Billing
STOP, prerequisite. Billing must be enabled before any
<PricingTable />,<CheckoutButton />,has({ plan }), orhas({ feature })usage works. Two paths: (1) Dashboard → Billing → Settings, or (2)clerk enable billing(see "Agent-first: Programmatic billing config" below). Enabling auto-creates defaultfree_user/free_orgplans. Dev instances can use the shared Clerk development gateway (no Stripe account needed); production requires a Stripe account for payment processing only.Note: Billing APIs are still experimental. Pin your
@clerk/nextjsandclerk-jspackage versions. Seeclerkskill for the supported version table.
Quick Start
-
Enable Billing, via Dashboard → Billing → Settings or
clerk enable billing(see Agent-first section). Skipping this throwscannot_render_billing_disabledin dev and renders empty in prod. -
Create plans in the matching tab, Dashboard → Billing → Plans. Two tabs, slugs scoped per tab, not movable after creation:
- User Plans →
<PricingTable />(defaultfor="user") - Organization Plans →
<PricingTable for="organization" />
Wrong-tab is the #1 cause of an empty
<PricingTable />. Plans live in Clerk; not synced to Stripe. - User Plans →
-
Add features inside a plan, open the plan in Dashboard → Billing → Plans, use its Features section. Features are scoped per plan, not global. The same slug can attach to multiple plans;
has({ feature: 'export' })matches if the active plan contains that slug. -
Render
<PricingTable />(passfor="organization"for B2B). -
Gate access with
has({ plan })orhas({ feature })fromauth(). -
Handle billing webhooks for subscription lifecycle.

Agent-first: Programmatic billing config
The full billing config (enable toggles, plans, features, plan-feature attachments) is editable via PLAPI without touching the Dashboard. Useful for agents seeding plans, replicating config across instances, or version-controlling billing structure.
Pre-req: project linked to the Clerk app (clerk auth login + clerk link, see clerk-setup).
Enable Billing via CLI
clerk enable billing # both targets (default, auto-creates free_user + free_org plans)
clerk enable billing --for org # org only
clerk enable billing --for user # user only
Pull current billing config
clerk config pull --keys billing > billing.json
This writes the current billing config (toggles + plans + features) for the linked instance to billing.json.
Edit and apply
Edit billing.json to add/remove plans or features, then preview the diff and apply:
clerk config patch --file billing.json --dry-run
clerk config patch --file billing.json
Pass --instance prod to target the production instance instead of dev.
Raw PATCH (full control)
For one-shot plan/feature updates without a config file:
clerk api --platform PATCH /v1/platform/applications/<app_id>/instances/<ins_id>/config \
-d '{"billing":{"plans":[{"slug":"pro","name":"Pro","amount":2000,"currency":"usd","payer_type":"user","is_recurring":true}],"features":[{"slug":"export","name":"Export"}]}}'
Notes
- This handles billing config (toggles + plans + features catalog). Subscription lifecycle (users picking a plan, checkout, renewal, cancellation) still flows through
<PricingTable />+ billing webhooks, seeclerk-webhooksskill for the lifecycle events. - Top-level
featuresmap manipulation and plan-feature attachments (sync) are fully supported via the PLAPI billing config handler.

Features vs Plans: When to Use Which
Use has({ feature: 'slug' }) when gating a specific capability, export, analytics, API access, audit logs.
Use has({ plan: 'slug' }) when gating a tier, showing the pro dashboard, checking org subscription level, redirecting free users.
| Scenario | Correct check |
|---|---|
| Gate the "Export CSV" button | has({ feature: 'export' }) |
| Gate the "Analytics" section | has({ feature: 'analytics' }) |
| Gate all of /dashboard/pro | has({ plan: 'pro' }) |
| Check if org has team subscription | has({ plan: 'org:team' }) |
| Gate SSO configuration | has({ feature: 'sso' }) |
When a user says "gate the export feature" or "gate analytics", always use has({ feature }). Only use has({ plan }) when the gate is the plan tier itself, not a specific capability within it.
Key Patterns
1. Render the Pricing Table
Show available plans to users with a single component:
import { PricingTable } from '@clerk/nextjs'
export default function PricingPage() {
return (
<main>
<h1>Choose a plan</h1>
<PricingTable />
</main>
)
}
<PricingTable /> automatically renders all plans configured in the Clerk Dashboard. Selecting a plan opens Clerk's in-app checkout drawer. No props needed for basic usage. For B2B, pass for="organization" to render org-level plans instead of user plans.
2. Check Feature Entitlements (Server-Side)
Gate by individual features, this is the preferred approach for specific capabilities:
import { auth } from '@clerk/nextjs/server'
export default async function AnalyticsPage() {
const { has } = await auth()
const canViewAnalytics = has({ feature: 'analytics' })
const canExport = has({ feature: 'export' })
return (
<div>
{canViewAnalytics && <AnalyticsChart />}
{canExport && <ExportButton />}
</div>
)
}
Features are configured in Clerk Dashboard → Billing → Features and assigned to plans. Use has({ feature }) instead of has({ plan }) when gating granular capabilities, check the feature, not the plan.
3. Check Feature Entitlements (Client-Side)
Use useAuth() for client-side feature gating. Combine with server-side checks for full coverage:
'use client'
import { useAuth } from '@clerk/nextjs'
export function FeatureGatedUI() {
const { has, isLoaded } = useAuth()
if (!isLoaded) return null
const canExport = has?.({ feature: 'export' })
const canAnalytics = has?.({ feature: 'analytics' })
return (
<div>
{canAnalytics && <AnalyticsSection />}
{canExport ? <ExportButton /> : <UpgradeToExport />}
</div>
)
}
Server Components use auth(), Client Components use useAuth(). Both support has({ feature }) and has({ plan }).
4. Check Subscription Plan Server-Side
Gate access by subscription plan (use this for tier-level gates, not individual features):
import { auth } from '@clerk/nextjs/server'
import { redirect } from 'next/navigation'
export default async function ProDashboard() {
const { has } = await auth()
if (!has({ plan: 'pro' })) {
redirect('/pricing')
}
return <ProFeatures />
}
5. Client-Side Plan Checks
Use useAuth() hook for client components:
'use client'
import { useAuth } from '@clerk/nextjs'
export function UpgradePrompt() {
const { has } = useAuth()
if (has?.({ plan: 'pro' })) {
return null
}
return (
<div>
<p>Upgrade to Pro to access this feature</p>
<a href="/pricing">View plans</a>
</div>
)
}
6. B2B Seat-Based Billing with Organizations
Org plans can carry a seat limit (membership cap) that Clerk enforces at invite time. Use the org: slug prefix on org-side plan checks (e.g. has({ plan: 'org:team' })) to keep gating unambiguous. Render the B2B pricing page with <PricingTable for="organization" />, and use <OrganizationProfile /> for the org account billing UI.
See references/b2b-patterns.md for tiered plan naming, seat-limit invariants, admin-only billing, and webhook handlers.
7. Display Subscription Status
Check specific plans with has({ plan }), or use useSubscription() for full subscription details in client components. Do not read plan information from sessionClaims directly, that is not the supported path.
Server component, check for specific plans:
import { auth } from '@clerk/nextjs/server'
export default async function AccountPage() {
const { has } = await auth()
const currentPlan = has({ plan: 'pro' })
? 'pro'
: has({ plan: 'starter' })
? 'starter'
: 'free'
return (
<div>
<h2>Current Plan</h2>
<p>You are on the {currentPlan} plan</p>
{currentPlan === 'free' && <a href="/pricing">Upgrade</a>}
</div>
)
}
Client component, full subscription details via useSubscription():
'use client'
import { useSubscription } from '@clerk/nextjs/experimental'
export function SubscriptionDetails() {
const { data: subscription, isLoading } = useSubscription()
if (isLoading) return null
if (!subscription) return <a href="/pricing">Choose a plan</a>
return (
<div>
<p>Status: {subscription.status}</p>
{subscription.nextPayment && (
<p>Next payment: {subscription.nextPayment.date.toLocaleDateString()}</p>
)}
</div>
)
}
useSubscription()is for display only. For authorization checks (gating content or routes), always usehas({ plan })orhas({ feature }).
8. Protect API Routes by Plan
Gate API routes using auth():
import { auth } from '@clerk/nextjs/server'
import { NextResponse } from 'next/server'
export async function GET() {
const { has } = await auth()
if (!has({ plan: 'pro' })) {
return NextResponse.json({ error: 'Pro plan required' }, { status: 403 })
}
return NextResponse.json({ data: 'premium data' })
}
9. Handle Billing Webhooks
Clerk event names differ from Stripe event names. Clerk billing webhooks use dot-notation and camelCase, not Stripe's underscore format.
There is no
subscription.canceledevent. Cancellation fires at the item level assubscriptionItem.canceled.
Intent Stripe event name Clerk event name Subscription created customer.subscription.createdsubscription.createdSubscription updated customer.subscription.updatedsubscription.updatedSubscription active (none) subscription.activeSubscription past due (none) subscription.pastDueSubscription item canceled customer.subscription.deletedsubscriptionItem.canceledSubscription item past due invoice.payment_failedsubscriptionItem.pastDueSubscription item updated (none) subscriptionItem.updatedSubscription item active (none) subscriptionItem.activeSubscription item upcoming renewal (none) subscriptionItem.upcomingSubscription item ended (none) subscriptionItem.endedSubscription item abandoned (none) subscriptionItem.abandonedSubscription item expired (none) subscriptionItem.expiredSubscription item incomplete (none) subscriptionItem.incompleteFree trial ending soon (none) subscriptionItem.freeTrialEndingPayment attempt created (none) paymentAttempt.createdPayment attempt updated (none) paymentAttempt.updatedAlways use Clerk's event names, never Stripe's, in
evt.typechecks.
Payload shape. Clerk billing webhook payloads are nested. The subscribing entity lives under
evt.data.payer(fields:user_id?,organization_id?). The plan info is on each item underevt.data.items[i].plan.slug. The subscription id is simplyevt.data.id. Subscription items do not carry asubscription_idfield back-reference, so insubscriptionItem.*handlers you identify the record by the item id (evt.data.id) or look up by payer plus plan.
Minimal handler to anchor the pattern (import from @clerk/nextjs/webhooks, verify, branch on Clerk event name):
import { verifyWebhook } from '@clerk/nextjs/webhooks'
import { NextRequest } from 'next/server'
import { db } from '@/lib/db'
export async function POST(req: NextRequest) {
let evt
try {
evt = await verifyWebhook(req)
} catch {
return new Response('Verification failed', { status: 400 })
}
if (evt.type === 'subscription.created') {
const { id, payer, items, status } = evt.data
const entityId = payer.organization_id ?? payer.user_id
const plan = items[0]?.plan?.slug
await db.subscriptions.upsert({
where: { subscriptionId: id },
create: { subscriptionId: id, entityId, plan, status },
update: { entityId, plan, status },
})
}
// Add more branches per the event catalog above (subscription.updated,
// subscriptionItem.canceled, subscriptionItem.pastDue, etc.)
return new Response('OK', { status: 200 })
}
For the full template covering all 15 events, the TS type declarations from @clerk/backend, the proxy.ts public-route setup, and the subscription status value table, see references/billing-webhooks.md.
10. Upgrade / Downgrade Flow
Let users manage their subscription from inside the app:
import { PricingTable } from '@clerk/nextjs'
import { auth } from '@clerk/nextjs/server'
export default async function BillingPage() {
const { has } = await auth()
const isPro = has({ plan: 'pro' })
return (
<div>
<h1>Billing</h1>
{isPro ? (
<div>
