I'm trying to see how to best use this system for our business needs.  Our client's prepay for their product and once we receive payment we begin working on their request.  At that point we request the product from our agency but not as a drop ship and there is a custom form our agency needs to receive, not the system purchase order.  we do not maintain inventory, this is more of a 'print on demand' situation.  how can i utilize your system for this?
