As a qualified accounting firm registered with ACRA, we handle your full-set bookkeeping, GST submissions, unaudited financial statements, and corporate tax filings. So you can focus entirely on running your business.
Our accounting services for small businesses in Singapore start from S$200 per month for active companies, with transparent pricing based on your company’s activity level. There are no hidden fees and no surprise bills at year-end.
Why Small Businesses in Singapore Outsource Their Accounting
Running an in-house accounting function is expensive. A full-time accountant in Singapore costs between S$3,000 and S$5,500 per month in salary alone — before CPF contributions, benefits, and training. For most small businesses, this overhead is unnecessary.
Outsourcing your accounting to a professional firm gives you access to a qualified team for a fraction of that cost, while ensuring your books are always accurate, your filings are always on time, and your business stays fully compliant with IRAS and ACRA requirements.
The cost comparison for a typical SME:
| Â In-House Accountant | OneStop Outsourced Accounting | |
|---|---|---|
| Monthly cost | S$3,000–S$5,500 | From S$200/month |
| CPF contributions | Required | Not applicable |
| Compliance knowledge | One person | Full team |
| Continuity risk | Staff turnover | None |
| Scalability | Fixed headcount | Scales with your needs |

Singapore Accounting Compliance: Key Deadlines Every Small Business Must Know

As your accounting service provider, OneStop Professional monitors and manages all these deadlines on your behalf.
| Obligation | Deadline | Notes |
|---|---|---|
| ECI Filing | Within 3 months of financial year end | Estimated Chargeable Income submitted to IRAS annually |

When you engage OneStop Professional, our team proactively tracks all of these deadlines and notifies you well in advance, so your business never faces unexpected penalties or late filing fees.
Do Small Businesses in Singapore Need an Audit?
Most small businesses qualify for Singapore’s audit exemption under the Companies Act. Your company is exempt from audit if it meets at least two of the following three criteria in the past two consecutive financial years:
- Annual revenue of S$10 million or less
- Total assets of S$10 million or less
- 50 or fewer employees
If your company qualifies, you are not required to have your accounts audited. Instead, you need to prepare an unaudited compilation of financial statements for your AGM and ACRA filing, which OneStop Professional handles on your behalf.
If your business does not qualify for the exemption, our team can also assist with statutory audit referrals through our network of approved auditors.

Outsourced Accounting FAQs
Accounting Services for Small Business in Singapore FAQs
Accounting services for small businesses in Singapore start from S$200 per month for dormant companies and S$600 per month for active companies, based on activity-level pricing. Additional annual fees apply for unaudited financial statement preparation (from S$300), corporate tax filing (from S$431), and company secretarial services (S$720/year). Contact us for a full quotation tailored to your company's needs.
Most small businesses in Singapore need the following: full-set bookkeeping, preparation of unaudited financial statements, corporate tax return filing (ECI and Form C-S), and ACRA annual return filing. If your annual turnover exceeds S$1 million, GST registration and quarterly filing are also required. Companies with corporate shareholders may also need XBRL conversion for ACRA filing.
Yes. Under the Singapore Companies Act, all registered companies must maintain proper accounting records for a minimum of five years and file annual returns with ACRA and corporate tax returns with IRAS. While you are not required to hire a full-time accountant, you must ensure these obligations are met. Most small businesses engage an outsourced accounting firm to handle this cost-effectively.
Bookkeeping refers to the day-to-day recording of financial transactions — income, expenses, and bank entries. Accounting refers to the broader process of interpreting, classifying, and reporting on those records, including the preparation of financial statements, tax computations, and compliance filings. At OneStop Professional, our SME accounting service includes both bookkeeping and full accounting functions.
Yes. Outsourced accounting is particularly well-suited for small businesses with low-to-moderate transaction volumes. It eliminates the cost of a full-time hire, ensures you never miss a statutory deadline, and gives you access to a qualified team whenever you need advice. For dormant or semi-active companies, our accounting fees start from as little as S$200 per month.
Accounting involves the preparation of financial records and statements. An audit is an independent examination of those statements to verify their accuracy. Most small businesses in Singapore qualify for the audit exemption under the Companies Act, meaning they need accounting (to prepare their financial statements) but not an audit. OneStop Professional can advise whether your company qualifies for the exemption.
Yes. If your annual taxable turnover exceeds S$1 million, or you anticipate reaching this threshold, we can assist with GST registration and manage your quarterly GST returns on an ongoing basis. For companies already GST-registered, we take over the filing responsibility as part of your accounting engagement.
Yes. In addition to annual compliance work, we offer monthly, quarterly, and semi-annual management accounts for SMEs that need regular visibility into their financial position. This service is particularly useful for businesses with investors, active cash flow management needs, or multiple revenue streams.
