Chargeback Policy

A ChargebackPolicy property references a document describing how an API provider or internal platform allocates and recovers costs across teams, cost centers, or business units — including chargeback (actual cost transfer) and showback (visibility without transfer) methodologies. Chargeback and invoicing are formal capabilities in the FinOps Framework. Publishing a chargeback policy makes internal billing transparency discoverable, especially important for platform APIs used across multiple organizational units.

Also known as: Cost Allocation Policy, Showback Policy, Internal Billing Policy

Media Types

text/html — Most chargeback policies are published as human-readable documents.
application/json — FOCUS-aligned cost data is typically delivered as JSON or Parquet.
text/csv — FOCUS billing datasets are commonly distributed as CSV.

Governance Rules

info-contact (Spectral built-in) — Cost-allocation disputes need a documented owner.
tag-description (Spectral built-in) — Tags that drive allocation (cost-center, team, env) should carry explicit descriptions.

Risk & Compliance

Compliance:

SOX — chargeback affects intercompany accounting and revenue recognition controls
GDPR — cost reports tied to individual user usage may contain personal data
IFRS 15 / ASC 606 — intercompany cost transfers must be auditable
SOC 2 CC4.1 — monitoring of internal financial controls

Security: Cost-allocation tags often leak organizational structure, project codenames, and customer identifiers. Restrict access to detailed cost-and-usage reports the same way you would treat HR or revenue data.

Suggested Metrics

allocated_cost_ratio — Share of total spend that is attributed to a named cost owner.
untagged_spend — Spend that cannot be assigned to a cost center — the "shame metric" in FinOps.
chargeback_dispute_rate — Share of monthly invoices internal teams formally dispute.
cost_per_team — Recovered cost grouped by team / business unit.
showback_coverage — Fraction of services that publish a showback report.

Example Implementations

AWS — Cost Categories + Cost Allocation Tags drive chargeback across linked accounts.
Google Cloud — Billing labels and folder hierarchy feed chargeback reports.
Microsoft Azure — Management groups and tag inheritance support enterprise chargeback.
Snowflake — Resource monitors and warehouse-level usage support per-team chargeback.
