Look, most SaaS billing systems were designed for a world that no longer exists. In traditional software, value correlated neatly with usage - more API calls = more compute = (often) more seats.
In the agentic era, that correlation breaks.
If your product is powered by AI agents, metering platforms are blind to what matters. Products like Metronome, M3ter, and Orb count activity. They don't understand outcomes. Paid collects telemetry traces (meaning what your agents do) so you can bill for value, not inputs.
If you're adding AI and agents to your SaaS, you need to read and understand this!
The Problem: Metering is not value
You may be angry with this, but Metering is a counting system. It tells you how much of something happened (typically connected to compute), not whether it mattered.
For classic SaaS models (API usage, storage, seats) counting was enough because it created a predictable relationship between cost and value.
With agents, that relationship collapses. I don't make the rules!
A single "API call" (if you can still call it that) might complete a trivial task or generate a million-dollar sales lead. A single agent run might make three dozen OpenAI requests, call an internal API, and hand off a Slack message or it might think for 30 seconds and do nothing because it ran out of context.
It's important to remind now that in the agentic world - compute ≠ value.
When you meter agents, you're measuring electricity, not intelligence.
Lots of Billing teams (myself included, at some point) thought that metering solves revenue visibility - but it doesn't.
Metering counts while telemetry understands.

Autonomous or adaptive systems
Metering platforms were built to aggregate numbers for invoicing. Telemetry platforms like Paid are built to understand what those numbers mean.

Paid's OpenTelemetry based approach captures traces: every agent decision, API call, cost, and result. It's visibility at the runtime level, not the invoice level.
What telemetry means
Telemetry isn't a buzzword we're using - but rather a standard, via OpenTelemetry. Paid collects full OpenTelemetry spans from your agent runtime:
- Every call, decision, and outcome
- Per-customer and per-order attribution: an order is a set of agents working toward one business goal
- Cross-provider visibility: OpenAI, Anthropic, Gemini, AWS Bedrock, and more
How it works
- Your code imports the Paid SDK.
- You wrap your agent run
- Paid collects spans through OpenTelemetry → aggregates traces → streams cost and value in real time.
The result is immediate runtime visibility. You see exactly what your agents did, how much they cost, and which customer or workflow generated that cost.
Why metering platforms won't keep up with agents
Metering platforms like Metronome and Orb were built for a less "adaptable" world. They can do billing for infrastructure that behaves the same way every time (like GPU usage). Agents often don't behave the same way twice, they change based on context..
Metronome
Metronome is great for classic usage billing. If your workload changes, you must update schemas and pipelines. It aggregates data before analysis, which means real-time cost view, behavioral insight, and visibility into agent execution is limited.
Orb
Orb expanded the stack adding pricing simulations and billing automation but it's still a metering-first platform. It expects a known schema and preconfigured metrics. Even with "raw events," you must decide what those events are ahead of time. That's fine for predictable usage, but impossible for adaptive agent systems.
Orb is built for billing. Paid is built for understanding.
Metronome measures aggregation. Orb measures activity. Paid measures understanding.

Paid's auto-Instrumentation: visibility in minutes
Traditional metering requires manual instrumentation — tagging every endpoint, defining usage keys, mapping data. With Paid, you wrap your existing client once.
Python
await client.trace('', async () => {
return await agent.complete_task(paid_openai)
}) Node.js
await paidClient.trace("", async () => {
return await agent.processCustomerRequest(paidOpenAiWrapper);
}, ""); That's it. No schema migrations. No per-metric code changes. Every agent execution automatically produces a full OpenTelemetry trace with cost attribution, success rates, and outcome visibility.
A few lines of code replace weeks of instrumentation.
What Telemetry Unlocks
For CTOs & CPOs
You can finally see what your AI feature is worth, which agent workflows create revenue, which waste compute, and how to price confidently.
Know which agent workflows burn most of your compute budget but generate the least customer value. Make product decisions based on actual economics, not estimates.
For Engineers
Real-time traces. No need to maintain separate logging and billing code. Debug performance issues in context: see latency, model cost, and business outcome together.
Debug with full context. See that a latency spike correlates with a model cost increase. Optimize where it matters.
For Finance
Automatic per-customer cost attribution and margin visibility. Move from billing for activity to billing for outcomes.
Stop billing customers less than it costs to serve them. Spot margin problems before they compound.
For everyone else
Telemetry makes AI monetization a closed loop: Run → Observe → Attribute → Bill → Improve.
Beyond metering: Pricing for outcomes
Metering asks: "How many API calls did you make?" Telemetry answers: "Did your agents deliver value?"
Customer A ran thousands of agent interactions last month. Half resolved tickets automatically. Half required human escalation. Should you bill the same for both?
Traditional metering says yes. Telemetry-based billing says no.
With Paid, you see:
- Customer A: High ticket resolution rates at low cost per interaction.
- Customer B: Higher cost per sales call, but thousands in potential revenue generated.
That's pricing confidence instead of guesswork. Paid's approach lets you price on intelligence, not usage.
