Proper way to manage company wide Acrobat Standard

We have a customer who just purchased 6 Adobe Acorbat Standard 2020 licenses through Lenovo and I'm not sure the proper way to managed these for a business. 

Is there a way to add these to an admin portal so they can be centrally managed and re-assigned to users as needed? Do we redeam all of them under a single account to retrieve the serial number and just install via serial without signing users into Adobe accounts? Or do we need to make a personal adobe account for each user and redeam the license under that user?

Just looking for the proper way to proceed with this. I didnlt know perpetual licenses were even still sold. We typically just have customers purchase the necessary subscriptions via Adobe Business and manage them from the admin panel. 

Thank you for any assitance!
