MCP tool szamlazz_hu_write → create_invoice
write Confirm
Issues a numbered invoice, which Számlázz.hu then reports to NAV. Returns the invoice number and the net, VAT and gross totals. The buyer gets the invoice by email only if send_email is true; the default is false. An issued invoice cannot be deleted, only cancelled with cancel_invoice. By default you confirm each call; you can switch that off for this tool.
