We have been a client of CYLL for over 20 years. We have very good working relationship. Byron and his team are super helpful and professional. Their work is thorough. They are approachable and offer constructive and helpful advice on issues raised by us. We are very pleased with their services and have referred our clients who require audit services to the team. I would not hesitate in recommending their services.

We’ve been working with this firm for the past 2/3 years. It’s been a great experience from the start. Byron and his team have consistently been professional, knowledgeable and responsive making what often perceived as a complicated process feel smooth and manageable. We highly recommend them if you’re looking for an accountant/ auditor you can trust.

We've been working with Byron and his team (Koei and Rosetta) for over a year now on company incorporations, annual renewals, and other corporate compliance matters, and everything has been going really well. What stands out the most is how quickly they get things done and how responsive they are whenever we have questions or need assistance. Their team is always easy to work with, and we can rely on them to keep things moving. Aside from these services, we also work closely with Kevin and Juno on audit and tax filings. One thing we really appreciate is how they always find ways to make it easier for both our teams to work together. Communication has been great, coordination has been straightforward, and they've been a reliable partner throughout our collaboration.

Excellent CPA. They provided top-tier support for our annual audit, tax filing, and offshore profits tax exemption. Professional, accurate, and highly communicative throughout the entire process. Know a lot about international tax regulations.

FAQ

Every audit engagement at CYLL is directly supervised and signed off by an in-house qualified Practicing CPA. We do not believe in the assembly-line model where files are passed entirely to unsupervised juniors. Instead, the exact size and seniority of your assigned audit team are designed to handle the technical complexities, transaction volumes, and structural requirements of your company.

Throughout the entire audit engagement, your team will have a direct line of communication with the engagement team lead, ensuring transparency from planning to final sign-off.

Our client base typically consists of three distinct corporate profiles:

High-Growth companies: Fast-growing companies that have outgrown small, sole-proprietor accounting firms or online service providers that outsource their audit work and now require institutional-grade support.

Mid-Market Corporations: Established organisations currently utilising Big 4 or second-tier regional firms who are looking for a high-touch service with transparency around fees and processing times.

We offer the same high level of technical expertise and regulatory experience as the largest international networks, but deliver it through a high-touch, CPA led experience with clarity around timelines and deliverables.

Multi-jurisdictional corporations: Companies that have entities spread across the APAC region looking for a cohesive client experience, and to have their audit handled by a single firm with teams in multiple regions.

The exact duration of an audit fluctuates depending on the complexity of your financial statements. However, we deliberately limit the types of clients we onboard to protect and maintain our capacity.

This deliberate client-to-partner ratio allows us to strictly adhere to agreed-upon timelines, and provide your management team with transparency regarding processing times.

We have eliminated the chaotic back-and-forth email loops and missing file trails that plague traditional audit workflows by using our in-house secure information request system.

Our centralised digital portal serves as the single source of truth for your entire audit documentation history. Both your internal finance team and our auditors can track exactly what evidence has been requested, what has been uploaded, and when it was received. By keeping all queries and working papers aggregated in one secure platform, we dramatically minimise operational friction and drastically reduce the number of request rounds.

Yes. CYLL is an established regional firm with an active presence across Hong Kong, Singapore, Malaysia, and Mainland China. Mid-market organisations operating across the APAC region choose us because we eliminate the fractured client experience of managing separate, unaligned service providers.

Partnering with us ensures that your cross-border reporting, consolidated financial statements, group audits, and regional tax compliance (such as offshore profits claims) are handled seamlessly under a single, unified regional umbrella.

Our audit quotations are fixed prior to the commencement of any audit work. All necessary disbursement costs are calculated and fully included into our initial quotations. Any unforeseen disbursement costs that arise during the course of an engagement is always first approved by the client.

Please reach out directly to our audit teams at info@cyllcpa.com. A senior member of our team will coordinate a brief discovery call to prepare your quotation.
