Claude
You decide
FinOps and finance decide whether and how much to commit.
Why it matters
Commitment decisions are made once a year in a spreadsheet, while usage keeps moving. Under-coverage wastes money; over-commitment locks it in.

FAQ
Questions about this playbook
Does Costory purchase Savings Plans or Reserved Instances?
No. Costory shows coverage and helps you size options; purchases stay with your team.
Why do team costs change after a Savings Plan purchase?
Discount sharing moves billed cost between accounts. Contracted cost gives teams a stable, usage-driven view.
Does Costory guarantee savings?
No. The agent investigates and recommends with the evidence attached; your team decides what to change. Impact figures are estimates based on your own data.
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.
