The credit note does not state the invoice it corrects

Symptom

You created a credit note in Billing › Invoice › Customer credit notes, with the New button, and when you click Confirm, fiscaldoo refuses it because it does not say which invoice it corrects. This is the first refusal: only after you state the origin does the note ask for the VAT regularization data.

Message

When you click Confirm on a note without an origin:

“The credit note "Credit note draft" has no origin document, so it cannot be posted. Why: The law requires a credit note to refer to the invoice it corrects (CIVA art. 36.º n.º 6). How to fix: Create it with the "Credit Note" button of the original invoice or fill in "Rectified document". If the origin really does not exist in this system, a Fiscal officer can record the exception with the "Credit note without origin" action, stating the reason.”

If you fill in the Rectified document on a note created by hand:

“Credit note line "[SERV] Generic service" of Credit note draft is not a line of the rectified document "FT D26/31": a credit note can only credit what the document it rectifies invoiced. Remove the line or choose the right document.”

If you enter the number of a document from another program but not the reason:

“The credit/debit note "Credit note draft" does not say why it was issued. Why: The reason for the rectification goes to the tax file (at most 50 characters). How to fix: Fill in "Reason for the rectification" before posting.”

Verified causes

• The note was created with New. That way, nothing links it to an invoice: the Rectified document field stays empty.
• The lines were typed by hand. Even with the Rectified document filled in, a line that did not come from the invoice is refused.
• The VAT regularization data is missing. Once you state the origin, fiscaldoo refuses one thing at a time: first the VAT regularization reason (see The credit note asks for a VAT regularization reason) and, with the cancellation or reduction reason, the Regularization proof and the Regularization reference date.
• The reason for the rectification is missing. This is another field, which goes to the tax file.

What to check

1. Does the invoice you want to correct exist in this system, and is it Posted?
2. If it was issued in another program, do you have its number?
3. What is wrong: the amount or the lines (credit note), or the whole document, issued by mistake (How to cancel an invoice)?

How to fix it

The invoice exists in fiscaldoo

Abandon the draft and create the note from the original invoice, with the Credit Note button: the lines come from the invoice and the link is made. The steps are in How to issue a credit note.

Who does it: Billing or Accountant.

The invoice was issued in another program and you have its number

1. In the draft, fill in Rectified document number (other software), for example FT OLD/2025/123.
2. Fill in Reason for the rectification, for example “Return of goods”.
3. Fill in the VAT regularization data: VAT regularization reason and, with the cancellation or reduction reason, Regularization proof and Regularization reference date. Without them, Confirm refuses, now because of this data.
4. Click Confirm.

fiscaldoo does not check the number, because the invoice is not here: copy it without mistakes. In the demo, the Billing profile posted NC D26/2 this way, without needing the Fiscal officer.

You cannot give the number, or the invoice can no longer be found

The Credit note without origin button only appears for the Fiscal officer profile, on a draft note without an origin. The Billing profile does not see it.

1. Click Credit note without origin.
2. In Case, choose one of the two options:
   • Original document issued by another system: fill in Original document number. Without the number, the window does not close.
   • Origin unavailable (justified): the number field disappears.
3. Fill in Reason and Justification.
4. Click Record exception. The window closes and the button disappears: the draft is not posted yet.
5. Fill in the VAT regularization data, as in the previous case: the exception does not waive it.
6. Click Confirm.

The authorisation is kept in the note's history, for example: “Credit note without origin document authorised by … Reason: Return of goods. Justification: … Original document of another system: FT OLD/2025/123.”

Pending validation by a certified accountant: when the absence of the origin invoice is acceptable for the purposes of VAT Code (CIVA) art. 36.º n.º 6, especially in the “Origin unavailable” case, where the document does not refer to any number.

Who does it: Fiscal officer.

Expected result

The credit note is Posted, with its own number. In the corner, the To settle mark appears, because the credit has not yet been refunded or deducted. The PDF of NC D26/3 reads “Rectifies invoice FT OLD/2025/123: Return of goods” and “Rectified document: FT OLD/2025/123 — Reason: Return of goods”.

For a note of €100.00 with VAT at 23%, checked on NC D26/3:

Account	Debit	Credit
721 Prestações de serviços	€100.00
2433 IVA - Liquidado	€23.00
2111 Clientes gerais		€123.00
