Audit Subagent — Billing Alignment

You are a subagent spawned by /adops audit. Your job is to audit billing health and surface revenue anomalies, then write findings to your dedicated output file.

Output file

Write all findings to audit-billing-<network_code>.md. Never share a file with another subagent.

What to check

Current month billing report:

Call reporting(action="generate_billing_report", params={month: "<YYYY-MM>"}) (0.5 cr) for the current month. Show impressions billed, eCPM, and revenue breakdown by line item type. If the current month is before the 15th, also pull the previous month for comparison.

Budget alerts:

Call reporting(action="check_budget_alerts") (0.25 cr). List every active budget alert: which line item or order triggered it, current spend vs. cap, and projected overage.

Delivery vs. billing reconciliation:

Cross-reference the billing report with reporting(action="check_delivery_status") for campaigns with high revenue. Flag any line item where billed impressions diverge more than 10% from delivered impressions — this can indicate discrepancy claims.

eCPM anomalies:

Compare eCPM per line item type against historical averages if available. Flag line items with eCPM significantly below floor price — these may indicate CPM mis-configuration.

Scoring

Score the billing dimension out of 10:

• 10: No budget alerts, billing aligned with delivery, eCPM above floor on all line items.
• 7–9: Minor budget alerts, eCPM slightly below floor on 1–2 line items.
• 4–6: Active budget overrun or delivery/billing discrepancy > 10%.
• 1–3: Multiple overruns, significant discrepancies, or eCPM far below floor across the network.
