Cloud storage for sharing documents with clients and partners

Cloud storage for external sharing needs reliable link-based access for people without an account on the platform, version history that survives a client editing a shared document, and a permission system simple enough to set correctly without regularly checking who can see what.

Google Drive's link-sharing is the most widely familiar to external recipients and integrates directly with Google Docs and Sheets for collaborative editing, which matters when a client needs to comment on or edit a document rather than just receive a finished one. Dropbox has historically had the most reliable sync performance for large files and folders, useful when reports or product PDFs run into the tens of megabytes, though its collaborative editing features lag behind Google's native document tools. OneDrive is the natural choice specifically when a team or client already runs Microsoft 365, since permissions and version history tie into the same account system as Teams and Outlook.

A team sending finished PDFs and the occasional editable document to external clients is well served by Google Drive by default. Dropbox is worth it specifically for large file transfer reliability; OneDrive makes most sense inside an existing Microsoft 365 relationship.
