Processing Collaborative Bidding Events Using cFolders 
You can use this business process to create RFx and to integrate them in a document storage functionality that is managed in cFolders. This document storage functionality supports RFx for complex technical products requiring specifications and plans.
As a purchaser, you create an area in cFolders, which is accessible to all your bidders. In this area, you store your documents and specifications.
When bidders submit RFx responses, a separate area of cFolders is created, which is accessible only to you and to the respective bidder. In these areas, bidders store the plans and documents that they have produced in response to the RFx.
