The system comprises of a visual display for invoices, the transactional data regarding these invoices, and the processing of those invoices. The visual display includes a timeline with vertical bars emanating from it, wherein these vertical bars correspond to groupings of invoice data based on user inputted and automated computer inputted information. Users input a start date for the timeline or an amount of elapsed days for the timeline. The timeline includes displaying matched and outstanding invoice data, wherein the visualization allows users to view graphically the interaction between them.
