Shopify Theme Development

We build custom Shopify themes from a clean section architecture — modular, responsive and fast — so your team can compose pages in the editor without touching code.

Overview

Themes built to be edited, not fought

EcomLabs builds Shopify themes the way modern themes like Dawn and Horizon are structured: modular sections, blocks and settings that merchants can rearrange in the theme editor. No hard-coded pages, no copy-paste sprawl.

We write Liquid that's readable and documented, so everyday changes stay in the editor and future work doesn't mean rebuilding from scratch. When you're on an old, patched theme, we migrate you to a clean Online Store 2.0 foundation.

Discuss your project

Editor-first

Sections, blocks and presets are set up so merchandising and content changes happen in the theme editor, not in code.

Fast by default

Lean Liquid, deferred scripts and image discipline keep Core Web Vitals healthy as the catalog grows.

Maintainable

Consistent naming, documented schema and reusable sections keep the theme easy to extend a year from now.

Process

How we deliver

  1. Audit & scope

    We review your current theme, catalog and content needs, then define a section architecture and clear milestones.

  2. Build sections

    We build the theme as modular sections and blocks in clean, documented Liquid with editor-friendly settings.

  3. QA & performance

    Cross-device QA, accessibility checks and performance tuning against real content and page weight.

  4. Handoff & support

    We document the theme, walk your team through the sections and provide post-launch support.

Use cases

Where this helps most

New custom theme

A bespoke theme built around your brand and merchandising, not a marketplace theme bent to fit.

Legacy theme migration

Moving off a vintage or heavily patched theme onto a clean Online Store 2.0 architecture.

Theme performance rescue

Reworking a slow, bloated theme into lean sections that pass Core Web Vitals.

FAQ

Shopify Theme Development

Do you build from scratch or start from Dawn?
Both are valid. For fully custom brands we build a bespoke theme; for tighter timelines we can start from a clean base like Dawn and extend it. We decide based on your scope and budget.
Can you migrate my old theme to Online Store 2.0?
Yes. We move vintage or heavily patched themes onto a modular Online Store 2.0 architecture, preserving your content and rebuilding pages as editable sections.
Will my team be able to edit the theme?
Yes. We build with sections, blocks and clear settings so merchandising and content changes happen in the theme editor, and we document the setup for your team.
