What this means for you
Slovenian B2G e-invoicing has applied since January 1, 2015. ZIERDED requires Slovenian business entities to exchange structured e-invoices for mutual domestic supplies from January 1, 2028; ordinary email is not an allowed B2B exchange route.
What FreeBillGen can verify
For eligible saved invoices, FreeBillGen can prepare generic OASIS UBL and UN/CEFACT CII mappings and run its named internal checks. These mappings are not EN 16931, Factur-X, Peppol, national-CIUS or clearance-platform validation. FreeBillGen does not transmit them through a provider network.
Check this route in Invoice PassportThe free Inbox can manually parse selected UBL/CII supplier files for review. Syntax recognition is not profile validation; manual upload is not a Peppol or government-network receiving endpoint and does not by itself satisfy a receive obligation. Open manual upload
