About us

Complete Rational Solutions Ltd was established by Yvonne Cohen in 2016. It is a member firm of Chartered Accountants Ireland.

Having graduated from University College Cork with a master’s degree in Mathematics and a Higher Diploma in Education, Yvonne qualified as a chartered accountant with Coopers & Lybrand (now PwC) in 1992 and is a Fellow of the Institute of Chartered Accountants. She spent sixteen years in the pharmaceutical industry, working for Warner Lambert and Pfizer.  Initially working as a financial accountant, she later specialised in the implementation and support of accounting systems such as SAP, Oracle, JD Edwards and SunSystems.

After returning to practice, she established Complete Rational Solutions Ltd to provide financial accounting services, specialising in the area of systems implementation. Yvonne has worked with clients on the implementation and use of a wide range of accounting systems suitable for small businesses including QuickBooks, Surf, Sage, Xero and the Big Red Cloud. 

The firm prepares management and annual accounts for clients and assists companies and individuals with income tax, corporation tax and VAT returns.

With over thirty years’ experience as a Chartered Accountant to offer, Yvonne would be delighted to discuss your accounting and taxation requirements.
