Irish pubs and restaurants are aiming to reopen fully on July 19 ahead of crunch government talks.
Industry bosses are due to meet with officials on Monday to discuss the return of indoor dining.
Antigen testing and vaccine passes will also be on the agenda at the vital discussions.
And Adrian Cummins, CEO of Restaurants Association of Ireland, said that members of the hospitality sector are "working towards" July 19 as the latest reopening date.
He told Morning Ireland on RTE Radio One: "We're working towards July 19, the government hasn't announced that that is off the table, that is the first point we will be raising with the government this afternoon: What date are we working towards, how are we going to get there and what systems are we going to put in place.
"We need to work through all of these logistics, we have issues we want to put forward to the government, and we also have options we want to put forward to the government also.
"The first question is what work has the government done behind the scenes in terms of developing a system, will they use the digital certification system that will be coming into operation from July 19 for aviation. These are some of the questions are going to ask to government, what are they doing and how are they going to implement this.

"Whatever system we put in place, whether it is antigen testing, PCR testing, or a corona pass, we need to look at all of these options, hence we needed NPHET in these talks from the get-go, and unfortunately they are not in there."
It comes as pub and restaurant bosses are appealing for social distancing rules to be scrapped completely if vaccine passes are introduced for indoor dining.
Mr Cummins argued that diners would be "safe" if everybody inside has a confirmed negative test, vaccination, or a recent infection.
He added: "If everybody inside in a premises is safe, whether that is from a vaccination point of view, they've had Covid, or they have a PCR or antigen test, that means everyone inside is safe, that means there must be an economic bonus for hospitality and that means a removal of all social distancing measures so that businesses can get back to normality, to pre-Covid times. That has to be on the table."
