Background: The strong growth of e-commerce and the connected last mile delivery problems as well as the increasing customer demands have driven forward delivery innovations in the past years. One of them, parcel locker networks, were developed and have been growing for several years. However, customers still seem to prefer the traditional home delivery, which is highly inefficient for last mile delivery actors. Thereby, it has to be evaluated whether customers are satisfied with the parcel locker technology and which factors determine the satisfaction. 

Purpose: This study aims at evaluating the factors influencing customer satisfaction in regard to parcel lockers. Therefore, relevant constructs about satisfaction and acceptance models in the last mile context were derived from the literature.

Method: In order to accomplish our purpose, a quantitative study was conducted using a questionnaire among end customers in Austria and Germany. The proposed framework and hypotheses were analysed by using structural equation modelling. Furthermore, a multigroup analysis was conducted to identify differences between sociodemographic categories. 

Conclusion: The results show that perceived ease of use, perceived quality and convenience perception all have an influence on customer satisfaction in Germany and Austria. However, the direct influence of perceived ease of use and convenience perception cannot be confirmed, both constructs are entirely mediated by perceived quality. Furthermore, the multigroup analysis determined significant differences in the gender category for the path between perceived ease of use and convenience perception, in the living area category for the relationship between convenience perception and perceived quality and in the age category for perceived quality and customer satisfaction.
