Proposals
DocSend is primarily a document sharing platform. As such, it doesn't offer you any proposal templates. And while it does make it easier for you to get your proposals sent and signed, it doesn't save you time during the creation process.
On the other hand, Better Proposals has over 200 pre-written and pre-designed templates ready for you to use. In addition to that, all the templates are customizable, so you can modify them to make them your own. And if you're wondering about digital signatures, Better Proposals offers them as well.
