The most useful thing about this software is its ability to integrate with other applications like Salesforce etc., it has an easy-to-use interface which makes creating new documents very simple. It's not free but there might be some trial version available for you to try out before purchasing the full package. I would say give it a shot. If you're looking to create customised and high quality documents in bulk, this is one of the best options available right now. We use advanced documents as part of our daily activities as we need them to keep track of all sales orders received from various customers across different countries.
