Sharing Documents for Editing and Commenting

I wanted to know if Airbase provides the capability of sharing specific documents (PDFs, Google Docs, Images, etc.) with specific people outside the team (i.e. Clients) so they can provide edits, feedback and review? My agency needs a tool that manages the gathering of feedback and edits through an easy to collaborate platform. Currenlty we use SmartSheets but there have been issues and limits. Thanks in advance.
