Business owners don’t dream about VAT returns or deadlines. They dream about freedom - to build something meaningful, do work they care about, and know their numbers are handled properly.
I started Top Tier Accounting because I believe great accounting should give you that freedom back - not take it away.
We operate virtually, partnering with clients nationwide. With roots in Dublin and Wexford, we bring local expertise and responsive online support - wherever your business is based.
I’m Brendan O’Brien, ACA, founder of Top Tier Accounting, a modern, tech-enabled practice serving ambitious businesses across Ireland.

I studied Business and Computer Science in college - a mix that shaped how I think: structured, analytical, and always searching for smarter ways to solve problems.
After graduating, I spent five years in practice perfecting my craft and qualifying as a Chartered Accountant (ACA).
After qualifying, I worked as a consultant - running my own small accounting setup while travelling the world and deepening my expertise in tax and professional practice as I began my Chartered Tax Adviser (CTA) exams.
Those years taught me how the right systems can turn a traditional office-based role into one that offers true independence and freedom - and how that same innovation can empower business owners to work smarter, with clarity and confidence.
Later, I spent 18 months in industry, gaining insight into how larger organisations operate.
But it also reaffirmed something important: my real passion is working directly with business owners - helping them cut through the noise, stay compliant, and grow with clarity and confidence.
During that time, I continued progressing through my Chartered Tax Adviser (CTA) qualification and invested heavily in learning - tax, technology, and smarter systems.

Those lessons became the foundation of Top Tier Accounting - a practice built on clarity, proactive support, and genuine care for the people we work with.
“Most business owners don’t want a new accountant - they want things done on time, their numbers explained clearly, and no unexpected letters from Revenue.”
That’s the minimum standard we hold ourselves to - the baseline every client can expect.
