A Storefront That Turns Browsers Into Buyers.

Custom Theme Development
We turn your Figma into a custom, conversion-ready Shopify theme — built around your brand, not a template.

Already on Dawn, Impulse, or another premium theme? We extend it with custom sections, components, and integrations — no rebuild required.

Themes engineered for Core Web Vitals — image optimisation, deferred scripts, critical CSS, and zero render-blocking resources. 90+ Lighthouse out of the box.
Mobile-First Responsive Design
Mobile drives 70%+ of Shopify traffic. Themes are designed and built mobile-up — touch targets, swipe gestures, sticky CTAs — desktop scales from that foundation.

Headless / Hydrogen Themes
When Liquid hits its ceiling, we build Hydrogen storefronts on Oxygen — React, edge-rendered, with Shopify's native checkout and commerce APIs fully intact.
Why Online Store 2.0?
Vintage themes lock you into developer-only edits. Online Store 2.0 puts every section, block, and setting in the theme editor — so your team adds collections, swaps heroes, and ships campaigns without touching code. It's where every modern, conversion-ready Shopify theme lives now.
Custom vs the alternatives
Custom theme vs. a pre-made theme
A $300 premium theme or a drag-and-drop page builder gets you live fast — then caps your speed, your design, and your conversion rate. Here's how a hand-coded custom theme compares.

What's included in our Shopify theme service
Explore every capability — custom Liquid theme builds, Online Store 2.0, Hydrogen, performance, accessibility, and conversion-optimised PDP & PLP design.
Custom Theme Development
We turn your Figma into a custom, conversion-ready Shopify theme — built around your brand, not a template.
Figma → Liquid
Pixel-perfect translation from Figma to production Liquid — spacing, typography, motion, all preserved.
Clean Liquid Code
Production-grade Liquid + JS, written to last — no bloated frameworks or copy-paste code. Every theme passes Shopify Theme Inspector.
Editable & Supported
Every section is editable from the theme editor — no developer needed — plus dedicated post-launch support whenever you need a hand.
Theme Customisation & Extensions
Already on Dawn, Impulse, or another premium theme? We extend it with custom sections, components, and integrations — no rebuild required.
Custom Sections
Bespoke sections layered onto your existing theme — featured collections, lookbooks, founder stories, and content blocks.
Reusable Liquid Components
Shared building blocks across your store — consistent design, faster updates, less code to maintain.
No-Code Editing
We add merchant-facing settings to your theme so your team can make future tweaks without a developer.
Performance-First Themes
Themes engineered for Core Web Vitals — image optimisation, deferred scripts, critical CSS, and zero render-blocking resources. 90+ Lighthouse out of the box.
Core Web Vitals Green
LCP < 2.5s, CLS < 0.1, INP < 200ms — measured on real-user data, not just lab synthetic tests.
Instant First Paint
Above-the-fold styles load first and the rest is deferred — so your store paints instantly, especially on mobile.
Smart Lazy Loading
Images, video, and heavy components load only when they're needed — faster first load, no wasted bandwidth.
Mobile-First Responsive Design
Mobile drives 70%+ of Shopify traffic. Themes are designed and built mobile-up — touch targets, swipe gestures, sticky CTAs — desktop scales from that foundation.
Designed for Thumbs
44px minimum tap targets, sticky add-to-cart bars, and full-bleed, swipeable product galleries.
Per-Breakpoint Layouts
Mobile, tablet, and desktop layouts crafted independently — never just shrunk down from the desktop design.
Mobile-Network Tuned
Smaller images, lighter JS, deferred non-critical assets on mobile networks — fast even on 3G.

Accessibility (WCAG 2.1 AA)
Themes built to WCAG 2.1 AA — keyboard navigation, screen-reader semantics, focus states, colour contrast, ARIA. Inclusive for every shopper, standards-compliant, and better for SEO.
Semantic HTML & ARIA
Proper landmarks, heading hierarchy, and ARIA roles where needed — works with screen readers and assistive tech out of the box.
Keyboard-Navigable
Every interactive element reachable and operable by keyboard alone — modals trap focus, escape closes properly.
Auditable & Tested
Axe + Lighthouse + manual keyboard QA on every key template — accessibility report included on launch.
Conversion-Optimised PDP & PLP
Product and collection pages designed around what actually moves conversion — galleries, social proof, sticky CTAs, smart filters, and clear hierarchy.
Premium PDP Layouts
Sticky media galleries, variant pickers, urgency cues, social proof, and product recommendations tuned to lift your AOV.
Filterable PLP
Fast, faceted collection filtering powered by Shopify's Search & Discovery API — no third-party app bloat.
CRO Patterns Baked In
Trust badges, returns messaging, free-shipping thresholds, and review aggregates positioned exactly where they convert.
Theme Migration & Modernisation
Stuck on a vintage theme or an older Shopify build? We migrate you to Online Store 2.0 — keeping your design while gaining flexibility, performance, and merchant-editability.
Vintage → OS 2.0
Old Liquid templates rebuilt as JSON templates with sections everywhere — no design regressions.
Content & Metafield Migration
Existing content, sections, blocks, and metafields ported cleanly — nothing lost, nothing forgotten.
Zero-Downtime Cutover
New theme staged on a duplicate, QA'd end-to-end, then swapped to live in a single click — zero downtime.
Headless / Hydrogen Themes
When Liquid hits its ceiling, we build Hydrogen storefronts on Oxygen — React, edge-rendered, with Shopify's native checkout and commerce APIs fully intact.
Hydrogen + Oxygen
React Server Components on Shopify Oxygen edge — millisecond TTFB globally, all the Shopify commerce APIs.
Storefront API
GraphQL Storefront API as the data layer — products, collections, cart, customer accounts, all type-safe.
Modern DX
TypeScript, Tailwind, Vite, and full preview deployments — a modern developer experience built for production ecommerce.
Not sure if you need a rebuild or just sections?
We audit your current theme in week one — Lighthouse, accessibility, editability, code health — and tell you honestly whether to extend or rebuild.
Built on the tools modern Shopify themes run on.
Native Liquid where it shines, Hydrogen where edge performance matters, and modern dev tooling on every project — version-controlled, profiled, and CI-deployed.

How We Build Themes That Ship & Stay.
Four phases — discovery to launch — with weekly check-ins, shared Figma, a live preview URL, and merchant docs on day one.

Frequently asked questions
- If you're under $500K revenue and your brand is still finding its visual identity, a premium theme like Dawn or Impulse is the right call — we can extend it. Above $500K, or any brand where design is a competitive lever, custom pays back fast in conversion lift and editability.
