I would highly recommend it to perform Programmatic API access to basically create your own personal and secure E-doc signing facility. if you're a big firm and requires all the business logic withing the confine of company policy and governance, Assently E-Sign should be a NO BRAINER. additionally it has clean API documentation as well.
Our use case for Conga Sign is pretty straightforward. Because of this, there is not much about it that would be considered excessive or inappropriate. It suits our needs as a tool to record data provided by a signer. It can also be launched from inside Salesforce via a custom button for ease of use.
We're a relatively high-skilled team and we all find Conga Sign's user-friendliness very low for all user types. It should not take a highly skilled tech person to complete documents. Documents need to be user friendly for all user types.
one line answer would be API Access, compared to all the other alternative Assently E-Sign fits well within our company use case, ease of use was also a deciding factor. once we implemented the custom E-sign using our API implementation, we did not had to look back. its working smoothly ever since without any complain.
Conga Sign is much more affordable than DocuSign for our organization and we are using Conga Composer already to create documents. We found that the integration between Conga Composer and Conga Sign was easier to use and we have a nice discount from Conga due to us adopting several of their products. DocuSign for the price point didn't make sense to us and it has less write-back functionality with Salesforce.
