Practitioners in the e-invoicing industry call on the Spanish Presidency and EU Member States to immediately adopt improved rules for electronic invoicing under Article 233 of the VAT Directive. They argue that removing references to specific control measures for integrity and authenticity would reduce legal certainty and market confidence. An obvious compromise is to require integrity and authenticity be demonstrable within a reasonable time, allow any means to achieve this, and maintain reference to established methods like EDI and e-signatures that Member States accept. Failure to resolve issues further reduces market confidence in the EU's commitment to e-invoicing.
