@mizpah : A process worth considering: When you are pre-paid by your customers, create a "Customer Payment" record to record that payment (using Page:Accept Customer Payment). The "Customer Payment" record should have a GL impact which typically hits "Undeposited Funds" and A/R. You will also find that customer record should show a "Credit" in Netsuite. Once you've fulfilled the actual order, you can then "Apply" the customer payment to the appropriate invoice. Depending on your business model, this may also be a good time to move the funds from "Undeposited Funds" into an income account, which would allow you to RevRec at the time of fulfillment.
