Cancel invoice

MCP tool lexware_office_write → cancel_invoice

Opens Weitere Aktionen > Stornieren on an open invoice. The original shows a Storno stamp and its booking is reversed, and the cancellation cannot be undone; the cancelled number stays blocked even if you change the number range. A paid invoice needs its payment deleted first, and the restricted role "Belege, Kontakte & Produkte" cannot cancel paid invoices. Use create_invoice for the corrected one. By default you confirm each call; you can switch that off for this tool.
