From raw events to accurate invoices.
Send usage as it happens; GetPaidHQ aggregates it against the right meter and reflects it on the next invoice.
- Event ingestion
- Stream billable events via the API, individually or in batches.
- Aggregation
- Sum, max, last-value, and unique-count aggregation per meter.
- Usage summaries
- Query current-period usage for dashboards and limits at any time.
Every model, in one subscription.
Mix a fixed platform fee, metered usage, and per-transaction percentages on the same subscription — the way real SaaS, marketplaces, and platforms actually price.
- Fixed
- Flat recurring fees for plans and seats.
- Usage-based & tiered
- Per-unit, volume, and graduated tiers on metered usage.
- Hybrid
- Combine fixed, usage, and percentage components together.
Record usage with one call.
No nightly batch jobs, no reconciliation scripts. Send events and let the engine handle aggregation and invoicing.
// Record a metered usage event as it happens
await gphq.usage.record({
subscriptionItem: "si_456",
quantity: 100,
timestamp: new Date().toISOString(),
})
// Usage aggregates automatically against the price's meter
// and appears on the next invoice — no batch job required.Questions, answered.
- What aggregation types are supported?
- Sum, max, last-value, and unique-count aggregation per meter, configurable per price.
- Can I combine usage with fixed fees?
- Yes — fixed, usage-based, tiered, and hybrid components can all live on a single subscription.
- Is this an alternative to Stripe usage-based billing?
- It’s for teams who want usage billing without standardizing on one processor — bring your own gateway and self-host the engine.
Bill for exactly what customers use.
