Our process
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.
01
Stage 01
Discovery & Audit
Brand, audience, competitive landscape, and conversion goals mapped in week one. If you have an existing store, we benchmark Core Web Vitals, accessibility, and merchant editability so we know exactly what to keep and what to rebuild.
What you'll get
- Brand & competitor audit
- Core Web Vitals benchmark
- Accessibility review
- Conversion goal map
02
Stage 02
Design & Prototype
High-fidelity Figma, every section, every breakpoint, every state. Reviewed in shared working sessions; signed off before a single line of Liquid is written.
What you'll get
- High-fidelity Figma design
- Every section & breakpoint
- Shared review sessions
- Sign-off before build
03
Stage 03

What you'll get
- Hand-written Liquid build

04

What you'll get
- Zero-downtime cutover
- Post-launch monitoring
- 30-day iteration window

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.
Most custom themes ship in 6–10 weeks from kickoff to launch, discovery and audit in week one, high-fidelity Figma next, then hand-written Liquid, QA, and a zero-downtime cutover. Section extensions on an existing theme are usually a 2–4 week turnaround.
Yes. We build to Shopify standards so Klaviyo, Judge.me, Recharge, Loop, Gorgias, and the rest keep working. Where an app is heavy, we load it deferred or replace it with native theme code so it never drags down Core Web Vitals.
Absolutely, that's the whole point of Online Store 2.0. Every section, block, and setting is exposed in the theme editor, so your team swaps heroes, adds collections, and ships campaigns without touching code. You also get merchant docs on day one.
Both. We can design from scratch in Figma, every section, breakpoint, and state, or build pixel-perfect from a design you already have. Either way you sign off on the full design before a single line of Liquid is written.
When Liquid genuinely hits its ceiling: complex personalisation, a content-heavy front end, or millisecond TTFB at scale. We build Hydrogen storefronts on Oxygen with React, keeping Shopify's native checkout and commerce APIs intact. For most merchants, a lean Liquid theme is faster to ship and cheaper to run, we'll tell you honestly.
Yes, Core Web Vitals green is a launch requirement, not a nice-to-have. LCP < 2.5s, CLS < 0.1, INP < 200ms, measured on real-user data. We monitor in production and fix any regressions inside the 30-day warranty window.
You get 30 days of post-launch support and a 30-day iteration window for refinements, plus merchant docs and training. Many clients continue on an optional monthly retainer so we keep evolving the theme, ship seasonal sections, and watch performance.
Section extensions on an existing theme typically start around AUD $3–6k. A full custom theme build generally lands in the AUD $12–30k range depending on template count, integrations, and CRO scope. Hydrogen/headless is quoted per project. You get a fixed quote after the week-one discovery, no surprises.
Online Store 2.0 is Shopify's modern theme architecture: JSON templates, sections on every page, theme app extensions, and merchant-editable settings across the whole store. It replaced the old vintage themes where only a developer could make changes. Every theme we ship is OS 2.0.
Page builders get you live fast but add third-party scripts that slow the store, lock content into the app, and cap your design. A hand-coded custom theme is leaner, faster, fully owned, and free of monthly subscriptions, it pays back in speed, conversion, and no vendor lock-in.
Yes, Figma-to-Shopify is one of our core services. We translate your design pixel-perfectly into production Liquid, preserving spacing, typography, and motion, then wire every section into the theme editor so it stays editable.
Yes. We rebuild vintage Liquid templates as JSON templates with sections everywhere, port your content, blocks, and metafields cleanly, stage everything on a duplicate theme, QA end-to-end, and swap to live in a single click, with zero downtime and no design regressions.
Yes, we work with Plus merchants across Australia, including checkout extensibility, B2B/wholesale, Shopify Functions, and multi-store setups. Whether you're on Plus or standard Shopify, the build standards are the same: fast, accessible, and merchant-editable.
