The outsourcing is a greater factor of competitiveness, flexibility, better ability to react to new economic challenges. Although it’s not inevitably synonymic of saving money, it’s a guarantee of budgetary control while relieving the structural costs.
Budgetary control :
  A fixed-term mission
  A challenge, a realization
  No hidden costs

Structural lowering :
  No announcement or recruitment agency costs
  No time spent in hold talking
  No contract of employment
  No computer tool disposal necessary
  No putting at disposition of professional vehicle
  No pay slip
  No management needs
  No social conflicts.

Other indisputable trump card : the flexibility. The company can freely reduce or increase the buckle according to the needs. These adjustments of workforce can be made in some weeks, against several months in the case of a wage-earning team.

Finally, the outsourcing of a commercial resource does not mean for the company a loss of control :
  we subcontract a mission of guarding
  we co-process a commercial mission
