I’m building a full-stack web platform that sells access to an in-house large-language-model (LLM). The site’s core is e-commerce, but instead of one-off product sales I need subscription services with clear, tiered plans (think “Starter”, “Pro”, “Enterprise”). Each tier will unlock a different usage quota to the model, so the paywall must integrate tightly with the API gateway that fronts the LLM. Scope of work • Design a responsive customer-facing site where visitors can learn about the model, compare tiers, and sign up. • Implement secure user authentication, payment processing, and a dashboard where subscribers can view remaining tokens, upgrade/downgrade, or cancel. • Build the back-end that meters requests to the LLM by tier and logs usage for transparent billing. • Provide an admin console for me to create new tiers, adjust pricing, and view analytics. • Deploy the stack (preferred toolset: React or [login to view URL] on the front end, Node/Express or Python/FastAPI on the back end, Stripe for payments, and a relational DB) to a cloud host of your choice. Acceptance criteria 1. A new user can register, choose a tier, pay, and immediately receive an API key scoped to that tier. 2. Usage throttling kicks in when limits are reached and resets automatically on renewal. 3. Tier changes prorate correctly. 4. Admin actions update live without downtime. 5. Codebase is delivered in a Git repo with a README covering local setup, env vars, and deployment commands. If you have previous experience building subscription SaaS or AI tool marketplaces, that will help us move fast. Let me know your preferred stack, estimated timeline, and any clarifying questions.

Your LLM subscription model is the tricky part: tying tiered plans to live API usage quotas while keeping checkout frictionless. Here's the architecture I'd build: ⢠Stripe Checkout + Customer Portal for tiered subscriptions (Starter/Pro/Enterprise) with automatic recurring billing ⢠Middleware that validates JWT tokens against subscription tiers and enforces request/usage quotas per billing cycle ⢠Usage-metering pipeline that increments counters per API call and triggers webhook events at 80% and 100% thresholds ⢠Customer dashboard showing current usage, plan limits, and one-click upgrade/downgrade paths ⢠Clean admin panel to adjust tier quotas, pricing, and view subscriber analytics We run a SaaS platform with similar subscription-to-usage gating â the metering layer is where most builds fail, and ours is already production-tested.

Stripe checkout is the easy half. What eats time on these builds is keeping the LLM API layer in sync with subscription state. A subscriber who cancels mid-cycle, has a card decline, or pauses needs access revoked immediately, not on their next login attempt. The reliable way to handle that: Stripe webhooks write to a subscription status table, and your LLM API middleware reads from that table on every request. No polling, no stale session data. Failed payment triggers a grace window; cancellation triggers immediate lockout. That logic needs to be correct from the start; retrofitting it after launch is genuinely messy. What I'd deliver: Stripe-integrated checkout with recurring billing, webhook handler for all subscription lifecycle events (created, updated, cancelled, payment_failed), auth layer (JWT or session-based), and a gated API proxy for your LLM with live entitlement checks on every request. Frontend to go with it: account dashboard, subscription management, billing history. $640, 14 days. One question before I lock in the approach: are you hosting the LLM on your own infra or proxying a third-party provider? That changes how the API gateway layer is built.
