Shopify Plus Engineering

Builds, migrations, headless, B2B and international architectures.

Shopify Plus builds, migrations, headless and B2B architectures. Built by senior engineers, designed for conversion, maintained for the long run.

Our approach

How we work.

Idea to execution

Strategy, design, engineering, QA and AMC — delivered in-house by one team that owns the outcome end to end.

Shopify Plus, fluently

Functions, Scripts, Flow, checkout extensibility, multi-store and B2B. Plus is our native language, not a learning curve.

Migration without loss

Magento, SFCC, WooCommerce and custom stacks moved without losing SEO, history or trading days.

Built to compound

Modular section libraries, instrumented experimentation and AMC retainers that turn quarter-over-quarter into year-over-year.

The full practice, one engineering team.

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.

Performance & CRO

Core Web Vitals work, instrumented experimentation programmes and quarterly conversion lifts you can prove.

Shopify apps & integrations

Custom public/private apps, ERP/OMS/CRM middleware, PIM pipelines, payments and tax — stitched in cleanly.

The outcome

What you walk away with.

Engineer the storefront, and then keep engineering it. Sale events, replatforms, B2B rollouts and the quiet work in between — all handled by the same senior crew.

The deep dive

The hard mode

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.

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%.

Zero-drama migrations

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

Deep integrations

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

Headless at volume

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

Our process

Migration methodology

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

Audit

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

Architect

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

Migrate

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

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 surprises
Tested builds with peer review before anything ships
PCI and GDPR considerations built into every implementation
Senior engineers on every engagement, never subcontracted

Frequently asked

Questions, answered.

The things merchants ask before a migration or replatform — timelines, catalogues, partners and takeovers.

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.
