Sending a contract document for review and signatures, tracking the signed contract document and updating the contract record status, and automatically invalidating a contract document that is pending signatures if a new contract document supersedes it are three functionalities that are readily available with DocuSign integration. DocuSign is an eSignature solution that can be integrated with Public Sector Solutions without custom coding. It can help public sector agencies to send, sign, and manage contracts and agreements electronically. DocuSign integration can provide features such as sending a contract document for review and signatures to multiple recipients, tracking the signed contract document and updating the contract record status in Salesforce, and automatically invalidating a contract document that is pending signatures if a new contract document supersedes it using DocuSign PowerForms.
