A Shopify development company for stores that have outgrown quick fixes.
Shopify stores stall in familiar ways: a theme patched by three different freelancers, a dozen apps loading scripts on every page, discount logic still written for Shopify Scripts, and an ERP sync someone runs by hand each morning. Brands call us when the next fix has to be engineered rather than installed. Our Shopify developers rebuild what is slowing the store down and build what the app store cannot, from Shopify app development services to Shopify integration services for your ERP and 3PL. When the goal is the full platform jump, our Shopify Plus agency team carries it end to end, and our Shopify migration services move you over from Magento, WooCommerce, or BigCommerce.
Shopify development services, from custom themes to headless storefronts.
Nine kinds of Shopify work, handled by the same senior developers. Most projects combine two or three of them, so we scope against your store and roadmap rather than a package.
What changed on Shopify, and what it means for your next build.
Shopify has rebuilt how checkouts, discounts, themes, apps, and tracking are customized. A store built a few years ago can look fine and still depend on code Shopify no longer runs. These are the changes our Shopify developers plan every build around.
Checkout extensibility replaced checkout.liquid
Checkout changes now run as checkout UI extensions, Shopify Functions, and branding settings that Shopify keeps working through its own updates. We rebuild old checkout code on these surfaces, step by step.
Shopify Functions replaced Shopify Scripts
Discount, shipping, and payment rules are now Functions: small programs compiled to WebAssembly that run inside Shopify under strict resource limits. We port Scripts logic to Functions and test it against real carts.
Online Store 2.0 and theme app extensions
JSON templates, sections on every page, and app blocks let your team edit layouts in the theme editor, and let apps add features without editing theme files that the next app update will overwrite.
Metafields and metaobjects for structured content
Size charts, spec tables, ingredient lists, and store locations belong in metaobjects instead of hard-coded HTML, so your team can edit them once and the theme can reuse them anywhere.
The GraphQL Admin API is the main API
Shopify treats the REST Admin API as legacy. The apps and integrations we build use GraphQL and bulk operations, which also cope far better with large catalogs and order histories.
Tracking moved to customer events
Pixels can no longer be pasted into checkout. Analytics and ad tracking run through customer events and web pixels, so we set them up there and confirm purchases report correctly before launch.

Shopify or Shopify Plus: buy the plan the work needs.
Most development is the same on every plan: themes, apps, Hydrogen, and integrations. Plus changes what you can do in the checkout and how far the store can scale. We build to the same standard on either and recommend Plus only when the work requires it.
On standard plans we build custom Online Store 2.0 themes, custom apps, Hydrogen storefronts, and integrations. The checkout runs on Shopify's standard settings, which suits most stores, and the thank you and order status pages can still be extended.
- Your checkout works as Shopify ships it
- The custom work lives in the theme, apps, and integrations
- You sell from one store, in one or a few markets
On Plus we customize the checkout itself with checkout UI extensions and custom Shopify Functions, schedule big launches with Launchpad, open expansion stores for new regions or brands, and run heavier integrations on higher API limits.
- The checkout needs custom fields, validation, or logic
- Launches need scheduled theme, price, and product changes
- You run several stores or high order volume

A wholesale build and a DTC build on Shopify, in detail.
A wholesale replatform onto Shopify Plus that we are building now, and a direct-to-consumer brand we built and grew on Shopify. Both case studies show the full scope.
Europa Eyewear supplies 5,300+ independent eyecare accounts and owns brands including American Optical and EyeBobs. We are rebuilding its wholesale storefront on Shopify Plus, replacing an unsupported custom portal where orders went in one SKU at a time and invoices were mailed by hand.
- SparkLayer matrix ordering and quick reorder across frame, color, and size
- Buying-group price lists, Net 30/60 terms, POs, and approvals on Shopify B2B
- Self-service order history and invoices for every account
- Commercient SYNC to the SouthWare ERP, and Mirakl marketplace feeds for Nordstrom and Bloomingdale's
- 3,500+ products moving onto a Dawn-derived custom theme
Runners Athletics is an Austin activewear and accessories brand. We built its store on Shopify, mobile-first, then ran the marketing around it: content, photoshoots, paid ads, and email.
- A mobile-first theme with image swatches and improved site search
- Quick add-to-cart on every collection page
- 3D product images and 360-degree product views
- A shorter checkout with Apple Pay, Google Pay, Amazon Pay, and buy now, pay later
- Checkout upsells for complementary products
Taking over a Shopify store: what our Shopify developers check first.
Many clients come to us with a store someone else built. Before we quote any change, we review six things, because they decide whether a fix is a day of work or a rebuild.
The app stack
Every installed app, what it injects into the storefront, which apps duplicate each other, and the code that uninstalled apps left behind in the theme.
The theme
Whether it is an Online Store 2.0 theme or a vintage one, how heavily it was edited, and whether a rebuild would cost less than another round of patches.
Speed on real pages
Core Web Vitals on your top product and collection pages, measured on mobile, with each slow script traced back to the app or snippet that loads it.
Checkout and discounts
What still depends on old checkout code or Scripts, how discounts stack, and whether the checkout needs Plus features or can stay on your current plan.
Data and integrations
How orders, inventory, and prices move between Shopify and your ERP, 3PL, or PIM, and where staff still copy data by hand.
Tracking
Which pixels fire through customer events, which ones double-count, and whether revenue in your analytics matches Shopify's own reports.
A Shopify development partner whose job is to get you promoted.
You're going to love coming to work. Think of us as an extension of your team, here whenever you need us. Our mission is simple: your store wins, and so do you.
Why brands choose IWD for Shopify development that lasts.
Shopify makes it easy to launch and easy to pile on apps. The stores that keep growing are the ones built on the platform's current surfaces, with a short app list and code someone can read. That is the store we build.
Shopify Plus partner depth
We build on the parts of Shopify that changed most: checkout extensibility, Functions, theme app extensions, and the GraphQL Admin API. Code written to those surfaces keeps working as Shopify ships updates.
Senior Shopify developers on every ticket
The developer who audits your theme and app stack is the one who fixes it. There is no junior bench learning on your store.
Fewer apps, not more
Many slow Shopify stores run apps that overlap or leave code behind. We cut the stack to the apps that earn their keep and build the rest into the theme or a custom app.
We stay after launch
We keep 94% of clients after launch. The developers who built your store keep improving it, so nobody has to relearn your theme, apps, or integrations.
We know the platform you are leaving
We also build on Magento, Adobe Commerce, and BigCommerce. When we recommend Shopify it is because it fits, and when we migrate you onto it we know the old system's data and quirks.
How a Shopify project runs, from audit to launch and beyond.
Audit
We review the theme code, every app and the scripts it adds, Core Web Vitals on real pages, your integrations, and how tracking events fire.
Plan
A phased roadmap that says what to rebuild, which apps to drop, and whether you need Plus or Hydrogen, with scope, timeline, and a firm number.
Build
Work happens on a duplicate theme or a development store, with theme code in Git, code review on every change, and weekly demos.
Launch and grow
We publish without downtime, watch checkout and conversion data after launch, and keep shipping from the backlog with the same developers.
What merchants ask before they hire our Shopify developers.
Do you work on Shopify, Shopify Plus, or both?
Both. Most theme, app, headless, and integration work is the same on any plan. Plus matters when you need to customize the checkout itself, open expansion stores for new regions or brands, or push higher API volume. We tell you whether the work you have in mind actually needs Plus before you pay for it.
Can you take over a Shopify store another agency or freelancer built?
Yes, and it is one of the most common ways clients start with us. We audit the app stack, the theme, speed on real pages, checkout customizations, integrations, and tracking, then give you a plain-language report and a prioritized plan before we change anything.
Should we build headless on Hydrogen or stay on a Liquid theme?
Most stores should stay on a well-built Online Store 2.0 theme: it is faster to ship, cheaper to run, and your team can edit it in the theme editor. Hydrogen makes sense when the storefront is a product in its own right, with custom content models, heavy personalization, or several storefronts on one back end, and you have the budget to maintain a React app.
What happened to checkout.liquid and Shopify Scripts?
Shopify retired checkout.liquid and replaced Shopify Scripts with Shopify Functions. Checkout changes now use checkout UI extensions, Functions for discount, shipping, and payment logic, and checkout branding. If your store still relies on old checkout code or Scripts, we map each customization to its replacement and rebuild it.
How do you scope and quote a Shopify project?
We scope from the store itself: the theme, the app stack, the integrations, how many markets and languages you sell in, and whether Plus features are needed. You get a firm, itemized quote on the first call, so you know what you are committing to before work begins.
Can we hire your Shopify developers as an embedded team?
Yes. Senior Shopify developers can join your sprints and code reviews and work in your repository and theme workflow as part of your team. Fixed-scope projects and monthly retainers are available too.
Can you migrate our store to Shopify from Magento, WooCommerce, or BigCommerce?
Yes. We map products, variants, customers, and order history, set up 301 redirects for every old URL with traffic or links, and rebuild custom features as theme code or a custom app, so the move protects your search rankings.
Do you handle B2B and selling in several countries?
Yes. We set up Shopify B2B with company profiles, catalogs, and payment terms, add apps such as SparkLayer when buyers need matrix ordering, and configure Shopify Markets for currencies, languages, and regional catalogs.
