What we build

Shopify development services

Most Shopify projects start in one of three places: improving an existing theme, building a custom storefront or connecting the systems your business runs on. We recommend the approach that fits your requirements and maintenance budget. If the store needs designing first, our UI/UX and brand design team can shape it before development.

See our Shopify work: a custom Liquid theme for Rehall, subscriptions for Ovabalance and a 9,400-product, three-language store for Kampeerwinkel Roermond.

Headless Shopify storefronts in React and Next.js

A separate frontend connected to Shopify can support custom journeys, editorial content and multiple sales channels. We weigh the benefits, integration work and ongoing maintenance against a standard Shopify theme before recommending headless.

  • Next.js and React storefronts
  • Shopify Storefront API
  • Sanity or Contentful CMS integration
  • Performance planning and testing

Custom Shopify theme development in Liquid

We build and extend Shopify themes in Liquid, CSS and JavaScript, using Online Store 2.0 sections, metafields and metaobjects. The result fits your brand and lets your team update content without rebuilding pages.

  • Online Store 2.0 themes
  • Figma designs built in Liquid
  • Custom metafields and metaobjects
  • Accessibility and keyboard checks

Shopify ERP, app and API integrations

Connect Shopify with your ERP, PIM, CRM or warehouse system so product, inventory and order data stay in sync. We review API access, data ownership, sync rules and failure handling before quoting an integration.

  • ERP and inventory sync scoping
  • Custom Shopify apps and APIs
  • Shopify Flow automation
  • B2B wholesale portal architecture

Shopify Plus & B2B

Shopify Plus, B2B and international selling

A Shopify store that scales needs clear product information, reliable integrations and an editing workflow your team understands. We plan the theme, apps and data flows together, then test the agreed customer journeys before launch.

What you can build depends on your Shopify plan. We scope checkout extensions, Shopify Markets and B2B selling, and explain platform, app and development costs up front. Live example: Kampeerwinkel Roermond sells 9,400+ products in Dutch, English and German, with iDEAL, Klarna and KBC/CBC at checkout. Need a portal or tool beyond Shopify? See our custom web development service.

  • B2B & wholesale on Shopify

    Plan company accounts, customer-specific catalogues, price lists and payment terms around the B2B features available on your Shopify plan.

  • Checkout extensibility

    Scope checkout branding, UI extensions and Shopify Functions where your plan supports them, then test each supported checkout journey.

  • Shopify Markets & localisation

    Set up markets, currencies, languages and domains for the Netherlands, Germany, the UK, the US and beyond, with payment methods that suit each market.

Shopify questions, answered

Straight answers to common questions about Shopify and Shopify Plus development, custom themes, migrations, integrations and cost.

Is Shopify Plus worth it, or is standard Shopify enough?

It depends on the features you need rather than revenue alone. Shopify Plus adds deeper checkout customisation, advanced B2B capabilities and options for running several stores, while many B2B and international selling features are also available on other plans. We compare your requirements, apps and operating costs against each plan before recommending an upgrade.

Will we lose SEO rankings when migrating to Shopify?

A carefully planned migration keeps the risk low, but rankings can still fluctuate and cannot be guaranteed. We map every important URL, set up 301 redirects, carry over titles and meta descriptions, and scope products, customers and orders separately because each platform has different export limits. After launch we check redirects, crawl errors and tracking.

Do you build headless Shopify stores?

Yes, when it suits the project. We can scope a React or Next.js storefront connected to Shopify's Storefront API, with a headless CMS such as Sanity or Contentful. Headless adds development and maintenance work, so we first check whether your customer journeys and content requirements need it or whether a custom Liquid theme will do the job.

Can you integrate our ERP or CRM with Shopify?

Usually, yes, depending on the systems involved. We review your ERP or CRM, its API documentation, permissions and data flows before confirming feasibility and scope. A good integration plan defines which system is the source of truth, how often data syncs, how errors are handled and any third-party licence or connector costs.

Do you offer Shopify support after launch?

Yes. Ongoing Shopify support can include theme maintenance, app and integration reviews, performance checks and prioritised feature improvements. We agree the scope and reporting cadence with you separately. Revenue improvements depend on traffic, your offer and customer behaviour as well as the website, so we focus on measurable fixes rather than promised results.

How much does Shopify development cost?

It depends on scope: theme customisation, a custom Liquid theme, a headless storefront, integrations and data migration each involve very different effort. Your Shopify plan and paid apps are separate ongoing costs. We quote after reviewing your requirements and explain development, platform and app costs before work starts. Our pricing page shows starting prices for typical projects.

Should we use a custom Shopify theme or a premium theme?

A premium theme is a fast, cost-effective start when its layouts fit your catalogue. A custom Liquid theme makes sense when you need specific templates, metafield-driven content or leaner code than a multipurpose theme provides. We compare both before you commit. Our article on custom Liquid vs premium Shopify themes covers the trade-offs.
