In a Workshop on 2023-04-20./21. it was briefly mentioned, that Germany had requested permission to introduce mandatory domestic B2B-e-invoicing already in November 2022 and a “discussion proposal” mentions 2025-01-01 as possible date. The paper proposes XML-invoices in the EN16931-Syntaxes (CII and UBL) as supported by Quba already today.
