Inventory cost used for product/sales orders

Hello, (9.2, 8.61, Image 55)

As an organization, we release items from our inventory at our own cost to third-parties that then they are supposed to reimburse us for jobs they perform. This has been done manually for a long time.

I was researching using Order Management and Sales Orders to formalize this process by having them "buy" the material and invoice/account via Billing and AR. I cannot seem to get the products I've created to have prices derived from our inventory cost. Is that even possible?

I tried setting the pricing rule to cost and it did nothing. Only list prices hardcoded to a value works for me.
