A Shopify development agency sets up, designs and extends Shopify stores beyond what a stock theme offers: custom Liquid themes, app integrations, checkout customization, Shopify Plus features and headless storefronts. It's for brands launching on Shopify, moving from another platform, or running a store that has hit the limits of its theme and apps.
Each service below can be booked on its own or combined into a full build.
Plan selection, theme setup, navigation, collections, product import, payments (Shopify Payments, PayPal, Klarna or Mollie), shipping profiles, taxes, Shopify Markets for international selling, and only the apps you need. You get a store ready to take real orders on launch day.
Themes built from scratch or extended from Shopify's Horizon theme, using Liquid and Online Store 2.0. Your team gets sections and theme blocks to rearrange in the editor, metafields and metaobjects for content like size guides or specs, and no hard-coded text.
Like your premium theme but missing features? We add custom sections and product-page elements, and document every edit so a theme update doesn't quietly wipe out the work.
Custom apps built on the Shopify Admin API and webhooks that connect your store to an ERP, CRM, 3PL, POS or marketing platform. We also audit installed apps, a common source of slow pages and strange bugs.
Custom checkout fields, delivery rules, payment-method logic, tiered discounts and post-purchase offers built with checkout UI extensions and Shopify Functions. Shopify has been phasing out Shopify Scripts and checkout.liquid in favor of these tools; if your store relied on either, we rebuild that logic. Some checkout changes need Shopify Plus — we'll say which up front.
B2B catalogs with company accounts and price lists, multiple markets, Shopify Flow automations, expansion stores and the deepest checkout control Shopify offers. We'll also tell you plainly if Plus isn't worth it yet.
When a theme can't deliver the experience you want, we build a custom React storefront on Shopify's Storefront API — Hydrogen hosted on Oxygen, or a Next.js front end when the store lives inside a larger site. Shopify still runs products, checkout and orders.
From WooCommerce, Wix, Squarespace, Magento or BigCommerce: products, customers, blog content, order history where possible, and a full 301 redirect map so old links keep working.
Core Web Vitals fixes, app cleanup, and conversion improvements to product pages, cart and search — guided by Google Analytics 4 data and session recordings, not hunches.
Just starting with a small catalog? A well-configured premium theme may be all you need, and we'll recommend it over a custom build if it fits. If your shop is one part of a Wix site with bookings or member areas, Wix ecommerce development can be the simpler choice.
We build on Shopify, Wix Stores, WooCommerce and headless stacks, so we don't need every project to be a Shopify project. Our ecommerce website development guide compares the platforms side by side.
Product configurators, financing at checkout and live data lookups are part of our recent ecommerce work — the kind of features that decide whether a store wins or loses the sale.
Anything a marketer might change is exposed in the theme editor. Code is versioned in GitHub, and we work on a duplicate theme so your live store is never a test bench.
Wix Engine has been building websites and online stores since 2014 for clients in 15+ countries, with a Top Rated record on Upwork.
What you sell and where, your current platform, must-have features and launch date.
For live stores, a review of theme, apps and speed; for new ones, a feature plan, app list, timeline and fixed price.
Home, collection, product and cart templates designed in Figma by our UI/UX design team and approved before any code is written.
Theme code, apps, integrations and data import, with a preview link you can click through at any time.
Every payment method, discount, shipping zone and notification email tested on real phones and desktops.
Domain connection, redirects and analytics checks, then optional monthly support for new features and conversion work.
Our two most recent ecommerce builds are custom Next.js stores. Purely Solutions has product configurators, financing at checkout and a live postal-code water-quality lookup. AGOBAY combines an artisan shop with an editorial magazine and event bookings.
The same team builds on Shopify: Liquid themes for stores that live in the theme editor, Shopify Functions and checkout extensions for custom rules, and the Storefront API when a store needs a custom Next.js front end.
Shopify projects with us start from $800 for a store setup on an existing theme. Custom themes, Plus features, integrations and headless builds are quoted after a call.
What affects the price:
Your Shopify plan, paid theme and app subscriptions are billed directly by Shopify and the app developers. Choose a fixed-price project, a monthly retainer, or hourly work at $45/hour (minimum 40-hour block). Want a developer working inside your team? Hire a Shopify developer hourly or on a dedicated basis.
Send your requirements and you'll get an exact estimate within 48 hours.
At Wix Engine, Shopify projects start from $800 for a store setup on an existing theme. Custom theme development, Shopify Plus work, integrations and headless storefronts are priced by scope after a free call. Shopify's plan fees and app subscriptions are separate. You'll get an exact estimate within 48 hours of sending your requirements.
A typical store takes 3–6 weeks, depending on how soon product data and content are ready. Custom themes, headless storefronts and heavily integrated builds take longer. The timeline is set in your proposal, and you get progress updates every week.
A premium theme is enough for many stores, especially at launch. Custom theme development makes sense when your product needs layouts no theme offers, when you've stacked apps to fill gaps, or when your brand must stand apart from competitors on the same theme. We'll recommend the cheaper route whenever it fits.
Shopify Plus is worth it when you need what it uniquely offers: the deepest checkout customization, B2B selling at scale, expansion stores, or higher API limits for heavy integrations. Many growing brands are well served by Shopify's Advanced plan. We compare your requirements against each plan before you commit to an upgrade.
Hydrogen is Shopify's React framework for building custom storefronts that connect to Shopify through the Storefront API, usually hosted on Shopify's Oxygen platform. It gives you full design freedom and very fast pages, but costs more to build and maintain than a theme. Most stores should start with a theme and go headless when they outgrow it.
Yes. We migrate products, variants, customers, blog posts and order history where possible, keep page titles and meta descriptions, and set up 301 redirects from every old URL to its Shopify equivalent. Rankings can't be guaranteed during any move, but a careful redirect map is the best protection for traffic you've already earned.
Yes. We build themes so your team can change text, images, banners, collections and page layouts in Shopify's theme editor without code. You'll get a walkthrough at handover, and we're available for bigger jobs like new features or seasonal campaigns.
Usually, yes. The most common causes are apps loading scripts on every page, oversized images and heavy theme code. We audit the store, remove or replace what's slowing it down, and measure Core Web Vitals before and after so you can see the difference.
