Trustpilot - 1.3 / 5 from 170 reviews
This is a very low score, but it’s not unusual for global firms like EY on consumer review platforms. Many of the reviews come from individuals, job applicants, or smaller businesses who found it difficult to access personalised support. EY primarily serves large corporations, not the typical users who leave reviews on platforms like Trustpilot.
Glassdoor - 3.5 / 5 from 1,375 reviews
This rating reflects employee satisfaction and is considered average. Reviewers often praise the learning environment and global exposure, though many note long hours and high-pressure workloads.

Reviews
Trustpilot - 1.3 / 5 from 203 reviews
Deloitte also has a low score on Trustpilot, but the context matters. Most reviews come from individuals with limited interactions, such as those seeking personal support, which does not reflect the experience of Deloitte’s core corporate clients. Given the firm’s global scale, the relatively low number of reviews further suggests that Trustpilot is not a representative platform for evaluating a large professional services firm.
Glassdoor - 3.2 / 5 from 1,073 reviews
A score of 3.2 is on the lower side for a firm of Deloitte’s size. It suggests a varied employee experience, with some valuing the brand and career development opportunities, while others report challenges with workload and work-life balance.

Glassdoor - 3.6 / 5 from 825 reviews
This score suggests a generally positive employee experience. Reviewers often highlight the firm's strong training, brand reputation, and exposure to major clients. However, long hours and slow promotion are common concerns.

Audit Requirements in Hong Kong
In Hong Kong, all companies (except a few exempt types) must maintain proper books of accounts and prepare audited financial statements each year.
These statements are submitted to the Inland Revenue Department (IRD) as part of the company’s Profits Tax Return (PTR) and are critical for tax compliance, especially if you are claiming offshore tax exemption.
Here are the key points you should know:
Auditor must be a Certified CPA
The audit must be done by a Hong Kong CPA who holds a valid practising certificate from the HKICPA.
Audit reports are needed for tax filing
Your audited statements are submitted with your annual PTR to the IRD.
Some companies qualify for exemptions
An audit is not required if your company meets any of these conditions:
- Dormant (no business activity during the year)
- A branch of a foreign company already audited overseas
- A “small private company” that meets the threshold (e.g. revenue and total assets under HKD 100 million) under the Companies Ordinance

Indonesia is Southeast Asia’s largest economy, with a projected GDP of USD 1.43 trillion in 2025 and a population of over 285 million. With a rapidly expanding digital economy and strong growth in sectors like ecommerce, fintech, manufacturing, and logistics, it continues to draw attention from global entrepreneurs and foreign investors.
But opportunity comes with complexity.
Despite reforms like the OSS (Online Single Submission) system and a Positive Investment List that opens certain sectors to foreign ownership, Indonesia remains a challenging jurisdiction for first-time entrants. High minimum capital requirements, sector-specific restrictions, and bureaucratic inconsistencies can create friction for SMEs or startups used to more flexible markets.
In this guide, we’ll walk you through how to open a company in Indonesia and lay out the legal options, requirements, and practical realities, so you can make a decision based on your business goals and risk tolerance.
Tips for Choosing the Right Audit Firm
Most top audit firms in Hong Kong offer a solid level of quality and compliance. But for SMEs, especially mid-sized or growing businesses, the real value lies in finding a partner that matches your operational needs, not just one that ticks the audit box.
Here’s what to look for:
1. Relevant industry experience
Choose a firm that understands your sector and company size. For example, firms like BDO and SW CPA focus on industries like manufacturing and professional services, while RSM and Forvis Mazars offer strong mid-market expertise with international reporting.
2. Clear communication
A good audit firm will proactively outline timelines, document requests, and expected deliverables. Firms such as Baker Tilly and Grant Thornton are noted for their hands-on client support.
3. Transparent pricing
Most providers offer quote-based pricing. For SMEs, some may provide fixed-fee packages. It is always worth requesting a detailed breakdown of what is included.
4. Scalability for future needs
If your business is expanding or preparing for an IPO, firms like RSM and Grant Thornton offer services such as reporting accountant support and IPO audits to match your growth.
5. Value-added services
Some audit firms also offer tax advisory, sustainability reporting, or digital accounting tools. For example, Forvis Mazars provides ESG reporting, while others like Baker Tilly support broader compliance and advisory needs.
Taking the time to assess these factors helps ensure you choose an audit partner who can grow with your business and keep your financial reporting on track.
Make Audits Easier with a Statrys Business Account

With a Statrys Business Account, you’ll stay one step ahead of your audit by:
✅ Keeping business and personal transactions separate for clearer bookkeeping
✅ Automating reconciliation through integration with Xero
✅ Tracking international payments in real-time with SWIFT payment tracking and approval workflows
✅ Managing multi-currency transactions across HKD, RMB, USD, EUR, and more — no spreadsheets needed
✅ Sending and receiving local payments instantly via FPS
✅ Accessing full transaction history with user role controls for better visibility and compliance
FAQs
Do all companies in Hong Kong need to appoint an audit firm?
Yes, all companies incorporated in Hong Kong are required to prepare audited financial statements annually, which must be signed by an external certified public accountant (CPA) holding a valid practising certificate.
