The dematerialization of business processes is one of the main challenges of the current decade. The concept of e-invoicing does not mean only the production and management of electronic invoices: it represents a part of the entire financial value chain and supply chain dematerialization (for its non-commodity component). Indeed the two value chains are now even more integrated and recent studies have shown significant monetary savings. The research question is now to define a reliable set of indicators, which is also able to capture and to synthesize the interactions between the Financial Value Chain and the Supply Chain. In this paper we propose and validate among experts a set of Key Performance Indicators able to monitor these value chains from the financial, strategic, supplier, order and delivery perspectives. The model has been validated through a survey that has been submitted to a number of players operating in different Italian value chains. The results obtained also allow building an assessment model in which a weight is assigned to each indicator and a comprehensive index can be generated.
