We switched our business to OSA McQuillan's automatic accounts system and it totally revolutionised how we do our accounts. We do ZERO paperwork outside of work hours now, whereas before we spent hours manually entering invoices onto the laptop. Now the invoice comes in, I take my phone out and take a photo and I forget all about it. I can honestly say I would never be without it again.
Keith Grant, Grants Master Butchers, Roundwood, Co Wicklow
I have worked with Eamon O'Sullivan as my accountant for years and would highly recommend him. He has a no nonsense approach to getting accounts done while still getting the advice across to help raise my income level.
Robert Dill, Director Robert Dill Computing
I cannot recommend Eamon and his team enough, they have a system that not only made my job easier in getting my accounts in order, but they were also incredibly patient and understanding with my current situation and taking the time to demonstrate how to best to get all my papers ready. As someone who is new to doing my own taxes I cannot thank them enough for their help.

Eamon has done work for me for a number of years. His attention to detail has more than once resulted in my receiving tax reabates I didn't know I was due. His service is efficient and punctual.
