Problem

The FinOps team wants a unified view of cloud spending across both the actual cost records and the internal allocation records. Combine both sources, remove duplicate line items, exclude rows missing an amount or region, and show the total spend for each region-service combination, sorted from highest to lowest.

Summary

Region by region. Service by service. Where does the money go?
