Monetizing your application is often the next logical step after building something users love.

Subscription plans are a common strategy to build sustainable revenue into your SaaS, enabling premium features for individual users or teams with active plans. However, implementing subscriptions from scratch can be time-consuming and error-prone due to the complexity of the underlying infrastructure and logic.

That's why we built Billing.

Just as Clerk streamlines authentication and user management, it now does the same for subscriptions. You get a polished UI that allows your users to easily select and manage their preferred plan, as well as helper functions to easily gate access to premium features, all without writing custom billing logic from scratch.

In this article, you'll learn what Clerk Billing is, how it works, and how to implement it in a real-world application.

What Is Clerk Billing?

Clerk Billing is our latest offering that brings subscription management directly into your existing authentication stack. With just a few clicks in the Dashboard, you can define subscription plans and their associated features, which are displayed in your application with the drop-in <PricingTable /> component.

Clerk integrates directly with your Stripe account, letting Stripe handle the actual payment processing while Clerk handles the user interface and entitlement logic. During development, you can even work in a sandbox environment without requiring a Stripe account. This mirrors the way Clerk handles SSO, where development instances use shared credentials until you're ready to go live.

How Billing Works

You'll start in the Clerk dashboard, where you define your plans and add features to them.

Features are essentially flags that indicate what a user has access to. For example, if your “Pro” plan includes advanced analytics, you'd create an “Analytics” feature and assign it to the plan. Features can be shared across multiple plans, allowing you to build a pricing structure thats increases access to your application as the selected plan increases.

You can configure your plans to be billed monthly or offer discounts for annual subscribers. Once your plans are created, you're ready to display them in your app.

The <PricingTable /> component

The core UI component used with Billing is the <PricingTable />. It's a single-line component that renders a fully functional plan selector and payment form inside your app.

When a user selects a plan, a modal drawer will open to collect their payment details. It's a smooth and familiar experience for users and requires no custom form building on your part.

Users can also subscribe to new plans and manage existing subscriptions directly through the <UserProfile /> component. The new Billing tab also includes invoice history and linked payment sources. This centralizes authentication, profile management, and billing into one cohesive experience.

Verifying the User's access

One of the most powerful features in Clerk is the has() helper. Originally built to power B2B access controls, it checks whether a user has a specific role or permission. With Billing, it now supports checking a user's plan or feature (entitlement) access.

This makes it incredibly easy to gate access to premium content or features with a single, readable function call.

Managing Subscriptions

Once users are subscribed, you can manage their subscriptions directly from the Clerk dashboard. There's a new Subscriptions tab where you can search for users, view their subscription status, and even cancel plans if needed.

Cancelled plans won't immediately remove access, they'll simply stop renewing, giving your users access until the current billing cycle ends. You can also view a user's plan details at a glance, which is especially useful for support and admin workflows.

Implementing Billing in Quillmate

To demonstrate how easy it is to implement Billing into an application, I'm going to add subscriptions to Quillmate, a web-based writing platform built with Next.js, Clerk, and Supabase. The Pro plan for Quillmate offers an AI assistant that users can access while writing new articles. If the user is not a subscriber, they will be prompted to subscribe when they attempt to access the chat assistant.

Creating the plans

I'll start in the Clerk dashboard and navigate to Configure > Subscription Plans, then click Add User Plan.

In the next screen I'll name the plan (which will auto-populate the slug), add a description, and set the monthly price.

Before saving I'll scroll down a bit to create the feature that's associated with the plan by click Add Feature. I'll name the feature “AI Assistant” and provide a description before saving. Take note of the slug as it will be used in the code to check if the user can access this feature.

Add the pricing table

Now that my plan and feature are created, I can start updating the code. The first thing I'm going to do is create a new page that shows the available subscriptions. This will be a page that users can access at /subscribe. The page itself contains some promo text, but the main thing to note is the <PricingTable /> component which is all I need to render the available plans and features:

This page shows a list of available plans and features for Quillmate users:

Selecting Get Started under the plan will simply open a drawer where I can enter my payment information to be processed by Stripe!

Protecting the AI Chat feature

For each article, Quillmate has a floating action button in the lower right that users can click to access the assistant. This feature should only be available to users who subscribe to the Pro plan, or more specifically, a plan with the “AI Assistant” feature.

Users can also manage their plan directly from the <UserButton /> component in the new Billing tab:

Conclusion

Clerk Billing takes all the usual friction out of implementing subscriptions—no need to wire up your own Stripe forms, manage customer data, or create custom logic for checking user plans. It's fully integrated into your authentication layer, shares the same DX principles as the rest of Clerk, and gets you from “idea” to “monetized” in record time.

Whether you're just validating a pricing model or launching a full-featured SaaS product, Clerk Billing is built to get you there faster, with fewer moving parts.
