AI BILLING

Bill for Reasoning, Not Just Requests.

Stop losing margins to opaque AI costs. Aforo provides the infrastructure to meter tokens, reasoning steps, and tool calls in real time — mapped directly to your provider COGS.

Every agentic transaction breaks down into prompt tokens, reasoning steps, tool calls, and completion tokens. Aforo aggregates all four into a single billable event — with cost attribution at the provider level. Turn opaque AI compute into defensible B2B margins.

TRANSACTION ANATOMY

One Agent Task. Four Cost Stack.

Traditional billing treats an agent request as a single API call. Aforo sees the entire trace — every token, every reasoning step, every tool invocation — and aggregates them into one billable event with full cost attribution.

Flat SaaS pricing + variable AI costs = margin collapse.
Aforo eliminates the equation entirely.

Every dollar of AI compute must be accounted for, marked up, and collected. Aforo gives Finance, Product, and Engineering a single system of record for AI unit economics.

Model-Agnostic Metering

Switch between OpenAI, Anthropic, or DeepSeek without changing a single line of your billing code. Aforo meters at the token level regardless of provider. When you migrate models, your pricing logic stays intact. Your billing code is decoupled from your AI stack.

Dynamic COGS Mapping

Aforo automatically adjusts your cost attribution as providers update their token pricing. When OpenAI drops GPT-4o prices or Anthropic launches a new tier, your margin calculations update in real time. No manual spreadsheet updates. No stale cost assumptions eroding your P&L.

Real-Time Entitlements

Kill a runaway agent session the millisecond it exceeds a customer's budget. Hard limits, soft warnings, and automatic throttling at the entitlement layer — before the cost hits your margin. Finance sets the guardrails. The platform enforces them. Engineering touches nothing.

HOW IT WORKS

From raw AI compute to defended gross margins

Four stages separate your vendor costs from your customer invoices. Each stage adds margin visibility, financial controls, and audit confidence.

01

Ingest Multi-Dimensional AI Usage

Raw telemetry

Capture tokens (input and output), model type, latency, agent sessions, tool calls, and session duration. One SDK decorator. Every dimension of AI compute is recorded at the event level with sub-second granularity.

02

Map Usage to Margins

Cost intelligence

Apply your markup rules, pricing models, and COGS tracking per model provider. Aforo calculates your actual gross margin on every request, every customer, every product -- not at month-end, but in real time.

03

Package as Enterprise Credits

Value abstraction

Abstract raw tokens into credits, tasks, or compute units that your customers understand and can budget against. Product managers define the exchange rate. Finance controls the markup. Customers see a simple balance.

04

Bill without Revenue Leakage

Automated collection

Automated invoicing with full audit trail. Every credit consumed, every overage charged, every discount applied is traceable back to the raw usage event. Zero reconciliation gaps between what was consumed and what was billed.

The margin control plane for AI products

Real-time dashboards that connect vendor costs to customer revenue at every level of your AI stack.

Who needs margin protection

Three stakeholders, one shared fear: AI costs growing faster than AI revenue.

VP of Product

Launching AI features into an existing B2B product

The problem: The board wants AI features shipped yesterday, but finance won't approve without a clear cost model. Every pricing discussion stalls because nobody can predict per-user AI costs with confidence.

WHAT AFORO DELIVERS

  • Credit-based packaging that product managers can define without engineering
  • Real-time usage dashboards to validate pricing assumptions before committing
  • A/B test pricing models against actual COGS data, not spreadsheet guesses

VP of Finance

Protecting gross margins on AI-powered product lines

The problem: AI vendor costs are the fastest-growing line item on the P&L. Current billing infrastructure has no visibility into per-customer cost-to-serve. Month-end reconciliation reveals margin erosion weeks too late.

WHAT AFORO DELIVERS

  • Real-time COGS dashboards mapping vendor costs against collected revenue
  • Automated quota caps and wallet balances that prevent margin collapse before it happens
  • Audit-ready invoices with full traceability from raw token usage to line item

Head of AI / ML

Managing multi-model costs across production workloads

The problem: Running GPT-4, Claude, and Mistral in production with no unified view of cost per call, model selection patterns, or per-customer resource consumption. The monthly cloud bill is a black box.

WHAT AFORO DELIVERS

  • Per-model cost tracking with input/output token breakdowns across all providers
  • Customer-level resource attribution so you know who drives cost
  • Model migration cost modeling -- see margin impact before switching providers

AI features should grow your business,
not destroy your margins.

Every enterprise shipping AI features needs a system that maps vendor costs to customer revenue in real time. Aforo is that system. Stop guessing at margins. Start defending them.
