Monetary fund is the asset with the strongest liquidity and the most difficult safety control in enterprises, an important part of enterprise assets and an indispensable cornerstone of production and business activities. Standardizing the safety management of monetary funds and strengthening financial supervision can better prevent financial risks and organize financial activities of enterprises more reasonably, thus improving the utilization rate of funds and economic benefits of enterprises. According to the relevant national financial laws and regulations, combined with the actual situation of our company, this paper probes into how to strengthen the safety management of monetary funds. The first is to establish a monetary fund budget management mechanism. The monetary fund management of enterprises must implement comprehensive budget management. Budget can make the production and operation activities of enterprises proceed in an orderly way, and ensure that the income and expenditure of funds in the production and operation activities of enterprises are included in strict budget management procedures. According to the overall goal of the capital budget, raise and use funds in a unified way, adjust the surplus and deficiency of funds, determine the economic and reasonable cash balance, and decompose and issue the capital budget. The annual revenue and expenditure shall be strictly controlled within the annual financial budget. Over-budget projects shall go through the relevant examination and approval procedures, and the financial department shall not pay for the additional projects and expenses that have not fulfilled the examination and approval procedures. Two, establish and improve the internal control system of monetary funds. 1, separation of functions control: enterprises should establish a strict organizational division of labor and post responsibility system for monetary fund business, that is, consider the separation of incompatible posts, and two or more departments or staff members should undertake some incompatible posts respectively to avoid or reduce the occurrence and control of errors and drawbacks. 2. Establish and improve the fund examination and approval management system: standardize the examination and approval procedures: In order to ensure the safety of funds, the enterprise's financial revenue and expenditure must conscientiously implement the enterprise's internal control and the fund use examination and approval system, strictly follow the prescribed examination and approval authority and procedures, reduce some unnecessary expenses, and reveal the weak links of internal control in other businesses related to the fund business. The receipt and payment of monetary funds must be filled in or obtained with reasonable and legal original vouchers, which can be used as the basis for compiling accounting vouchers and registering account books after examination and approval. No payment will be made for illegal original documents, invalid contracts or agreements and incomplete examination and approval procedures. Iii. Other key points for strengthening the safety management of monetary funds: 1. Strictly control the expenditure of monetary funds and control the inflow point of monetary funds: as the risk management department of the company, the finance department must formulate relevant approval authority and procedures as the basis for monetary funds expenditure. And all fund business expenses are strictly prohibited from being handled in any other department except the financial department. The fund business income shall be recorded in a timely manner without delay, and no department or individual may intercept, occupy, transfer or conceal funds for any reason. 2. The reserve fund shall be subject to quota management: in principle, the cash stored in the safe overnight shall not exceed the reserve fund limit set by the company. The cashier should check the cash on hand every day to ensure that the accounts are consistent. The chief financial officer shall conduct random checks on the cash balance on hand from time to time, and find out the reasons in time and deal with them accordingly when finding the shortage of funds. And strict cash expenditure scope, strictly in accordance with the provisions of the China Municipal People's Bank of cash expenditure within the scope of the use of cash. 3. Strengthen the security of online banking and the management of system software: when using online banking to handle business payment, it is necessary to set up more than two positions of handling personnel and reviewing personnel, grant different business rights and set their own operating passwords. Every computer should install a virus firewall, regularly kill viruses, and regularly use a large-capacity mobile hard disk to copy data for archiving. 4. While improving the safety management measures of monetary funds, we must pay attention to the professional knowledge training, post responsibility education and professional ethics education of financial personnel. Constantly improving the overall comprehensive quality of financial personnel is also a strong fortress to ensure the safety and effectiveness of funds.
