In this paper we present implications for using and delivering Enterprise Resource Planning as services (ERP-as-a-service). The objective is to construct a framework of opportunities and challenges for users and suppliers of ERP-as-a-service. The framework is based on a combination of literature study and field study and includes approximately 80 implications. New implications, not found in literature, were identified in the field study. Examples of new implications include: more focus on IT-value; simplified phasing of implementation and improved supplier brand. For future research it is suggested that the framework is tested in a larger setting and that implications are prioritized for certain industries and types of business models.
