E-invoice
ZUGFeRD and XRechnung are built in.
You have had to receive e-invoices since 2025. Issuing them is required from 2027 or 2028 depending on turnover, not at all under the small enterprise scheme (Kleinunternehmerregelung). Honeypod writes both formats and reads incoming ones even without a PDF.
