Anthropic billing is a single API invoice. Keito gives engineering teams a structured place to attribute Claude usage and cost to specific client engagements — not just to a monthly Anthropic bill.

Anthropic API cost tracking needs more than a timer. The billing record has to keep client, project, approval, and invoice context together before the work reaches finance.
Record token fees, subscription usage, and compute costs against the client project they serve as the agents run — not reconstructed at billing time from company card statements.
Combine AI agent cost records with human billable hours in one review so the total delivery effort is visible before the invoice cycle starts.
Use reviewed human and agent cost data to prepare client summaries and invoice backup that reflect how the work was actually delivered.
Claude cost attribution
Anthropic billing arrives as a single monthly figure for Claude API usage — input tokens, output tokens, and any premium model surcharges aggregated across every key in the account. For an engineering team building a single product on the Claude API, the bill is straightforward. For services teams and AI consultancies running Claude calls on behalf of multiple client engagements, the same flat bill obscures the picture: a $4,200 monthly Anthropic invoice has to be attributed to client engagements, sometimes broken into billable spend and internal R&D spend, and reflected somewhere in client invoices or margin reviews. Without structured attribution, the cost ends up handled as overhead and quietly erodes margin on AI-augmented engagements. Keito gives engineering and AI services teams a structured place to attribute Anthropic API spend to client engagements. Claude API costs are logged against client and project with token, model, and call-type context; approval queues catch missing attribution before any cost informs an invoice or margin review; and finance — or the engineering lead wearing the cost-review hat — works from a reviewed record rather than a CSV export from the Anthropic console. The result is Claude spend that reaches the right client engagement rather than disappearing into general overhead.

Keito tracks AI agent costs against the same client and project structure as human billable hours so agent spend is never invisible overhead. Agent sessions land as source-tagged time entries via the CLI, API, or Agent Skill, with LLM token costs logged as expenses.
See total delivery cost — human hours and AI agent costs together — by client and project so pricing, margins, and billing decisions reflect the real cost of work.
Keito flat pricing means adding AI tracking capacity to the billing workflow does not create a per-seat cost spike as more people and more agents are involved in delivery.
The difference is not just recording time. It is whether the record can support billing, project decisions, and client conversations.
Anthropic spend attribution
Keito keeps Anthropic API cost tracking tied to clients, projects, billable status, approvals, and billing summaries in one workspace.
Typical setups capture time in one tool and rebuild the billing explanation later from exports, comments, or spreadsheet cleanup.
Review before invoicing
Managers review entries before they become invoice evidence, so missing context is fixed internally rather than during a client dispute.
Raw timer exports usually reach finance before delivery leads have confirmed whether the work is billable, complete, or client-ready.
Predictable team pricing
Flat-rate plans let delivery staff, reviewers, contractors, and finance users participate without per-seat pricing friction.
Per-seat time trackers make teams choose between clean billing participation and controlling tool spend.
Use a workspace where time is captured against the right client and project, reviewed before invoicing, and exported as billing evidence. Keito is built around that workflow, so Anthropic API cost tracking is not separated from the approval and invoice context it needs.
Yes. Keito tracks work by client, project, person, billable status, and review state, then turns approved records into client-ready summaries. That makes it useful when Anthropic API cost tracking needs to support billing, profitability, and client reporting rather than just attendance.
A generic timer records duration. Keito records billable context: who did the work, which client and project it belongs to, whether it has been reviewed, and how it should appear in billing evidence.
