Box is the best overall document storage solution in the market right now. It has a number of really important/great features:
1. Version Control - the ability to lock a document for version control, and the ability to see and manage past versions, including reverting to one.
2. Live collaboration - the integration with Office Online and Google Docs means you can work live in a document with the tools you love and know already, with other users.
3. Great user interface that is clean and easy to use. It has features like favorites, recents, tags, bookmarks, presenter mode, and others that make using the tool easy.
4. permissions are built to enable both control and sharing without too much effort.
5. The ability to see views and other data/metadata about the documents you store is also very nice.
6. Box Notes is a nice notes tool that has templates and a simple/easy to use interface.
7. Integration with other apps and tools makes it extendable and usable in non-standard ways as well.
8. The new Box Drive is very nice, with an up-to-date, streaming file approach.
There is not much I really dislike, but I do feel like Workflows and automation could use some attention. Also, a few features I would like are:
1. Ability to customize folders to appear different - right now all shared folders look the same. If I could give them different colors, etc, it would be nice. think adobe lightroom.
2. Would love to be able to create custom views of folders and files, with my own set of columns of info, etc
3. The ability to drag and drop and set the order in which folders appear in a view, without having to manipulate folder names
4. Would love a few more tools in Box Notes.It would be my dream for Box to buy Notion and integrate the two (might not be everyone's favorite, but that would be awesome for me).
5. Better comments and reviewing features would be nice - to be able to put viewable notes on top of a document without having to edit it, for instance - inline. Would be awesome.
6. Ultimately, I would love to see it incorporate more of a wiki flavor into the site as well, so both kinds of documentation could reside in the same place. But that is my own crazy dream.
Don't just jump in and start throwing files and folders in. Deliberately architect its organization, permissions, etc before starting. It will make it much better (as with any tool like this).
I have used Box in several companies now. It helps keep documents centralized, share inside and outside the organization, makes documentation accessible and easy to collaborate.
