Create payment reminder
Create the next reminder for an overdue invoice and email it to the customer.
MCP tool sevdesk_write → create_payment_reminder
write Confirm
Creates the next reminder for an invoice and sends it by email. The first one is a Zahlungserinnerung; later ones are Mahnungen, which sevdesk offers from the Buchhaltung plan and bases on an invoice that already got a reminder. The text is prefilled by sevdesk unless you pass message, and the deadline comes from your Mahnfrist setting. By default you confirm each call; you can switch that off for this tool.
Parameters
| Name | Type | Description |
|---|---|---|
| invoice_id string required | string | Invoice ID from list_invoices. |
| message string | string | Text of the reminder. Default: the sevdesk standard text. |
