Outsourcing giant Mount Charles has said it gained new business totalling £5m over the past year.
The Belfast-based group -which works in areas from security to cleaning, catering and vending machines - said revenue had grown by 21% in the past 12 months, and by 40% in the last two years.
It recently won a contract worth €500,000 (£367,400) to run catering and vending services at a major employer in the north west of Ireland.
Managing director Cathal Geoghegan said the group's expansion and diversification had helped it grow rapidly in the last five years.
"The cleaning division for example now generates annual revenue of around £4m. It was formed in 2010 and is gaining fast on our contract catering division, which of course was once the only thing we were known for. The business has evolved significantly, and we've been looking at new markets as well as new services.
"The Republic of Ireland in particular is becoming an increasingly important market for us thanks to the rapidly growing demand for bundled, outsourced business solutions."
The group recently formed a joint venture with RMS Group, specialising in cash in transit and security.
Mr Geoghegan said: "Our partnership with the RMS Group has already allowed us a significant number of business gains.
"It was a strategic move that demonstrates our ability to provide a wide spectrum of outsourced business solutions.
"Offering these cost effective, bundled services is what it takes to thrive in the very competitive industry in which we operate."
