Cost baseline

Builds the monthly cost per provider and service from the bills themselves. Each source is converted to FOCUS (FinOps Open Cost and Usage Specification) columns first, so every provider has the same columns. scripts/focus_export.py baseline then writes the tables and the flags. The page states the period and the source of every figure. The gate rule finops.cost-provenance checks that.

Inputs

• Sources (required): invoices (PDF or e-mail), billing exports (CSV), FOCUS exports, cloud cost exports, expense or card exports. Ask where they are. Raw billing files can hold account ids, names and addresses: keep them outside the repository, or in a folder the user names as private.
• Months: default the last 12 full calendar months, or what the sources hold. Use at least three full months.
• Owner: the person or team that keeps the page true.
• Page: default docs/fin/cost-baseline.md.
• Audience: whether the docs site is public. Ask before any amount, account id or contract term goes onto a public page.

Steps

1. Set up. Copy the templates without overwriting:
