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.
-
1
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.
- Brand & competitor audit
- Core Web Vitals benchmark
- Accessibility review
- Conversion goal map
-
2
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.
- High-fidelity Figma design
- Every section & breakpoint
- Shared review sessions
- Sign-off before build

Ready for a theme that earns?
Free theme audit covering Lighthouse, accessibility, merchant editability, and code health. We’ll show exactly where to invest, and where to leave well enough alone.
Get a free theme auditIf 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.
A typical custom theme runs 6–10 weeks end to end, depending on catalogue size, integrations, and how ready your content is. Smaller section work and CRO sprints are faster. We commit to a schedule after discovery, not before.
Yes. We audit your installed apps during discovery and build around the ones that earn their place, using theme app extensions and app blocks so updates don’t break your storefront. Where an app is slowing you down, we’ll say so and suggest a lighter path.
Either. We design in high-fidelity Figma covering every section, breakpoint, and state, or we build pixel-perfect from a design you already own. If you bring your own, we review it for conversion and accessibility before build starts.
That’s the point of building on 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 or waiting on a developer.
You own the code outright, so you can keep editing through the theme editor indefinitely, and any developer can pick it up. We hand over documented, commented Liquid plus merchant docs at launch.
None on your side, the theme editor is unlimited. On ours, project scope covers the agreed build plus a 30-day iteration window for refinements. Beyond that, ongoing changes are covered by a retainer or quoted per piece of work.
The Shopify theme editor for day-to-day content and layout, metafields and metaobjects for structured content, and merchant-facing section settings we add specifically for your team. No page-builder app required.
No. Content, sections, blocks, and metafields are migrated cleanly and QA’d on a duplicate theme before anything goes live, so nothing is lost and nothing is overwritten.
Every build is version-controlled and staged on a duplicate theme, so rolling back is a single click in Shopify. We keep the previous live theme intact after cutover until you’re happy.
