// what_we_build

Everything a serious brand needs on Shopify Plus.

One team across strategy, design, and engineering. No handoffs to subcontractors, no theme-shop shortcuts.

Shopify Plus builds

Storefronts engineered for scale, sale-event traffic, and zero tolerance for downtime.

Replatforming & migration

From Magento, SFCC, WooCommerce, Contentful, or custom. Data, SEO, and revenue preserved.

Headless & Hydrogen

Custom and Hydrogen storefronts for brands that have outgrown the theme layer.

B2B & wholesale

Customer-specific pricing, quote flows, and wholesale channels built into Plus.

International & Markets

Multi-currency, multi-region storefronts via Shopify Markets, built for cross-border growth.

Custom checkout & Scripts

Checkout extensions, Shopify Scripts, and bespoke logic where the catalogue demands it.

// hard_mode

The agency brands call when it has to work at scale.

Most agencies are fine until the catalogue gets large, the integrations get real, or the migration can’t lose a single order. That is where we do our best work.

01

Large catalogues

We migrated Pothys with 80,565 products, 229,635 customer records, and 163,466 orders mapped to Shopify metafields, with load times down 30%.

02

Zero-drama migrations

Heritage and high-traffic brands replatformed with SEO preserved, 301s mapped, and no downtime through sale events.

03

Deep integrations

ERP, OMS, PIM, search and support systems wired into Shopify through custom apps and middleware that hold up.

04

Headless at volume

End-to-end headless implementations engineered to handle more than a million users with custom, AI-powered modules.

// one_store / two_readers

Built for humans and AI agents alike.

A store has two readers now: the customer browsing it, and the AI agent reading it. We build storefronts that both understand, with structured product data, clean schema, and feeds that AI engines can find, parse, and recommend.

It is the difference between being visible and being invisible when buyers start asking an assistant what to buy.

// migration_methodology

A migration method built on rebuilds, not guesswork.

Replatforming is where revenue is won or lost. Ours is a documented process, run by senior engineers, with the plan as the first deliverable.

01

Audit

Map the current platform, catalogue structure, integrations, and every dependency before a line of code.

02

Architect

Migration runbook, data mapping to metafields, 301 strategy, and integration contracts. The plan is the deliverable.

03

Migrate

Products, customers, orders and history moved with integrity. Staged, tested, and validated against the source.

04

Go live

SEO preserved, redirects in place, no downtime. Then we stay, through managed services and continuous improvement.

Staging mirrors production so go-live holds no surprisesTested builds with peer review before anything shipsPCI and GDPR considerations built into every implementationSenior engineers on every engagement, never subcontracted
// flagship_build

Questions, answered.

How long does a Shopify Plus migration take?+
It depends on catalogue size and integration depth, but a typical mid-market migration runs a few weeks to a few months. We open every engagement with an audit and a migration runbook, so you have a realistic timeline before any code is written. Large, multi-system migrations are scoped in phases to protect revenue.
Can you migrate from Magento, SFCC, or a custom platform?+
Yes. We migrate from Magento, Salesforce Commerce Cloud, WooCommerce, Contentful, and fully custom stacks. Our process maps legacy data to Shopify metafields, preserves SEO with 301 redirects, and validates every product, customer, and order against the source before go-live.
Do you handle large catalogues and high-traffic stores?+
This is our core strength. We have migrated catalogues exceeding 80,000 products with hundreds of thousands of customer and order records, and built headless storefronts engineered for more than a million users. Sale-event traffic and zero-downtime go-lives are part of how we scope.
Are you a Shopify Plus Partner?+
Yes, a Shopify Plus Partner since 2015, with a 4.9 rating across 608 reviews on our Shopify Partner profile and further verified reviews on Clutch. Our work spans seven-plus Shopify-verified skills, from headless commerce to custom apps and migration.
Can you maintain a store you didn’t originally build?+
Yes. Many brands come to us to take over and stabilise a store built elsewhere. We audit it first, fix what needs fixing, then run it under managed services, with senior engineers, monitoring, and continuous improvement.
