How To Create A Dropshipping With Cs Cart Multi Vendor

I run a marketplace where some products from vendors are delivered by us (site administration) and I am trying to organize within the CS Cart Multi Vendor structure a way to support this line of business.

Has anyone done something similar and could share their experience in this?

In our case, we produce book that are sold by our vendors in their stores and once a purchase is completed by a customer we produce the book and send to the final customer. The shipping cost and production cost are deduced from vendor commission.
