Send or finish a sales invoice

Emails a concept invoice to the customer or saves it without sending.

MCP tool snelstart_write → issue_sales_invoice

write Confirm

Does what Versturen or Alleen Opslaan does in step 4. SnelStart assigns the invoice number at that moment, so the invoice stops being a concept. Sending needs the customer email address on the card and attaches a UBL file. By default you confirm each call; you can switch that off for this tool.
