We investigate the research prospects for using "Big data" in accounting and finance. The study's goal is to provide a picture of big data academic research in information systems, accounting, and finance, as well as to propose opportunities for future research in accounting and finance. "What are the key topics in existing big data research, and where are the resulting gaps in the accounting and finance literature?" is the study subject addressed in this work. Risk and security, data visualization and predictive analytics, data management, and data quality are the six under-researched aspects of big data in accounting and finance. Increased research in these areas will result in improved industry practices as well as chances for cross-disciplinary study.
