Updated version of the "External Specifications File for Electronic Invoicing."

Specifically, it includes the introduction of mandatory data that must be included in all e-invoices, revised and new use cases, changes to the required frequency for reporting e-invoicing data, updated guidelines for retaining invoices via the public billing portal, and detailed explanations and examples for creating XML files for e-invoicing. Overall, these changes are aimed at making the e-invoicing process more streamlined, efficient, and compliant with the latest regulations. The specifications will be updated during the year before the e-invoicing mandate goes into effect. The specifications are available on our Fiscal Portal.
