How Warren Averett Streamlined Electronic Signatures Inside Custom Applications

KEYSYS helped Warren Averett integrate DocuSign into its internal custom applications, creating a more efficient electronic signature process that allowed users to prepare, route, and manage signature envelopes directly from existing workflows.

The challenge

Electronic signatures needed to fit the firm’s existing workflows.

Warren Averett wanted to choose an electronic document signature platform and create a more efficient electronic signature process within its internal custom applications.

The firm did not simply need access to an eSignature tool. It needed that tool to work inside the custom applications employees were already using.

The business problem was not simply, “Can we get documents signed electronically?”

It was: How do we integrate electronic signatures into our internal systems so document signing becomes part of the workflow instead of a separate process?

The workflow looked like this

Create the client envelopeThe application needed to generate the signing envelope and prepare it for execution.
Automated

Warren Averett did not need a standalone signing tool that added extra steps. They needed an integration that made electronic signatures a native part of their custom application experience.

Why it mattered

Professional services teams need document workflows that are efficient and repeatable.

When important documents need signatures, every extra handoff adds friction. If employees have to leave an internal application, manually prepare a separate envelope, re-enter signer information, and track the process elsewhere, electronic signatures can still feel manual.

For Warren Averett, embedding DocuSign into internal applications created a more efficient path. It allowed users to initiate signing workflows directly from the systems where the work already happened.

The solution

A custom DocuSign API wrapper for internal applications

KEYSYS developed an API wrapper to integrate Warren Averett’s custom application with DocuSign, an electronic signature industry leader.

KEYSYS created a dynamic link library, or DLL, to execute the functions the application needed. This gave users the ability to specify the document to be signed, indicate the number of required signees for that document, and create the client envelope.

The technical stack included C#, .NET, and DocuSign.

Instead of creating a one-off connection, KEYSYS built reusable integration logic that could support Warren Averett’s document signature workflow inside its internal systems.

Key capabilities
  • DocuSign integration inside custom applications
  • Custom API wrapper for electronic signature workflows
  • Dynamic link library for reusable application functions
  • Document selection for signature routing
  • Configurable number of required signees
  • Client envelope creation
  • C# and .NET implementation
  • More efficient document signing process for internal users
How it works now

From disconnected signing to embedded electronic signature workflows

KEYSYS  ·  Warren Averett DocuSign Workflow
Choose the document

Users can specify which document needs to be signed from within the custom application.

Define signees

The application allows users to indicate the number of required signees for that document.

Create the envelope

The DocuSign integration creates the client envelope for signature routing.

Execute through reusable functions

The DLL handles the functions needed to connect the internal application with DocuSign.

What once could have become a separate electronic signing process now works as part of Warren Averett’s internal application workflow.

The impact

Warren Averett gained a more efficient electronic signature process

By integrating DocuSign into its custom applications, Warren Averett created a more streamlined process for preparing and routing documents for signature.

The new integration gives users a clearer way to choose documents, define signer requirements, and create client envelopes without relying on disconnected manual steps.

Better workflow efficiency
  • Electronic signatures are connected to internal applications
  • Users can initiate signing steps from the systems they already use
More flexible signing process
  • Documents can be specified dynamically
  • The number of required signees can be defined by workflow need
Reusable integration foundation
  • The API wrapper and DLL provide reusable DocuSign functionality
  • Warren Averett gained a stronger foundation for electronic document workflows
Before KEYSYS
Electronic signatures needed better application support
  • Warren Averett needed to select an electronic signature platform
  • Internal custom applications needed a more efficient signing workflow
  • Users needed a way to specify documents for signature
  • Different documents required different numbers of signees
  • Envelope creation needed to be handled through the application
After KEYSYS
DocuSign integrated into custom workflows
  • KEYSYS integrated DocuSign with Warren Averett’s internal custom applications
  • A custom API wrapper handled electronic signature functionality
  • A DLL executed reusable signing functions for the application
  • Users can specify documents and required signees
  • The application can create the client envelope directly

Ready to Embed Signatures Into Your Existing Workflow?

If your team uses electronic signatures but still relies on disconnected steps, duplicate entry, or manual envelope setup, you may not need another signing tool. You may need the right integration inside the systems your team already uses.
