fatal CII UBL auto-fix
A rule for exports outside the EU (category G): the rate is 0, a seller VAT or tax registration identifier is present, and the VAT breakdown states the exemption reason. This is an error: the invoice is rejected until it is fixed.
Automatic fix: 9 € per file (excl. VAT where applicable). The export VAT breakdown taxable amount is rebuilt from the lines (existing breakdown required). The result page shows which errors the repair removes and whether the corrected file then passes — before you pay. Many files? Pilot and Repair API.
[BR-G-08]-In a VAT breakdown (BG-23) where the VAT category code (BT-118) is "Export outside the EU" the VAT category taxable amount (BT-116) shall equal the sum of Invoice line net amounts (BT-131) minus the sum of Document level allowance amounts (BT-92) plus the sum of Document level charge amounts (BT-99) where the VAT category codes (BT-151, BT-95, BT-102) are "Export outside the EU".
The export VAT breakdown taxable amount is rebuilt from the lines (existing breakdown required).
This rule is in the deterministic set of our repair engine (UBL 2.1; measured 2026-10-23: XRechnung 15 broken test invoices accepted after repair, 45 valid invoices unchanged; Peppol BIS Billing 3: 10 official examples unchanged, 40 mutated invoices: 36 accepted after repair, 4 rejected as expected — one documented limit, two with the repair parameter switched off, one where no address could be derived; profile conversion of 33 XRechnung test invoices to Peppol: 30 accepted). For UN/CEFACT CII (Factur-X / ZUGFeRD EN 16931 XML, XRechnung CII) the engine repairs the totals chain, VAT breakdown, rounding, decimals and element order (measured 2026-10-24: 53 valid CEN and XRechnung CII invoices unchanged; 28 broken invoices: 27 accepted after repair, 1 rejected as expected because a VAT exemption reason cannot be derived). Single files: 9 € on the result page; many files: the Repair API — see Pricing.
