In Spain, B2B e-Invoicing will be compulsory first for large tax payers (turnover above €8 million) from July 2024. So The Spanish Ministry of Economic Affairs and Digital Transformation and the Ministry of Finance and Public Function published Prior Public Consultation about B2B e-Invoicing on 7/3/2023. The consultation period has different scopes of questions about e-Invoicing such as; interoperability formatting, application of e-Invoicing, platform inter-connection, Invoice status, small company and self-employed adaptations, e-Invoice submission and public administration. Deadline of consultation is 22/03/2023 and there are several questions. It seems that the government wants to be very careful about the implementation phase and wants to take necessary actions about e-Invoicing.
