When we ask for an advice, we pay for it. When we go to see a doctor, we pay for the consultation and not when we are in good health. It is the same for professionals of consulting: layers, accountants, etc.
Cooperation Concept used to offer services that it was possible to pay after having results. Unfortunately, we have faced too many unpaid missions, which put the structure in danger. These experiences also showed that most of the time the trained association was keeping information for itself, reducing the chance of having results, and finally associations were giving us missions that were not adapted to our competences.
