In order to automate a sales order into a cash sale record there are certain fields that must be populated. On any sales order record, under the Billing subtab you will see the field Payment Method or Payment Option. This is the trigger point in the system to let NetSuite know that you are receiving a form of payment on this order rather than sending this to an Invoice record. By populating a value into this field NetSuite will convert this into a cash sale. If this field is empty, then by default the record will convert into an Invoice.
