A Big Batch of Productivity

You can send a batch of tax form requests to hundreds of contacts at once with just a few clicks. Track the status of each request as they are viewed and completed.

When a form session is complete, an official PDF of the form is generated automatically. Official documents ensure that you are ready with the documents and data you need for compliance.
