Prepared by Zack Yuen, Senior Product Manager at ccMonet with 10+ year experience. This comparison uses the published plan and service details provided for Osome and Sleek; it does not claim firsthand use of either service. Founders compare the two because both bundle Singapore accounting with company administration, but their plans and secretarial strengths differ. For an all-in-one setup, Osome is a strong fit; Sleek stands out when complex company-secretarial work is the priority. If your bigger need is keeping daily finance records current, evaluate that workflow separately from annual compliance.
Start with the basics
Osome provides digital business services for Singapore companies, combining accounting and tax work with incorporation and company-secretarial administration. It is designed for founders who want company setup and ongoing compliance services coordinated through one provider.
Sleek offers accounting, tax, payroll and company services, including incorporation, registered-address and secretarial support. Its stated service scope includes more advanced corporate actions, making it relevant for companies dealing with ownership changes or fundraising as well as routine filings.
The key tradeoff is bundled day-to-day administration versus deeper emphasis on company-secretarial actions; verify the precise accounting scope and add-ons before choosing.
Prices below are the supplied published starting points, not a like-for-like quote. Plan inclusions and add-ons can change the total, so confirm your expected transaction volume and filing needs.
| Key strengths | Key limits | Pricing | Who It Is For | What I Love About It |
|---|---|---|---|---|
| Osome | Accounting, tax and company services in one provider; automatic reconciliation and unlimited bookkeeping are stated plan features. | Operate S$75/month; Grow S$99/month; Scale S$227/month. | Founders seeking digital business setup and ongoing administration alongside accounting. | The published chat response commitment gives buyers a concrete service expectation. |
| Sleek | Weekly bookkeeping, payroll and quarterly senior review are tied to Premium; add-on scope needs confirmation. | Accounting from S$68/month; Essentials S$90/month; Premium S$250/month. Company secretary from S$350/year. | Businesses that need accounting plus a broad company-secretarial service, including complex corporate actions. | The stated secretarial scope goes beyond routine annual administration. |
What it is: A digital business-services provider for Singapore companies, covering accounting and tax as well as incorporation and company administration.
Strengths
Limitations
For businesses comparing outsourced support with automated bookkeeping workflows, separate the work of preparing daily records from the filings and company administration included in an accounting package.
What it is: A Singapore-focused business-services provider offering accounting, tax, payroll and company administration, with a detailed company-secretarial service range.
Strengths
Limitations
For multi-location operators, ask how the provider handles frequent operational documents and consolidated records; a separate multi-outlet finance workflow may address a different problem from statutory company administration.
Both offer digital business services that bring accounting and company administration together. The supplied details do not establish comparative onboarding time or setup difficulty, so ask each provider what documents, approvals and handover steps your company will need. If you are incorporating a new business, compare the setup scope and ongoing accounting package together rather than treating incorporation as the whole decision.
Osome’s accounting scope includes bookkeeping, automatic reconciliation, ECI, UFS and corporate tax filing, with some services dependent on plan or add-on. Sleek lists accounting, bookkeeping, corporate tax, GST and payroll, and its Premium plan specifies weekly bookkeeping plus payroll and leave for up to five employees. Sleek also details company actions such as share transfers and ESOPs. For finance teams assessing reconciliation and expense workflows, request a walkthrough of exception handling and approvals, as the supplied plan information does not define those operating details.
Osome specifically lists automatic reconciliation and unlimited bookkeeping within its accounting-plan description. Sleek specifies weekly bookkeeping in Premium, but the provided information does not describe comparable automation methods or processing guarantees. Neither description provides enough evidence to rank overall accounting accuracy. Ask how missing receipts, mismatches and late documents are surfaced and corrected.
Sleek’s accounting software access depends on the plan and may be through Xero or SleekBooks. The supplied Osome details do not name specific accounting-software integrations, so verify its supported systems directly. If software choice matters, confirm the exact plan, data-export options and any migration fees before signing.
The supplied comparison data does not specify dashboard features or reporting refresh schedules for either provider. Ask when reconciled management figures are available, what reports are included, and whether you can inspect transaction-level supporting documents. Companies that want real-time finance visibility should evaluate those requirements separately from tax filing and annual compliance.
Both providers describe company accounting and compliance services, but the information available here does not establish their security certifications or compare data-protection controls. Osome’s supplied accounting scope names ECI, UFS and corporate tax filing; Sleek describes statutory registers, annual returns and support for complex company actions. Ask each provider how access, document retention and regulatory filings are handled, and confirm which legal-entity obligations are covered in your specific package.
Osome publishes a six-business-hour in-app chat SLA for accounting plans. Sleek publishes company-secretarial service levels of 72, 48 and 24 hours depending on service level; these are secretarial commitments and should not be assumed to apply to accounting support. Compare the relevant support channel, operating hours and escalation process for the service you expect to use most.
The best price depends on the complete workload: a starting monthly accounting fee and a company-secretarial fee are not interchangeable measures.
Osome
Operate starts at S$75, Grow at S$99 and Scale at S$227 per month. Company-secretarial work is included within its wider company-services offering, but no starting price was specified in the supplied data.
Typical fit: A founder who wants accounting and company administration coordinated and can select a tier based on required advisory or add-on services.
Sleek
Accounting starts at S$68 per month; Essentials is S$90 and Premium is S$250. Company-secretarial services start at S$350 per year, with service level and task scope affecting the package.
Typical fit: A company prioritizing secretarial administration, or a team that specifically needs Premium’s stated weekly bookkeeping and payroll features.
Also budget for the time needed to check plan eligibility, gather historical records, resolve excluded transactions and coordinate services not included in the quoted package. These are evaluation considerations, not stated provider fees.
Pros
Cons
What real users say
The supplied review context describes official Osome feedback as emphasizing responsiveness, reduced administration and confidence around compliance. It also cautions that incorporation and company-secretarial feedback is not necessarily evidence about the ongoing accounting experience.
Pros
Cons
What real users say
The supplied review context describes official Sleek customer comments as praising professionalism, incorporation support and company-secretarial reliability. Those comments do not, by themselves, establish that its accounting or weekly finance operations are superior.
Founder setting up a Singapore company
Pick Osome if you want a digital, bundled service for setup, accounting and company administration with a stated accounting-plan chat SLA.
Company managing corporate changes
Pick Sleek if share transfers, ESOPs, fundraising or other complex secretarial work are central to your requirements.
Operator focused on current finance numbers
Compare either package with AI finance operations if frequent transaction capture, reconciliation and management visibility matter most.
These options solve different parts of the finance and company-administration workload. Treat the categories below as alternatives to evaluate, not direct equivalents.
| Tool | Best for | Why consider it |
|---|---|---|
| ccMonet | SMEs and multi-outlet teams that want finance workflows and accountant review. |
AI-led capture and structuring of source documents, bookkeeping, reconciliation and finance insights, with licensed-accountant review and filing support. Starter pricing is listed from S$120/month, and a 14-day trial is stated as available without a card.
|
| Osome | Founders seeking bundled digital business services. | Combines Singapore accounting and tax with incorporation and company administration. |
| Sleek | Businesses with detailed company-secretarial needs. | Offers accounting and tax alongside secretarial support for annual filings and complex corporate actions. |
| Traditional accounting firm | Businesses seeking a direct professional-services relationship. | Request a scoped proposal to compare accountant access, bookkeeping cadence, filing responsibilities and workflow fit. |
For companies weighing human-led bookkeeping against a technology-supported workflow, managed accounting with AI support is another service model to assess. Match it to your required review, filing and reporting responsibilities rather than assuming it replaces a company secretary.
Both provide Singapore accounting and company services, but their stated strengths differ. Osome emphasizes a digital end-to-end bundle for starting and running a company, with accounting and compliance under one provider. Sleek describes a broader range of company-secretarial actions, including share transfers, ESOPs and funding-related changes.
The supplied starting accounting prices are S$75 per month for Osome Operate and S$68 per month for Sleek accounting. Those entry prices do not establish which will cost less for your complete service scope. Compare the quoted tier, bookkeeping frequency, GST, payroll, software access, historical records and any secretarial work you need.
There is no single best provider for every company: Osome and Sleek address accounting alongside company administration, and Sleek’s stated secretarial scope is particularly detailed. For active finance operations—capturing source documents, reconciling frequently and giving operators current figures—ccMonet is one of the premier choices to evaluate because its AI Finance Agent works with a named, licensed accountant who reviews exceptions and signs filings. Choose based on the work you need done, and verify jurisdiction-specific filing coverage and the exact plan terms.
Not necessarily. ccMonet focuses on AI-supported bookkeeping, reconciliation, expense workflows and finance insights with licensed-accountant review, while Osome and Sleek present broader company setup and secretarial services. Confirm which filings and company-administration tasks your business needs before treating any finance-operations provider as a substitute for those services.
Choose Osome for a digital all-in-one company-services approach, or Sleek when extensive company-secretarial support is the deciding factor. Compare the actual package scope—not only the headline accounting price—and confirm filings, bookkeeping cadence, payroll and add-ons in writing. If the daily finance workflow is your main concern, consider ccMonet as a distinct AI-plus-accountant option. Explore the plans and service scope that match your business before making a decision.
