Your agent loses users every time it
says "go to our pricing page"

Standard billing tools weren't built for conversational AI. Here's what that costs you.

User drop-off at billing redirects

Users leave when the agent sends them to an external checkout page or billing portal. They rarely come back.

Building billing logic is a time sink

Developers spend weeks wiring up Stripe webhooks, usage tracking, and billing state into their agent's conversation flow. It's fragile and breaks often.

Failed payments go unrecovered

When a card fails or a subscription lapses, the typical recovery is a dunning email. There's no way to handle it inside the conversation where the user already is.

Gating is crude and frustrating

Most agents either hard-block users with a generic error or have no gating at all. There's no graceful middle ground — no upsell, no context, no alternatives.

Billing logic doesn't understand context

Traditional billing operates on API calls and webhooks, completely disconnected from what the user is actually doing. The agent has no awareness of billing state.

Three steps to billing-aware agents

1

Install the SDK

$ npm install paygent

Or with pip: pip install paygent

2

Configure monetization rules

Define usage limits, pricing tiers, upsell triggers, and soft/hard gates — all in your agent configuration. Works with LangChain, CrewAI, AutoGen, LangGraph, or any custom setup.

The agent handles the rest

Upsells, upgrades, payment recovery, and graceful gating — all in natural conversation. Paygent gives your agent the tools and awareness to handle money moments without breaking flow.

Can you analyze this dataset too?

I'd love to — that would use your remaining 2 credits. Want me to upgrade you to Pro for unlimited analysis? I can do it right here, takes 10 seconds.

Sure, go ahead.

Done! You're on Pro now. Let me start that analysis...

The agent handles the upgrade — right in the conversation.

Everything your agent needs to handle money

Conversational upsells

The agent suggests upgrades at exactly the right moment, in context, without feeling pushy or breaking the flow.

Graceful limit enforcement

Soft gates (gentle warnings) and hard gates (firm stops) — fully configurable so the agent responds exactly as you want.

Payment recovery

Agent handles failed payments in-chat instead of firing off dunning emails that get ignored.

Billing-aware agents

The agent knows the user's plan, usage, and limits in real time. It makes smart decisions rather than guessing.

Framework agnostic

Works with LangChain, CrewAI, AutoGen, LangGraph, or any custom agent setup. No lock-in.

Billing backend agnostic

Sits on top of Stripe, Paddle, or any billing system. It's the last mile between your backend and the conversation.

Developer-first

Clean SDK, webhook support, detailed docs. Most teams are fully set up in under 5 minutes.

Built for builders dealing with this right now

"I'm building an AI agent and users drop off at the paywall"

"I've hacked together Stripe webhooks to handle billing in my agent, and it's fragile"

"I want my agent to upsell users without feeling pushy"

"My agent has no idea what plan the user is on — it can't make smart gating decisions"
