More than just an accounting department, they make sure that the whole company works well. If Grainbow was a boat, they would be the engineers. From invoicing to accounting, through administrative and legal management, they allow Grainbow to develop peacefully.  They also help the different collaborators in different administrative missions and are in contact with the different service providers of the group. It is very simple, if a collaborator has a question it is towards them that he turns.
