Private area + documents upload

Hi!
I need to create a site where digital products will be sold (eg tax declaration.).
Once purchased, the customer must be able to upload files which, however, will remain in his reserved area without time limits.
The files can be viewed by the owner and admin only, as they are private files.
Specifically, the files that the user will upload are the files required by the agency to fill in the purchased product. Example, if the customer has bought the tax declaration, he will be asked to upload his identity card, the expenses of the current year, etc.
It would be useful if the admin received an email notification once the required files have been uploaded.
PLUS but not mandatory:
– it would be ideal if the user were asked for only those necessary documents relating to his purchase.
– It would be useful to divide the “documents” section of the reserved area into tabs (identity card, tax code, driving license) or in another way, so as to keep everything in order.
Do you think your great plugin can cover all my needs?
Thank you!
