On the occasion of Electronic Invoice Day organized at the beginning of April by the FNFE-MPE, the Directorate-General for Public Finance (DGFip) announced the launch of a pilot phase in the first half of 2024. Made from real data via the Chorus Pro public portal, this pilot aims to test all the features ofe-invoicing (electronic invoicing) ande-reporting (transmission of transaction data) on a small perimeter of about 300 "voluntary" entities: companies, service providers, solution providers (dematerialization operators, software publishers, partner dematerialization platforms). It will make it possible to verify the operation of the device based on the "Y-diagram" and to identify the difficulties, with the objective of reassuring and identifying good practices to be generalized on the following phases.
