Billericay boss Dean Brennan and cub owner Glenn Tamplin were both delighted with their side's FA Cup draw at the Proact.
Ricay and Chesterfield finished 1-1 and will face a first round proper replay at the AGP Arena.
Brennan refuted Martin Allen's pre-game statement that the Spireites were the underdogs.
"They're full-time," he said.
"We weren't the favourites.
"We thought it was a 50:50 game, because of our ability.
"They're the fitter side, more athletic."
He praised his players and felt they had earned the chance to bring Chesterfield back to their place.
"Our players did us proud, our football club did us proud
"I thought a draw was a fair result.
"We saw a lot of belief and character.
"We'll all look at the draw Monday, it's exciting for everybody and hopefully we can do the job at our place.
"It'll be very tough."
Tamplin said Chesterfield were favourites but his team's 'heart' kept them in the draw.
"It was always going to be them, look at the set-up.
"They're a Football League set-up, everything about this club is right.
"We were confident we could come away with a draw.
"You see the amount of goalline blocks, our heart got us through."
Looking ahead to the replay, the owner - who is also assistant manager - is concerned that the smaller pitch at the AGP Arena might favour Chesterfield.
"I believe it's a 50:50 game. They've got as much chance as us.
"On a smaller pitch, I think it will favour them.
"They might have the edge on us, with the physicality of them."
