What Our Shopify Developers Build
Custom Liquid themes, Shopify Plus checkout extensions, private app development, platform migrations with SEO preserved, Headless Shopify with Hydrogen, ERP and CRM integrations, CRO and performance optimisation, and ongoing Shopify retainers.
Custom Shopify Theme Development
Bespoke Shopify themes built from scratch using Liquid, JavaScript (ES6+), SCSS, and the Shopify Theme API — pixel-perfect implementation of your brand design system, fully responsive, WCAG 2.1 AA accessible, and optimised for Lighthouse performance. No off-the-shelf themes modified with hacks.
Shopify Plus Customisation
Shopify Plus implementation and customisation — Shopify Scripts and Functions for custom pricing, discount, and checkout logic; Shopify Flow automation; Launchpad campaign scheduling; B2B wholesale portal setup; Shopify Markets for multi-region/multi-currency; and custom checkout extensions via Checkout UI Extensions API.
Shopify App Development
Public and private custom Shopify app development using Shopify CLI, Remix/Node.js, App Bridge, Admin REST and GraphQL APIs, Storefront API, Checkout UI Extensions, Theme App Extensions, and Admin UI Extensions — following Shopify app review guidelines for App Store submission or private merchant use.
Shopify Headless (Hydrogen / Next.js)
Headless Shopify storefronts built with Hydrogen/Remix or Next.js + Shopify Storefront API — for merchants needing maximum front-end performance (Core Web Vitals), full design freedom beyond Liquid constraints, or Progressive Web App capabilities. Hosted on Oxygen (Shopify native) or Vercel/Netlify.
Migration to Shopify / Shopify Plus
End-to-end migrations to Shopify from WooCommerce, Magento, BigCommerce, PrestaShop, OpenCart, and custom PHP stores — products, variants, metafields, customers, historical orders, blog content, SEO URL mapping with 301 redirects, navigation rebuild, and payment gateway configuration on the new store.
Shopify Theme Customisation
Customisation of purchased Shopify themes (Dawn, Prestige, Impulse, Turbo, Ella, and others) — modifying existing sections, building new custom Liquid sections and blocks, fixing mobile responsiveness issues, adding custom JavaScript functionality, and integrating third-party widgets without slowing page load.
Shopify 2.0, Plus, Hydrogen & the Integration Ecosystem
Liquid, Shopify Plus (Scripts, Flow, Launchpad, Markets, B2B), Admin and Storefront GraphQL APIs, Hydrogen/Remix headless, Checkout UI Extensions, Shopify Functions, Klaviyo, Salesforce, NetSuite, and Google Shopping integrations.

Our Shopify Development Process
From requirements discovery and developer matching through design, development on a Shopify dev store, QA and UAT, launch, team training, and post-launch support — with stakeholder review at every stage.
We review your Shopify store goals, current platform (if migrating), product catalogue complexity, required integrations, Shopify vs Shopify Plus requirements, design direction, and conversion optimisation priorities. For migrations, we perform a URL and SEO audit of your existing store before the project begins. You receive a written scope document before any work starts.
Based on your project requirements — theme development, app development, Shopify Plus, or headless — we assign the right Shopify developer(s). For dedicated engagement models, you meet your assigned developer, review their Shopify portfolio, and have the option to conduct a technical interview before the engagement begins.
For custom Shopify theme projects: high-fidelity Figma mockups of all page templates (homepage, collection, product, cart, checkout, blog, and key landing pages). Shopify section and block architecture design — planning which elements are editable by your merchandising team in the theme editor without developer involvement.
Liquid theme development, app development, Shopify Plus configuration, or migration execution — all in a Shopify development store first. Weekly demo of completed work. Product data migration and redirect mapping (for platform migrations). Third-party integration development and testing. Performance testing (Lighthouse / Core Web Vitals).
Cross-device and cross-browser testing, checkout flow testing across all payment methods (including Shopify Payments, PayPal Express, Afterpay/Klarna), order notification email testing, Google Analytics 4 event tracking verification, Merchant Center product feed validation, SEO redirect verification (for migrations), and Shopify pre-launch checklist completion.
DNS/domain transfer or theme publish, Shopify Payments and shipping activation on the live store, post-launch monitoring (uptime, Shopify status page, error tracking), Google Search Console resubmission (for migrations), team training on the Shopify admin and theme editor, and a post-launch support period before transitioning to a maintenance retainer.
What Our Shopify Clients Say
Trusted by fashion brands, DTC businesses, B2B wholesalers, and eCommerce merchants in the US, UK, and Australia who rely on us for serious Shopify development work.
We migrated from a heavily customised WooCommerce store with 8,000 SKUs to Shopify Plus. 1Solutions managed the entire migration — product data, customer accounts, order history, blog content, and SEO redirects. Not a single ranking dropped in the three months post-launch. The Shopify Plus checkout customisation they built for us increased our average order value by 18%.
We needed a dedicated Shopify developer to work alongside our internal team building new features every sprint. 1Solutions matched us with a senior Liquid and App development specialist within a week. He has been with us for two years, joins our daily stand-up, and is indistinguishable from an in-house team member — at a third of the cost of a local UK developer. The quality of the code is excellent.
1Solutions built our custom Shopify app for wholesale order management — it integrates with our Salesforce CRM and SAP ERP, allows our B2B buyers to log in and place orders at their contracted prices, and syncs inventory in real time. The App Bridge integration is clean and our warehouse team adopted it within a day. Six months in, it has handled over $4M in wholesale orders without a single incident.
Why Hire Our Shopify Developers
Shopify Partner certification, 15+ years of eCommerce expertise, Shopify Plus specialist experience, custom app development capability, SEO-safe migrations, honest headless guidance, and transparent predictable monthly pricing.
15+ Years eCommerce & Shopify Experience
We have been building eCommerce stores since before Shopify existed — and have grown with the Shopify platform from its early days through Shopify 2.0, Online Store 2.0, Shopify Plus, Checkout Extensibility, and Hydrogen. Our Shopify developers hold Shopify Partner and Shopify Plus certifications.
Shopify Plus Specialists
Shopify Plus is not just a higher plan — it has a completely different feature set: Scripts, Flow, Launchpad, B2B, Markets, and Checkout UI Extensions. We have specialist experience with Shopify Plus merchants' complex pricing, multi-region, multi-currency, and wholesale requirements that standard Shopify developers rarely encounter.
Custom Code — No Theme Hack Workarounds
We write clean, maintainable Liquid and JavaScript — not CSS overrides on top of a purchased theme that break on every Dawn update. Our custom themes are built to last and to be owned and modified by your team. We document every custom section and block we build.
Migration Expertise — SEO Preserved
A Shopify migration is not a data transfer — it is an SEO project. We audit every URL, map every redirect, verify hreflang, and confirm redirect coverage before DNS cutover. We monitor Search Console for crawl errors in the weeks after migration. We have never lost significant organic traffic in a Shopify migration.
Custom App Development — Not Just Themes
Most Shopify development agencies only do themes. We build custom Shopify apps — from private merchant apps that fill gaps in the App Store, to Shopify Functions for checkout extensibility, to Checkout UI Extensions, to full public apps submitted to the App Store. App development is a core service, not an occasional side project.
Headless Shopify — When You Need It
Headless Shopify is the right choice for some merchants, and over-engineering for most. We give you an honest assessment of whether Hydrogen, Next.js Storefront API, or a well-optimised Liquid theme is the right choice for your specific performance and design requirements — and build whichever is genuinely right.
Transparent Pricing — Predictable Monthly Cost
Offshore Shopify developer costs are significantly lower than US/UK/AU agency rates. Our dedicated developer and retainer models give you a fixed monthly cost you can budget against. No hourly billing surprises. No project overruns. You know what you are spending each month.
Post-Launch Support — Not Just at Go-Live
Shopify stores need ongoing attention — new features, app conflicts, Shopify platform updates that break customisations, SEO changes, and conversion optimisation work. Our post-launch retainers give you ongoing access to your Shopify developer team without renegotiating a new project each time you need something done.
