QPR chairman Tony Fernandes insists the club have learned from the errors that led to their relegation from the Premier League last season.
The R's booked their place in the Sky Bet Championship playoff final after Monday's 2-1 win over Wigan at Loftus Road - setting up a Wembley showdown with Derby County on May 24.
Whether the west London secure promotion or not, Fernandes has reassured fans that they will not overspend in the transfer window - insisting that the club's finances are secure.
"We're a much wiser group of people than we were two years ago," he said in the Daily Star.
"I'm an accountant by trade and it may not seem like it but we're fine. We've told the fans, whether we go up or we don't, we're here for the long term.
"We know what culture we want at the club. We know what we want in the academy and we will continue the journey whether we're in the Championship or Premier League."
The 50-year-old also revealed that their plans to develop Loftus Road have progressed, whilst insisting that the atmosphere surrounding the club has shifted significantly.
"Off the pitch I think things are going really well. We're making very good progress on the new stadium and hopefully we can announce more soon," he said
"We're kind of almost there on deciding how large it is and what kind of stadium it's going to be.
"On the pitch, it's too early (to say). Let's get the next game out of the way and see how we progress from there. It's going to be a battle," he added.
"Team spirit. A can-do attitude. We didn't have that last season. We have learned."
