Overview

Platform migrations done badly are devastating. We have audited brands who lost 30 to 40 percent of organic traffic, corrupted their customer history, broke attribution, and watched twelve months of paid media learning evaporate — all in a single poorly executed migration. Most of that damage is preventable, and almost all of it traces back to the same three things: a redirect map written in a panic the week of launch, a data migration nobody validated end-to-end, and tracking that was rebuilt as an afterthought rather than designed in from the start. We do this differently. Every Shopify Plus engagement begins with a pre-migration audit, a written risk register, and a redirect-and-data plan signed off before a line of theme code is written. Whether you are moving from Magento, WooCommerce, BigCommerce or Salesforce Commerce Cloud, building a headless Hydrogen storefront, replatforming a multi-region B2B operation, or commissioning your first Shopify Plus theme, the same senior people own it from discovery through to the 30-day post-launch review.

Platforms we migrate from

Off the platform that is holding you back, onto Shopify Plus.

Every platform has its own data schema, its own SEO traps and its own migration footguns. We have seen the lot. Each project starts from a written audit, not a sales deck.

Magento 1 & 2 / Adobe Commerce

Catalogue depth, attribute mapping, EE-only features rebuilt natively.

WooCommerce / WordPress

Plugin sprawl rationalised. Order history and customer data preserved.

BigCommerce

Storefront APIs, custom fields and price-list logic mapped cleanly.

Salesforce Commerce Cloud

Enterprise-grade replatforming with controlled cutover and parity testing.

Custom Symfony / Laravel

Bespoke schemas exported, normalised and imported with full validation.

Earlier Shopify / Shopify Plus

Theme rebuilds onto OS 2.0, Hydrogen storefronts, Checkout Extensibility.

What we build

Custom Plus, headless Hydrogen, B2B and multi-region.

We do not pitch the same build to every brand. We pick the right architecture for your catalogue, traffic, regions, team and roadmap.

Custom Shopify Plus theme builds

Bespoke OS 2.0 themes with a structured component system, JSON templates and merchandising flexibility editors actually use.

Headless on Hydrogen and Next.js

Performance-first storefronts for brands with multi-front-end, deep CMS or international rollout requirements. Only when there is a real reason.

Checkout Extensibility & Shopify Functions

Discounts, validations, payment and shipping logic implemented natively, replacing legacy checkout.liquid customisation.

B2B on Shopify Plus

Customer-specific catalogues, price lists, net payment terms, draft orders and approval flows. Hybrid B2B/D2C rollouts handled.

Multi-region and Markets

Multi-currency, multi-language and tax-inclusive pricing rollouts with Shopify Markets. Domain, hreflang and Merchant Center cleanly mapped.

ERP, OMS, PIM and 3PL bridges

NetSuite, Linnworks, Brightpearl, Akeneo and your 3PL of choice. Real-time stock, order and customer flow without spreadsheets.

Analytics rebuilt into the migration

GA4, server-side tagging, consent mode, Shopify pixel and platform events designed in, not bolted on after launch.

Performance and Core Web Vitals

Image, font, third-party script and Liquid render audits as part of every build. Real-user metrics tracked from day one.

The risks we eliminate

Most migrations fail in the same predictable ways.

A written risk register, signed off before kick-off. Every risk has a named owner, a mitigation, and a verification step before launch.

  1. Organic traffic collapse

    Without a complete URL-level redirect map and metadata parity, 30 to 40 percent of organic revenue can disappear in the first 90 days.

  2. Corrupted customer history

    Orders, addresses, subscriptions and tags imported without validation create accounts customers cannot recover from.

  3. Broken paid media attribution

    Tracking rebuilt as an afterthought destroys audience continuity and twelve months of platform learning.

  4. Checkout regressions

    Tax, shipping, payment and discount logic moved without parity testing causes silent revenue loss for weeks.

  5. Performance degradation

    A theme that scores 35 on PageSpeed after launch costs conversion rate every single day until it is fixed.

  6. App stack sprawl

    Carrying redundant apps onto Plus inflates cost, slows the storefront and complicates support.

Our process

How we work.

Audit

A full audit of your current platform before anything else. URL structure, SEO performance, top organic landing pages, data schema, integrations, analytics setup, custom development, and every third-party app. Every risk is documented in writing.

Plan

A migration plan covering data mapping, redirect strategy, theme approach (Plus OS 2.0 or headless), app stack rationalisation, analytics rebuild, and a launch timeline with named owners. Signed off by you before any code is written.

Data and redirects

Product, customer, order and subscription data exported, transformed and dry-run-imported into a staging Shopify Plus environment. Full 301 redirect map generated from your live crawl, validated against the top 1,000 organic landing pages.

Build

Theme or headless build on staging. Apps integrated, checkout configured, B2B and multi-region rules applied, ERP/OMS connections established. Senior engineers across front-end, Liquid, Hydrogen and Shopify Functions.

Analytics rebuild

GA4, server-side tagging, consent mode, Shopify pixel and platform-specific event tracking rebuilt as part of the migration, not after launch. Attribution and audience continuity preserved for paid media.

QA and parity

Side-by-side parity audit on content, product data, prices, taxes, shipping, customer accounts, and SEO. Pre-launch crawl comparison against the live site. Performance and Core Web Vitals validated.

Launch

Coordinated DNS cutover at a low-traffic window with senior engineers on call. Redirect verification, analytics validation, Merchant Center checks and a defined 48-hour post-launch support window.

Monitor

30-day post-launch monitoring against the pre-migration baseline. Organic traffic, rankings, conversion rate, revenue, and tracking parity. A written close-out report rather than a fade-to-silence.

FAQs

Common questions.

How long does a Shopify Plus migration take?
Most projects run six to twelve weeks from audit sign-off to launch. Catalogue size, B2B complexity, multi-region rollout, custom Shopify Functions and headless builds all add time. We give you a fixed timeline before we start, with named owners against every workstream.
Will we lose SEO rankings during the migration?
Not if it is done properly. We crawl the existing site before any work begins, map every indexable URL to its Shopify equivalent, preserve metadata and schema, and run a pre-launch and post-launch crawl comparison. Organic traffic is one of the metrics we report on for thirty days after launch against your pre-migration baseline.
Which platforms do you migrate from?
Magento 1 and 2 (Adobe Commerce), WooCommerce, BigCommerce, Salesforce Commerce Cloud, Volusion, custom Symfony or Laravel builds, and earlier versions of Shopify. Each platform has its own data schema and integration quirks. We have handled them.
Do you build custom Shopify Plus themes or use a starter?
Both, depending on what serves your brand and timeline. For luxury and premium retailers we usually build custom on Shopify OS 2.0 with a structured component system. For faster rollouts we extend a strong base theme and customise where it matters. We never recommend a build approach until we have audited your design and product requirements.
Can you build a headless Shopify storefront?
Yes. We work with Hydrogen, Next.js and other headless stacks where there is a real reason to go headless — extreme performance requirements, multi-brand front-ends, deep CMS integration, or international rollouts. We will tell you honestly when a Plus OS 2.0 theme is the better answer.
Do you handle B2B and wholesale on Shopify Plus?
Yes. B2B on Shopify Plus, customer-specific catalogues and price lists, net payment terms, draft orders and approval flows, plus integrations with ERP and OMS systems. We have run B2B-only and hybrid B2B/D2C rollouts.
What happens to our analytics and paid media tracking?
Tracking is rebuilt as part of the migration, not afterwards. GA4, server-side tagging, consent mode, the Shopify pixel and platform-specific events are designed in from day one. Audience continuity for Google, Meta and TikTok is preserved so you do not lose twelve months of paid media learning on launch day.
Do you work with our existing app stack or rebuild it?
We rationalise. Most pre-migration audits find apps doing redundant work, apps slowing the storefront, and apps that no longer serve the business. We keep what works, replace what does not, and integrate what you actually need: typically Klaviyo, Gorgias, Recharge, Yotpo, Searchanise and Triple Whale, plus your ERP, OMS, PIM and 3PL.
Where are you based?
Worksop, Nottinghamshire. Our senior engineers work remotely with on-site presence for kick-offs, workshops and key launches. King's Cross is ninety minutes from our office.
Who actually does the work?
The senior people who win the engagement are the senior people who deliver it. No junior account handover, no offshore relay, no agency theatre. You speak directly to the engineers responsible for the build.
