What I like best is the document builder features. The structure they gave to the product with the Templates and the content library I think is very useful because it lets you slightly change each document on specific sections which is something that happens a lot. I mean, templates work as a baseline document and then you can have multiple content library items that you pull in when needed.
There are key features that I feel are missing. Nonetheless I have spoken to them several times and they've said to me that all of the features I mentioned are already on the roadmap of the product, in fact they delivered one of those in the last update. Things like document signature deadline, live collaborative document editing, task/comment assignment to other team members when building a document. Those three are the key missing features.
The most important part of the process is to create the content library and the templates before sending the sales reps into it. Otherwise they'll sing in and won't know what to do. That was important for me during the on-boarding. Additionally don't forget to integrate it to other tools like your CRM.
The one thing we are solving is the way we are building and sending out comercial proposals. With Pandadoc we have everything organized and all the documents in the proper folders, so you can go back to them easily and see what's happing with the document. Also all the different templates already built in makes it very easy for the sales reps to build proposals in no-time.
Additionally the Human Resources Department is using Pandadoc for employee documentation. We've been using it as the formal company's employee documentation platform and it's been great.
