# What is Paygent?

**Paygent is billing infrastructure for AI products.**

If you sell AI agents, copilots, voice assistants, or API-backed automation, you face a problem traditional billing tools weren't built for: **cost and value are driven by usage**, not seats alone. Token counts change every release. Voice calls mix LLM, STT, and telephony costs. Enterprise deals need setup fees, credit packs, and custom rates — all on one invoice.

Paygent solves this end to end: **track what your AI does, price it flexibly, and invoice automatically.**

## The problem Paygent solves

| Without usage-aware billing                             | With Paygent                                    |
| ------------------------------------------------------- | ----------------------------------------------- |
| Spreadsheets to reconcile API costs vs customer charges | Real-time usage → revenue in one system         |
| One flat subscription that loses money on heavy users   | Activity, outcome, credit, and hybrid pricing   |
| Manual invoices every month                             | Orders + automatic invoice generation           |
| No margin visibility per agent or customer              | Cost and revenue dashboards per indicator       |
| Weeks to launch a new pricing experiment                | Plans, wallets, and fee stacks in the dashboard |

## What Paygent does

1. **Tracks** — SDK records agents, indicators, tokens, voice minutes, video, and external costs
2. **Prices** — Setup fees, platform fees, seat fees, usage tiers, credits, custom model rates, taxes
3. **Packages** — Plans (Standard/Custom) and credit currencies for tiered or prepaid products
4. **Bills** — Orders define the contract; billing runs produce itemized invoices
5. **Collects** — Stripe/Razorpay payment links, manual payment recording, wallet top-ups

## Core concepts

### Agents

An **agent** is a billable AI product — a chatbot, voice assistant, code reviewer, or content generator. Each agent has an `externalId` you pass from your application.

### Indicators

An **indicator** is a billable event: `message-sent`, `call-completed`, `meeting-booked`. Activity indicators track work done; outcome indicators track results delivered.

### Plans

**Plans** package pricing into tiers (Starter / Pro / Enterprise) or custom deals per customer. Orders reference plans — not raw agent defaults.

### Orders & invoices

An **order** is the subscription contract (customer, agents, plan, billing day, taxes). **Invoices** are generated automatically from active orders — you don't create them manually.
