Under the proposed ViDA draft Directive, all businesses will need to issue and receive e-invoices for cross-border goods and services. These e-invoices will not be submitted to tax authority (no-pre-clearance) but instead a sub-set of this invoice data will be reported in close to real time (days) by both parties, supplier and customer.
E-Invoices will need to meet the EN-16931 European e-invoicing standard. Work already starting on updating the standard.
