For each job you create in LSP.expert, you can upload files from Dropbox, Google Drive, OneDrive or your computer.
In the job details, there is a Files tab.
To add a file, click on Upload and choose from where you would like to upload the file.
You can upload as many files as you wish for a job. Note that LSP.expert will never overwrite any files, so if you upload a new version of a file, the system will always keep a trace of the old one.
Once a file has been uploaded, you can click on the three dots at the end of the line to download or delete it.
You can also share the files you uploaded for a job with the supplier(s) to whom you outsource the job. For this, please see this article: https://help.lsp.expert/en/articles/3342946-how-can-i-share-files-with-a-supplier.
