Summary

  • Adds NEXT_PUBLIC_BILLING_ENABLED feature flag to toggle between Stripe checkout and a waitlist flow
  • When billing is disabled (production): upgrade buttons become "Join Waitlist", submitting sends an admin notification email with user/org/plan details, and buttons change to "You're on the list!"
  • When billing is enabled (UAT/preview): existing Stripe checkout flow works unchanged

Changes

  • env.ts — new NEXT_PUBLIC_BILLING_ENABLED client env var
  • billing.ts — new joinWaitlist server action
  • email.ts — new sendWaitlistNotificationEmail function
  • waitlist-notification.tsx — admin email template (follows signup-notification.tsx pattern)
  • billing-page-client.tsx — branches on flag, extracted handleCheckout/handleWaitlist helpers
  • plan-card.tsx — new waitlistMode/onWaitlist props for button state

Test plan

  • 15 new unit tests (PlanCard waitlist props + BillingPageClient flow branching)
  • Set NEXT_PUBLIC_BILLING_ENABLED=false in Vercel production
  • Set NEXT_PUBLIC_BILLING_ENABLED=true in Vercel preview
  • Verify waitlist email arrives with correct details
  • Verify Stripe checkout still works in preview

replace upgrade buttons with "join waitlist" flow when
NEXT_PUBLIC_BILLING_ENABLED is unset or false. sends admin
notification email with user/org/plan details. stripe checkout
remains active when flag is set to true for uat/preview testing.
