Case study
An internal billing and practice-operations dashboard for Greater Change Health's therapy business - Stripe subscriptions, tiered pricing, and a full audit trail, later split onto Cloudflare's edge network.
Delivered with our partnerHenge 
Project overview
Greater Change Health needed more than a payment link: recurring therapy subscriptions, discounted first sessions, promo codes, add-ons, and a clear record of who changed what. We built GCH Billing as a dedicated internal tool so the operations team can manage pricing, subscriptions, and Stripe reconciliation without touching code.
The challenge
Session-based therapy billing has real edge cases: discounted first sessions, couples billing, card-verification holds, and retries on failed payments. Handling this by hand in the Stripe dashboard was slow and left no clear record of who adjusted a client's plan, or why.
What we did
We built a Fastify API and Next.js dashboard around Stripe: hosted Checkout with optional Klarna, a self-serve Customer Portal for clients, tiered pricing with add-ons, promo codes with a saved snapshot per client, role-based access, and an audit log covering every sensitive action. Chart widgets for revenue, churn, and top customers are drag-and-drop, so the team builds the dashboard views it actually uses.
Under the hood
Hosted Checkout with optional Klarna, a self-serve Customer Portal, and an admin job that reconciles the database against Stripe.
Discounted first sessions, standard-rate renewals, and one-time add-ons are managed from tables, not hardcoded logic.
Every sensitive action is logged and filterable by admin, action, entity, and date, across 14 incremental schema migrations.
A drag-and-resize chart grid with revenue, churn, and per-tier breakdowns, saved per admin.
The Results
The original Docker-Compose app (Fastify API, Next.js dashboard, Postgres, Nginx) was later re-architected for Cloudflare: the dashboard shipped as a Worker, while the Fastify API, which needs native bcrypt, a persistent Stripe scheduler, and a Postgres connection pool, moved into a Cloudflare Container instead of being force-fit into a stateless Worker. Every migration and the full Stripe integration carried over unchanged.
