We sell SEO and related online marketing services, which tend to have a long list of deliverables. This is not such a big deal when the proposal is only for a single service. However, when a prospect requires more than one service (ex: web design, SEO and PPC), this can make a proposal extremely long and that is very overwhelming to the prospect (we have surveyed this and it was nearly unanimous). A great way to keep complex proposals very neat looking would be to use content accordions. And they need to be able to accept many types of content, including tables. Lastly, we should be able to style them as desired to match the proposal.
