import sales order via web services

Hi I am trying to import sales orders through web services without billing the customer. When I run the following code it is billing my customers again that have a default CC assigned.

// create array of fields
$purchaseOrderFields = array (
'entity'  => array ('internalId' => $netsuiteId),
'account' => array ('internalId' => 131),

'ccApproved' => 'T',
'customForm' => array ('internalId'=> 95),
'tranDate' => $date,
'itemList'  => array (
   'item' => array (
     array( 'item' => array('internalId' => $leadtypeId),
       'quantity' => 1,
       'rate' =>$rate,
       'taxCode' =>$taxcode))

   
)
);

// create purchase order record
$purchaseOrder = new nsComplexObject('CashSale');

// set fields
$purchaseOrder->setFields($purchaseOrderFields);

// this will create a purchase order with 1 line item
