§00 / SHOPIFY PLUS · ENTERPRISE IMPLEMENTATION

Shopify Plus.
Enterprise commerce, without the enterprise drag.

Shopify Plus builds for brands running several markets, wholesale and retail side by side, or a checkout that has to do more than take payment. We design the architecture first, then build it with checkout extensibility, Functions and Flow.

Built for established brands doing $100K+ a year in online sales.

What a Plus engagement delivers.

Markets & expansionExpansion stores or Shopify Markets, with currencies, domains, duties and localised content planned together.Market-by-market QA
Checkout extensibilityCheckout UI extensions and Shopify Functions for discounts, delivery and payment rules, replacing checkout.liquid.Upgrade-safe
B2B on ShopifyCompany accounts, catalogues, price lists, payment terms and a wholesale experience that shares one admin.Role-based testing
AutomationFlow workflows, Launchpad events and integrations that remove manual operations work.Documented runbooks

Plus stores rarely live alone. ERP, PIM, 3PL and CRM integrations are mapped before a line of code is written, so data has one owner and one direction.

FIG. 02 — INTEGRATION MAP

Changes ship like software.

Enterprise stores carry real revenue every hour, so we treat releases accordingly: version-controlled themes, preview environments, staged rollouts and a rollback point for every publish.

If you are moving to Plus from another platform, migration planning, redirect mapping and a rehearsed cutover are part of the same plan rather than a separate project.

A few things, clarified.

Do we actually need Shopify Plus?

Not always. Plus earns its cost with B2B, multiple expansion stores, checkout customisation, higher API limits and automation needs. We look at your operations and tell you plainly whether standard Shopify would do.

Can you migrate our checkout.liquid customisations?

Yes. We audit what the old checkout does, then rebuild each behaviour with checkout UI extensions, Functions or apps, and test the full purchase journey before switching over.

How do you handle multiple markets?

We decide between Shopify Markets and expansion stores based on catalogue, pricing, fulfilment and content differences, then design a structure your team can operate without duplicating work.

Can you work alongside our in-house team?

Yes. We often own architecture and complex builds while internal teams handle content and merchandising, with shared repositories, code review and documentation.

the brief.

A new store. A difficult migration. The thing your current stack can’t do.
Let’s make a plan.
