Proposal Packs are included in a number of product bundles and sold as stand-alone products. Each Proposal Pack includes a variety of documents and features, each line item below is a document or feature in the Proposal Packs. Each column is what product(s) the line item is included in.
Example 1: The "Inquiry Letter" template (4th link down from the top) is included in all Proposal Packs and Proposal Kit Pro, however not in any other products.
Example 2: No Proposal Pack templates are included in the Contract Pack products, so that column will be empty.
