Upon each payment, a fiscal receipt is issued. The payments are for different types of invoices and documents. In order to accomplish that, the Cashier is integrated with different Web Services.
• InvoiceImage Invoice Image is a multifunctional document generation system. It produces different types of invoice documents, based on user requests. Invoices can be in PDF, Excel or CSV formats. In addition to the online files, the system produces specialized versions for paper printing and CD burning as well.The system is divided into two separated applications. The first one is the invoices generation engine (invoice producer) which provides the required file. The invoice producer is responsible for generating PDF, XLS and CSV file formats for invoices. The application is stateless and many processes of generation can be started and serve requests without the need of a clustered environment. Started instances are grouped with a High availability proxy server that handles the requests in a round-robin fashion. Several groups can be started and configured to handle different request channels, i.e. CRM channel, batch processing channel (paper print jobs), web page and etc. This architecture allows each group to have one entry point for the requests, the HA proxy, and as many workers as it is needed to satisfy the request channels load.

The system allows the management of a portfolio of loans disbursements and repayments, calculation of due regular and penalty interest on a real-time calendar, management of collateral and insurance, quick and easy access to a wide range of reports and reporting, and maintenance on a customer database.
