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.
