Estimate AI gross-margin inputs by account

How does accepted-output cost compare with successfully collected revenue for each account?

Join account-level model cost and accepted outcomes to billing results without treating analytical estimates as invoice truth.

Read-only SQL

WITH ai_usage AS (
  SELECT
    account_id,
    ROUND(SUM(estimated_cost_usd), 4) AS estimated_ai_cost_usd,
    SUM(CASE WHEN accepted THEN 1 ELSE 0 END) AS accepted_outputs
  FROM llm_requests
  WHERE status = 'success'
  GROUP BY account_id
),
collections AS (
  SELECT
    account_id,
    SUM(CASE
      WHEN event_name = 'invoice_paid' AND status = 'success'
      THEN amount_usd ELSE 0
    END) AS collected_usd
  FROM billing_events
  GROUP BY account_id
)
SELECT
  a.account_id,

How to read the query

Model usage is reduced to one account row before the billing join.
Cost per accepted output uses a reviewed product outcome rather than provider success alone.
Accounts without collected revenue remain visible with a null cost percentage instead of an invented infinite margin.

Decisions the SQL cannot make

1Use versioned provider prices and reconcile estimates with provider invoices.
2Define accepted outcomes per feature and guard against missing feedback.
3Include non-model infrastructure and labor costs before claiming gross margin.
