The Dunedin founded social business uses an IRD subsidy to provide small businesses and charities throughout New Zealand with a free payroll service.
A new chief executive, Christina Bellis, has been appointed while an office has also opened in Wellington. Three staff work from each office.
Incumbent chief executive Lani Evans, who joined the company in 2013, has stepped down from the position but continues as a director of the company.
Thankyou Payroll was founded five years ago by Hugh Davidson, who identified a gap in the market for such a role. It includes a charitable trust which distributes funds to community organisations.
Ms Evans, who was a finalist in the future leaders category of the Otago Chamber of Commerce OBiz awards last year, felt it was a good stage for her to move more into a governance role. She was very proud of what the team had achieved.
When she joined Thankyou Payroll, there were fewer than 200 clients and two staff members and her aim was to drive the growth and development stage of the company.
Now it had almost 2500 clients, a good profile and a very solid reputation and it was an opportunity for someone with new energy and ideas to come into the business and add benefit, she said.
Canadian born Ms Bellis, who is likely to start her new job at the end of September, initially came to New Zealand on a working holiday visa eight and a half years ago.
She had a diverse background, which included co ordinating the Great Canadian Shoreline Cleanup, a ''massive'' project, involving 60,000 volunteers across the country.
It was one of Canada's largest environment events and all rubbish was identified, counted and then analysed.
Her first job in New Zealand was working with councils throughout the country on climate change mitigation, as part of Communities for Climate Protection NZ.
When the Government changed and the programme closed, she thought about returning to Canada but the global financial crisis was ''in its absolute lurches''.
Her Toronto based parents told her she had two options - either return to Vancouver, where she previously lived, but she would need about 18 months worth of living expenses, or move back to Toronto and live with them and ''ride it out''.
Much as she loved her parents - ''they are the hardest part of living on this side of the world'' - neither option was ideal, and they also suggested she should stay in New Zealand, if she could get a job.
She was asked to assist the Wellington based Sustainability Trust, initially on a 30 day contract, helping book people in for assessments for home insulation.
The trust was a social enterprise working with households, communities and businesses to provide practical solutions in energy efficiency, waste minimisation, water conservation, transport and food management.
Social enterprises and not for profit organisations, in general, were ''doing things on the smell of an oily rag''.
The trust, at that stage, was under resourced, yet trying to do major changes, and she could see everyone was working at more than their capacity.
She took over managing community projects and the trust consolidated for a year, as it had been ''trying to be everything to everybody'', and then started to grow its programmes.
A lot of work had been done with schools in helping them change waste systems and that had moved into the business community over the past couple of years, and the trust was now helping with energy systems, as well.
It was helping make changes to save money and lower environmental footprints. It was trying to empower people to make changes that were good and ''pay it forward'' to others.
It was about having a great idea and inexhaustible energy to make it happen and she saw that in both the Sustainability Trust and Thankyou Payroll.
She managed the fit out of the trust's new EcoCentre and the trust won a Ministry for the Environment Green Ribbon Award for small business leadership as a result.
The trust had grown throughout the recession and helping to be part of that growth would also hopefully help her guide Thankyou Payroll through its growth, which was exciting, she said.
Describing herself as a ''do-er'' kind of person, Ms Bellis said Wellington had been a great place for meeting people and networking.
She intended working from the company's Wellington office and was also looking forward to spending time in Dunedin.
While it would be sad to leave the trust, it was exciting for others to ''bring it on and breathe some new love'' into it, and maybe take it in a new direction, she said.
Ms Bellis was also a trustee and long time co ordinator of Frocks on Bikes Aotearoa, a voluntary organisation to encourage people to use a bicycle as part of everyday transportation.
She set up Environment Hubs Aotearoa, a national collective of environment centres and like minded organisations, and is chairwoman of the board.
A keen gardener, she founded the Local Food Network to encourage support of businesses, farms and co operatives in the Wellington region.
