Running a business in Singapore means dealing with ACRA filings, IRAS tax deadlines, and GST returns whether you like it or not. Many business owners only start searching for the best accounting firms Singapore after they have already missed a deadline or received a penalty notice from IRAS. That is usually the moment they realise bookkeeping is not something to handle in spare time between sales calls and hiring.
This guide looks at what actually separates a reliable accounting partner from one that just sends invoices and hopes for the best. We will walk through three accounting firms that stand out for Singapore SMEs, explain how they were selected, and compare them across the factors that matter most: pricing clarity, service scope, technology, and responsiveness. By the end, you should have a much clearer idea of which type of firm fits your stage of business, and what questions to ask before signing anything.
Best Accounting Firms Singapore
Before naming names, it helps to compare them side by side. The table below summarises how these three firms differ in focus and structure.
| Rank | Business | Best For | Experience | Location | Website |
|---|---|---|---|---|---|
| 1 | Osome | Tech-savvy startups and e-commerce sellers | Founded 2017 | 80 Robinson Road, Singapore | osome.com/sg |
| 2 | Sleek | Company incorporation bundled with accounting | Founded 2017 | 160 Robinson Road, #14-04, Singapore 068914 | sleek.com/sg |
| 3 | Counto | Unlimited transactions and revenue-based pricing | Founded 2019 | 8 Marina View, Asia Square Tower 1, Singapore | counto.sg |
Quick Summary Table
| Business | Why We Recommend It |
|---|---|
| Osome | Combines an in-house accounting platform with human accountants, and specialises in supporting e-commerce and cross-border sellers |
| Sleek | Bundles incorporation, corporate secretary, and accounting into one workflow, useful for founders who want fewer vendors to manage |
| Counto | Built around AI-assisted bookkeeping and transparent, revenue-tiered pricing rather than hourly billing |
These three names come up repeatedly across independent SME reviews and comparison articles because they take different approaches to the same problem: keeping a Singapore company compliant without turning the founder into a part-time bookkeeper. Below, we go through each one in more detail.
Osome
Why We Ranked It
Osome earns a place among the best accounting firms Singapore because it was one of the earlier providers to combine software and human accountants into a single service rather than offering one or the other. Instead of handing you a subscription and leaving you to figure out the categorisation yourself, Osome pairs its platform with accountants who review entries, prepare tax filings, and handle XBRL submissions.
Overview
Osome started in Singapore in 2017 and has since expanded to Hong Kong, the UK, and the UAE, with Singapore remaining its headquarters. The firm positions itself as a financial operating system for entrepreneurs, particularly those running online stores or cross-border operations. Its growth across four markets in under a decade reflects a business model built around solving repetitive compliance work through automation rather than manual processing.
This regional footprint is one reason Osome regularly appears among the best accounting firms Singapore, since it brings cross-border experience that many boutique local firms simply do not have. For founders managing sales across multiple countries or currencies, this kind of infrastructure can make day-to-day compliance considerably less stressful. It also means the firm has had to build systems that hold up under regulatory scrutiny in more than one jurisdiction, which tends to translate into more disciplined processes at home in Singapore as well.
Why We Selected Them
Their specialisation in e-commerce accounting stands out. Osome connects directly with platforms like Shopify, Lazada, Shopee, and Amazon, which matters for online sellers who would otherwise spend hours reconciling marketplace fees and refunds manually.

Best For
Osome suits founders running online stores, digital businesses, or companies with multiple sales channels who want their bookkeeping to sync automatically rather than being entered by hand.
Sleek
Why We Ranked It
Sleek is included among the best accounting firms Singapore because it solves a specific pain point: founders who need incorporation, a corporate secretary, and accounting all handled without juggling three separate vendors. This matters most for new companies and foreign entrepreneurs setting up in Singapore for the first time.
Overview
Founded in 2017, Sleek has grown into one of the larger corporate service providers in the region, reporting more than 450,000 incorporated companies across Singapore, Hong Kong, Australia, and the UK. It also holds a Major Payment Institution licence from the Monetary Authority of Singapore. This scale is notable given the firm is still relatively young compared to some traditional accounting practices that have operated for decades.
The MAS licence in particular signals a level of regulatory oversight that goes beyond what a typical accounting firm is required to hold, since it allows Sleek to handle payment-related services alongside its core incorporation and compliance work. For founders juggling multiple jurisdictions, this combination of regional presence and financial licensing can simplify cross-border banking and payment needs that would otherwise require a separate provider. It also gives the firm a broader base of client data and edge cases to draw on, which tends to show up in smoother onboarding for new company registrations.
Why We Selected Them
The single-platform approach is the differentiator. Rather than referring clients elsewhere for company registration or a registered address, Sleek keeps incorporation, compliance, and ongoing accounting under one roof, which reduces coordination gaps for busy founders.

Best For
Sleek is a good match for founders, including overseas entrepreneurs, who are setting up a Singapore company for the first time and want incorporation and ongoing compliance handled by the same team from day one.
Counto
Why We Ranked It
Counto stands out among the best accounting firms Singapore for its pricing model. Instead of charging by the hour or capping the number of transactions, Counto built its plans around unlimited transactions with pricing tied to business revenue, which gives SMEs more predictability.
Overview
Founded in 2019, Counto (formerly known as Xibo) is a Singapore-based fintech accounting firm that pairs AI-driven bookkeeping automation with a dedicated accounting team. Its tax system has reportedly achieved IRAS ASR+ Tier 3 accreditation, the highest tier of that accreditation in Singapore. Being a newer entrant, the firm has built its systems from the ground up around automation, rather than retrofitting older manual processes with new software.
This tier of tax accreditation matters in practice because it reflects a level of accuracy and integration with IRAS systems that not every provider has achieved, even among established players. For SMEs weighing up their options, this kind of technical accreditation can be a useful signal when comparing firms, since it points to a more rigorous back-end process rather than just marketing language. Combined with its dedicated account manager model, Counto has positioned itself as a fintech-first alternative to more traditional bookkeeping setups still common across Singapore.
Why We Selected Them
The combination of automation and a named point of contact is what makes Counto worth shortlisting. Clients get a dedicated Customer Success Manager reachable by phone or WhatsApp, rather than routing every question through a generic support inbox.

How to Choose the Right Accounting Firm in Singapore
Picking from the best accounting firms Singapore comes down to matching a provider’s strengths to your company’s actual needs, not just its marketing page.
Pricing
Ask for a full breakdown of what is included in the base plan, and what triggers additional charges. Some firms price by transaction volume, others by revenue tier, and the difference can matter a lot as your business scales.
Experience
A firm that has handled companies in your industry before will spot issues faster, whether that is inventory valuation for retail or revenue recognition for services businesses.
Reviews
Look beyond star ratings and read what specific problems clients mention, particularly around responsiveness during tax season and accuracy of filings.
Customer Support
Confirm how you will actually reach your accountant. A named contact who responds within a day is usually more useful than a general support email.
Location
While most accounting work today happens remotely, some founders still prefer a firm with a physical office they can visit, particularly for signing documents or discussing sensitive financial matters.
Specialisation
If you run an e-commerce store, a firm experienced with marketplace accounting will save you time. If you are incorporating for the first time, a firm strong in company registration will smooth that process.
Service Quality
Ask how errors are handled if they occur. A firm’s response to mistakes often says more about its reliability than its marketing claims.
Industry Reputation
Firms that are frequently mentioned across independent SME guides and comparison sites, rather than only in their own marketing, tend to have a more consistent track record.
Benefits of Choosing a Professional Accounting Firm in Singapore
Working with one of the best accounting firms Singapore brings real, measurable benefits beyond simply staying compliant.
Reduced Risk of Penalties
Late or incorrect filings with IRAS or ACRA can result in fines. A firm that tracks deadlines proactively reduces this risk considerably.
Better Financial Visibility
Proper bookkeeping means you actually know your cash position, not just at year-end, but month to month, which supports better decision-making.
Time Saved for Core Business Activities
Outsourcing bookkeeping and tax filing frees up hours that founders would otherwise spend reconciling receipts instead of serving customers or growing the business.
Access to Tax Planning Advice
Good accounting firms do more than file returns. They flag legitimate deductions, incentives, and reliefs that many business owners are unaware of.
Smoother Audit and Investor Readiness
Clean, consistent financial records make it far easier to pass an audit or satisfy investor due diligence when the time comes.
FAQs: Best Accounting Firms Singapore
What do the best accounting firms Singapore typically charge?
Pricing varies widely depending on transaction volume, revenue, and services included. Basic bookkeeping and tax filing packages for small companies often start in the low hundreds of dollars per month, while firms with revenue-based pricing scale their fees as your company grows.
Do I need an accounting firm if my company is very small?
Yes. Even dormant or small companies in Singapore must file annual returns with ACRA and, in most cases, submit tax filings to IRAS. An accounting firm ensures these deadlines are not missed, regardless of company size.
Can accounting firms in Singapore also handle company incorporation?
Many of the best accounting firms Singapore offer incorporation alongside accounting, which is useful for new founders who want registration, corporate secretarial support, and ongoing bookkeeping from a single provider.
How do I know if an accounting firm is reliable?
Look at how long the firm has operated, read independent reviews, and check whether they are transparent about pricing and processes upfront rather than only after you sign up.
Is cloud-based accounting better than traditional bookkeeping?
Cloud-based accounting generally offers more real-time visibility and fewer manual errors, since transactions sync automatically from bank feeds or sales platforms rather than being entered by hand.
Do accounting firms in Singapore handle GST filing?
Yes, most full-service accounting firms handle GST registration and periodic filing for companies that are GST-registered or approaching the mandatory registration threshold.
What is the difference between a bookkeeper and an accounting firm?
A bookkeeper typically records transactions, while an accounting firm usually offers a broader scope, including tax filing, financial statement preparation, and compliance advisory, often combining both functions.
Conclusion
Choosing among the best accounting firms Singapore ultimately depends on your company’s stage and priorities. Osome fits businesses that need strong e-commerce integration alongside human oversight. Sleek suits founders who want incorporation and ongoing compliance managed by one team from the start. Counto works well for companies that want predictable, revenue-based pricing with unlimited transactions.
None of these firms is a one-size-fits-all answer, which is exactly why comparing them against your own needs matters more than picking whichever name appears first in a search result. Take the time to request a quote, ask about their process for handling errors, and confirm how quickly they respond during tax season before committing.
If you are still weighing your options, reach out to a couple of these firms directly and compare how they respond. That conversation alone often tells you more than any review ever could.
