PIN can split a given telephone invoice, available as file, into single invoices based on the called numbers. This is useful in a multi-person household, where only one telephone connection is available, but each person has to pay its telephone calls on its own.
The data from the telephone invoice are read from a file. Single phone calls are assigned to specific persons, based on the called number. Is a called number already assigned to a specific person, the particular call will be assigned to that person automatically.
The invoices read are stored in a XML-based database. From that data base invoices can be created for each person individually over a fixed period.
Reading and creating invoices is done by plug-ins. PIN can be extended by such plug-ins. Currently invoices from German Telekom (T-COM) given in the CSV format are supported by PIN. Invoices for individual persons are created in HTML format. Created invoices contain an itemized statement as well as the total amount. In the future more plug-ins will be available, supporting digital invoices from different telephone providers.
