Analytics. Visibility. Control.

Customer Entitlement Management & Analytics
for Your Whole Team

Runtime enforcement of plans and limits, with usage analytics.

Sales, support, finance, and engineering each get the view of customer usage and ownership that matters to them, all from one source of truth.

Customer Entitlement & Usage Record
Sales

See what a customer already owns — spot renewal and upsell openings before the call

Support

See entitlements instantly, resolve access issues without a ticket to engineering

Finance

See usage and revenue exposure in real time, not at month-end close

Engineering

Ship once — entitlement logic lives outside the codebase, not hard-coded in it

Usage-Based Billing, in Practice

How Zenmeter Actually Works

Every plan a customer buys can be a hybrid — a subscription tier for features that are simply on or off, plus usage limits Zenmeter controls at runtime. What happens when a customer buys, uses, and pays for that plan follows one of three flows.

Choose a Flow
Purchase + Add-Ons

Purchase + Add-On Allowances When Required

Customers buy a plan — from your e-commerce checkout, or a paid invoice from your billing system. Zenmeter provisions the entitlement with a fixed usage cap on the features that need one, and enforces it by blocking further use once the customer hits it.

Entitlement provisioned with a fixed cap

Zenmeter blocks usage at the cap

Add-on purchase re-provisions the entitlement

No automatic billing event when the cap is hit — just a stop, until the customer makes a new purchase (an add-on pack) that re-provisions the entitlement.

What Zenmeter Also Handles

Credits, Rollovers & Limits

Usage credit rollovers, token usage tracking for AI-powered features, and soft or hard usage limits tuned to each customer segment.

CRM Integration

Zenmeter integrates with your CRM, so usage and entitlement data are visible to sales and support where they already work.

E-Commerce & Billing Integration

Zenmeter integrates with your e-commerce and enterprise billing systems, fitting into your purchase, fulfillment, and quote-to-cash workflows.

The software companies winning right now are the ones who can test, launch, and iterate on pricing as fast as the market moves. That requires infrastructure most teams don't have.

AI Monetization

Monetize the new AI Functionality & Features
in Your Product.

Zenmeter meters customer usage and enforces their entitlements and subscriptions — capturing, rating, and triggering billing.

AI Agent usage events and token burn, API calls, credits, are accurately tracked, so high-frequency AI usage can be monetized easily for products that include AI functionality.

Implementing new pricing — tokens, credits, overages, hybrid plans — that even works for complex multi-user B2B customer accounts simply becomes configuration rather than lengthy, expensive engineering efforts to rewrite product code.

See how this powers AI monetization — from per-token metering to margin-safe pricing plans for every customer.

Frequently Asked

Questions about Zenmeter.

All are modern metering platforms. Zenmeter covers hybrid licensing where 'seats + usage' is required, suited to SaaS sold B2C and B2B, covering rate card complexity with ease for AI functionality token consumption. Also it ships as part of the Nalpeiron Growth Platform — metering, runtime entitlement enforcement, and revenue intelligence in one connected system designed to increase revenues.

Yes. Zenmeter is the metering and entitlement layer, not a billing system. It integrates with your billing system of choice to deliver much more capable and flexible Usage-Based Billing. It powers hybrid plans which include subscriptions with usage-based dimensions. Rated usage and entitlement state flow downstream so invoices and revenue recognition reflect what has actually been consumed.

Yes. Zenmeter checks entitlements at runtime via API with millisecond latency, so customers can't exceed paid limits even at high event volumes. Caps, credits, and overage rules are evaluated inline — the application asks 'is this customer allowed to do X?' and gets back an authoritative answer before the action completes. Both soft warnings (notify before cutoff) and hard caps (block at cutoff) are supported.

Pay-as-you-go (rate per event), prepaid credits (deplete a bucket), hybrid-flex (seats plus usage plus features), tiered consumption (rate changes by volume), and credit-based packaging (AI token packs, API call packs, data bundles). You can combine any of these in a single plan — for example, a per-seat base price plus prepaid AI credits plus pay-as-you-go overages on API calls.

Both. Zenmeter was built to handle AI-grade event volumes (tokens, inferences, embeddings), but the same architecture meters API calls, data ingestion, compute hours, feature usage, seat consumption, and any other countable event. If your product generates a usage event, Zenmeter can capture, rate, and enforce against it.

Yes. Zenmeter is built for sustained high-throughput ingestion with millisecond rating — designed for AI infrastructure and SaaS products that emit billions of events per month. Hard caps and overage logic are evaluated inline so high event rates don't bypass entitlement checks.

Key Terms

What Zenmeter is, in plain terms.

What is a metering platform?

A metering platform captures, rates, and reports usage events from a software product — API calls, AI tokens, data ingested, compute hours, seats consumed — and turns them into billable line items in real time. It sits between your application and your billing system, enforcing entitlements at runtime so customers can't exceed paid limits and revenue isn't lost to unattributed usage. Zenmeter is Nalpeiron's metering platform, built for millisecond rating at any scale.

What is a SaaS entitlement engine?

A SaaS entitlement engine decouples what a customer is allowed to do from your application code. Instead of hard-coding feature checks and seat counts, the entitlement engine stores plans, features, and limits as data and serves real-time checks via API or SDK. When a customer upgrades, downgrades, or hits a usage cap, the engine reflects the change immediately — no release required. Zenmeter handles entitlement enforcement for modern cloud-native SaaS.

What is consumption-based entitlement?

Consumption-based entitlement is a model where customer access is governed by usage, not static feature toggles or seat counts. Limits, credits, and overage rules are enforced in real time as events stream in. It is how modern SaaS — especially AI products — sells: pay-as-you-go, hybrid plans (seats plus usage), and credit-based packaging are all consumption-based entitlement models. Zenmeter powers this across every pricing model and event type.
