Every event metered.
Every cent accounted for.
UsageB sits between your product and your revenue stack — metering raw usage, rating it against any pricing model, and producing bills your finance team can sign without a spreadsheet open.
- events metered every day
- 12.4B
- ingestion uptime, trailing year
- 99.99%
- rounding drift tolerated
- $0.00
- from event to rated revenue
- < 60s
A single source of truth for usage
Send raw events from your product with one API call. UsageB deduplicates, validates, and aggregates them in real time — so finance, product, and engineering all read from the same ledger, down to the individual event.
- —Idempotent ingestion at any scale
- —Streaming aggregation in seconds
- —Complete, replayable audit history

}Price the way you sell, not the way your tools allow
Tiers, volume bands, prepaid credits, committed spend, per-seat hybrids, custom enterprise terms — model them all declaratively, version every change, and trial new pricing against historical usage before a single customer sees it.

Bills that are already correct on the last day of the month
UsageB rates usage continuously, not in a month-end batch. Every account's bill is computed and re-computed all period long — credits drawn down, commitments tracked, proration handled — then handed off to your invoicing and ERP systems.
- —Continuous, in-period bill calculation
- —Credits, commitments, and proration built in
- —Cent-level accuracy you can audit

Plugged into the systems your revenue runs on
Sync rated usage and bills to Stripe for payment, Salesforce for the field, NetSuite for the books, and your warehouse for analysis. Build automations on webhooks and a full API so billing ops stops being manual ops.
- —Native CRM, ERP, and payments sync
- —Cloud marketplace billing included
- —Webhooks and APIs for everything
From raw event to closed books, in one pipeline
One endpoint between your product and getting paid
Fire an event when usage happens. That's the whole integration. Idempotency keys make retries safe, batching is automatic, and everything downstream — aggregation, rating, invoicing — is configuration, not code.
// meter usage the moment it happens
import { UsageB } from "@usageb/node";
const usageb = new UsageB(process.env.USAGEB_KEY);
await usageb.measurements.create({
meter: "api.requests",
account: "acct_meridian",
value: 1,
uniqueId: requestId, // retries are free
});“We re-priced our entire API tier mid-quarter and closed the month two days early. Before UsageB, either of those sentences would have been a joke.”
