Proposals and Multicompany
When you enable the Multicompany feature, you track proposals at the enterprise level, so that all proposals data is available to all companies in the enterprise.
Therefore, if you are building a proposal, you can search data for the entire enterprise to find relevant past project experience or to gather employee resumes. This shared information can be particularly helpful if two of your enterprise's companies are proposing to do a project together, or demonstrating how they worked together in the past.
