E-commerce & Booking Platforms

Headless commerce storefronts and booking systems with real payment integration — Stripe for international, PhonePe for India — built to handle actual transactions, not a checkout demo.

What this covers

Commerce and booking flows are unforgiving — a broken edge case means a lost sale or a double-booked slot. This service is end-to-end: catalog/booking logic, payment integration, webhooks, and the admin tooling to manage it all.

  • Headless commerce: storefronts built on top of Shopify's Storefront API or a custom catalog, decoupled from a rigid theme system.
  • Booking systems: slot/group booking logic, availability rules, and confirmation flows.
  • Payments: Stripe integration with webhooks for international payments, PhonePe for the Indian market.
  • Admin & CRM tooling: role-based back-office systems to manage orders, bookings, and customers.

How it typically goes

Map the transaction flow

Every payment/booking edge case — failed payments, partial refunds, double-booking — gets planned before code starts.

Integrate payments properly

Webhooks, idempotency, and reconciliation — not just a "success" redirect that hopes for the best.

Ship with admin tooling

You get a way to see and manage what's happening, not just a storefront with no back office.
