Architecture

Next.js App Router with edge middleware handles entitlement checks at CDN PoPs using JWT-embedded tier claims, eliminating origin round-trips for gated content. Stripe webhooks flow through an idempotent processing pipeline into Supabase with row-level security, while React Server Components conditionally render premium content server-side to prevent client-side leakage. Dunning orchestration runs as a webhook-driven state machine coordinating Stripe retries with multi-channel member communication.

Entitlement logic scattered across frontend and backend with no single source of truth Premium content leaks to free users, causing revenue loss and member trust erosion
Stripe webhook processing fails silently or handles events out of order Subscription state corruption leading to billing disputes and involuntary churn
Failed payment dunning limited to Stripe's default retry with no coordinated outreach 8-12% monthly revenue loss from recoverable failed payments
Content gating destroys page performance and blocks search engine indexing Declining organic traffic and poor Core Web Vitals tanking acquisition funnel
Edge Entitlement Engine
JWT-embedded tier claims checked in Next.js edge middleware at CDN PoPs. Sub-5ms authorization with zero origin round-trips, supporting hierarchical tier models with unlimited permission granularity.
Idempotent Webhook Pipeline
Stripe webhook events are signature-verified, deduplicated, and applied transactionally to your entitlement database. Handles out-of-order delivery and retries without state corruption.
Multi-Channel Dunning Orchestration
State machine coordinating Stripe Smart Retries with timed email sequences, in-app banners, grace periods, and automatic downgrades. Recovers 20-30% of failed payments automatically.
SEO-Preserving Content Gating
React Server Components render premium content server-side for authorized users while serving fully indexable public teasers to search engines and free members.
Real-Time Plan Switching
Upgrades, downgrades, and add-ons propagate globally in under 2 seconds via webhook-driven session invalidation. Stripe handles proration; our engine handles entitlements.
Tier-Aware CMS Publishing
Content authors tag articles, courses, and resources with required tier levels in Sanity or Payload CMS. The gating engine enforces access automatically without developer intervention.
How do you handle tiered access control without degrading page performance?

Entitlement checks run in Next.js edge middleware at CDN points of presence — no origin round-trips. Session tokens carry embedded tier claims that decode in under 5ms at the edge. Premium content renders server-side via React Server Components while public teasers stay cached and fully indexable. The result? Lighthouse 95+ scores even on heavily gated pages.

What dunning recovery rates do you typically achieve?

Our dunning system combines Stripe Smart Retries with multi-channel email sequences, in-app banners, grace periods, and automatic downgrades — and it consistently recovers 20-30% of failed payments. That's roughly double what Stripe's built-in recovery achieves on its own. Every touchpoint is webhook-driven and idempotent, so duplicate messages don't fire even under high event volume.

Can the platform support multiple pricing models simultaneously?

Yes. We model Stripe Products and Prices to support monthly/annual toggles, per-seat team pricing, usage-based metering, one-time add-ons, and hybrid combinations — all within the same subscription. Promotional coupons, free trials, and grandfathered pricing run natively through Stripe's subscription scheduling API, with our entitlement engine reflecting changes in real time.

How do you prevent premium content from leaking to unauthorized users?

Premium content never reaches the client for unauthorized users. React Server Components render gated blocks server-side based on authenticated tier, and edge middleware blocks unauthorized route access before the request ever hits origin. Row-level security in Supabase enforces data isolation at the database layer. We audit for content leakage during QA with automated tier-switching tests across every gated route.

What happens when a member upgrades or downgrades mid-billing cycle?

Stripe handles proration automatically. Our webhook pipeline processes the `customer.subscription.updated` event, updates the entitlement record in Supabase transactionally, and invalidates the user's session token. On their next request, edge middleware issues a fresh token with the new tier claim. Access changes propagate globally in under 2 seconds — no manual intervention required.

How long does a typical membership platform project take to launch?

Most projects run 10-16 weeks from kickoff to production. Weeks 1-2 cover architecture and Stripe modeling. Weeks 3-10 build the core platform — auth, billing, webhooks, gating, dunning. Weeks 11-16 handle optimization, security audits, load testing, and staged rollout. We offer post-launch retainers for ongoing dunning optimization, new tier rollouts, and Stripe API version management.

Does gated content hurt SEO since search engines can't see premium pages?

We architect gated pages with public teaser content that's fully indexable — article intros, course descriptions, structured data — while premium content renders only for authenticated users via server components. Google indexes the public shell, driving organic traffic to upgrade prompts. Search visibility stays strong. Premium content stays protected.
