How We Selected the Top 10 Audit Firms in Singapore
Finding the right audit firm takes more than comparing well-known names. We selected the top 10 audit firms in Singapore based on factors that matter to businesses when choosing reliable audit support.
Experience and Track Record
We looked at each firm’s experience in Singapore and the types of clients it serves. Firms with a strong track record across SMEs, growing companies and larger businesses received greater consideration.
Range of Audit Services
Audit needs can differ from one business to another. Therefore, we considered firms that offer statutory audits, assurance, internal audits and other related services that support businesses as they grow.
Industry Experience
Industry knowledge can make the audit process smoother and more focused. We considered firms with experience in sectors such as technology, financial services, construction, retail, manufacturing and professional services.
Local Market Knowledge
Singapore businesses must follow local financial reporting and regulatory requirements. As a result, we considered firms with a clear understanding of the local business environment and relevant reporting standards.
International Reach
Companies with overseas operations may need support across several markets. We considered whether firms have international networks or access to professionals who can support cross-border audit and reporting needs.
Reputation and Professional Standing
Trust is an important part of any audit relationship. We looked at each firm’s market presence, professional standing and reputation when preparing this list of audit firms in Singapore.
Business Size and Fit
Finally, we considered which types of businesses each firm is best suited to serve. This helped create a balanced selection covering Big Four, mid-tier and local firms rather than focusing on size or brand recognition alone.
Big 4 vs Mid-Tier Audit Firms
The Big Four — Deloitte, EY, KPMG and PwC — are known for their global reach and large specialist teams. Mid-tier audit firms, such as BDO, RSM and Baker Tilly, also serve listed companies and growing businesses in Singapore.
| Factor | Big Four Audit Firms | Mid-Tier Audit Firms |
| Typical clients | Large companies, listed firms and multinational groups | SMEs, growing companies and regional businesses |
| Global reach | Extensive international networks | Strong regional and international networks |
| Service range | Wide range of audit and specialist services | Broad services, but the range varies by firm |
| Specialist resources | Large teams across many industries and technical areas | Strong expertise, with smaller specialist teams |
| Partner access | Depends on the size and scope of the engagement | Often more direct for SME and mid-market clients |
| Audit fees | Often suited to larger and more complex engagements | Can offer greater flexibility for growing businesses |
| Complex audits | Well suited to large groups and cross-border operations | Well suited to many SME and mid-market audits |
| Best fit | Businesses with complex or global reporting needs | Businesses seeking expertise with a more flexible service model |
Which Audit Firm Is Best for Your Business?
The right audit firm depends on your business size, industry and reporting needs. Large companies with international operations may prefer global firms, while SMEs may benefit from local or mid-tier audit firms.
When comparing the top 10 audit firms in Singapore, consider:
- Business size: Choose a firm with the right resources for your company.
- Industry experience: Look for relevant sector knowledge and expertise.
- International reach: Global networks can support overseas operations and group audits.
- Services required: Consider audit, assurance, tax and other business services.
- Communication: Choose an accessible and responsive audit team.
- Budget: Compare fees based on the same scope of work.
Shortlist firms that match your needs, then compare their experience, proposed team, services and fees before making your decision.
Industries Served by Singapore Audit Firms
Singapore audit firms work with businesses across a wide range of industries, from financial services to manufacturing. Since each sector has different risks and reporting needs, relevant industry experience can make the audit process smoother.
Financial Services and Fintech
Banks, investment firms, payment providers and fintech companies face strict reporting and regulatory requirements. Audit firms serving this sector often focus on financial controls, risk management and accurate reporting.
Technology and Startups
Technology companies and startups can face issues linked to rapid growth, funding and overseas expansion. Auditors may review areas such as revenue, software costs, investments and financial controls.
Construction and Real Estate
Construction and property companies often manage long-term projects, contracts and high costs. Therefore, auditors need to understand project accounting, revenue recognition, asset values and related financial records.
Retail and Hospitality
Retailers, restaurants and hospitality businesses often process large numbers of daily transactions. Their audits may cover sales records, stock, cash handling and controls across different stores or locations.
Manufacturing and Engineering
Manufacturing businesses deal with stock, equipment, production costs and supply chains. Audit firms with sector experience can review these areas while checking whether financial records give a clear view of business performance.
Logistics and Transport
Logistics and transport companies may operate across several locations and markets. Auditors often review operating costs, assets, revenue records and controls linked to cross-border transactions.
Healthcare and Professional Services
Healthcare and professional services companies require special auditing expertise. Auditors experienced in the field can gain more knowledge about how the business earns money, operates, and keeps the accounting records.
Charities and Non-Profit Organisations
Charitable and non-profit organisations require good financial reports for transparency. The audit firm working in the non-profit field will analyse contributions, expenses, grants, etc.
How to Choose the Right Audit Firm
Choosing the right audit firm helps simplify the audit process and meet reporting requirements. Consider experience, qualifications, services and communication, not just price.
Check Qualifications and Professional Standing
Ensure the auditor has the required qualifications and professional standing in Singapore. Check relevant registration details through ACRA where necessary.
Look for Industry Experience
Choose a firm familiar with your industry, business model and common risks. Relevant experience can make the audit process more efficient.
Review the Range of Services
Check whether the firm provides statutory audits, internal audits, assurance, tax or advisory services that may support your future needs.
Ask Who Will Handle Your Audit
Find out who will manage the engagement, their experience and how involved the audit partner will be.
Compare Fees and Scope
Compare quotes based on both price and scope. Company size, complexity and audit requirements can affect the final fee.
Check Communication and Timelines
Choose a firm that communicates clearly about document requirements, deadlines and expected audit timelines.
Consider International Reach
For businesses with overseas operations, a firm with international capabilities can help coordinate audits and reporting across markets.
