Usage analytics & chargeback.

Knowing you spend £2M on AI is the start. Knowing which department spent it, on what, and whether it generated value — that's the conversation that changes behaviour.

The problem we solve

AI spend lands centrally. Accountability doesn't.

When AI spend sits in a central IT budget, every department benefits but none bears the cost. The result is predictable: over-provisioning, low engagement, and no mechanism to redirect spend toward the use cases that actually deliver value. Finance asks which AI investments are working. The honest answer is nobody knows — because nobody has the attribution data to tell them.

Chargeback changes the conversation. When Engineering sees a £40K monthly line item for code-assist tools, and Marketing sees a £28K attribution for generative content, both questions change — which features are being used, which aren't, and whether the next renewal should look different. Cost visibility at department level is the governance lever that spend management alone cannot pull.

The challenge is data integration. AI vendors report at the seat or tenant level. Mapping consumption to cost centres requires connecting SSO identity data, usage telemetry, HR org charts, and finance allocation rules — none of which was designed to talk to each other. That integration is what we build.

SSO & identity mapping Multi-vendor consolidation FinOps-aligned methodology
What's included

Five work-streams. One outcome: AI spend owned.

Every Usage Analytics & Chargeback engagement covers these areas — scaled to the complexity of your vendor landscape, org structure, and finance processes.

Work-stream 01 · Weeks 1–3

Data integration & pipeline build.

We connect to every AI vendor's usage API, normalise their differing data schemas, and land consumption data in a single attribution-ready dataset. The pipeline runs automatically — no manual exports, no monthly spreadsheet reconciliation.

Vendor API integrations — Copilot, ChatGPT Enterprise, Claude, Gemini, GitHub Copilot, and embedded AI in Salesforce, ServiceNow, and Adobe
Schema normalisation — seat events, token consumption, task runs, and active-user signals unified into a common usage model
Finance system alignment — cost data tagged and formatted for ERP ingestion from day one
Data validation layer — anomaly detection flags outliers before they distort chargeback calculations
Multi-vendor, single source

Identity & org mapping.

AI usage data identifies users by email or directory ID. Translating that to cost centres requires linking SSO identity to HR org structure — and keeping that mapping live as people move teams, join, and leave.

SSO directory integration — Azure AD, Okta, or Google Workspace linked to pull live user-to-department assignments
HR system sync — HRIS org chart imported to handle matrix structures, contractors, and shared-service teams
Cost centre tagging — every user's AI consumption tagged to the correct finance code in real time
Change management — joiners, movers, and leavers handled automatically; no manual reconciliation at period-end
SSO + HR org alignment

Chargeback model design.

Not all AI spend maps cleanly to one department. We work with finance and business unit leads to design allocation rules that are accurate, defensible, and simple enough that departments can understand their bill.

Showback vs. chargeback framing — determine which cost centres receive informational reporting vs. actual budget transfers, staged to your finance team's readiness
Shared-service allocation rules — enterprise-wide licences (e.g., a Copilot E5 bundle) split proportionally by active usage, headcount, or negotiated fixed share
Threshold and tolerance rules — minimum consumption floors that prevent noise from generating micro-chargebacks
Finance sign-off workflow — draft rules reviewed with finance controllers before go-live; fully documented for audit purposes
Finance-approved rules

Reporting & dashboards.

We build the reporting layer that makes chargeback data actionable — from executive-level spend summaries to department-level drill-downs that business unit heads can navigate without analyst support.

Executive dashboard — total AI spend, month-on-month trend, top-five departments by cost, and headline ROI indicators
Department view — self-service drill-down by tool, team, and individual user; consumption vs. budget; and license utilisation rate
Finance export — period-close chargeback pack with cost centre codes, variance commentary, and ERP-ready data file
Alert configuration — threshold alerts when department spend exceeds agreed budgets or usage drops below the dormancy threshold
Executive & BU views

Governance & ongoing cadence.

Chargeback only drives behaviour if it runs consistently. We hand over a governance model — monthly reporting rhythms, allocation rule review cadence, and a process for onboarding new AI vendors as they enter the estate.

Monthly period-close pack — automated chargeback report generated and distributed to finance and BU leads within 48 hours of period-end
Quarterly allocation review — chargeback rules revisited with finance and IT as the vendor landscape and org structure evolve
New vendor onboarding — integration playbook for adding any new AI tool to the attribution model within one billing cycle
Optional managed service — Proteam monitors data quality, resolves integration issues, and provides monthly commentary on spend trends
Monthly review rhythm
How we work

A four-stage delivery model. Live reporting in eight weeks.

Usage Analytics & Chargeback engagements typically run six to ten weeks from kick-off to first live reporting cycle, depending on vendor count and integration complexity.

01

Scoping & discovery

We map your AI vendor landscape, identify the data sources available per tool, review your finance and HR system architecture, and agree the chargeback model boundaries with finance stakeholders before a line of integration code is written.

02

Integration & mapping

Vendor API connections built, identity mapping configured, and the first round of attribution data validated against known spend figures. Discrepancies investigated and allocation logic refined until numbers reconcile to within agreed tolerance.

03

Chargeback model & reporting go-live

Allocation rules signed off by finance. Dashboards deployed. First live chargeback period run end-to-end — period-close pack produced, reviewed with finance, and distributed to business unit leads. Adjustments made before second cycle runs.

04

Handover & managed cadence

Governance model documented. Internal team trained on dashboard navigation and monthly close process. Optional ongoing managed service for data quality monitoring, new vendor onboarding, and quarterly allocation rule review.

Proof

What accountability changes.

"Until departments could see their own AI bill, every renewal conversation was abstract. The moment chargeback went live, usage patterns shifted within a single quarter."

Adjacent services

Often deployed together.

Usage Analytics gives you the attribution layer. AI Spend Management gives you the optimisation levers. Most enterprises deploy both within the same programme.

Ready to talk

Want to see where your AI spend is actually going?

Most finance teams we speak with are reconciling AI costs manually in a spreadsheet — or not reconciling them at all. The free consultation covers your current vendor landscape, the integration complexity for your specific stack, and a realistic view of what chargeback reporting would look like in your environment within eight weeks.

What you'll get

  • 30-minute call with a senior AI analytics specialist.
  • Assessment of integration complexity for your specific vendor stack.
  • View of what chargeback reporting would cover in your environment.
  • Honest read on whether external build support is warranted.
