METERING ENGINE
Every Billable Moment.
Captured. Validated. Ready to Invoice.
Revenue leakage starts where metering stops. Missed events, duplicate charges, and unvalidated timestamps cost enterprise billing teams millions annually in write-offs and customer disputes.
Aforo captures every billable event from every source — gateways, SDKs, webhooks, REST, batch uploads — validates it against financial-grade rules, and delivers it to billing with full audit provenance. 100% accurate usage-based billing at enterprise scale.
Metering is the revenue foundation.
Get it wrong, and every invoice downstream is suspect.
Most metering systems count events. Aforo validates, enriches, and certifies them — giving your finance team the confidence to close the books without manual reconciliation.
Revenue Assurance
Every event passes through idempotency checks, timestamp validation, and schema enforcement before it reaches billing. Duplicate detection via configurable idempotency keys. Late arrivals flagged for reconciliation — never silently dropped, never double-counted. Your finance team can certify that every invoice traces back to a validated source event.
Financial Auditability
Full provenance chain from ingest to invoice. Every event carries its source, ingestion timestamp, validation result, enrichment context, and routing decision. Replay any billing period from raw events. SOC 2 and SOX-ready audit trails without building custom logging infrastructure.
Real-Time Cost vs. Revenue Mapping
Events are enriched with customer, subscription, and pricing context at ingest time — not at billing time. Know your cost-to-serve per customer, per product, per API endpoint in real time. Finance sees margin by cohort before the billing cycle closes. No more month-end surprises.
HOW IT WORKS
From source event to certified invoice in four stages
Every event carries full provenance. Every stage is auditable. No black boxes between your API traffic and your revenue.
Capture Usage Automatically
Five ingestion tiers — zero-code to full control
Gateway plugins intercept every API call at the network layer. SDK decorators instrument application code. REST endpoints accept custom payloads. Plugs receivers normalize third-party events. Batch uploads reconcile historical data. Pick the tier that fits your architecture — the pipeline treats every source identically.
Validate for Financial Integrity
Every event passes 4 validation gates
Timestamp validation rejects future events beyond 5-minute clock skew and events older than 90 days. Idempotency keys detect and reject duplicates. Schema validation ensures required fields exist. Late arrivals (>24 hours) are flagged for manual reconciliation — never silently dropped, never silently accepted.
Enrich and Map to Contracts
Billing context resolved at ingest time
Every validated event is enriched with the customer, subscription, rate plan, and pricing model it belongs to. Redis-cached entitlements (10-minute TTL) ensure sub-millisecond resolution. Events arrive at billing fully contextualized — no lookups required at invoice generation time.
Settle and Invoice
Deterministic handoff to billing pipeline
At period end, the billing engine consumes metered events already tagged with pricing context. Aggregation, rating, discounts, tax, and settlement happen in the 10-stage billing pipeline. Your team never touches the data between metering and invoice.
The metering infrastructure, in detail
Five ingestion methods. Four validation gates. One certified, auditable pipeline.
Built for teams that own revenue accuracy
Different roles, same outcome: every billable event accounted for.

Engineering tickets for new product metering
Your revenue deserves
financial-grade metering.
Stop writing off disputed charges. Stop building custom metering for every new product. Start with a pipeline that validates every billable event and traces it to the invoice.
