Triple Entry Accounting (TEA) provides an opportunity for fundamental change in accounting. TEA is a foundational development of Blockchain technology, which is considered a pillar of the Fourth Industrial Revolution. Nevertheless, in order to augment its impact, TEA should be integrated with other systems. This paper aims to examine the relationship of TEA with system integration (SI) and how it can affect integration. This study reviews the SI literature in the context of accounting, examines how the literature on TEA has evolved over the years, and finally contributes to the analysis of how TEA is related to integration. A key theme is the connection of accounting controls and system integration. The methodology of the four design principles of control in system integration is adopted. Transparency is the main perspective of these principles. It was found that TEA promotes transparency, reduces the risk of fraud, and facilitates system integration.
