Builds an EN 16931 / XRechnung 3.0 invoice in UBL 2.1 or UN/CEFACT CII syntax with seller and buyer electronic addresses, contact, payment means (SEPA credit transfer with IBAN), VAT breakdown per category and rate, and totals rounded per EN 16931 rules (line net = quantity × price, VAT per category = base × rate). Every invoice is checked with the KoSIT validator 1.6.3 and the XRechnung configuration 3.0.2; invoices that are not accepted are not charged and the validator messages are returned.
