From a first Shopify launch to a full Magento enterprise rebuild — CzarGroup Technologies has been building high-performance eCommerce stores since 2009. We don’t do cookie-cutter. We do commerce that converts.

Platforms. One Expert Team
You’ve got good products. You’ve got traffic. But somewhere between your homepage and the checkout button, customers disappear. This isn’t a product problem — it’s a platform problem. A store that wasn’t built for your business, your customers, or your growth plans will always hold you back, no matter how much you spend on ads.
We’ve worked with enough merchants to know that most eCommerce headaches start the same way: an off-the-shelf theme that won’t flex, integrations cobbled together with duct tape, and a platform that starts showing cracks the moment order volumes pick up. If any of that sounds familiar, you’re in the right place.
CzarGroup builds eCommerce stores from the ground up — or takes what you already have and makes it actually work. That means clean architecture, real integrations, and a storefront that reflects how your customers want to shop.
These are the problems we fix most often:
Whether you’re launching, scaling, or rebuilding — we cover the full spectrum of eCommerce development across every major platform and architecture.
Our flagship. Czargroup has been a certified Magento agency since the early days of the platform. We build complex, multi-store Magento environments that handle high SKU counts, B2B pricing rules, custom checkout flows, and everything in between. Whether you're on Magento 1 and need a migration path or planning a headless Adobe Commerce rollout, we've done it before — properly.
Shopify works brilliantly when it's set up right. We build custom themes, extend Shopify's native functionality with purpose-built apps, and configure Shopify Plus for brands that need advanced scripting, B2B storefronts, or multi-market expansion. Fast to launch, built to grow.
When you need the flexibility of WordPress with the power of a proper eCommerce engine, WooCommerce is the answer — if it's built correctly. We develop bespoke WooCommerce stores with custom product types, subscription systems, complex shipping rules, and performance optimisations that keep your store snappy even as the catalogue grows.
Decoupling your frontend from your commerce backend unlocks performance and flexibility that traditional storefronts can't match. We build headless eCommerce solutions using React and Vue.js on the frontend, paired with Magento, Shopify, or BigCommerce as the commerce engine. The result is sub-second page loads, fully custom UI, and content experiences that convert.
BigCommerce sits in a sweet spot for fast-growing merchants who want enterprise capability without enterprise complexity. We build on BigCommerce for clients who need native multi-channel selling, strong B2B features, and a platform that doesn't require a developer every time you want to change a price. Customised themes, custom checkout, API integrations — all of it.
More than half of your customers are shopping on their phones. We build Progressive Web Apps and native mobile commerce experiences using Flutter and React Native — fast, offline-capable, and indistinguishable from native apps. Your mobile store should feel like it was designed for mobile, because it was.
Moving from an old platform is always risky if you don't know what you're doing. We've run dozens of migrations — Magento 1 to 2, OpenCart to Shopify, WooCommerce to Magento — without losing SEO rankings, order history, or customer data. We plan it properly, test it thoroughly, and launch it without the horror stories.
Your store doesn't exist in isolation. We integrate eCommerce platforms with SAP, Microsoft Dynamics, Salesforce, NetSuite, custom ERPs, and warehousing systems — so stock levels sync in real time, orders flow without manual intervention, and your ops team isn't copying data between spreadsheets. Clean integrations, reliable data.
AI isn't a feature you add to an eCommerce store — it's something you build into it from the start. We develop product recommendation engines, AI-driven search, dynamic pricing tools, and personalisation layers that adapt to individual shopper behaviour. Paired with our AI Solutions practice, we help brands use data they're already collecting to sell more intelligently.
We don't touch templates. Every store we build gets a design that's specific to the brand, the audience, and the buying journey. Our UI/UX designers think in conversion flows — every layout decision, every CTA position, every product page structure has a reason behind it.
Selling online without visibility into what's actually happening is like driving without a dashboard. We set up GA4, connect Power BI reporting, and build custom dashboards that show you revenue by channel, abandoned cart rates, product performance, and customer lifetime value — in a format your team can actually use.
Launching your store is the beginning, not the end. We offer structured ongoing support for all platforms we work on — security patches, performance monitoring, bug fixes, feature additions, and a team who knows your codebase because they wrote it. No handoff to a stranger support queue.
Every industry has its own eCommerce quirks — buying cycles, compliance requirements, catalogue complexity, customer expectations. We’ve worked across enough sectors to know what good looks like in each of them.
High-volume catalogues, seasonal campaigns, size/colour variant management, loyalty programmes, and the constant pressure to deliver in-store experience online. We build retail stores that can handle Black Friday without falling over.
B2B eCommerce is its own discipline. Custom pricing per account, quote request flows, minimum order quantities, tiered discounts, credit terms, and purchase approval workflows. Magento and Shopify Plus both have strong B2B capabilities when you know how to configure them.
Complex configurable products, technical specs, and buyers who need accurate stock information before they commit. We build manufacturing eCommerce stores that connect directly to production and inventory systems.
Postcode-based delivery zones, slot management, product substitution logic, recurring orders. We’ve built online supermarket and grocery delivery platforms on Shopify and custom stacks — and we know where the complexity hides.
Subscription products, compliance-aware content, age verification, detailed ingredient information, and customer education flows. Health and beauty eCommerce needs more thought than most — we’ve put that thought in.
High-value items, complex product specs, comparison functionality, accessory cross-sells, and customers who do their research before they buy. We’ve built for camera equipment retailers, audio suppliers, and consumer electronics brands across the UK and US.
Course sales, digital downloads, subscription access, and the challenge of selling something customers can’t physically hold. We build eCommerce for training providers, publishers, and digital content businesses that need more than a basic checkout.
Order management, multi-warehouse stock allocation, carrier integrations, returns processing. When your eCommerce operation runs at volume, the back-office systems matter just as much as the storefront. We build both.
Backend Development
Cloud & DevOps
Payment Gateways & Financial Integrations
There are hundreds of eCommerce agencies. Most will tell you the same things. Here’s what actually differentiates how we work:
We were building on Magento when it was still version 1. We’ve seen every major platform shift, every algorithm update, and every wave of “the next big thing in eCommerce.” That context makes our recommendations sharper.
Most of our clients have been with us for years — not because we lock them in, but because they get results and the relationship works. A 90% retention rate in an industry known for project churn says something.
Fixed-scope project or dedicated development team — you choose what works for your business. We don’t try to sell you a retainer when you need a one-off build, and we don’t push for project-by-project when ongoing support would serve you better.
Our UK base means we understand the domestic market — payment preferences, delivery expectations, GDPR, and what UK customers expect from an online store. Our India team gives us delivery capacity and time-zone coverage that many UK-only agencies can’t match.
We’re not adding “powered by AI” to everything for the sake of it. But where AI genuinely improves search, personalisation, forecasting, or content generation within your store, we know how to implement it properly. See our AI Solutions practice.
A store that’s beautiful on launch but collapses under load is a liability. Every architecture decision we make considers where your business will be in two years, not just where it is today. We build for the growth you’re planning, not just the one you have.
No black boxes. You’ll know exactly where we are at every stage, what’s been completed, and what’s coming next.
We start by understanding your business, not just your brief. What are you selling, to whom, and how do they buy? What are the real bottlenecks? What does success look like in 12 months? This stage defines everything that follows.
Before a line of code gets written, we map out the platform, integrations, data flows, and infrastructure. We document assumptions and flag risks early — because surprises in week 8 are expensive for everyone.
Wireframes, user flows, and a full design system that covers your storefront across every device. We test assumptions against your actual customer journeys before handing anything to development.
Two-week sprints, regular demos, and a staging environment you can access throughout. We build incrementally and review often — which means issues get caught early and the final delivery rarely holds surprises.
Every build is load-tested, cross-browser tested, and put through a full checkout flow audit before it goes anywhere near a live environment. We test on the traffic volumes you’re expecting, not the ones you have today.
Launch day is planned, not improvised. We monitor closely in the first 72 hours and stay available. Once you’re live and stable, we move into a structured support arrangement that keeps your store healthy long-term.
Tell us what you’re trying to achieve. We’ll tell you whether we’re the right fit — and if we’re not, we’ll say so.
Honestly, it depends. Shopify is excellent for businesses that want to launch quickly and don't need heavy customisation — Shopify Plus extends this for enterprise volumes. Magento (Adobe Commerce) is the right choice when you have complex catalogue management, multiple storefronts, or B2B requirements that Shopify can't accommodate natively. WooCommerce works brilliantly for businesses already invested in WordPress. BigCommerce is strong for mid-market merchants who want scalability without the Magento overhead. We'll give you a straight recommendation after understanding your requirements — not the platform we happen to know best.
A Shopify store with a custom theme and standard integrations: 6–10 weeks. A mid-complexity Magento build with ERP integration and custom checkout logic: 3–5 months. A full enterprise Adobe Commerce implementation with multiple storefronts and headless frontend: 6–12 months. These are realistic estimates based on actual project history, not marketing promises. Timeline always depends on the scope you agree at the start and how quickly decisions get made on your side.
Yes — and we take it seriously, because most migration disasters happen when agencies don't. We plan URL redirects before we write a single line of migration code, we audit your existing traffic and rankings, and we run parallel environments so you can validate before anything goes live. We've completed migrations from Magento 1 to 2, OpenCart to Magento, WooCommerce to Shopify Plus, and several platform-to-headless projects without significant ranking losses.
Yes — and most of our long-term client relationships started this way. We offer structured support retainers that cover security patching, performance monitoring, bug fixes, and development of new features. The team that maintains your store is the same team that built it, which means they already know the codebase and don't need to spend the first month of your retainer getting familiar with it.
This is one of the most common requirements we work on. We've integrated eCommerce platforms with SAP, Microsoft Dynamics NAV and Business Central, Sage, NetSuite, custom-built warehouse management systems, and various 3PL APIs. The integration approach — whether that's direct API connection, middleware, or event-driven sync — depends on your systems and how real-time the data needs to be. We scope these carefully before quoting, because integration complexity is where budgets often run over.
Headless commerce separates your frontend (what customers see) from your commerce backend (Magento, Shopify, etc.), connecting them via APIs. This gives you complete design freedom, faster page loads, and the ability to deliver commerce experiences across different surfaces — websites, apps, kiosks, voice. Most businesses don't need it. But if you're running a content-heavy brand, have a complex multi-channel strategy, or are hitting the performance ceiling of your current theme, it becomes worth considering. We'll tell you honestly whether it's right for you.
Yes. While we're based in Coventry, UK, we serve clients across the US, Europe, India, and the Middle East. The majority of our project work is conducted remotely via structured processes, regular video calls, and shared project management tools. Time zone differences are manageable; lack of communication isn't — we're clear about that from day one.
SEO is factored in from the start of a build — not added as an afterthought. This covers URL structure, page speed, structured data markup, canonical tags, crawl budget management, and metadata frameworks. For migrations, we carry out a full pre-migration SEO audit and implement redirect mapping before any URLs change. We also connect with your digital marketing team or work with our own to ensure the transition doesn't create traffic gaps. Explore our Digital Marketing services for post-launch SEO support.
Ranges vary significantly depending on platform, complexity, and scope. A custom Shopify build starts from around £8,000–£15,000. A mid-level Magento project typically runs £25,000–£60,000. Enterprise Adobe Commerce or headless implementations start from £80,000 and scale from there. We don't publish fixed price lists because every project is different — but we're upfront about budget ranges during the initial conversation so you can decide whether to proceed before anyone invests time in a detailed proposal.
Yes. Beyond building the store, we offer Google Shopping management, paid search, SEO, and Power BI analytics through our broader service offering. Explore our Digital Marketing services and Power BI reporting capabilities for more detail.
Whether you’re starting from scratch, rescuing a struggling store, or planning a platform migration — we’d like to hear about it. No hard sell. Just an honest conversation about what you need and whether we’re the right people to deliver it.
