Economy minister Ken Skates said Welsh Government is "working urgently" to back non-VAT registered firms in Wales - but says he can't promise immediate help.
While billions of pounds is being delivered to businesses from UK and Welsh governments there remains groups that have slipped through the net.
These include micro firms who are not registered to pay VAT - with concerns over protecting any system from fraud holding up support for this vital part of the Welsh economy.
Mr Skates said a "discretionary bursary fund" was one system now being looked at.
Business Live has been pressing on this issue along with Daily Post columnist Dylan Jones-Evans - highlighting business owners like Michelle Mellor-Edwards who runs Micky’s Professional Catering Business at Prestatyn Golf Club.
Her firm, like thousands of others, could not apply to the Economic Resilience Fund as they hadn't passed the £85K threshold to pay VAT.
The issue of non-VAT companies was raised today by Business Live with Economy minister Ken Skates.
He said: "Those businesses that are not VAT registered have been a key concern of ours - trying to develop a support package as part of the second wave of the Economic Resilience Fund.
"We have been hoping the UK Government would bring forward support for this group of businesses.
"The difficultly for all of those great minds in the UK Treasury and for us in Welsh Government is in the development of a scheme that is able to withstand widespread fraudulent attempts to extract cash, taxpayers money.
"So that's why one of the conditions of the Economic Resilience Fund first wave was the requirement to have VAT so we could check that against the registered address to ensure the business does indeed exisit.
"We are considering a bespoke support system for businesses that are not VAT registered, some of our thinking right now includes the potential of a discretionary bursary fund that could be administered on a regional or local basis.
"We believe that this particular intervention may be the most viable of all of those that we are looking at.
"I can't promise that we will have this system rolled out within the next few days but we are working urgently to put the processes in place to be able to support non-VAT registered businesses at the very earliest opportunity."
