Scrolling with more whitespace vs Everything on one page

Our end-users are used to an old B2B application which contains really small inputs and information that is so close together that it is difficult to distinguish. As a result, users complain a lot about the readability and findability of items in our web application. (Example: first image is old situation)

Therefore we tried to increase the size of our inputs, fontsize and space between items. We also logically grouped content (there are 3 groups of information). Because of these changes, everything is set up more spacious and the readability and findability has increased. However, now users complain that they have to scroll extra, where they used to see everything at a glance (Example: second image is the new situation).

How should we deal with this situation? Our pages contains a lot of information and I have the feeling that we have to choose between no scrolling or bad readability and findability.
