ABSTRACT
The term 'eco-services' has different definitions with regard to the understanding of the word 'services' as well as the prefix 'eco'. It is therefore necessary to differentiate and state more precisely the topic of the research. Services can be divided into primary services and secondary services. Primary services are pure services—those that do not offer a material component (the product) with the service. Secondary services do contain a product component and are product–service combinations. In the case of result-oriented services, the product itself is not marketed but rather the result of the product is marketed. Leasing is the mid- to long-term rental of mobile or immobile goods in exchange for payment in instalments over a prearranged or unlimited period of time. Hire purchase also falls under the heading of sale of user units. It is similar to leasing in terms of purchase in instalments and framework conditions.
