Thanks all for the replies.

@WestCoastFunding - The API is exactly what we were looking into, but as you mentioned, the costs can add up really quickly. For example, we spoke to DocuSign, and they were quoting prices as high as $4/envelope and with massive volume, $3. That is crazy if you expect to have even minimal volume. Do you use it on all applications, or only a select few? And is this simply a high price, and there are less expensive options?
