Send invoice reminder
Emails a reminder for an overdue invoice, with the original invoice attached.
MCP tool teamleader_write → send_invoice_reminder
write Confirm
Works only on an invoice past its payment term, like the Reminder button in the app. The mail uses the invoice email template you name, or your text, and adds one to the reminder count. A Peppol invoice is reminded by email. Returns the address used and the new count. By default you confirm each call; you can switch that off for this tool.
