All 40 remaining paid staff of the club were made redundant on Monday and Gretna appeared to be heading towards closure.
However they could have a future in the First Division of the Scottish Football League if the bid, thought to have come from the consortium headed by Glasgow businessman Paul Davies, is considered a viable proposal.
Gretna have finished bottom of the Clydesdale Bank Scottish Premier League and will be relegated if they avoid liquidation.
Administrator David Elliot of Wilson Field Ltd told Setanta Sports News: "I received an offer through a solicitor acting as a purchaser.
"We're in a situation where we're still a member of the SPL but we don't have any staff. There's an automatic right for Gretna to enter into the SFL but at what level is open to debate.
"I haven't got a specific deadline. Yes I can give some hope - what we're waiting for is the purchasers to supply me with a three-year business plan.
"I'll review that, if I think it's workable I'll contact the SFL. That's the plan at the moment and that's what we're working on."
