Pay by Scan Business Model

Hello all,

Has anyone modeled Pay-by-Scan business model in Sage? It is basically consignment shipments - where you ship your products to your customer but you do not get paid until that product is sold at the store. So, you can not invoice the customer as soon as ship them something and until it is sold at their store, it is basically your inventory. 

It is a very complex and interesting problem to solve.

Thank you,
