Build · Custom Shopify storefronts engineered to convert, not decorate

Shopify stores built to convert

Custom Shopify storefronts that hit sub-2.5s mobile LCP at launch, ship with a recorded conversion baseline so the redesign can be proved or disproved, and stay editable by your merchandiser without opening a ticket. No page-builder bloat, no agency lock-in.

The problem

Why most Shopify builds underperform

  • Your theme was bought, not built, so every new landing page needs a developer.
  • Mobile LCP sits above 4 seconds and shoppers leave before the hero image lands.
  • Product pages render the same six sections whether the item costs $18 or $480.
  • Nobody recorded a pre-launch baseline, so nobody can prove the redesign worked.

Most Shopify stores are a bought theme with the colours changed. They look fine and they convert at 1.1%. The distance between a 1.1% store and a 2.8% store is not decoration. It is merchandising logic, page weight, and a checkout path with the friction taken out.

We build both sides at once: a storefront customers move through without thinking, and a theme your marketing team can edit without opening a ticket. Every section is a native Online Store 2.0 block. Every template is documented. Every build ships with GA4, consent mode, and a recorded baseline so the words 'it's doing better' become a number.

Scope

What you actually get

No line item here is optional-extra padding. This is the standard shape of the engagement.

01

Conversion-Led UX & Wireframes

Wireframes for home, collection, product, cart and checkout drawn from your own session recordings, site-search logs and support tickets. Not a template library.

02

Custom Online Store 2.0 Theme

A bespoke theme in clean, commented Liquid with modular sections your team can rearrange themselves. Zero dependency on page-builder apps.

03

Merchandising & Navigation System

Collection architecture, filtering, badging and cross-sell rules mapped to how your catalogue actually sells. Bestsellers surface; dead stock stops eating grid space.

04

Speed Budget & Core Web Vitals

Image pipeline, third-party script audit and app cleanup enforced against a hard budget: LCP under 2.5s on 4G mobile, CLS under 0.1, INP under 200ms.

05

Catalogue & Content Load

Products, variants, metafields, collection copy and redirects loaded and QA'd in a dev store before cutover. You review a real store, not a Figma file.

06

Launch, Handover & Documentation

Loom walkthroughs, a written theme guide and 30 days of post-launch fixes included. Your team owns the store from day one.

How it runs

The engagement, step by step

You will always know what week you are in and what lands next.

01

Discovery & Data Pull

Two weeks inside your analytics, heatmaps, site search and support inbox. We leave with a ranked list of what is currently costing you revenue.

02

Architecture & Wireframes

Sitemap, template inventory and grey-box wireframes for every page type. Signed off before a single pixel gets designed.

03

Design System

Figma component library, type scale and every awkward state: empty cart, sold out, pre-order, bundle, back-in-stock, subscription upsell.

04

Build & QA

Liquid development in a dev store, tested on real devices and against your live app stack. Accessibility checked to WCAG 2.1 AA.

05

Launch & Measure

Redirect map, tracking validation, DNS cutover on a low-traffic window. Then 30 days of monitoring against the pre-launch baseline.

Quoted per engagement, never off a rate card

We do not publish a price for this, because the honest number depends on your catalogue, your stack and how much of the work is already done. You get a fixed statement of work with named deliverables and named dates before anyone starts — and we will tell you plainly if this is not the right first move for your brand.

Performance Apparel (DTC)

~$6M/yr DTC, 900+ SKUs across size and colour variants, US · Shopify Plus

Returns ran at 31% and refund cost consumed the entire paid media margin. One size chart image served 40 different fits, and 62% of add-to-carts started on a collection page that never showed variant availability. The named constraint: no new product photography budget, so every fix had to come out of the existing asset library and the review corpus.

31% → 22%return ratenine-point drop, roughly $310k/yr in recovered margin
1.9x → 2.4xblended MERwith paid spend held flat throughout

What we did

  • Rebuilt the PDP around fit. Per-fit sizing tables, model height and size worn, and inline runs-small/true-to-size data mined from 4,100 existing reviews.
  • Put variant-level availability and colour swatches on collection cards so shoppers stopped landing on sold-out PDPs.
  • Replaced the cart page with a slide-out drawer, a free-shipping threshold set at AOV plus 18%, and exactly one relevant cross-sell.
  • Rebuilt both ad channels around contribution margin and blended MER instead of platform ROAS. On Google, restructured the Shopping feed around fit and live variant availability so out-of-stock sizes stopped absorbing budget, and split brand from non-brand search. On Meta, killed six of eleven prospecting audiences and rebuilt the catalogue feed off the same variant data.
“Nobody had told us returns were a merchandising problem, not a product problem. Fixing the size chart made us more money than the ad account did.”Founder, Performance Apparel Brand

Home Goods & Furniture

~$11M/yr, 2,300 SKUs, configurable upholstery, US · Shopify Plus + Hydrogen storefront (Oxygen)

Fabric, leg and size options turned 2,300 SKUs into more than 40,000 variant permutations, and the Liquid theme rendered a configurable PDP in 6.9 seconds on mobile. Collection filtering ran client-side, so 40% of shoppers left before the first product painted. The named constraint: the ERP stayed. It was the single source of truth for stock and lead times and was not up for replacement.

What we did

  • Ran the paid growth audit first. Session recordings, funnel analysis and a prioritised revenue roadmap put configurator latency at #1. The redesign the client walked in asking for ranked #7.
  • Built a Hydrogen/Oxygen storefront with server-rendered faceted collection pages and an edge-cached configurator.
  • Integrated the existing ERP through a middleware layer for real-time stock and per-SKU lead times on the PDP. No ERP replacement, no data migration risk.
  • Preserved the full URL structure and rebuilt product and breadcrumb schema so the headless cutover carried zero SEO debt.

In their words

What clients said afterwards

AOV $58 → $79

“Full rebuild in 11 weeks, launched two days before Black Friday, which was an aggressive ask and probably a stupid one on my part. They pushed back hard on three homepage ideas I was attached to and were right about all three. AOV went from $58 to $79, mostly off the bundle builder they put on the product page.”

FAQ

Design & Build — straight answers

Eight to twelve weeks for most brands, from kickoff to live. A single-catalogue store with clean product data lands closer to eight. Add subscriptions, B2B, or a multi-market rollout and you are looking at fourteen to eighteen. We give you a dated Gantt in week one and update it weekly.

We build on Shopify's Dawn reference theme and replace the sections we need. That gives you Shopify's own performance and accessibility baseline plus a codebase that survives platform updates. Premium themes carry code you will never use and cannot safely delete.

That is the point. Every content block is a native theme section with a schema your merchandiser can configure in the theme editor. You get a written guide and recorded walkthroughs. If you still need us for a homepage change, we built it wrong.

We audit every installed app for cost, script weight and overlap. Most stores we take on are running four to seven apps that duplicate each other or are no longer used. Removing them is usually the cheapest speed win available and it lands before design starts.

Yes, and sometimes that is the right call. If your brand work is strong and the problem is speed, structure or editability, a like-for-like rebuild costs less and ships faster. We will tell you in the audit which of the two you actually need.

Thirty days of bug fixes are included in every build. After that most brands move onto a growth retainer that covers the CRO backlog, app management and new feature work. It is optional, and we do not hold your theme hostage either way.
