Mladen is a wizard! He has helped elevate my Shopify site to the next level with his coding experience and expertise. Things I thought could never be done due to the limitations with my store's theme, he made happen. His communication and response rate is fantastic, he is super skilled, and speaks in layman's terms so anyone can understand what he means. I only wish I knew about him years ago when I started my Shopify store! He's helped take my site to the next level and I couldn't be happier. I look forward to working with him for years to come. 10000% would recommend!
United Kingdom
Shopify Plus Agency for UK Brands
Trusted by Carl Friedrik, TramwayPath and other UK Shopify Plus merchants. Custom development, headless Hydrogen, B2B builds, and post-Brexit EU delivery — one timezone away from London.
Shopify Plus Partner since 2017
Built for UK and British brands
Codersy is a Shopify Plus Partner working with UK heritage, premium and DTC brands. Here is what UK merchants come to us for.
Built for British heritage and premium brands
We have shipped Shopify Plus and headless Hydrogen storefronts for premium UK brands like Carl Friedrik and TramwayPath. The bar is the same one that Mr Porter, Burberry and Aspinal of London set: type, photography, motion, performance.
One time zone away from London
Codersy is in Central European Time — exactly one hour ahead of GMT. Same-day Slack response, same-day calls, no async-only excuses. Your Tuesday morning standup happens at our 10am, not at our 4am.
Plus Partner with EU and UK delivery experience
Shopify Plus Partner since 2017, with project teams that have shipped for UK, EU and global merchants. Comfortable with VAT, HMRC reporting, post-Brexit shipping and the multi-store setups that come with it.
What we build for UK merchants
From Magento and BigCommerce migrations to headless Hydrogen storefronts, B2B portals and post-Brexit EU shipping — these are the engagements UK Shopify Plus brands come to us for most often.
Replatforming to Shopify Plus
Migrating from Magento, Adobe Commerce, BigCommerce Enterprise or Salesforce Commerce Cloud — with full data integrity, redirect mapping and SEO continuity. We have done this for UK and EU merchants more times than we have fingers.
Headless storefronts on Hydrogen
When stock Liquid hits its ceiling on motion, layout or performance, Hydrogen takes over. We build headless that the in-house team can keep evolving — not a black box that locks you in.
B2B and trade portals on Plus
Wholesale catalogues, account-gated pricing, tiered discounts, NET30 terms, ERP integration. The B2B feature set on Plus is mature now — we know which native features to use and which to build around.
Multi-currency, multi-region for UK + EU
GBP price lists, EUR / USD parallel pricing, Markets configuration, hreflang for /uk/ and /eu/ paths, and tax-included pricing handled correctly across regions.
Performance and Core Web Vitals
LCP, CLS and INP work that moves the needle on Google ranking and on conversion. We instrument, measure, and report against real-user data — not lab-only numbers.
Custom Shopify apps and integrations
Public and private apps, ERP and OMS integrations, subscriptions, fulfilment hooks, and the workflows that off-the-shelf apps refuse to bend to.
How we work with UK brands
Discovery call
A 30-minute call in your time zone — usually a Zoom or Google Meet. We map your goals, current stack, integrations, deadlines and budget. You get a written summary and rough timeline within 48 hours.
Scope, proposal and statement of work
Detailed scope, milestone breakdown and fixed-scope quote in GBP, EUR or USD. Statement of work signed off before any code is written — no expanding scope, no surprise invoices.
Build, launch, hand-over
Weekly demos, staging environment access from week one, and a launch playbook covering DNS, backups, redirects and post-launch monitoring. Documentation handed to your in-house team. Support continues after go-live.

UK-merchant FAQ
Yes — UK is one of our largest markets. We are the Shopify Plus partner behind carlfriedrik.com (premium leather travel accessories) and tramwaypath.co.uk (a fully automated prize-based ticketing platform that lifted ticket sales 28% post-relaunch). We have shipped for merchants across the UK and EU since 2017.
Central European Time — exactly one hour ahead of London. In practice this means full overlap during business hours: when London opens at 9am, we are already at 10am with three hours of work behind us. No async-only excuses, no end-of-day handovers across continents.
Yes. We invoice in GBP, EUR or USD depending on which works for your finance setup. UK BACS, SEPA and Wise are supported.
Yes — Codersy has been a Shopify Plus Partner since 2017, listed in the Shopify Partners directory with a 5-star rating from verified merchant reviews. We have shipped 500+ projects across 35+ industries, including Carl Friedrik (UK), TramwayPath (UK), Fisiocrem (Canada) and Lox & Chain.
We configure UK VAT correctly at the Markets level, including reverse charge for B2B EU sales and the 20% / 5% / 0% rate split where it applies. For Making Tax Digital we typically integrate Shopify with your existing accounting software (Xero, QuickBooks, Sage) rather than reinventing reporting inside Shopify.
Yes. We configure dual fulfilment (UK + EU warehouses where applicable), set up commodity codes and country-of-origin data per product, register IOSS for sub-€150 EU shipments, and integrate with carriers and 3PLs that handle EU customs cleanly. We have done this end-to-end for multiple UK Plus merchants.
We publish our prices in euros and quote in GBP, EUR or USD. A Shopify store build starts from €3,000, a custom theme built from your own design from €8,000, design plus custom theme from €9,000, and a migration from another platform from €5,000. Ongoing optimization starts from €500 a month. A headless Hydrogen storefront at standard scope costs €10,000–20,000. Shopify Plus builds and larger headless projects are quoted per project: we send a fixed price after the discovery call — no expanding scope mid-project. See our pricing.
A custom theme build is 6–10 weeks. A migration from Magento or BigCommerce is 10–16 weeks depending on data volume and integration count. A standard headless Hydrogen build takes 9–10 weeks; projects with several markets or integrations take longer. We commit to delivery dates after the scoping phase, not before.

Honestly, we had a really great experience working with this team. From the very beginning, they showed a lot of patience and understanding for all of our ideas, even when we weren’t always sure how to explain things clearly. What pleasantly surprised us the most is that they didn’t just do what was asked — they often suggested improvements and solutions we hadn’t even considered. In many cases, they put in extra time and effort just to make sure the website turned out better, more functional, and easier for customers to use. Communication was smooth and quick, and everything we agreed on was delivered without complications. In the end, we got a website that not only looks professional, but also feels simple and intuitive — which was the most important thing for us. Highly recommended.
