Living by our Values

Our Core Values

Integrity & Independence

We owe to ourselves and to our clients. Integrity is the cornerstone of our relationships within our organization, and with our clients and stakeholders. To gain and nurture trust, we must always be honest and straightforward.

Independence has always been  state of mind. Whether we work as auditors or advisors, acting independently is essential.

Responsibility & Stewardship

Sustainable firms are the ones that are accountable. We believe in responsibility, for our personal and professional conduct. We care about how our work may affect our communities and we seek to make a difference.

Continuity and stewardship are key ingredients of our long-term development and that of our clients.

Diversity & Respect

Our clients count on our talent and expertise. Our strength lies in our people. Respect for every individual and their unique contribution is part of who we are. We value differences and diversity, knowing that new perspectives make our organization fairer and stronger.

Technical excellence

In all our projects and assignments, providing the best possible service to our clients is our number one priority. Hence, we constantly pursue the highest level of technical excellence and quality in everything we do.

From Values to Behaviours: our Global Code of Conducts

Our global code of conduct is a practical guide to help our clients, regardless of age, position or country, to navigate difficult choices and make the right decisions, in line with our values. It clearly states who we are, what we expect from our clients and how we deal with our clients, stakeholders and communities at large.


We are here to help you succeed in your Business Life Cycle


Do you work with individual clients too, or just businesses?

We are glad to help with personal tax and accounting services as well. Many times we start with a business owner for business-related reasons and end up helping with them on their personal taxes/finances as well.

How does your fee structure work?

We do things a little different from some other firms (not to say their way is wrong!). Instead of charging an hourly rate, we typically charge a fixed price for most services which we believe gives us the incentive to deliver your desired results in an efficient and timely manner. During our initial call, we will be able to tell you a pretty accurate range you could expect to pay for services.

We charge lowest price in Sri Lanka for incorporation a Company as encouragement of investments in Sri Lanka.

Can I schedule an in-person meeting with you?

We always welcome the opportunity to meet face-to-face with our clients!

Do you prepare my taxes while I wait?

Our processes are setup so that you do not have to come into our office to share the information needed for us to prepare your taxes other than new clients. We setup a phone interview with each tax client and go through a questionnaire, then we send you an electronic request list that is tailored specifically to you. You will be able to easily share all answers and documents using your phone or computer.

Will you come out to our office to perform weekly/monthly accounting services?

This is typically not our process. In the spirit of operating efficiently, we have systems and processes in place that allow us to communicate and collect information from you remotely. However, if there are matters you feel need to be discussed in person, we are more than happy to meet you at your office or have you come to ours for a face-to-face meeting (this is assuming you are in the local Colombo and Gampaha area: for non-local clients, we can always get on a video call for face time).
