When a corrective is needed

Once an invoice is validated, it can’t be modified — the numbering is irreversible. To correct errors, a corrective invoice is issued, referencing the original and voiding it fully or partially. Typical cases:
  • The amount was wrong and needs adjusting (up or down).
  • There was a date change after validation.
  • The billable customer changes (the invoice goes to a different person or company).
  • Lines need to be added or removed.
  • The reservation was cancelled and the amount needs refunding.

How it’s done

Correctives are handled on our side. Contact support with:
  • Booking reference
  • Number of the invoice to correct
  • What needs fixing (amounts, customer data, lines, etc.)
  • If the corrective implies a refund, how to process it (original method, credit, etc.)
We let you know once the corrective is issued.
The corrective is always sent to the tax authority (AEAT in Spain) via VeriFactu, just like the original. Fiscal traceability is preserved end to end.

Common cases

Don’t worry — contact support and we’ll correct it with the right data. The original invoice is voided by the automatic credit note.
The corrective with 0 € amount (full credit note) is issued from our side. Let us know whether the refund goes back to the original method or stays as credit for future stays.
If the invoice is not under VeriFactu and less than 48h have passed, you can update the contact data from its record and the new data shows on the invoice — the full step-by-step is in Modify invoice details. In any other case (typical in Spain), contact support: changing the invoiced customer data requires a corrective.
If after the corrective there’s an overpayment, when you contact support let us know whether to refund it to the original method or leave it as credit.

When to contact support

Whenever you need a corrective. Accounting changes to a validated invoice are handled from the Odoo back-office.
Don’t try to “void” the validated invoice by deleting it directly. Fiscal numbering and submissions to the tax authority can’t be undone — always use the corrective.
