According to Roth and Menor's (2003) framework, a service concept can be defined in terms of the explicit and implicit services surrounding products sold to customers. Explicit services include, for instance, backroom tasks performed during fulfillment encounters between retailers and their customers (Stewart, 2003). Through implicit services, retailers could bring explicit services to the forefront by providing customers information about the backroom tasks performed. This information would allow customers to evaluate services in order to determine whether these services will meet their requirements (Urban et al., 2000).
