Every Kubernetes cost tool tells you roughly what each team spent. CostOptix tells you what Finance actually paid.
After discounts, reservations, spot and negotiated pricing, those numbers reconcile to your cloud invoice, to the cent. We call it invoice-reconciled chargeback, and as far as we can tell, nobody else self-serve does it.
If you have ever argued with a team lead about their cloud bill, this is the entire product.
Why an estimate is not a bill
Cloud bills already contain the truth. We think chargeback should start there, not with an estimate.
Most tools produce an estimate: metrics multiplied by list price. Finance cannot use an estimate. It never matches the bill, someone explains the gap every month, and eventually nobody trusts the number.
CostOptix closes each month by scaling every team's attributed cost against the real invoice. Discounts, savings plans and spot pricing are absorbed automatically. The team bills sum to your amortised invoice exactly, and the month-close job refuses to seal a bill that does not balance.
Once sealed, a bill is immutable. The number you sent a team in March still reads the same in September.How invoice reconciliation works
What you get on day one
No onboarding project, no professional services. Connect an account and these are live.
One view of every cloud
Azure, AWS and GCP accounts, Kubernetes clusters, hosts and Claude Code usage in one place, with each dollar counted once. Amortised cost by default, so reservation purchases never look like fake spikes.
Anomalies with receipts
Detection adapts to each service's history and catches new services going from zero to real spend. When something fires, a deterministic pass ranks the exact resources that changed by dollar impact before any AI writes a word. The full resource list is filterable and exportable.
Budgets that explain themselves
Every budget projects its breach date and, when it comes under pressure, names the resources pushing it there, each flagged as a spike, a new resource or steady growth. "We are going over" arrives with "and here is why" attached.
Kubernetes chargeback that reconciles to the invoice
Idle capacity is redistributed, unclaimed workloads are surfaced instead of dropped, and attribution follows workloads through pod churn. Then invoice reconciliation makes it real money instead of an estimate.
Team bills for cloud accounts too
Teams claim cloud spend by tag or own a whole account. Spend nobody claims stays visible as unassigned instead of disappearing, and each month closes into a sealed bill.
Savings that are checked, not claimed
Rightsizing, idle and orphaned resources, plus savings plan and reservation recommendations for AWS and Azure. Once you act on one, the bill is checked afterwards and the saving is marked verified or regressed.
Unit economics, not just totals
Divide spend by customers, orders or requests, for the whole organisation or one team, and lock closed months so the figures never move. On Business, revenue comes in from Stripe each day to show infrastructure cost as a share of it. Revenue is encrypted, admin only, and every view or change is in the audit log.
Who should buy something else
We would rather lose you in thirty seconds than after a wasted trial. This is the list today; it shrinks as we build.
The full list of what we do not do yet, with named alternatives for each gap, is on the comparison page. What we don't do
Pricing that does not punish growth
Business and Enterprise are quoted. Percentage pricing means the tool bills you more precisely as your cloud bill grows, which is the moment you most want to cut it. We do not do that.
The honest counterpoint: percentage vendors usually bundle a named FinOps advisor who reviews your spend monthly. We do not sell that. If you want a human in the loop, that is a real reason to pay them instead.
Where we fit, in fifteen seconds
We have not found another self-serve product that combines the first five rows. The last two are real gaps today, and we name who fills them, because a comparison you cannot lose is not a comparison. As those gaps close, this table gets updated, not quietly rewritten.
Built for the team without a FinOps team
CloudZero, Cloudability and Finout are more capable than we are. They also assume an annual contract, a quoting cycle and a bill that grows with your cloud bill. If you have FinOps headcount and seven figures of annual cloud spend, talk to them.
CostOptix is for the band beneath: real multi-cloud spend, often with Kubernetes in the middle of it, no dedicated FinOps function, and a need to know what changed and why this week, without a procurement cycle.
