Send payment reminder

Send a Mahnung or Zahlungserinnerung for an overdue invoice, with an optional fee.

MCP tool lexware_office_write → send_payment_reminder

write Confirm

Opens Mahnen on the invoice, uses your saved reminder text, adds a Mahngebühr line when you pass a fee and sends the reminder by email. It works only for invoices created in Lexware Office, not imported ones. The customer receives it at once, and the reminder then appears in the Mahnungen section of the invoice. By default you confirm each call; you can switch that off for this tool.
