A transition towards an economy able to decouple economic growth from resource throughput is needed. An answer to this issue is the circular economy since it pushes the frontiers of sustainability by implementing value ecosystems in which products and materials are used as many times as necessary. Circular business models such as product lease and pay-per-use also called product/service systems (PSS) or product as a service (PaaS) focus on selling service and performance instead of products. The main objective of this paper is to gain more insights into the level of acceptance that the lease/share model of a washing machine can have on developing world citizens from the province of Guayas, Ecuador, a country in South America. In addition, this research aims to study which determinants could affect said acceptance. For the collection of information, this research employed a case study approach. A discrete choice experiment together with different attribute levels and other socio-demographic characteristics were analyzed. Respondents were predominantly focused on the buying market (60%), followed by the pay-per-month model (29.5%), and the pay-per-use model (7.6%). Only 3.5% of the respondents would at this point consider laundry services. The consumer characteristics that were found most important in influencing choice for a payment model were: age, income, and education level of the household head, together with the household size and socio-economic group of the families.
