Country Situation
Andorra has introduced a phased B2G e-invoicing regime as part of its public procurement reform. The public-sector e-Invoice portal and register was launched for the general administration on 1 October 2024, with paper invoices accepted only until 1 January 2025. From 1 January 2026, the same model extends to communes and other public-sector entities.
The legal obligation is on public authorities, who must receive invoices via the portal in structured electronic format. Suppliers are not directly mandated to issue e-invoices under the regulation, but in practice, any invoice submitted to public bodies must go through the portal (or an alternative channel authorised by regulation), making e-invoicing a de facto requirement for suppliers.
The regulation highlights interoperability with EU/EEA standards (EN 16931), and Peppol BIS Billing 3.0 (UBL 2.1) is supported for B2G delivery.
