- Slovenia will mandate B2B e-invoice exchange for all registered entities and self-employed individuals starting 1 January 2028; paper invoices will no longer be allowed in B2B.
- E-invoices must be structured XML documents; PDFs are not valid e-invoices.
- Exchange will occur via secure, decentralised channels (e-routing providers, direct system-to-system, PEPPOL, miniBlagajna); email is not allowed for B2B.
- No changes for consumers: paper invoices remain default unless the consumer opts in to e-invoices.
- The law changes only the invoice format, not tax reporting or fiscalisation rules.
