You can link Google Drive documents to any record in VTiger. AND you can sync your Google Drive folder system into Vtiger. As long as your folder name in Google Drive matches an organization name in Vtiger, all the docs in that Drive folder will be created under that VTiger organization. As documents are created in Google Drive, they sync to Vtiger — a cron job controls how often the sync happens or it can be run manually on demand. Note: it is the google Drive doc link that syncs, not the actual doc — which is perfect because the docs are better stored in a centralized place.
The document permissions can be managed in google drive as well as in Vtiger.
