Making documents together. Google Docs work with spreadsheets, presentations, forms, and more. Using comments, you can leave a note on someone else's work to request a change or leave yourselves a note for later.
Part of Google Docs is Google Drive, which lets your team set up your own file storage system. With 15 GB of free space. (If the default set of features that Drive provides isn't enough for you, a host of apps can fill in the voids, like annotation apps that boost collaboration potential).

Slack allows you to share any file.
Using Slack for communication is superior to emailing back and forth all the time or using a group chat in WhatsApp. Both of those are hard to follow and don't scale well with more team members.
With threaded conversations, @mentions for different groups, the ability to place calls from within the app, and powerful search.
