B2C e-invoicing since January 2025
Model Central clearance via ANAF's SPV platform
Format RO_CIUS (EN 16931; UBL 2.1 or CII)

Romania introduced mandatory B2B e-invoicing on 1 January 2024 (Law 296/2023) and, like Italy, operates a clearance model through the state platform RO e-Factura.

Clearance via RO e-Factura / SPV

Invoices pass through the SPV (Spatiul Privat Virtual) of the tax administration ANAF, which runs structural, syntax and semantic validation and applies a Ministry of Finance signature to the validated invoice. Submission must happen within a few calendar days of issuance. Since January 2025 a B2C mandate also applies.

The RO_CIUS format

Invoices must conform to RO_CIUS — the national, EN-16931-compliant usage specification, in either the UBL 2.1 or the CII syntax. That ties Romania fully to the European data model; alignment with the ViDA rules follows by 2035.

How invowerk helps

invowerk validates RO_CIUS-adjacent UBL or CII invoices against EN 16931 and explains every BR error code in plain language (see /codes). Submission must go through RO e-Factura; the upstream format and field checks plus UBL/CII conversion are handled by the API.
