This research addresses the decision to either manage the Enterprise resource planning (ERP) information technology infrastructure or contract cloud computer services through the software vendor.  ERP integrates business functions into a single information technology system to support enterprise-wide operations and decisions. Although challenging to implement and manage, these systems provide essential benefits of a single database platform and uniform usability.  The vast majority of organizations use an ERP application that has been developed by a relatively small set of vendors and are on-premise (on-prem) installations. Cloud computing refers to vendors hosting resources and applications for organizations to access through the Internet.  Customers then purchase the rights to use the Cloud-ERP functionality via subscriptions.  Cloud computing can replace a private datacenter by utilizing licensed facilities to provide organizations with high levels of computing power. Accessing software through the cloud is referred to as software-as-a-services (SaaS). Although implementation and management of ERP application is a very active area of research, there is a gap in the literature in the decision process of an ERP implementation through cloud computing. This research reports on the conversion of the major ERP vendors to SaaS. The advantages and disadvantages of each implementation choice is describe to support decision making for ERP adoption and conversion efforts.
