$CustomField->setStringValue('dfsdfsfd');
$Invoice->addCustomField($CustomField);


if ($resp = $InvoiceService->add($Context, $realm, $Invoice))
{
    print('Our new Invoice ID is: [' . $resp . ']');
}
else
{
    print($InvoiceService->lastError());
}

Finally i had done it by sending definition id to qb as below

    $CustomField = new QuickBooks_IPP_Object_CustomField();
    $CustomField->setDefinitionId(1);
    $CustomField->setName('POD');
    $CustomField->setType('StringType');
    $CustomField->setStringValue($pod);
    $Invoice->addCustomField($CustomField);
