Abstract:With the increasingly fierce market competition, the importance of cost control for the enterprise is increasing. Financial reimbursement system is an important window of enterprise cost expenditure, which plays a key role in controlling the cost of enterprises. Traditional financial management software focuses on the business process. The management and control of reimbursement is weak, and all levels of managers in the examination of the expense claims have to approve in vain due to the lack of relevant information. In this paper, the intelligent sanction system of expense claims provides decision support for the approval of the expense claims, improving the efficiency and quality of the sanction and reducing the cost. The basic function and application process of the intelligent sanction system of expense claims are introduced in detail.
