Invoice type code
Code indicating the document type (invoice, credit note, etc.).
Explanation
Used to distinguish invoices from credit notes and corrections.
Often validated against a code list (e.g., UNTDID/UNCL).
This article treats Invoice type code as a practical reference, not just a navigation page. It explains the term or workflow in context, shows why it matters for European e-invoicing, and connects the topic to invoice creation, validation, routing, archiving, and ERP implementation decisions.
