Financial management is an integral part of enterprise management. It is an economic management work that organizes enterprise financial activities and handles financial relations based on financial laws and regulations and the principles of financial management. Simply put, financial management is an economic management work that organizes enterprise financial activities and handles financial relations.

[0003] In the prior art, bills are often needed in the process of financial management. In order to bind and preserve the bills, a punching device is needed. Before binding, holes are punched on one side of the bill by the punching device to facilitate the subsequent sorting and storage of the bills.
