Why it matters
Finance needs stable month-end numbers per cost center. Engineering's live dashboards keep moving, so every month starts with a reconciliation argument.

FAQ
Questions about this playbook
What if our tagging is incomplete?
Costory's Virtual Dimensions allocate with rules on accounts, projects, names and partial tags, so you don't need perfect tagging to start. Shared and untagged cost is reallocated dynamically using the metrics you already have (Datadog, Tsuga, BigQuery, Snowflake and more), and the allocation stays consistent as usage moves.
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.
Can we adjust what the agent does?
Yes. You choose the trigger, the scope (team, service, environment), the channel and the format, and you can pause or change it at any time.
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.
