However, he has stressed he will not allow the Toffees to become a selling club and would allow his top stars to go for big money if it prevented them getting into further difficulties.
Chairman Bill Kenwright admitted the Toffees had reached their credit limit with the banks.
Standing firm: Moyes won't let Everton become a selling club
With expenditure outstripping income by at least ?5million a year he said the tough times were likely to continue until a buyer could be found to inject new investment.
Moyes is well used to working within financial restraints but insists he will not be held to ransom by clubs who think they can take advantage of their predicament.
In demand: Leicester have had a bid for Jermaine Beckford turned down
He said Everton had already rejected a ?2million bid from npower Championship side Leicester for striker Jermaine Beckford, with two other unnamed clubs also having offers turned down.
The Scot has yet to sign any players this summer and knows he has to sell before he can buy, but even if he can offload some fringe players he may not reap the benefit in terms of bringing in new faces.
'Supporters want to see signings in the summer but either we are talking Swahili and people can't understand us but the chairman has been saying we don't have any money,' he said.
'We have not had finances for three or four years. We have always had to trade and I don't think that is any different from before.
'A few years ago we had to trade Andy Johnson and James McFadden and Joleon Lescott to be able to bring players in.
'Managers have to do that - not everyone is going to be gifted with loads of money to spend and you have to do your best without it.
Prize asset: Moyes says he won't let key players like Phil Jagielka leave on the cheap
'Anything we get (from signings) the money will probably go to the bank - it might not be able to be re-invested in players. We are in this situation and we have to get on with it.'
Moyes was unclear as to whether he would get any money from the sale of one major asset - Arsenal have had a bid turned down for defender Phil Jagielka.
But it is not a prospect he is considering after admitting he had not even thought of quitting because of the state of the finances.
'I brought all the players here - everyone by me. I have a responsibility to them," he added.
'There is not a club in the country who does not have a price for every player and if we got an offer big enough I would have to sell.
'But at the moment no-one has come in with an offer which has come close to making me consider it.
Under pressure: Bill Kewright says the bank must be paid before any transfers come into the club
'We had a ?2million bid from Leicester - we have had an offer from three clubs for Jermaine - but we've not had one offer which we consider coming close to what Jermaine is worth.
'I am not going to become a selling club, I am not here to do that I am here to build a strong team and no-one will go unless I say so.
'If I get an offer which is right of course I will [sell].
'I would never put Everton in jeopardy and if we were getting in the situation one or two other clubs have got in then obviously I would have to do something but we are not in that situation.'
Everton's inability to attract outside investors is a puzzling one for Moyes, especially considering Saturday's opponents QPR have just acquired a new owner less than three months after gaining promotion to the Barclays Premier League.
'You'd have to ask a business advisor why,' he said when asked why no-one had come forward to buy the club.
'QPR have got new owners now who are going to give (manager) Neil Warnock a chance to help him in the division.
'He has done a great job in getting QPR up and he needs every opportunity now.'
