Sleek vs Osome: Hong Kong Company Registration Service Comparison [2025]

Did you know that more than 84,000 companies were incorporated in Hong Kong in the first half of 2025 alone? And if you’re looking to join them, picking the right partner for your company setup is a critical first step.

Sleek and Osome are two of the most visible names in the market, offering online company registration with bundled secretarial, accounting, and tax services. But how do their packages, pricing, and service levels really compare?

At Statrys, we offer company incorporation services too, alongside business accounts and ongoing company secretary support, so we know what to look for. And we know that what looks like a simple setup today can become a hassle if the fine print isn’t clear.

In this article, we’ll give you a side-by-side comparison of Sleek and Osome:
✅ What you get (and don’t) with each package
✅ Pricing structures and hidden fees
✅ Service scope for company secretary, address, and business account support
✅ When either provider might (or might not) be the right fit

And if you're looking for a single provider that offers company registration and a business account under one roof — keep reading. We’ve included how Statrys compares, too.

In this section, we’ll look at the core company setup services, what’s offered under company secretary duties, how they assist with business accounts, and whether they bundle in accounting, audit, or tax services.

Let’s break down the must-have services and how they’re bundled in each package.

Both Sleek and Osome manage the full Hong Kong company registration process, from checking the company name to preparing and submitting the application. Once approved, you’ll receive the official documents issued by the Companies Registry and the Inland Revenue Department.

One key difference is how they handle the registered address, which is a legal requirement in Hong Kong. All company registration service providers in Hong Kong usually offer a registered address. The main difference is whether they charge for it as an add-on or if it's automatically included in the package. For example:

• Sleek offers it as a paid add-on (HKD 2,000 /year)
• Osome includes it only in the Comprehensive package. Otherwise, they charge an additional HKD 3,000 /year.

If you already have a registered address in Hong Kong, it is cheaper to choose Sleek's Starter package because the registered address is not provided.

In Hong Kong, you must have a Hong Kong company secretary who is either a local resident or a licensed Hong Kong Trust and Corporate Service Provider (TCSP) to stay compliant. Unless you have an in-house secretary, you’ll need a third-party provider to handle ongoing compliance.

Both Sleek and Osome offer tiered company secretary services. The basic tiers cover the legal requirements, while the higher tiers include extra features to support ongoing changes and admin tasks.

Here’s a comparison of their company secretary services.

If you expect to make changes to your company, such as updating directors, modifying business activities, or adjusting shareholding, within the next 12 to 24 months, Sleek is a better choice.

It includes a wider range of post-incorporation services across all plans, including statutory register maintenance and changes to company details. This ensures predictable support without surprise add-ons.

Osome restricts these services to its top-tier plan, making it less cost-effective unless share management is your priority. For most businesses, the lack of built-in post-incorporation support at lower tiers means higher costs down the line.

Sleek includes bookkeeping and accounting services in both the Compliance and Full Compliance plans. These cover bookkeeping and employer returns. However, audited financial statements, profit tax filing and offshore tax arrangements are only available in the Full Compliance package.

Osome, by contrast, offers these services as paid add-ons. Clients need to subscribe to a separate plan starting from HKD 292/month, and the cost increases if annual revenue exceeds HKD 200,000.

Sleek is a better fit for businesses looking for bundled bookkeeping with the option to upgrade to full audit and tax support. Osome may suit small businesses with minimal accounting needs, but costs can rise quickly as your revenue grows.

Neither provider offers a business account on their own platform, but both assist with opening one with other providers. Let’s compare:

Osome partners with multiple banks and fintechs, which gives clients more choice and can improve the chances of approval. Sleek, by contrast, partners primarily with Airwallex. This may work well for clients who already prefer Airwallex, but it limits flexibility for those with specific banking requirements.

Both Sleek and Osome packages, like most company incorporation providers, include a one-time fee that covers the incorporation service, the first year of company secretary, and the first year of registered address (if provided).

After the first year, you won’t pay the incorporation fee again, since the company is already established. However, if you continue to use the company secretary or registered address services, annual fees will apply for these ongoing services.

Here’s the comparison of those fees:

For founders who need a registered address and want everything bundled upfront, Osome’s Comprehensive package offers better overall value.

Sleek may be a better fit for those who prefer a modular setup or already have a registered address in place, as you can customise services you need.

Below is how their customer service compares.

Sleek offers more structured support with defined contact hours and separate lines for new and existing clients, which is likely a better fit for those who prefer human-led assistance.

Osome provides more digital contact options, including an AI-powered chatbot, which may appeal to those who are comfortable with automated tools and prefer quick, self-guided help without waiting for business hours.

Both Sleek and Osome offer a fast and remote-friendly registration process, with applications that take just a few minutes to complete.

The key difference lies in accessibility. Sleek lets you build your package and proceed to checkout without creating an account, which makes it easier to explore your options upfront. Osome, on the other hand, requires you to sign up with your name, email, and phone number before viewing full pricing.

Both Sleek and Osome are reliable options for setting up a company in Hong Kong, but they serve slightly different needs depending on your priorities.

• Founders who already have a registered Hong Kong address and don’t want to pay for bundled services they won’t use
• Entrepreneurs who prefer a modular setup, with control over which services to include (e.g. secretary, address, accounting)
• Business owners who want Airwallex business account application support.

• First-time founders who prefer an all-in-one solution, with a registered address and secretary service bundled
• Entrepreneurs who plan to start small and don’t need extensive accounting or audit support yet.

If you’re after clearer service terms or a truly all-in-one solution with a cost-effective price tag, you should consider Statrys.

With Statrys, you get a fully transparent company registration package that includes:

• A registered Hong Kong address
• Full company secretary services
• Clear, upfront pricing with no hidden charges, and
• In-house business account service

This means you are not being directed to another payment service provider or a bank to apply for an account, so the transition from registration to business account opening can be more integrated.

All it takes is a short online form, and we’ll handle the rest.
