Clients (end users) will always have access to the cards and process rules you have created (or installed) in their Supered account.
If they choose to part ways, you as a Partner will be able to give them Admin access that will allow them to edit existing cards/process rules and create new ones moving forward.
We will keep them as a managed instance in your Supered account to track any revenue generated for the partner commission.
They will need to assume any licensing fees.
