Design and Implementation of General Invoice Print and Management System

Abstract: To solve the interconnection issue of the original invoice management system, this graduated project develops a General Invoice Print and Management System, which includes the billing, invoice management, data submission, query statistics, setting, help, data processing and so on. The billing module realizes the function of single billing, reprinting bill, invaliding bill and refunding bill. Invoice management module realizes the function of payer management, recipient management, information of buying bills and management of bill book. Data submission module realizes the function of importing invoice, reporting data and charging receipt. Query statistics module realizes the function of invoice inventory, invoice query, querying the current information of invoice location about bills reporting, handing in for cancellation and checking the version. Setting module realizes the function of product and project management, invoice location management, drawer management, password settings and print settings. Data processing module realizes the function of data backup, data recovery and data decentralization. Testing results show that the system runs steadily and can satisfy the needs of the taxpayers of different businesses.
