This article outlines the allowed workflows in SIGN ES by invoice type; see the diagrams for SIMPLIFIED and COMPLETE invoices below:
Cancellation: it is permitted only in exceptional circumstances; for instance, where the transaction was not carried out and the end customer has not received the invoice in any form (paper or electronic).
Once the invoice data has been sent, we recommend issuing a CORRECTING invoice rather than cancelling.
The invoice is cancelled using the Update an invoice endpoint.
REMEDY: When an invoice fails the tax authority’s validations (status REQUIRES_CORRECTION or REQUIRES_INSPECTION) and no legal correction is required according to the Spanish Invoicing Regulations, you must issue a REMEDY invoice.
An invoice may be remedied multiple times, until it is accepted by the tax authority.
CORRECTING: If an invoice fails the tax authority’s validations (REQUIRES_CORRECTION or REQUIRES_INSPECTION) and a legal correction is required according to the Spanish Invoicing Regulations, you must issue a CORRECTING invoice.
ENRICHMENT: Adding a recipient to an existing SIMPLIFIED invoice.
