Is Huddle your way of managing projects and team collaboration? Do your partners use SharePoint for the same purpose?
Did you find it annoying to send the files back and forth all the time? Would you find it easier if Huddle and SharePoint could cooperate (could be interconnected)?
The Pontibus Huddle - SharePoint connector is build to connect your businesses. It gives users an option of sharing the documents from Huddle to SharePoint.
Once you do this, the updating of the documents will be much easier.
