Sound familiar?
Your standard Shopify plan is hitting its limits
Flash sales tank your site. Staff accounts are maxed out. You need higher API rate limits and the checkout customisation Plus unlocks — not another app workaround.
You're paying for Plus but using 20% of it
Checkout Extensions, Shopify Functions, Flow, Launchpad, Markets — Plus has powerful features that most stores never touch because nobody has time to set them up properly.
Migrating to Plus is a 3-month risk
Magento, BigCommerce, or even standard Shopify → Plus migrations break things when teams skip metafield mapping, 301 redirect planning, or treat product data as a CSV import.
Everything included
No hidden extras. No scope creep. Clear deliverables agreed upfront.
Checkout Extensibility Builds
Custom checkout UI extensions built with Checkout Extensibility — upsells, custom fields, trust badges, delivery date pickers. Real React components in the Shopify Plus checkout, not theme hacks.
Shopify Functions
Custom discount logic, payment method customisations, and shipping rate rules built with Shopify Functions. Replaces legacy Scripts, runs at edge speed.
Magento → Plus Migration
End-to-end migration including EAV → metafield mapping, 301 redirect chains, customer & order data preservation. The Fabric Co (50,000 products) migrated with zero lost orders.
Shopify B2B Portal
Native Shopify B2B with company accounts, net payment terms, custom catalogues, and tiered wholesale pricing. Plus's most underused feature.
Shopify Markets Setup
Multi-currency, multi-language, market-specific pricing configured and tested across regions. EUR, GBP, AUD, CAD, AED — all market-correct.
ERP / 3PL Integration
Shopify Plus connected to SAP, NetSuite, Brightpearl, ShipBob, or Linnworks via Admin API. Orders, inventory, and fulfilment synchronised both directions.
From brief to launch
Plus Audit
I audit your current Shopify setup against Plus capabilities and identify the highest-ROI improvements for your specific business.
Implementation Plan
A phased roadmap with clear deliverables, timelines, and dependencies. No surprises.
Build + Validate
I build in your Plus development environment and run load tests for checkout-critical flows before touching production.
Launch + Monitor
Staged rollout with traffic monitoring, error tracking, and a rollback plan ready if anything unexpected happens.

Questions before you commit
Shopify Plus unlocks: checkout customisation via Checkout Extensibility, Shopify Functions for custom discount and shipping logic, native B2B features, Launchpad for automated campaigns, Flow for store automation, and significantly higher API rate limits.
Yes — I handle the full migration including theme changes needed for Plus features, app audit (some apps are redundant on Plus), and implementation of Plus-specific features like checkout extensions and B2B.
Checkout Extensions are React components that render inside the Shopify checkout UI. They allow you to add upsells, custom fields, trust badges, delivery date pickers, and more — without hosting any checkout code yourself.
Shopify Markets lets you sell in multiple countries from one store — with local currency, local pricing, translated content, and market-specific tax rates all managed in the Shopify admin. I configure and test the full Markets setup.
Yes — I build integrations between Shopify Plus and your ERP (SAP, NetSuite, Brightpearl) or 3PL (ShipBob, Linnworks, etc.) via the Admin API, syncing orders, inventory, and fulfilment status in both directions.
Shopify Flow is a no-code automation tool available on Plus. I configure Flow workflows for tasks like auto-tagging high-value customers, fraud risk flagging, inventory alerts, and loyalty reward triggers.
Yes — this is one of Plus's biggest underused features. With Checkout Extensibility you can run real A/B tests on checkout layouts, payment method positioning, upsell offers, and trust signals. Hypothesis-driven conversion testing on a Plus checkout typically lifts checkout completion 5-15%. For full CRO scope including PDP and cart, see the dedicated Shopify CRO & A/B Testing service.
