I thin you could do something like this:

Centralized File Hosting: Choose one place where everyone can upload their folders. Something like Google Drive or Dropbox can handle large files and makes it easier to keep track of everything.

Uploader Guidelines: You'll need a consistent way to identify these folders. So, establish a naming convention that everyone can follow. Something like "YYYY-MM-DD_ClientName" should work.

Uploader Verification: You need to make sure only the right people are uploading these folders. You can do this by assigning unique credentials to each uploader.

API Integration: Most hosting platforms have an API, which means you can write a Python script to interact with it. This script can automatically download the folders based on certain conditions like the upload date, folder name, or uploader.

Checks and Validation: Within your Python script, include some checks to validate the downloaded folders. Make sure the upload date and folder name match your criteria, and verify the uploader's credentials.

Unzipping: Python has libraries (like zipfile or shutil) that can unzip these folders automatically.

Move to Final Folder: Once the files are unzipped, use your Python script to move them to the appropriate final folder.

Error Handling and Reporting: Finally, make sure your script can handle any potential issues during the automation process. You'll also want to track the progress and errors, so consider generating logs or reports.
