Totalmobile in Belfast has posted a 20% increase in turnover thanks to significant growth in Britain.
The company has secured new clients in England for its mobile solutions, including large councils, health trusts and housing associations.
Its technology is also being rolled out in Surrey by Virgin Care, which provides front-line NHS and social care services across the United Kingdom.
Turnover was up from £8.1m to £9.8m, according to last year's accounts, with its pre-tax profits climbing to over £1.2m – a substantial increase from just under £200,000 in 2012.
The company is recruiting 20 new people, largely software developers, to support the expansion of its business.
TotalMobile's managing director, Colin Reid, said the company was also focused on international growth.
"The health sector in GB has been the main driver of our growth in recent years, but we also are focused on international expansion.
"We have secured our first client in the Netherlands and are also working towards a strategic alliance in the US," he added.
"2014 has been very strong to date, and we expect revenues to increase significantly this year too, something in the region of 30-40%," he adds.
Founded in 1985 and formerly known as Consilium Technologies, TotalMobile's clients include councils, housing associations and private sector businesses.
