We have a product that contains features (Let's say feature A, B and C).
We are about to move it to production (a web application) for a certain client.
However, as per my boss, we will deploy the product to the client's premises. The client will also have the source code.
Now, my boss wants to restrict the features for that certain client. He wants to restrict the feature A, so that only features B and C would be available to the client.
So what are our options? How can we do this technically(restricting features) and in terms of licensing?
