An invoice transmitted to the RO e-Factura system cannot be deleted or modified: once validated by ANAF, it stays permanently on record. The correction is done exclusively through a credit note (storno) — a new document, with negative values, that clearly references the initial invoice — followed, if the transaction remains valid, by issuing the correct invoice.
The rule comes directly from ANAF: an electronic invoice is corrected only through a credit note, without modifying the initial invoice. The storno invoice is transmitted through SPV as well, within the same 5-working-day deadline from issuance.
Why you cannot simply delete the invoice
When uploaded to SPV, the invoice receives an upload index, and after validation an ANAF receipt — the document becomes part of the national fiscal record and can no longer be withdrawn. Any correction must leave a trail: it is done through a new document, not by editing the existing one.
This protects both parties: the buyer sees in SPV both the initial invoice and its reversal, and during a fiscal inspection the whole correction chain is traceable.
Full storno or partial storno?
A full storno cancels the initial invoice entirely — use it when the invoice was issued to the wrong client, the transaction never happened or the document is a duplicate. All lines are re-issued with negative values.
A partial storno corrects only the wrong lines — an incorrect quantity, a wrong price on one product, an omitted discount. The rest of the invoice stays valid, and the storno covers only the difference.
The reference to the initial invoice is mandatory
The storno invoice must explicitly reference the invoice it corrects (the number and date of the initial invoice). Without this link, the buyer cannot associate the documents, and accounting systems frequently reject or block "orphan" credit notes.
If you also issue a new, correct invoice, make it easy to associate as well — mention the correction context in it.
The practical steps
- Identify exactly what is wrong: the whole invoice (full storno) or only certain lines (partial storno).
- Issue the credit note with negative values and the reference to the number and date of the initial invoice.
- Transmit the storno through SPV within the 5-working-day deadline from issuance.
- If the transaction remains valid, then issue the correct invoice and transmit it too.
- Keep all the documents — the initial invoice, the storno and the correct invoice together form the correction file.
How BIWizz helps you with credit notes
In BIWizz, the storno is a guided flow: you pick the issued invoice, and Wizzy prepares the credit note — full or partial — with the negative values and the correct reference to the initial invoice. Transmission to e-Factura happens only after your confirmation.
The same flow works through the MCP connector: you can request a storno directly from Claude or ChatGPT, with the same preview and human confirmation before any transmission.
