Activity in the country's services sector rose last month at the fastest rate since May 2022, according to the latest Purchasing Managers' Index from AIB.
The report shows that business growth also accelerated in November at the fastest rate since April 2022, with the strongest increase in employment recorded since March.
AIB said the upturn was broad-based by sector with a renewed expansion in Transport, Tourism Leisure.
The seasonally adjusted AIB Ireland Services Business Activity Index rose for the third month running to 58.5 in November, from 56.7 in October - the steepest rise in output since May 2022.
A reading above 50 indicating an overall increase compared to the previous month.
Financial Services (60.9) recorded the sharpest increase in activity, closely followed by Technology, Media & Telecoms (60.3).
Business Services (57.7) was the only segment to see slower growth than in October, but still a marked increase, while Transport, Tourism & Leisure (53.3) registered the first expansion in activity since February.
New business growth accelerated for the fourth successive month and was the strongest since April 2022, led by Financial Services.
The Services PMI also shows that new export orders rose at a solid pace that was broadly in line with those posted in September and October.
"Stronger demand for services and higher levels of work outstanding drove service providers to raise their staffing levels to a greater degree than in the previous survey period," according to AIB.
The rate of job creation was the fastest since March and it moved back above the long-run survey average.
"Employment rose due to higher customer demand and proactive recruitment for anticipated company expansions."
Financial Services posted the strongest jobs growth, while Technology, Media & Telecoms recorded a third reduction in staffing in the past four months.
Cost pressures remained relatively strong in November, although the rate of input price inflation eased to a three-month low.
"Higher wages, increased service and energy costs, insurance rates and pension costs drove input price rises for businesses."
AIB said service providers raised their charges at a stronger rate, with costs continuing to rise sharply and demand strengthening. It said charge inflation was the highest since January.
AIB Chief Economist David McNamara said the AIB Irish Services PMI for November shows a sharp acceleration in growth in the sector.
"Overall, the rate of growth in the Irish services sector continues to outperform the euro zone, UK and US flash PMIs at 53.1, 50.5 and 55, respectively."
Mr McNamara said firms in the Irish services sector were "more optimistic on the prospects for expansion in activity levels over the coming 12 months."
"Confidence recovered from October's four-month low, reaching the highest level since February," he added.
