Shopify development
3 Horizons Interactive designs and builds Shopify stores for consumer product brands. We offer a range of development services extending from theme development and custom section work to Checkout Extensibility (i.e. checkout customization) and post-launch optimization.
What's included
3Hi handles the full scope of a Shopify build: theme development, custom sections, app integrations, and the tracking setup that makes your data usable after launch.
Every build starts with a proven, premium theme rather than a blank canvas. We customize the theme's Liquid code and build custom sections to match your brand and the features your business needs.
We handle collections, navigation, and page structure, and migrate your existing content and products so nothing gets lost in the move.
We build on Shopify Plus for merchants who need it, including Checkout Extensibility (checkout customization).
We migrate stores from WooCommerce, Magento, BigCommerce, Wix, and WordPress.
We set up GA4, server-side tracking, and Conversions API, and connect the apps your store depends on (email, reviews, subscriptions) so your data is accurate from day one.
Every build includes two weeks of monitoring after launch, with the option to move into an ongoing retainer.
Our work
Case study
Kodo Kids came to us with a site that no longer reflected their brand or supported their mix of B2B institutional buyers and B2C retail customers. We rebuilt the site on a new Shopify theme, redesigned the homepage and product pages around storytelling and conversion, added B2B quote-request and customer segmentation tools, and cleaned up a catalog of more than 3,400 SKUs. Since launch, Kodo Kids has seen a 49% increase in conversion rate.
49% Increase in conversion rate since launch
“A few months ago, I posted looking for support rebuilding and re-theming our Shopify website. I had mapped a myriad of improvements to optimize the site, but I'll be the first to admit, I'm not a web expert. My friend Hannah Howard came to the rescue and connected me with Peter Kalanda. From there, Peter introduced me to Alan Tabor, and the magic really started to happen. Peter and Alan have been instrumental in transforming our site, including a 49% increase in conversion rate since our March launch. And we're just getting started.”

Timeline
Most builds run 2.5 to 4 weeks, depending on scope. Larger projects take longer, and we'll flag that during the first phase rather than let it surprise you later.
After launch
At the end of every build, we hand everything over and teach your team to run the store, or we stay on as part of your team and manage it for you. When you're ready to grow, our AI visibility plans measure how often ChatGPT, Gemini and other assistants recommend your products, and raise those odds.
AI visibility for Shopify brandsFAQ
Shopify Plus is Shopify's enterprise plan, built for higher-volume merchants. It adds features like Checkout Extensibility (checkout customization), higher API limits, and dedicated support, and the license is billed directly by Shopify. We build on both, depending on what your business needs.
Both. We build new stores and work on existing ones: re-theming, custom Liquid sections, new features and Checkout Extensibility. On an existing store we look for the root cause of what isn't working first, so the fix holds.
Yes. We migrate stores from WooCommerce, Magento, BigCommerce, Wix and WordPress, and move your existing content and products so nothing gets lost in the move.
Yes. Every build includes two weeks of monitoring after launch. After that, the choice is yours: we turn everything over and teach your team how to manage the store, or we stay on as part of your team on an ongoing retainer.
Every build is set up so search engines and AI assistants can read your store: a clean page structure, accurate product data and structured markup. For ongoing visibility, our AI visibility plans for Shopify brands measure how often ChatGPT, Gemini and other assistants recommend your products, and raise those odds.
You do. The store lives in your own Shopify account, and the theme and custom code we build for you are yours. At the end of every project we turn everything over and teach your team how to manage it.
A short discovery call, collaborator access to your Shopify store (or your current platform if you're migrating), your brand assets and your product data. If content and photography aren't ready, we can create them; that's one of the things that moves the price.
We focus on consumer product brands, including baby and kids products and direct-to-consumer ecommerce. If you're not sure you're a fit, book a consultation and we'll tell you straight.
