Paperless has a tracking method for paper copies as well; i think the idea is you assign an archive number, then file it in the expected place (for example, 2023-01 to 2023-500 would be one of the 500 docs you get a year, then you put it in the filing cabinet in order from 1 to 500 under 2023). Then you can still search for document by name tag correspondent etc. in paperless and find the archive number.
