Osome vs Sleek vs Excellence Singapore: An Honest 2026 Comparison

By Lucas Seah, Founder of Excellence Singapore Group | Last Updated: October 2026

Here is the honest answer before the feature lists: Osome and Sleek differ less than most founders expect, and the choice that actually changes your next two years is not between the two platforms but between the platform model and a full-service firm. Both advertise local incorporation with a first-year secretary at S$600 all-in (published rates, October 2026), both run support through in-app chat because standardisation is what makes those prices possible, and both do genuinely good work for companies that fit the standard path. Most readers typing Osome vs Sleek into Google are already on one platform and feeling its edges. If that is you, the real question is whether your company still fits the model at all, and our CSP-registered company secretary team answers that question for incoming transfers every week. Not set on either platform and still choosing from scratch? Start with our full segment-by-segment comparison of incorporation services instead; this article is for the switch-or-stay decision.

Key Takeaways

• Osome and Sleek both advertise local incorporation plus a first-year secretary at S$600 all-in (published rates, October 2026), and that price buys a standardised app workflow rather than a named person who runs your file.
• Their secretary plans sit within S$50 of each other at entry: Osome publishes S$300 and S$600 a year, Sleek publishes S$350, S$500 and S$1,500 tiers. The gap that matters is not between the two brands but between the platform model and full-service.
• Accounting is where budgets diverge: Osome publishes revenue-tiered plans from S$898 per financial year for companies under S$30,000 revenue, Sleek publishes expense-tiered accounting plans from S$75 a month, billed annually, and both step up as the business grows.
• Year two is where entry pricing catches up: registered address renewals at S$300 a year, nominee director extensions once bundled months run out, and itemised add-ons such as XBRL filing.
• Switching away is routine: a board resolution, the incoming secretary’s consent and an ACRA filing, with no downtime for the company.
• A platform plan covers a dormant or very simple company; once you add staff, share changes or a nominee, one named team running your secretary, accounting and tax file saves time and the re-explaining.

How we built this comparison (and where we sit in it)

Excellence Singapore is the third name in this comparison, and we serve many of the same founders, so we have made every figure checkable: every Osome and Sleek figure below comes from their own published Singapore pricing pages, checked in October 2026 and dated in the text, and where a price is not published we say so rather than guessing. There are no links to either platform here, which is our standing editorial rule for commercial providers, and no affiliate relationships anywhere in this article. We also set out, in a dedicated section, which companies a platform plan fits and where full service adds more. The comparison covers the three things a switch-or-stay decision actually turns on: the published pricing ladder, what each model includes and excludes, and what year two looks like.

What Osome and Sleek genuinely do well

Credit first, because the platforms earned their market share. Both publish their prices, and published pricing is a real strength of the platform model even though what it prices is a standardised workflow rather than advice on your specific situation. Onboarding is fast and fully remote on both, which suits simple setups precisely because nothing about them needs a conversation. The apps handle routine work well: e-signing, document storage, filing reminders and standard resolutions move quickly when your company matches the template the software was built around. And the entry pricing is real: S$600 all-in for incorporation plus a first-year secretary is cheap by any measure, kept cheap by the same standardisation that becomes the constraint later. For the companies the model was designed for, it works; the rest of this article is about what happens when your company stops being one of them.

Osome and Sleek pricing in 2026: the published ladder

Government fees are identical whoever files: ACRA charges S$15 for the name application, S$300 for registration and S$60 per annual return, so every package below is service fees wrapped around the same government money. All platform figures are the providers’ own published rates as at October 2026; promotional prices move, so confirm the number on the day you buy.

Osome’s published Singapore plans (October 2026)

Osome’s local incorporation-plus-secretary package is S$600, shown against a S$950 list price, and includes the ACRA filing with the S$315 government fee, the constitution and post-incorporation documents, and a first-year secretary handled through in-app chat, with the annual return and its S$60 fee covered. A Full compliance package from S$1,472 adds first-year bookkeeping, unaudited financial statements, the ECI and the annual tax return for expected first-year revenue up to S$30,000. A registered address is a S$300-a-year add-on and CorpPass registration is S$100. Standalone secretary plans are S$300 a year (annual return and AGM) or S$600 with routine changes included. Accounting is priced by revenue tier: the entry Operate plan runs from S$75 a month, billed at S$898 per financial year, and applies to companies under S$30,000 in annual revenue; above that band the price climbs inside the live plans page, which is worth knowing before you model year two on the entry figure. Published extras include simplified XBRL at S$330, full XBRL at S$550 and urgent filing at S$750.

Sleek’s published Singapore plans (October 2026)

Sleek’s entry local plan, the Founder Launch Kit, is S$600, shown against a S$700 list price, including S$375 of government fees, the secretary appointment, annual return, AGM and unlimited routine company changes. The Compliance plan at S$1,600 adds year-one bookkeeping, annual financial statements, the tax return and an assigned accountant, and Full Compliance at S$2,000 adds a registered address with a digital mailroom. Standalone secretary tiers are published at S$350 a year (companies with up to 2 shareholders), S$500 (share work, up to 9 shareholders) and S$1,500 (complex share operations), with support SLAs of 72, 48 and 24 hours by tier, a useful reminder that on a platform the response time is itself a priced feature. For overseas founders, the foreigner Starter bundle is S$2,600 with accounting, corporate tax filing, a registered address and a nominee director included for 3 months, Full Compliance is S$4,000 with a 12-month nominee, and the visa variant is S$4,188 with Employment Pass support and a 6-month nominee. Sleek also publishes standalone accounting plans tiered by annual expenses: Annual Filing and Bookkeeping from S$75 a month, Accounting Essentials with monthly bookkeeping from S$90 a month and Accounting Premium from S$250 a month, each billed annually per financial year, with corporate tax filing included and GST as an add-on.

Excellence Singapore’s published figures (October 2026)

Our published prices sit on our own pages: incorporation from S$1,000 including the S$315 government fee and a named first-year secretary, and the nominee director service from S$2,000 per annum. Corporate secretary retainers are quoted to scope and sit within the S$550 to S$900 a year band we publish for SME full-service firms in our corporate secretary comparison; accounting starts from S$200 per month for monthly bookkeeping and is quoted on volume and complexity, and our accounting firm comparison shows the same segment logic across the market. A quote means the number you get is the number for your company, not a tier you grow out of mid-year. The other difference is memory: the same named team runs your secretary, accounting and tax file year after year, so you explain your company once.

Osome, Sleek and Excellence Singapore at three company profiles

Like-for-like pricing is hard across two different models, so here it is at three concrete profiles, using only published figures and saying quote-based where that is the truth.

For a dormant company, a platform’s entry plan covers the basics at the lowest published price; the picture changes once the company starts trading, a point we return to below. The foreign-founder row cuts the other way once you compare like periods: Sleek’s S$2,600 entry bundle covers the nominee for 3 months, while a full year of cover costs S$4,000 on its published plan, which also bundles accounting and a registered address, against roughly S$3,000 from us, combining incorporation from S$1,000 with the nominee at S$2,000 per annum, all October 2026 figures.

Where SMEs outgrow Osome and Sleek

The pattern repeats often enough to describe without pointing at anyone. It starts with support: chat-first service is a model characteristic, not a failing, but a queue that is perfectly adequate for a standard filing becomes painful the first time something urgent or unusual lands, because tickets do not know your history and SLAs are measured in hours, not in understanding. Switchers describe the same moment almost word for word: re-explaining the company’s history to a new chat agent for the third time, because in a queue-based model no single person owns your file. It continues with accounting: platform bookkeeping is standardised by design, so revenue tiers and add-on charges arrive exactly as your business gets more interesting, and founder forums repeat the same arc, liked at incorporation, outgrown at bookkeeping. It ends at the complexity ceiling: corporate shareholders, mid-year share transfers, a nominee arrangement that needs judgement, an Employment Pass running alongside a filing. None of that breaks a platform; it just queues. Our post on the signs you have outgrown a digital-first platform lists the tells, and the companion piece on why service level matters more than the software explains why the gap widens as a company ages.

Year two on Osome or Sleek: what the entry price does not include

The entry price is the cheapest either platform will ever be, which is not a criticism, it is the model: year one is priced to win the account and much of what follows is itemised. On Osome, the published lines stack like this as at October 2026: registered address at S$300 a year, CorpPass at S$100, simplified XBRL at S$330, full XBRL at S$550, urgent filing at S$750, and accounting that steps up by revenue tier once you pass the S$30,000 entry band. On Sleek, the Founder Launch Kit price is a promotional figure against a higher list, the registered address lives in the S$2,000 Full Compliance plan, secretary tiers step from S$350 to S$500 the moment share work appears or the shareholder count passes two, and the foreigner bundle’s 3-month nominee needs extending or upgrading toward the S$4,000 full-year plan. None of these lines is hidden; they are all published. That is exactly why the comparison that protects you is the 24-month total for what your company will actually need, not the checkout price.

What are the alternatives to Osome and Sleek?

There are four realistic alternatives, and they differ by model rather than by logo: another digital-first corporate service provider, a traditional accounting firm, a full-service local firm where a named accountant and an in-house tax team run your file, or keeping your own books on accounting software with a company secretary on a separate retainer. Whichever model you pick, the statutory work stays the same. ACRA requires a company secretary to be appointed within six months of registration, IRAS expects the Estimated Chargeable Income (ECI) within 3 months of the financial year end unless the company qualifies for a waiver, and the annual tax return, the annual return and, unless it is dispensed with, the AGM follow every year. So the useful comparison is who does each of those jobs and how each one is charged.

Another digital-first corporate service provider

Moving to a third platform keeps the model Osome and Sleek share: published plan tiers, remote onboarding and support through chat or email against a stated response time. It suits a company that is content with the model but wants a different price point or app. Check how the accounting plan is tiered, because the two platforms measure differently: Osome tiers its plans by annual revenue, while Sleek tiers its standalone plans, from S$75 a month billed annually, by annual expenses. Check whether GST sits inside the fee: Sleek describes GST as an add-on and lists quarterly GST filing at S$300 a quarter, while Osome lists GST return filing at S$1,200 a year on its Grow plan, outside its entry Operate plan. XBRL is itemised on both, at S$330 to S$550 a year on Osome and S$500 a year on Sleek (all checked October 2026). The cost structure is a subscription plus extras, so price the add-ons your company will actually use.

A traditional accounting firm

A conventional accounting practice usually prices by engagement: an annual fee for compiling the financial statements and filing the tax returns, quoted after the firm reviews your records. It suits a steady company that mainly needs year-end work and values a long relationship with one practitioner. Check whether bookkeeping is done monthly or once at year end, whether the fee covers the ECI and Form C-S as well as the accounts, and whether the company secretary, AGM documents and annual return sit with the same firm or with a separate provider. If your company needs a statutory audit, the audit is carried out by the audit firm you appoint, so ask how the accountant works with that firm at year end; our guide to statutory audit costs explains when an audit applies, and our accounting fees guide shows how engagement pricing is usually built.

A full-service local firm with a named accountant and in-house tax adviser

This is how Excellence Singapore works. A named accountant runs your monthly bookkeeping and year-end accounts, our in-house tax team, which brings accreditation from the Singapore Chartered Tax Professionals (SCTP) in both income tax and GST, prepares the ECI, Form C-S and GST returns, and our company secretary team handles the AGM, the annual return and any share changes, all on one file. It suits companies with growing transaction volumes, staff on payroll, share changes or a nominee arrangement, where one accountable team saves the re-explaining. Our accounting starts from S$200 per month for monthly bookkeeping and our payroll from S$30 per employee a month, with year-end IR8A filing and IR21 tax clearance charged separately per employee. Where an audit is required, we prepare the accounts and work with your appointed audit firm.

DIY bookkeeping on accounting software, plus a company secretary

Some founders keep their own books on accounting software such as Xero and retain a company secretary only for the statutory work. It suits a very small company with few transactions and a founder who is comfortable with bookkeeping and IRAS filing. Check which tax return you can file: IRAS allows Form C-S for companies with annual revenue of S$5 million or below, and the shorter Form C-S (Lite) at S$200,000 or below, provided the other conditions are met. Check who will prepare the financial statements and any XBRL filing, and whether the secretary’s retainer covers the AGM and the annual return. The cost structure is a software subscription plus a secretary retainer, with your own time as the line that never appears on an invoice; our accounting software comparison covers the setup side.

How to choose between them

Put the same five questions to every option, in writing, before you sign:

• Scope: what does the monthly or annual fee cover, line by line, and what is billed per change or per filing?
• Tax filings: who prepares and files the ECI, the Form C-S or Form C, and the GST returns once you are registered for GST, and is each one inside the fee?
• Year-end extras: how are IR8A forms for employees, XBRL financial statements, the AGM and the annual return charged?
• People and response times: is there one named contact who owns your file, and what response time is promised on each plan?
• Leaving: how are your statutory registers, ledgers and working papers handed over if you move, how much notice is required, and is there a fee for the handover?

If you are already on a platform and the answers point elsewhere, the next section covers how the switch works, and our guide to choosing a corporate secretary goes deeper on the secretarial side.

Leaving Osome or Sleek: how the switch actually works

The switch is administrative, not surgical, and your company keeps operating throughout. The incoming firm prepares a board resolution, the new corporate secretary consents to act, the appointment change is filed with ACRA, and your statutory registers, minutes and records are handed over. Accounting records were always your company’s property, so they move with you. Most handovers complete within days, and a competent incoming team does the chasing, not you. We keep a step-by-step transfer guide that walks through the resolution, the filings and the timeline, including the mid-year cases where an annual return is imminent.

Questions to ask before you move

• Who exactly handles my file, and do I get their direct line, or is support a shared queue?
• What is the response SLA in writing, and what counts as urgent?
• What does the retainer include, and what is billed per resolution or per change?
• How fast is the handover, and who chases the outgoing provider for the registers?
• Do you work with my books as they are, including Xero, or is there a migration cost?
• For nominee arrangements: what is the scope of authority, the deposit policy and the exit process?

When Osome or Sleek fits, and when full service adds more

A platform plan fits some companies well. If your company is dormant or close to it, a S$300 to S$350 published secretary plan covers the annual return and AGM (platform rates, October 2026). If you run a simple, fully local business with clean books, few transactions and no share changes on the horizon, the S$600 entry packages cover the standard path, and the apps are well built for founders who prefer self-serve. The platforms’ own published tiers show where that changes: S$1,500 secretary tiers and revenue-stepped accounting exist because non-standard work takes more time, whoever does it. That is where a full-service firm adds the most: one named team that already knows your secretary, accounting, tax and payroll file, a direct line instead of a queue, and changes scoped upfront rather than billed per click. Choose a platform while your company matches its template, and move to full service when it grows beyond it.

Foreign founders on Sleek: the nominee director math

Every Singapore company needs at least one locally resident director, and for overseas founders that requirement, not the software, decides the real cost of each route. Sleek’s published foreigner bundles as at October 2026: S$2,600 with the nominee director included for 3 months, S$4,000 with a 12-month nominee, and S$4,188 with Employment Pass support and a 6-month nominee. The month count is the number to check, because a nominee you still need in month four moves the entry bundle onto the full-year plan’s price ladder. Compare like periods: a full year of platform cover is S$4,000 on the published plan, which also bundles accounting and a registered address, while Excellence Singapore’s nominee director service is published at S$2,000 per annum, with incorporation from S$1,000 on top, roughly S$3,000 for the same year with a defined scope of authority, documented KYC and a refundable deposit whose terms sit in the engagement agreement. Osome also serves foreign founders: its foreigner plans, listed under a separate tab on its pricing page, start from S$2,438 with a nominee director for 3 months, S$3,772 with a 1-year nominee and S$3,822 with a 6-month nominee in its visa plan, as at October 2026, so confirm the number and the nominee period on the day you compare.

Frequently asked questions

What do Osome and Sleek do in Singapore?

Both are digital-first corporate service providers selling published plans to Singapore companies. Osome offers incorporation, company secretary, accounting and tax plans run through its app, with expert support via in-app chat. Sleek offers incorporation, corporate secretary, accounting and tax plans, a registered address with a digital mailroom and a business account, and states that it is a registered filing agent and corporate service provider authorised by ACRA. Both serve local and overseas founders remotely.

Is Osome a good company?

Osome is an established digital-first provider with clearly published prices, S$600 all-in for local incorporation plus a first-year secretary as at October 2026, and for companies that fit its standard workflows the service does what the price promises. The more useful question is model fit rather than brand quality: app-first support suits routine filings, while companies with share changes, rising revenue tiers or nominee needs tend to be better served by a full-service firm where one named team handles the whole file.

Is Sleek a good company?

Sleek is an established digital-first provider with published prices, S$600 for its entry local plan including government fees as at October 2026, and for companies that fit its standard workflows the service does what the plan describes. The more useful question is model fit rather than brand quality: app and email support against a tiered response time suits routine filings, while companies with share changes, growing books or nominee needs may prefer one named team handling the whole file.

Is Sleek or Osome better?

Neither wins outright, and the differences are smaller than the marketing suggests: both publish S$600 local entry packages, both run chat-first support, and both climb in price as complexity grows. Sleek publishes secretary tiers up to S$1,500 a year for complex share work, while Osome publishes revenue-tiered accounting from S$898 per financial year, all October 2026 rates. The sharper question is whether the platform model still fits your company at all, because a company that has outgrown one platform has usually outgrown both.

What are the alternatives to Osome and Sleek?

Think in models rather than brand lists. The alternatives are another digital platform, which changes the logo but keeps the model, a traditional accounting firm priced per engagement, a full-service local firm such as Excellence Singapore, where a named accountant, an in-house tax team and the company secretary work on one file, or DIY bookkeeping on accounting software with a separate company secretary. Standard and simple suits a platform; growing or non-standard suits full-service.

How much do Osome and Sleek cost in Singapore?

Published rates as at October 2026: both advertise local incorporation with a first-year secretary at S$600 all-in including government fees. Osome lists secretary plans at S$300 to S$600 a year and entry accounting at S$898 per financial year for revenue under S$30,000. Sleek lists secretary tiers at S$350 to S$1,500 a year, incorporation bundles up to S$2,000, and foreigner packages from S$2,600 with a 3-month nominee director. Add-ons such as a registered address at S$300 a year are extra.

How much do Osome and Sleek charge for accounting?

Published rates as at October 2026: Osome’s accounting plans start at S$75 a month, billed at S$898 per financial year, for annual revenue up to S$30,000, with higher tiers above that. Sleek’s standalone plans start at S$75 a month for annual bookkeeping, S$90 a month for monthly bookkeeping and S$250 a month for weekly bookkeeping, billed annually and tiered by annual expenses. XBRL filing is an extra on both, and GST filing sits outside both entry plans.

How do I switch away from Osome or Sleek?

The mechanics are simple and involve no downtime: your incoming provider prepares a board resolution appointing the new corporate secretary, the outgoing appointment ends, and the change is filed with ACRA, with your statutory registers and records handed over as part of the transfer. Most transfers complete within days, and accounting records belong to your company, so they move too. The practical work sits with the incoming firm, which is why choosing it carefully matters more than the exit itself.

Is a platform or a full-service firm better for my company?

Match the model to the company. A platform is the right buy for dormant or very simple companies on standard workflows at the lowest published price. A full-service firm adds the most value when the company generates judgement calls: share changes, growing transaction volumes, nominee arrangements, or anything where you want one accountable person rather than a ticket queue. The honest test is your last three support requests: if any of them needed a conversation, the model is the thing to change, not the platform.

Talk to Excellence Singapore before you renew

If a renewal notice is sitting in your inbox, run the year-two math above before paying it: the platform’s 24-month total for what your company now needs, against a quoted retainer from a firm where a named team already knows your file. Excellence Singapore has run that stack, secretary, accounting, tax and nominee, for 4,000+ businesses since 2013, and if your company is still a genuine fit for a platform we will say so rather than sell you a switch.
