85 per cent of Irish businesses have scaled back or closed completely as a result of the coronavirus pandemic.
Chambers Ireland carried out a survey of more than 1,300 members across the country this week.
It found that only 15 per cent of businesses remain fully open.
Of the 85% closed to some degree, 27% have scaled back activity, 24% have font of house closed with staff working from home, and 34% have shut completely.
Most businesses say they will need at least two weeks' notice to re-open, while one-quarter of businesses say it will take at least a month.
A small number of businesses - in agri-food, tourism and hospitality - say they will have to wait until next year to reopen.
