Paul qualified as a chartered accountant back in the 80s. His hobby had always been coding and he was lucky to develop this in to a business in the early 90s with the launch of Thesaurus Payroll Manager. His mix of financial and IT skills together with the help of hugely talented individuals have brought Thesaurus Software to where it is now, a major provider of payroll software for both Ireland and the UK.
