Custom Storefront
Why Headless?
Traditional Shopify themes impose hard limits on performance, design, and functionality. Going headless decouples your storefront from the commerce engine — giving you full creative and technical control while keeping Shopify Plus as the reliable backbone for orders, inventory, and checkout.
Performance
Next.js renders pages at the edge with ISR and streaming SSR. Sub-second loads, perfect Core Web Vitals, and a shopping experience that converts.
Flexibility
No theme constraints. Pixel-perfect UI, custom animations, unique product experiences — built exactly to your brand spec with zero compromise.
Scale
Shopify Plus SLAs handle peak traffic. Vercel’s global edge network ensures fast delivery worldwide. Built to grow with your revenue.
The Tech Stack
Shopify Plus
Enterprise-grade commerce platform. Handles products, inventory, orders, discounts, B2B, and checkout. Accessed via Storefront API (GraphQL).
Next.js 15 (App Router)
React framework with server components, streaming SSR, ISR, and edge middleware. Deployed on Vercel for global CDN distribution.
Headless CMS
Sanity or Contentful for editorial content — landing pages, blogs, banners, and campaign content managed by your team without a developer.
Search & Discovery
Algolia or Shopify Search & Discovery for fast, relevant product search with filters, facets, personalisation, and analytics.
Checkout & Payments
Shopify Checkout (extensible via UI extensions). Stripe or Shopify Payments for subscriptions, split pay, and B2B invoicing.
Analytics
GA4, Shopify Analytics, and optional PostHog for session replay and funnel analysis. GTM for tag management.
Email & CRM
Klaviyo for email marketing and abandoned cart. Segment or Attio for customer data unification.
Security & Auth
NextAuth.js for customer accounts. Role-based access for B2B buyers. SOC 2-compliant infrastructure on Vercel + AWS.
