Rank our top 20 tenants by allocated infrastructure cost last month and compare with their plan tier.
The top 3 tenants drive 22% of allocated infrastructure cost. Tenant acme-retail (Growth tier) costs €2,300/month, above its plan price. Most of it is search indexing triggered by their catalog syncs.

FAQ
Questions about this playbook
Do we need a tenant label on every resource?
No. Direct costs can use labels or namespaces, and shared costs can be split by per-tenant usage you push as custom metrics or read from BigQuery.
Where do business metrics come from?
From Amplitude, BigQuery, Snowflake, Google Sheets, S3, Datadog, CloudWatch or metrics you push to Costory's API.
How long does this playbook take to set up?
Connecting your billing data and the Costory MCP takes under 30 minutes with Terraform or CloudFormation. The playbook itself takes minutes: pick the scope, the trigger and the Slack channel. The first billing data lands the next day, and the agent starts from there.
Does Costory change anything in our cloud accounts?
No. Costory reads billing exports and the metrics you connect, and has no write access to your cloud. Actions it takes create Costory objects only: alerts, reports, dashboards and events. Your team stays in control of every change.
