Hi again,

am I missing something here? what do you think?

"Coûts cachés, options inutiles, devis non pertinents constituent de véritables axes d’optimisation"??

this comes under heating "réduire les coûts sans perte de qualité ni de service

I think that there's a missing word here, I'm thinking "..constituent de vrais freins au axes..

Thank you in advance
