In short: Young companies wanting an app and a fixed annual plan: Osome or Sleek. Small companies wanting bookkeeping priced by transaction volume: Leftright Corporate or 3E Accounting. Companies needing a statutory audit or more tax and advisory support: Tan, Chan & Partners or Baker Tilly.
Which accounting firm suits you depends on the size and complexity of your company. For a young company that wants an app and a fixed annual plan, look at Osome and Sleek. For a small company that wants a small local firm with prices set by transaction volume, look at Leftright Corporate and 3E Accounting. If your company needs a statutory audit or more tax and advisory support, look at Tan, Chan & Partners and Baker Tilly.
Many “best accounting firm” lists for Singapore are years old, or are written by a provider that ranks itself first. This guide groups six firms by type, sets out what each one says on its own website, and explains how to choose. It focuses on firms that serve SMEs, not only the Big Four.
How we chose
We started from firms that appear often when Singapore businesses search for an accounting firm, then kept only those whose services we could confirm on their own websites in October 2026. We looked at:
- Type of firm. Online platform, small local firm, or audit and advisory firm.
- Who it serves. Whether the firm says it works with SMEs and small companies.
- Scope. Bookkeeping, year-end financial statements, corporate tax (ECI and Form C-S), GST returns, XBRL and audit.
- Price transparency. Whether the firm publishes prices, and what they include.
We did not rank firms by review scores, awards or client numbers, because we could not verify them, and we left out paid directories. The list is grouped by type rather than ranked.
FYAdvisers is a free matching service for Singapore businesses. Firms do not pay to appear in this list, and we describe each one only from what it says on its own website.

How to choose
Start with what your company actually needs. A small company with few transactions and no audit requirement mainly needs bookkeeping, financial statements, ECI and Form C-S, and annual return support. An online platform or small local firm usually covers that. If your company does not qualify for audit exemption, or has group companies, foreign income or complex tax questions, an audit and advisory firm may suit you better. Our accounting firm page explains the filings and deadlines in more detail.
Then ask every shortlisted firm the same questions:
- What exactly is included? Bookkeeping, financial statements, ECI, Form C-S, GST returns, annual return and XBRL.
- How do you count transactions? And what happens if you go over your band.
- Which software do you use? Ask whether you get your own login and keep your records if you leave.
- Who handles our account? Ask about qualifications, and who signs any audit.
- What does year two cost? Compare renewal prices, not only the first-year offer.
If you also need a named company secretary, see our list of corporate secretarial services in Singapore. If you have staff, payroll outsourcing is often bought alongside accounting.

Frequently asked questions
What types of accounting firm are there in Singapore?
Broadly three. Online platforms such as Osome and Sleek sell fixed plans with an app for receipts and an assigned accounting team. Small local firms keep books and file returns for SMEs, often with prices set by transaction volume. Audit and advisory firms, from long-established local practices to members of international networks, add statutory audit, tax advisory and work for larger or more complex companies.
How much does an accounting firm cost in Singapore?
It depends on transaction volume and which filings are included. When we checked in October 2026, Leftright listed monthly bookkeeping from S$110 a month for fewer than 25 transactions, 3E Accounting listed bookkeeping from S$500 a year before GST, Osome listed plans from S$75 a month and Sleek from S$75 a month, both billed annually. Tax filing, financial statements, GST returns and XBRL are often priced separately, so ask for an itemised quote.
Does my company need an audit?
Not always. Under ACRA's small company concept, a private company is generally exempt from audit if it meets at least two of three criteria: revenue of S$10 million or less, total assets of S$10 million or less, and 50 or fewer full-time employees. Group rules apply to subsidiaries. If you do need an audit, it must be done by a public accountant registered with ACRA.
Can FYAdvisers help me find an accounting firm?
Yes. FYAdvisers is a free matching service for Singapore businesses. You describe your company, roughly how many transactions you have and what you need, a concierge confirms your requirements, and we introduce one to five accounting providers that fit. You choose which ones to speak to, and the service is free for businesses.
