HubSpot Sales Free users can access up to five documents per user. If a free Sales user is added to an account where five or more documents have already been uploaded, that free user will be able to view and use only the first five documents that were uploaded.
If you or a member of your team needs to access more than five documents, you can do so by upgrading to HubSpot Sales Professional or adding the user to an existing HubSpot Sales Professional team. Sales Professional allows you to create 1,000 documents per user.
At this time, there is no file size or storage limit to documents uploaded.
