Defining scope

Could you please give an advice about how to tackle this problem??

Answer: For such small number of employees, the most efficient way is to include all organization in the scope, because the effort to manage the interfaces and interdependencies with the areas outside the scope will be greater than consider all the areas of the organization. Customers and logistic partners are considered as interested parties that should be considered in the definition of the scope, not included in the scope itself.
