its auditor report by the end of February every year. However, the auditor of ABC failed to meet the deadline and finalised the audit around the end of March.

This seriously delayed the group reporting process and dividend repatriation by ABC to its holding company.


AG Audit Solution

We performed an interim audit and prepared an audit services checklist to better cooperate and communicate with Client A’s accounting team.



We managed to finalise our audit in early February, 3 weeks before the deadline.

Client B (“BCD”) is a construction company with project revenue of more than S$10mil. Audit of BCD was qualified every year by its previous auditor due to improper project budgeting and cost allocation.

AG Solution

AG helped to revamp its business model by creating a cost centre, where BCD will outsource all projects to it.



Client B’s tax payable has been reduced, and its auditor report has improved from a qualified opinion to a clean report.

Frequently Asked Questions About Auditing Services in Singapore

It will depend on the size and financial status of your company. In a transformative move, the Companies (Amendment) Bill 2014, sanctioned by Parliament in October 2014, ushered in pivotal changes, notably the introduction of the “Small Company” concept. This groundbreaking amendment brings significant implications for private companies in Singapore, offering an audit exemption for those meeting specific criteria over the immediate past two consecutive financial years.


To qualify as a “Small Company,” private entities must meet at least two of the following three criteria over the immediate past two consecutive financial years:


  1. Total Annual Revenue: ≤ S$10m
  2. Total Assets: ≤ S$10m
  3. Number of Employees: ≤ 50

The audit exemption applies to financial years beginning on or after the change in the law (1 Jul 2015). Transitional provisions are in place for the first two years after the change.

Total revenue and assets are determined by accounting standards and the figures in the financial statements.

The number of employees is based on the count of full-time employees at the end of the financial year.

Yes, a private company with corporate shareholders can qualify for the audit exemption, eliminating the previous requirement for exempt private company status.

It will depend on the size and revenue of the subsidiary. For a subsidiary to qualify for the exemption, the group it belongs to must qualify as a small group on a consolidated basis. If the group doesn’t qualify and the holding company audits consolidated statements, the subsidiary must engage an auditing company to conduct the audit.

There are 4 types of audit opinions:


1. Unqualified Opinion: The Gold Standard

The coveted unqualified opinion, also known as a clean opinion, signifies that the financial statements present a true and fair view. It’s the gold standard, indicating transparency and adherence to accounting principles.


2. Qualified Opinion: Highlighting Exceptions

A qualified opinion is issued when auditors identify specific issues within the financial statements. While the overall presentation is deemed accurate, this opinion highlights areas that require attention or clarification.


3. Adverse Opinion: Flagging Material Misstatements

An adverse opinion is a red flag, indicating material misstatements within the financial statements. Stakeholders are alerted to significant issues that impact the accuracy and reliability of the presented information.


4. Disclaimer of Opinion: Insufficient Information

In cases where auditors lack adequate information to form an opinion, a disclaimer of opinion is issued. This underscores the importance of providing comprehensive data for a thorough audit assessment.


These audit opinions provide a professional assessment of a company’s financial statements, instilling confidence in stakeholders and ensuring regulatory compliance.

The primary difference between internal and external audits lies in their objectives, scope, and whom they serve.


Internal audits are conducted by the organisation’s own audit department and focus on evaluating the efficacy of internal controls, processes, and risk management practices. This type of audit aims to improve operational efficiencies and compliance within the organisation, serving the management team with insights and recommendations.


External audits, on the other hand, are performed by independent auditors or audit firms. These auditing services primarily assess the accuracy and fairness of an organisation’s financial statements to ensure compliance with accounting standards and regulatory requirements. External audits are critical for stakeholders outside the organisation, such as investors, creditors, and regulators, providing them with assurance about the company’s financial health and integrity.

Audit services play a crucial role in enhancing a company’s financial credibility and operational integrity. By providing an objective assessment of financial statements, audit services help identify inefficiencies, reduce the risk of fraud, and ensure compliance with regulatory standards. This process not only builds trust with stakeholders but also offers valuable insights for improving financial performance and strategic planning.

Yes, AG’s audit services are well-equipped to handle complex financial structures. Our team of expert auditors possesses the knowledge and experience required to navigate intricate financial landscapes. By employing the latest auditing techniques and technology, we ensure a thorough examination of your financial operations, regardless of complexity, offering tailored services that address your unique challenges and compliance requirements.
