How do I issue invoices in multiple currencies in Romania?

Quick answer (5 steps)

Exchange rate: use the BNR rate from the day the invoice is issued (art. 290 of the Romanian Tax Code).
VAT: it is calculated in RON, at the rate on the date the VAT becomes chargeable — not in the invoice currency.
e-Factura: invoices in foreign currency must be submitted through RO e-Factura (from 01.01.2024), with the amounts in RON.
Archiving: foreign-currency invoices are archived for 10 years, electronically or on paper (art. 110 of the Tax Code).

EUR invoice for IT services exported to Germany — no VAT, exempt with the right of deduction (art. 278 of the Tax Code). You state “VAT exempt under art. 278 CF”.
USD invoice for consultancy exported to the USA — similar treatment: services supplied outside the EU, with no VAT charged.
GBP invoice for a UK customer — post-Brexit, the UK is treated as a third country; the same regime as the USA applies.
EUR invoice with reverse charge — construction services supplied to a VAT payer in Romania; the VAT is calculated and paid by the beneficiary.

Using the exchange rate from the day of payment instead of the day the invoice is issued.
Calculating VAT directly in foreign currency without converting to RON.
Missing the “exempt with the right of deduction” note on service-export invoices.
Failing to submit foreign-currency invoices issued to Romanian B2B customers through e-Factura.
Leaving the BNR rate off the printed invoice (mandatory when the currency is not RON).

The BNR rate is pulled automatically — no need to look it up manually on the BNR website.
VAT is calculated correctly in RON, regardless of the currency you select.
Foreign-currency invoices are submitted to e-Factura automatically, within the legal deadline.
The legal notes (VAT exemption, the article applied) are filled in automatically based on the transaction type.
All invoices are archived electronically for 10 years, with a full audit trail.
