What this means for you

This is not a general Hungarian B2B mandate. Since July 1, 2025, the e-invoice obligation is limited to specified electricity and natural-gas suppliers invoicing non-private customers; Hungary also operates separate real-time invoice-data reporting.

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.
