Standard Marketing Progress Reporting Needs

I have a significant gap in our NetSuite system. It centers around leveraging the data we already have in NetSuite to view the progress of our marketing campaigns. When I search the marketplace, all of the marketing applications involve customer communications, which we don’t want to use because we are using Klaviyo. I need intuitive reports to select items by (class, brand, cherry-pick) and view an itemized view of sales over a period of time with the ability to drill down (# sold, unit price, ext price. I would also like to run similar reports against customer demographics (aka, all customer who bought x). Can you see if there is such a tool that exists that could help us OR do we need to build these from scratch$$$. Our reporting needs are not unique, instead they are standard analytical report for marketing.
