About us

Our History

In 1992, having worked with a number of SMEs after qualifying as a Chartered Accountant, Gerry McNally established his own Chartered Accountancy practice providing the traditional range of accounting services (audit, accounting, taxation, company secretarial) to his client base. Always conscious that the traditional accountancy model had to evolve, his focus moved to the provision of outsourced management accounting services. In 1999, Kieran O’Brien joined the practice. The focus continued to be outsourced services and with technological developments, the outsourced accounting service became the core business.

In December 2008, we moved to our new premises in Classon House in Dundrum Business Park, Dublin 14. In February 2010, we became the first firm of Irish chartered accountants to be ISO27001:2005 certified reinforcing the company’s commitment to it's clients data and to technology.


At MBSL we realise that doing what we do has an impact that goes beyond our direct customers. It has an impact on the people who work for and with us, on the planet as a whole and on the communities of which we are part. We are striving to ensure that we have the most positive effect we can, while reducing any negative effects to the absolute minimum. We define corporate social responsibility as doing business ethically and in an environmentally and socially responsible manner, while safeguarding growth and profit in line with our expectations.
