AI Spend Audit
The AI invoice arrived. You don't know who spent what.
P402 runs a one-time audit of every AI call your organization made: owner, workflow, model, provider, tokens, cost, so finance can finally tie spend to ownership.
For CFOs, controllers, and FinOps leads who need to attribute AI spend before the next quarterly close.
The problem
Provider invoices show totals. They don't show ownership.
OpenAI, Anthropic, and Gemini bills arrive as a monthly aggregate. There is no department, no employee, no workflow, no project ID. Finance has the number but not the story.
Engineering teams paste API keys into shared services. Customer-facing features call models on behalf of customers who never see the underlying token cost. Both flows show up in the same total.
What P402 does
One ledger. Owner, budget, policy, outcome, evidence.
Owner, department, employee, customer, workflow, project, feature: recorded at the moment of the call. Not reconstructed from invoices weeks later.
P402 audits the economic event, not the prompt. No PHI, no PII, no source code leaves your environment. Audit safe for regulated industries.
Every event ships with a verifiable receipt: model, tokens, cost basis, policy decision, retention window. Exportable as a finance-ready bundle.
Audits OpenAI, Anthropic, Gemini, Bedrock, OpenRouter, and any HTTP-callable model behind one ledger. One report, every provider.
Proof
From first API key to first attributed event in the ledger.
Metadata-only mode persists no prompt or response content.
Default retention; configurable by tenant.
Questions
ai spend audit: FAQ
How long does an audit take to set up?
Routing audits start when you point your existing OpenAI-compatible client at P402. Meter-only audits start when your backend POSTs economic events. First event lands in the ledger within minutes.
Do we have to give P402 our prompts?
No. Metadata-only is the default. P402 receives owner, workflow, model, tokens, cost, policy decision, outcome, and evidence status. Never prompt or response content.
Can we audit historical usage?
Yes for any provider that exposes usage exports (OpenAI, Anthropic). We import the historical events into the same ledger and apply current attribution rules retroactively.
Is the audit a one-time engagement or ongoing?
Either. The one-time AI Spend Audit produces a delivered report. Same plumbing left running becomes a live ledger for the Meter / Monitor / Optimize surfaces.
Who owns the data?
You do. P402 is the recorder, not the owner. Export the full ledger at any time; delete a tenant's data on request.
