Ebbsfleet United are struggling to attract enough shareholders to raise their budget for next season.
The Blue Square Premier club, who are owned by fans, had set themselves a target of 12,000 renewal subscriptions by 19 February to meet running costs.
Only 10,000 annual subscriptions to the MyFootballClub website have been secured but club chairman John Moules dismissed talk that Fleet may be sold.
He said: "That is not a route we will be going down at the moment."
Moules, chairman since July, added: "Realistically, we need between 15,000 and 16,000 subscribers to raise the running costs for next season, which are around �500,000 to �600,000.
"19 February was when the first year members' subscriptions became renewable, and we had hoped to have 12,000 by then, but we are still a couple of thousand short.
"People can buy a subscription via the website at any time, and we expect to reach between 15,000 and 16,000 before the new season begins in August."
Ebbsfleet were taken over by supporters' website MyFootballClub in November 2007, with around 20,000 members making a one-off payment of �35 each for a share in the club for a year.
MyFootballClub is a not-for-profit organisation, which was set up in April 2007 with the aim of owning and developing a football club.
The board of Ebbsfleet United at the time approached the website and the Blue Square Premier side was chosen as the team it would buy.
