Family and

Owner-managed and family businesses are the core our client base.   We have a long track record and deep expertise in this area.  In most instances we have worked with our clients for many years, supporting growth, development, succession and change over time.  We are committed to developing a deep understanding of our client’s businesses so that we can provide clear, constructive advice and offer sensible tailored solutions. We appreciate that business strategies must be aligned with the personal strategy of the owners and understand the issues associated with family businesses. At the heart of all businesses are people, generally with ambition, we seek to support these people and their businesses to grow and succeed in sustainable ways that are right for them.

Charity and

Our specialist team have over 30 years of experience providing audit and advisory services to the charity and not-for-profit sector both in Ireland and Internationally. Our clients include:

  • Religious Congregations
  • Schools, Colleges and other Educational Bodies
  • Unincorporated Societies and Entities
  • Home Help and other Community Support Organisations
  • Representative Bodies

We have a detailed knowledge of the sector and the challenges, both regulatory and environmental, that it currently faces. With the establishment of the Charities Regulatory Authority (CRA) in October 2014, and the likely adoption of the Charities Statement of Recommended Practice FRS 102 (SORP), charities and not-for-profit organisations now face increasing level of regulation in Ireland. The new regulatory environment means that organisations must ensure that they adhere to best practice procedures, in both how they operate and report.
Our years of experience has given us a unique capacity to quickly understand how organisations in the charity and not-for-profit sector operate, and a long and proven track record of offering sound advice and developing actionable plans that work for our clients. We take a professional, pragmatic and prudent approach to our work and consistently deliver for our clients.
Our services to the charity and not-for-profit sector include audit & assurance, accounting and bookkeeping support, taxation advisory, payroll services, governance reviews, trustee and key individual support and training, IT and investment consultancy.
