We are implementing Netuite now and our current system is able to post Income and Costs of Sales for a non-inventory item on the same sales transaction (when it's billed).  Therefore, we can track our Income Statement almost daily and have an accurate representation. 

In Netsuite, it appears that the non-inventory item cost gets posted to COGS (or an expense account we pick) when the Bill is created for the PO.  Then, the income is recorded later when we Bill the customer.  We need these to happen simultaneously, or close to it, in order to track costs for large, multi-month projects.  We run into the same problem when using a non-inventory item on a work order/BOM.  Has anyone used a work around for this?  (Other than turning the one-time-only items into inventory items)
