I am searching for a software based solution to enable customers to login into a space in which documents are exclusively stored for them to view and download and that the company is able to communicate 1:1 via chat or messages within this space.
The solution should be SaaS and the data is confidential. So it should be a professional solution. The customers are created by the company itself manually or with a registration form. The upload of the documents is done by the company without any automation. When uploading new documents or new messages are written, the user should be informed via email.
Is there any simple and easy solution on the market which meets these requirements?
