Sage has been rated the UK's top software company in a report by Pricewaterhouse Coopers (PwC).
"Sage has maintained its leading position in the sector in terms of revenues and remains focused on maintaining this position through its Software-as-a-Service (SaaS) offering," said the report.
Misys ranked in second place, followed by Autonomy, Logica and Acision.
Jass Sarai, UK technology leader at PwC, said UK companies continued to evolve, innovate and adapt to market conditions. He added that the popularity of mobile devices, the consumerisation of IT and the adoption of cloud computing have forced software companies to rethink business models.
But the UK market will fail to compete with the US, claimed Jass Sarai.
"The sector remains dwarfed by global giants in the US, a country that has a long history of supporting the industry financially and cultivating a real entrepreneurial culture. Many countries have sought to re-create the Silicon Valley phenomenon, but have failed," he added.
PwC rankings are based on products (licence and maintenance) and subscriptions revenues earned by the local companies.
The UK contributed six companies to PwC's global top 100 software companies.
