Documate is a great piece of software with unlimited functionality. The interface is easy to understand, and I love that I can add multiple documents to my output documents, so they all populate at once. I have one interview with over 30 documents with complex logic. They also provide custom services, which I've used a few times to set up SMS messaging and other special notifications. I previously tried HotDocs, which was so burdensome to learn. I was able to learn Documate with just a 5 minute demo from the customer service team, who is also awesome.
Super easy way to get perfectly formatted, error-free documents and document packets. The interface makes it easy to build simple document assembly for one document in 5 minutes, but it's also a very powerful engine for much more complex tasks.
