Description

The invoice root node is the top-level XML element that represents the entire electronic invoice document in the Peppol BIS Billing 3.0 format. It is named <Invoice> and serves as the container for all information related to the invoice, such as supplier and customer details, invoice lines, totals, and tax data. Technically, it is defined by the UBL 2.1 schema (urn:oasis:names:specification:ubl:schema:xsd:Invoice-2) and includes namespaces for common components used throughout the document. All invoice content in a Peppol BIS 3 file must be placed within this <Invoice> element, which marks the beginning and end of the XML structure.
