Our support lines are extremely busy as a result of the Temporary Wage Subsidy Scheme being administered through payroll. Our Covid-19 help documentation will generally answer your query.

Also, please note that all of our staff are working from home and may be answering your call in a sometimes chaotic home environment. Please be patient with us.

The operational phase of the wage subsidy scheme, details of which were announced on 15th April, takes effect 4th May. The software has been upgraded to support this.

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.
