Cloud services change the economics of computing by enabling users to pay only for the capacity that they actually use. In this context, cloud providers have their own accounting models including their billing mechanisms and pricing schemes to achieve this efficient pay-as-you-go model. Thus it is important to study this heterogeneity aiming to map out the existing accounting models to become possible new proposals or future standardizations. Therefore, this paper focuses on mapping accounting models for cloud computing, where a mapping study process was undertaken, and a total of 23 primary studies were considered, which evidenced 5 accounting models, 23 different pricing scheme types and 4 primary studies related to SLA (Service-Level Agreement) composition. Although the significant number of studies found address grid computing it was possible to identify one accounting model which was very complete from different points of view for cloud environments.
