Cork's National Business Machines Group (NBM Group) is set to invest €1.8 million in its infrastructure in Dublin over the next 12 months.
Founded in October 1985 by Michael Galvin, NBM Group provides managed print, IT, audio-visual, and graphic comms solutions to clients across Ireland.
It said this latest investment will support growth across new business areas.
The move will see the company establish new premises and create five new jobs next year.
"As we celebrate 40 years in business, NBM is entering one of the most exciting periods in our history," said Mark McPhillips, CEO of NBM Group.
"The investment and expansion we're announcing will not only strengthen our presence in Dublin but also accelerate our growth across Ireland.
"With new services in managed IT, and AV, our goal is to double the size of the business within the next five years," he added.
