The wide application of “Internet+” makes the organic integration of accounting and cloud computing a trend, and cloud accounting is also favored by enterprises for its efficient information sharing and high scalability; however, in the actual promotion due to the openness of the Internet and other special reasons, it also reveals such problems and risks as confusion in choosing cloud services, confusion in service level agreement, confusion in system irregularities and insufficient legal compliance. This paper takes the risk of transmission, storage, and use of financial information in the process of applying cloud accounting in manufacturing enterprises as the research object, to identify, confirm and evaluate the risk factors of cloud accounting and propose counter strategies. The results show that the relationship between the risk factors of cloud accounting are: risk of decision making in applying cloud services > risk of data information security > risk caused by insufficient understanding of service level agreement > risk of system Therefore, the risk of using cloud accounting in manufacturing enterprises is moderate and controllable, and as long as the risk factors are controlled reasonably, the use of cloud accounting is beneficial to the development of manufacturing enterprises.
