Which GCP SKUs am I spending the most on?

SELECT
  service.description                                        AS service,

  -- Committed-use and sustained-use discounts arrive as credits, not as a
  -- lower cost, so the rate that shows them is the one after credits.
  ROUND(SUM(cost)
    + SUM(IFNULL((SELECT SUM(c.amount) FROM UNNEST(credits) c), 0)), 2) AS net_cost,
