BILLING ENGINE
Execute the Math. Route the Revenue.
The Billing Engine ingests billable units, applies your active rate plans, manages prepaid wallets in real time, and generates pixel-perfect invoices — or exports pre-calculated line items directly to your ERP. Absolute financial accuracy at scale.
This is the execution layer. Metering captures the events. Pricing defines the rules. Billing does the math — rating, proration, drawdowns, discounts, tax, settlement — across a 10-stage deterministic pipeline. Use Aforo invoices natively, or route the calculated charges to QuickBooks, Xero, NetSuite, or SAP.
Execute the Math. Automate the Collection.
The Billing Engine is your deterministic revenue pipeline. It consumes processed usage data from the Metering Engine and applies the specific Offer rules defined in the Pricing Studio to calculate overages, manage wallets, and produce audit-ready output — either as native Aforo invoices with automated tax, or as pre-calculated line items exported directly to your ERP.
Four Execution Stages. Zero Manual Intervention.
The Billing Engine consumes metered events and Offer rules, then executes: rating, wallet management, overage enforcement, and invoice generation. Every stage is deterministic and produces audit-grade output.
Automated Rating & Proration
Raw metered events arrive already enriched with customer and subscription context. The Billing Engine applies the correct active Offer rules — per-unit rates, graduated tiers, volume thresholds — and calculates the charge. Mid-cycle upgrades, downgrades, and overage calculations are handled automatically with deterministic proration math. No spreadsheets. No Finance tickets.
Prepaid Wallet Management
Prepaid customers fund a wallet. Usage draws it down in real time with atomic escrow holds — pessimistic locking ensures no overdraft, no double-debit. Balance tracking updates per billing event, not per cycle. Automated threshold alerts at 75%, 90%, and 100% consumption. When exhausted, the engine blocks, throttles, or spills to arrears — based on the Offer configuration.
Native Invoicing & Automated Tax
At period close, the engine consolidates every charge — recurring fees, one-time charges, metered usage, proration adjustments, overage surcharges, and discounts — into a single finalized invoice. Tax is calculated automatically via integrated Vertex and Avalara tax engines for global compliance across jurisdictions. Failed payments trigger dunning sequences with configurable retry intervals and escalation rules.
Bring Your Own Billing (ERP Sync)
Already have a billing system? Aforo does the hard math — rating, proration, overage calculation, discount application, wallet drawdown — and exports pre-calculated, dollar-value line item records on a configurable schedule. Import directly into QuickBooks, Xero, NetSuite, or SAP. Your finance team keeps their existing tools and workflows. Aforo handles the usage-based complexity they cannot.
HOW IT WORKS
From metered usage to paid invoice in four stages
Every contract term is enforced by the pipeline. Every charge is auditable. Every invoice is deterministic.
Aggregate Usage Instantly
Metered events arrive pre-enriched with billing context
The metering engine delivers validated, enriched usage events tagged with customer, subscription, and rate plan. The billing pipeline aggregates by billing period, applies quota checks and rollover credits. No manual data export, no CSV reconciliation, no scripts.
Apply Custom Contract Terms
RateStage → CommitStage → DiscountStage
Six pricing models execute in the RateStage: per-unit, flat rate, percentage, included quota, graduated staircase, and volume-tiered. CommitStage enforces minimum spend true-ups and maximum spend caps. DiscountStage applies loyalty discounts and promotional pricing — all encoded in the rate plan, not in billing team spreadsheets.
Generate Tax-Compliant Invoices
TaxStage → RouteStage → SettleStage
Tax calculations applied per jurisdiction. The RouteStage decides the settlement path: postpaid customers receive invoices, prepaid customers see wallet drawdowns, hybrid customers split automatically. Every invoice carries line-item detail traceable to source events — ready for audit, ready for the customer portal.
Automate Collections & Reconciliation
Dunning scheduler + automatic recovery
Failed payments enter an automatic retry sequence with configurable intervals and escalation rules. Subscriptions suspend after maximum retries. Payment recovery triggers immediate reactivation. Finance sees a clean reconciliation report — settled, pending, recovered, and written-off — without chasing down individual transactions.
