Verified on 2026-08-17 against European Commission, eInvoicing in Romania. Mandate calendars move, and several of these have moved once already. If you are reading this well after that date, check the source before acting on it, and tell us if it has changed.
How invoices actually move
RO e-Factura, the national platform, operational for issuing and receiving since November 2021 and covering B2G, B2B and B2C.
What the document has to be
EN 16931, through the national RO_CIUS defined by Minister of Finance Order 1366/2021. UBL 2.1 and CII are the usual technical encodings.
What most summaries get wrong
- There is a deadline after the invoice, not just a format. Invoices must reach the platform within five calendar days of issuance, which is an operational constraint rather than a document one and is the part that catches integrations built only around validation.
- Romania publishes a national CIUS, so an invoice that satisfies plain EN 16931 can still be rejected. RO_CIUS is the binding profile.
- Non-established businesses registered for Romanian VAT are in scope too, which surprises foreign suppliers.
Where we fit
InvoiceForge builds and checks the document: it generates an EN 16931 invoice, validates one against the rules a real validator reports, and reads one back into structured data. An agent can call it directly.
It does not transmit. Reaching Romania means going through the network above, and that is a separate piece we would rather name than blur. You need both, and knowing which one you are missing is worth more than a page that implies one product does everything.
