Tools
Reads your own data
Cloud Bill Diff
See what changed in your cloud spending, and how much came from usage versus your effective cost per unit.
Cloud Invoice Reconciler
Upload one month of your billing export, type the invoice total, and see what explains any difference.
Cost Allocation Score
Upload a billing export and get a score out of 100 for how much spend you can assign to teams.
Commitment Coverage Checker
See how much of your eligible usage commitments cover, how much you are not using, and which ones expire next.
FOCUS 1.4 Validator
Check a billing export against the FOCUS 1.4 standard and get every column that fails, with the rule it breaks.
Assessment
FinOps Maturity Assessment
Score your engineering team on 22 FinOps capabilities, set a target for each, and see where the biggest gaps are.
Cloud & AI Cost Readiness Assessment

How these tools fit together
Your file stays in your browser
Five tools read your billing export in your browser: an AWS Cost and Usage Report, a Google Cloud billing export or a FOCUS file. Nothing is uploaded unless you choose "Share for a review". If your CUR 2.0 export is Parquet, create a second export as CSV, or use the Athena query.
When the bill moves
Start with the bill diff: it shows which services changed, and whether you used more or paid more per unit. Paying more for the same usage usually means a commitment ended; the commitment coverage checker shows what ended or expires next. If the invoice and export disagree, the invoice reconciler finds the matching part of the file.
Allocation and data quality
The allocation score grades how much spend can be assigned to a team, and ranks fixes by dollars. The FOCUS validator checks that an export meets the FOCUS 1.4 specification.
KPIs and credits
The KPI calculator holds all 88 FinOps Foundation KPIs and scores seven straight from a billing file. The credits runway calculator shows when each startup credit grant stops paying.
How mature is your practice?
The maturity assessment rates your team on the FinOps Framework's 22 capabilities. The readiness assessment is shorter, 25 questions, and asks for a name and email before it shows the score.
Reference libraries
Pages behind these tools, one per column, recipe, pattern or SKU. They are worth reading on their own and they are what the tools above check against.

Two files compared, or every day reconciled.
Finitizer runs this analysis continuously across every account and provider, catches a rate change or a usage spike the day it happens rather than at month end, and routes each finding to the team that owns it.
