Superior Car Rental

A two-client product (Next.js web + React Native mobile) sharing a single Supabase backend, Stripe payment pipeline, and auth model. Customers browse the fleet, book a daily or hourly rental, stack loyalty points / wallet credits / promo codes at checkout, and pay via Stripe Payment Intents with webhook-reconciled confirmation. Ops receives every booking instantly through a Telegram bot.

Superior operates a premium and exotic fleet in Dubai. Reservations ran on phone calls and walk-ins, with manual coordination between dispatch, accounting, and the customer. No online channel, no payment automation, no retention mechanic for repeat customers.

1. 01

   Supabase as the single backend

   One Postgres database, one auth provider, one storage bucket for car media and customer documents. Both clients run against the same row-level-security policies.

2. 02

   Stripe Payment Intents with webhook reconciliation

   Bookings are created in a pending state and confirm only when the `payment_intent.succeeded` webhook fires. The `payment_intent.payment_failed` path releases inventory. Source of truth is Stripe's event, not the client.

3. 03

   Stackable incentives at checkout

   Loyalty points, wallet credits, and promo codes apply to the same booking. The pricing engine validates each layer, computes the max usable wallet balance against the post-discount total, and returns one auditable breakdown.

4. 04

   Daily and hourly rental in one pricing engine

   Both modes handled by the same engine, plus insurance tiers, delivery fees, extra-kilometre charges, and after-hours surcharges — all configurable per vehicle.

5. 05

   Push notifications with deep linking

   Six notification types route to specific screens in the mobile app. Ops receives every new booking on a Telegram channel.

6. 06

   SEO-led acquisition surface

   Per-brand listing pages, per-vehicle detail pages, a markdown blog, and a dynamic sitemap. Each route ships its own metadata and Open Graph image.
