Product · AI Spend Ledger
See what AI costs, and where the number came from.
Bring connected provider, billing, gateway, and expense records into one ledger. Review costs by owner, team, app, or agent, with unresolved attribution kept visible.
Cost authority
An activity signal is not a bill.
- Direct and allocated
- Keep provider-reported or billed costs distinct from amounts assigned through a shared-cost allocation rule.
- Estimated and attested
- Label usage-based estimates and team-supplied amounts. Preserve assumptions instead of making them look invoice-authoritative.
- Unresolved
- Missing cost or ownership stays unresolved. Unknown activity is not idle usage, and unknown cost is not zero.
- Freshness
- Check the source and refresh state before relying on a rollup. Provider API records can observe direct calls without gateway routing.
From cost to action
Use the record to make a decision.
- Review the project
- Bring assigned costs into AI Portfolio alongside measured results, missing evidence, and the next investment decision.
- Set a routed budget
- Apply actor budget alerts and automatic cutoffs to new gateway-routed requests. These limits do not stop provider-direct calls or license charges.
- Resolve attribution
- Ask the relevant owner to confirm shared-cost allocation or the project behind an expense before expanding the budget.
Supported sources
Start with the records you have.
Sources contribute different evidence. Billing can establish cost; usage can show activity; identity and discovery can add context without establishing a paid seat or exact spend.

- Anthropic telemetry
- OpenAI API telemetry
- ChatGPT Enterprise and Edu Workspace Analytics CSVs
- GitHub Copilot usage and seat telemetry
- Microsoft 365 Copilot usage via Microsoft Graph reports
- AWS CUR Bedrock billing with cost-allocation context where available

Bring the first cost record into focus.
Connect a supported source, review its cost authority, and confirm the owner before using it in a project decision.
