Send invoice
Finish a draft invoice and email it to the customer, as a PDF or an e-invoice.
MCP tool sevdesk_write → send_invoice
write Confirm
Finishes the invoice and sends it by email, like Als E-Mail versenden. The invoice number is fixed from this moment and the status changes to open. Format zugferd_pdf sends the PDF with the XML inside (ZUGFeRD); xrechnung_xml sends only the XML (X-Rechnung). Sending is final: if sevdesk is set to enshrine on finishing, the invoice cannot be edited afterwards. By default you confirm each call; you can switch that off for this tool.
