- The Big Four are Deloitte, PwC, EY and KPMG. Their broad audit, tax, deals, risk and advisory capabilities suit listed, regulated and complex multinational businesses.
- Sleek is built around Hong Kong SMEs and startups. Its offer centres on bookkeeping, accounting, payroll, company secretarial work and tax compliance through a digital workflow.
- The pricing evidence differs. Sleek publishes fixed annual plan prices. Deloitte, PwC, EY and KPMG don’t publish standard Hong Kong SME rate cards, so a genuine Big Four comparison requires written proposals.
- A bigger firm isn’t automatically a better fit. The right provider depends on reporting complexity, stakeholders, service scope and how much specialist advice you need.
- Some businesses need both. An SME can use Sleek for bookkeeping and compliance while retaining another qualified firm for specialist or group-level work.
- Choose a Big Four firm: for listed, regulated, IPO, complex transaction or multinational group work
- Choose Sleek: for SME bookkeeping, accounting, payroll and Hong Kong compliance on published plans
- Compare the full annual cost: check whether bookkeeping, audit, tax filing, software, payroll and advisory are included
- Use both when needed: routine finance operations and specialist enterprise advice can sit with different providers
Sleek vs the Big Four in Hong Kong isn’t a quality contest between interchangeable firms. It is a fit decision. A listed group preparing an IPO needs a different team from a 20-person company that wants clean monthly books, payroll and its Profits Tax Return handled.
The useful question is not “Which name is bigger?” It is “Which service model matches the work my business actually has?”
In this guide, you’ll learn:
- What the Big Four and Sleek each provide
- How the service and pricing models differ
- Which provider fits specific business scenarios
- How to compare proposals or switch providers
Should you choose Sleek or a Big Four firm?
Choose based on business complexity, reporting stakeholders and the work in scope.
A Big Four firm is usually the stronger fit when your company is:
- Listed, or preparing for capital markets
- Heavily regulated
- Coordinating technically complex work across many jurisdictions
Sleek is usually the closer fit when you’re a Hong Kong SME that wants:
- Recurring bookkeeping, management reporting and payroll
- Local compliance handled
- Published plan prices and one digital workspace
Neither answer is universal. Big Four firms serve private businesses too, and some SMEs have specialist needs that justify one. Sleek supports growing companies, but isn’t built to replace enterprise capital-markets, deals or regulatory advisory teams.
Who are the Big Four accounting firms?
The Big Four are Deloitte, PwC, EY and KPMG, four global professional-services networks.
Their Hong Kong practices provide combinations of:
- Audit and assurance
- Domestic and international tax
- Deals, transaction and valuation support
- Risk, controls and regulatory work
- Consulting and technology transformation
- Capital-markets and IPO services
The exact service, engagement team and legal entity differ by firm. Treat “Big Four” as a market category, not one provider with one price list.
“Big Four” isn't a legal or regulatory designation. Deloitte, PwC, EY and KPMG are separate networks, and engagements are contracted with the relevant member firm. Compare the actual Hong Kong proposal and engagement letter, not the category name.
What are Big Four firms best suited to?
Big Four firms are best suited to work where scale, specialist depth or external stakeholder expectations drive the decision.
Common examples include:
- Listed-company and capital-markets reporting
- IPO readiness and reporting-accountant work
- Regulated financial-services engagements
- Large multinational or multi-GAAP audits
- Complex M&A, valuation, restructuring or due diligence
- Multi-country tax, transfer pricing and controversy
- Enterprise risk, controls and transformation projects
Their advantage is access to large, multidisciplinary teams and international networks. That depth may be necessary even when it costs more to scope and coordinate than ordinary SME compliance.
What does Sleek provide in Hong Kong?
Sleek provides recurring corporate and finance support for Hong Kong SMEs.
Its current service range includes:
- Annual or monthly bookkeeping
- Unaudited financial statements and management reports
- Payroll and MPF on eligible plans
- Employer’s Returns and Profits Tax support
- Company incorporation and company secretary services
- Audit and tax-filing coordination through qualified Hong Kong audit partners
- Offshore Profits Tax claim support on Premium plan
SleekBooks is included in the accounting plans, while Xero is included on Premium. Clients work with a named accountant or bookkeeper, with service response targets set by plan.
How do Sleek and the Big Four compare?

How do the pricing models differ?
Sleek publishes our annual starting prices up front. The Big Four price each job through a proposal instead, and the fees scale based on project scope, company size, and transaction volume, with hourly rates for senior associates and managers typically ranging from HK$1,500 to HK$4,000+.
| Annual work | Sleek published starting price | Deloitte, PwC, EY, KPMG | What must match |
|---|---|---|---|
| Annual bookkeeping and reporting | HK$3,500/fy | Proposal required | Transaction band, financial statements, Employer’s Return |
| Monthly books, reporting and payroll | HK$5,880/fy | Proposal required | Payroll headcount, MPF work, reports, response target |
| Weekly books, senior reviews and Xero | HK$15,120/fy | Proposal required | Review frequency, software licence, support |
| Standard SME audit and BIR51 filing | HK$5,500/fy | Proposal required | Audit, tax computation, BIR51, financial statements |
| Premium audit with offshore claim support | HK$8,000/fy list price | Proposal required | Offshore claim scope, complex assets, IRD follow-up |

What would a Sleek annual service stack cost?
For a company in the lowest expense band, our published list prices produce these examples:
| Example scope | Calculation | Published annual total |
|---|---|---|
| Annual books + Standard audit and tax filing | HK$3,500 + HK$5,500 | HK$9,000 |
| Monthly books and payroll + Standard audit and tax filing | HK$5,880 + HK$5,500 | HK$11,380 |
| Premium accounting + Premium audit | HK$15,120 + HK$8,000 | HK$23,120 |
These are arithmetic examples, not quotes. They exclude company secretary, registered address, catch-up bookkeeping, and any work outside the stated plan. Expense bands, business activity, assets and tax position can all change the final scope.
What does the wider Hong Kong audit market charge?
Independent 2025/26 market research puts typical audit-only fees in these bands:
| Company profile | Typical annual audit fee |
|---|---|
| Very small private company with minimal transactions | HK$8,000–HK$15,000 |
| Small SME with moderate volume and a straightforward structure | HK$15,000–HK$30,000 |
| Mid-sized company with more volume, currencies or subsidiaries | HK$30,000–HK$80,000 |
| Complex, regulated, listed or near-listed business | HK$80,000–HK$200,000+ |
These are market benchmarks, not quotes from the Big Four. They’re also usually audit-only, whereas our published audit package includes Profits Tax calculation and filing. That’s why a headline fee range isn’t a like-for-like comparison.
To compare real proposals, send every provider the same fact pack and ask for:
- Included deliverables: bookkeeping, financial statements, audit, tax computation, BIR51 and advisory
- Pricing basis: fixed fee, time-based fee or capped estimate
- Assumptions: transaction volume, entities, currencies, inventory and reporting framework
- Extras: software, payroll, disbursements, catch-up work and IRD questions
- Team: contracting entity, engagement lead, specialists and expected timetable
The cost of an accountant in Hong Kong explains the other variables that can move a quote.
A capped estimate isn't the same as a fixed fee. Ask which events can reopen the price and whether software, technology charges, travel or other disbursements sit outside the cap. Require written approval before extra work starts.
Which provider fits your situation?
The likely fit becomes clearer when you match the provider to a specific job.

Big Four or capital-markets specialist |
Stakeholder expectations and reporting-accountant work can drive the appointment |
|
Bank, insurer or other heavily regulated group |
Big Four or sector specialist |

|
Multi-country group audit or complex transaction |
Big Four |
A coordinated network and specialist teams may justify the larger engagement |
|
SME with one difficult tax or deal issue |
Both may be useful |
Keep routine work separate from the specialist project |
|
Board, lender or parent names an acceptable auditor |
Provider on the approved list |
The stakeholder requirement controls the decision |
Don’t choose a smaller scope purely to reduce the fee when a regulator, investor, lender or technical issue requires specialist depth. Equally, an ordinary SME should not pay for an enterprise team it will not use.

Can you use Sleek and a Big Four firm together?
Yes. Many businesses split the work: recurring finance operations go to one provider, specialist or group-level engagements to another.
A common split:
- Sleek handles the day-to-day — Hong Kong books, payroll and local compliance
- The Big Four firm handles the specialist work — transfer pricing, a transaction, or regulatory advice for the parent group
Two things to lock down before you start:
- Check audit independence and information-sharing rules for the specific engagement.
- Set responsibilities in writing. Decide who owns the ledger, prepares financial statements, answers audit requests, files BIR51, and handles technical positions.
Two capable providers can still leave gaps if each assumes the other owns a task.
Don't let the company depend on one BTP Administrator. If every administrator leaves, the Responsible Person must appoint replacements, and the business account can be suspended while the IRD verifies the change. Keep at least two active administrators where practical.
How do you switch your accounting to Sleek?
Switch by agreeing scope, collecting the existing records and setting a clean handover date.
Sleek’s migration process is:
- Share your latest financial statements, ledgers and compliance deadlines
- Confirm the plan, reporting cadence and services in scope
- Let the migration manager coordinate records with the current accountant
- Move the bookkeeping data into SleekBooks or the agreed system
- Reconcile opening balances and continue the compliance calendar
Most migrations complete in two to three weeks. Complex or incomplete records can take longer, so don’t wait until the Profits Tax deadline.

FAQs about Sleek vs the Big Four in Hong Kong
No. Hong Kong law doesn’t require a Big Four brand for an ordinary private-company statutory audit. The audit must be performed by an appropriately qualified independent Hong Kong auditor. Check the practice on the AFRC public register. A lender, investor, regulator or parent company may set stricter commercial requirements.
Sometimes, but the auditor must remain independent and management must keep responsibility for the accounts. The permitted setup depends on the services, safeguards and applicable ethical requirements. Ask who prepares the ledger and audited financial statements, who makes accounting decisions and which independent practice signs the report.
No. A provider change doesn’t reset the company’s Profits Tax Return, Employer’s Return or statutory deadlines. Build the handover plan around the existing calendar. Leave time for opening-balance checks, unresolved tax questions and prior-year audit records, particularly if the change happens close to a filing date.
The company should retain suitable administrator access and the ability to export its records. Confirm access rights for directors, finance staff, the accountant and auditor before signing. Also check what happens to documents, reports and transaction data after termination. A clean export reduces dependence on any one provider.
The scope should be repriced or split before service quality suffers. More entities, regulated activity, consolidation, complex instruments or capital-markets work may need a specialist or larger firm. The routine Hong Kong books can sometimes stay with an SME provider while another team handles the complex engagement.
Not automatically. The parent company’s group auditor decides how component work will be performed and reviewed. It may use a Hong Kong component auditor, require a network firm or perform additional procedures itself. Confirm the group instructions before appointing the local auditor, because changing later can duplicate work and cost.
