    They bill usage. We bill margin.

    Five tools turn events into invoices. One tells you whether the invoice was worth sending. That's the entire comparison.

    Six rows of parity. One row that matters.

    Scored from public docs and pricing pages. Amberflo is the one other vendor doing cost attribution and margin — it's packaged with an AI gateway and FinOps controls, so it's a different center of gravity, not this list. If we got something wrong, we'll fix it the same day.

    If you're choosing, here's the shortcut.

    Five vendors, one verdict each, and the case for picking them over us — written by us, on purpose.

    Open-source billing

    Lago

    vs. nozle

    Great metering core. No margin layer, no cost tracking.

    Pick them if — You must self-host for compliance.
    Enterprise monetization

    Metronome

    vs. nozle

    Best for nine-figure ARR. Four-to-six week migrations, finance-led.

    Pick them if — You're replacing Zuora with a quarter to spare.
    Pricing-ops platform

    Orb

    vs. nozle

    Cleanest pricing UX out there — but tracks revenue, not margin.

    Pick them if — Your unit economics are already healthy.
    Credit-based billing

    Flexprice

    vs. nozle

    Fast to ship credits. Doesn't ingest the inference cost behind them.

    Pick them if — You're pre-Series A, optimizing for runway.
    The default

    Stripe Billing

    vs. nozle

    Already in your stack. Subscription-first, no concept of cost or margin.

    Pick them if — You sell flat seats and never plan to meter usage.
    Otherwise

    nozle

    You want metering, pricing, billing and margin in one box — live in 60 minutes, not next quarter.

    Four lines of disagreement.

    The category settled on a default. We picked the opposite — four times in a row.

    1. Bill what you sent.

      Bill what you kept.

      Margin lives in the metering layer — or it doesn't live at all.

    2. Cost is finance's problem.

      Cost is a billing primitive.

      OpenAI, Anthropic, Bedrock, GPUs — costed at your rates and attributed per account.

    3. Quarterly migrations.

      Live in 60 minutes.

      SDK in, event out, invoice and margin land in 60 minutes.

    4. Pick a billing tool, then a finance tool.

      One stack, invoicing included.

      Invoicing, dunning, credit notes and Stripe or Razorpay collection — no second vendor.

    Three primitives. One ledger.

    Most teams stitch these from four vendors and reconcile them by hand. We treat them as one system because they always were.

    1. 01Meter

      Count what your product actually does.

      Tokens, GPU-seconds, agent runs, seats, storage — ingested at write speed and reconciled against the source of truth.

      • Streaming ingestion
      • Real-time usage counters
      • Idempotent on event ID
    2. 02Entitle

      Gate features without forking your app.

      Decide who gets what — by plan, balance, flag or commit — from a single API call. No bespoke if-statements scattered across services.

      • Real-time entitlement checks
      • Plan, seat and credit-aware
      • Mirrors the billing ledger
    3. 03Bill

      Invoice, dunning and credits in one ledger.

      Invoicing with Stripe or Razorpay collection built in. The number on your dashboard is the number on the invoice.

      • Multi-currency, multi-entity
      • Credit notes and refunds out of the box
      • Audit-ready ledger export

    Stop guessing.
    Start knowing.

    Wire Nozle into your stack and see your first margin report in 60 minutes.
