In LSP.expert, you can add files at the client level. Reference material, confidentiality agreement and other important documents can all be stored at one place so you can easily find them back.
In the clients details, you'll find a Files tab.
To add a file for this client, click on 'Select file...'. You can choose from Dropbox, Google Drive, OneDrive and your computer.
Note that LSP.expert will never overwrite any file, so if you upload a new version of a file, the system will always keep a trace of the old one.
The File Manager allows you to quickly find the files you're looking for, to keep track of all the files (old and new versions) for a client and to access these files from anywhere, on any device.
