Raikkonen was remarkably candid on Thursday when he revealed his main reason for leaving Lotus and rejoining Ferrari was due to the fact he had not been paid.
It is understood Raikkonen was referring to performance-related bonus money rather than his basic wage.
In response, however, Boullier felt the team was more important than one man, regardless of his pivotal role in bringing results.
"The truth is, yes, we owe him money," said Boullier.
"But he is going to be paid, that's true too, and if you want a bit more to the story, last year it was the same in that we owed him some money, but at the end of the day he was paid.
"It's about managing the cash flow, and unfortunately we are not as rich as some other teams on the grid.
"We have obviously favoured our people working in Enstone, which is understandable, I think, and the car development which is the essence of Formula One if you want to compete."
Boullier is confident that despite the picture portrayed of a cash-strapped team, the saga surrounding Raikkonen has not damaged their image or the brand.
