Invoice/Cost sheet concept
As a user, no matter where I go in your app, the overarching question for me is What do I need to know most/first?
If I came here, what is it I came here for? You have to delineate the Primary and Secondary information (A.K.A visual order of importance) on each screen to remove any ambiguity in your user experience.
Ambiguity causes frustration and has a cumulative effect on the churn.
