Looking back on the development course of financial management, every change is inseparable from technological innovation. Accounting computerization replaces part of manual accounting work with small database and simple computer software and realizes the leap of computing power and storage ability. The birth of ERP and the popularization of computer network have centralized closed and dispersed finance, and realized financial sharing through process reengineering and professional division of labor. The appearance of RPA robot replaces the manual handling of complex, highly repetitive and large number of tedious affairs, thus reducing the cost of human resources and improving work efficiency. The combination of RPA and AI will further innovate financial technology tools and quietly change the working mode of finance.
