Shopify Development Services
Launch Faster, Merchandise Smarter, Scale Without a Replatform
Shopify's advantage is what it takes off your plate. Hosting, PCI compliance, checkout security, and platform updates are handled, which means the engineering budget goes into the things customers actually see — product pages, merchandising, and the path to checkout.
The trade-off is that Shopify has opinions. Working well on it means knowing where the platform gives you room and where fighting it is expensive. That's most of what we bring.
Custom Shopify Development
Themes from the marketplace get you live. They rarely get you differentiated, and they almost never handle a catalog with unusual structure.
Our custom Shopify development work covers:
- Custom theme development built from a clean base rather than a heavily modified marketplace theme
- Product page architecture for variants, bundles, subscriptions, and configurable products
- Collection logic, filtering, and navigation for large or seasonal catalogs
- Shopify API and third-party integrations — ERP, 3PL, CRM, and inventory systems
- Custom apps where an off-the-shelf app doesn’t fit the requirement
- Check out extensibility and Shopify Plus features including Shopify Functions and B2B
We build with maintainability in mind. A store held together by fourteen apps and a pile of theme edits becomes a rebuild in two years, and we’d rather not sell you that twice.
Shopify Theme Development and Design
Your theme is your merchandising system, not decoration. We build Shopify theme development projects around how customers actually move: what they need to see on a product page before adding to cart, how quickly a mobile shopper can reach checkout, and where hesitation is costing orders.
Every build includes a mobile-first layout, page speed optimization against Core Web Vitals, accessible markup, and a structure your team can update through the theme editor without calling us for every change.
Shopify Store Development and Migration
We handle Shopify store development for new brands and migrations for businesses moving from WooCommerce, Magento, BigCommerce, or a custom system.
Migration is where most agencies quietly lose client traffic. We plan the URL structure and redirect map before touching anything, migrate products, customers, and order history with reconciliation checks, and verify search visibility after cutover rather than assuming it survived.
Our launch process covers catalog and product data setup, payment and shipping configuration, tax rules, staged testing, and a monitored go-live.
Shopify Maintenance Services
A store isn’t finished at launch. Apps update, themes drift, and conversion rates decay quietly.
Our Shopify maintenance services include theme and app updates with staging tests, performance monitoring and speed work, bug fixes, security and checkout monitoring, seasonal merchandising support, and a monthly review of conversion and revenue per visitor.
You get a named contact and a response window.
Agile, Collaborative Team
Centaur operates as an extension of your team, bringing senior-level strategy and hands-on execution without the overhead of a large agency.
Proven Scale
With over 25 years of experience and support for more than 1,600 business launches, Centaur brings a depth of real-world knowledge rarely found in a boutique agency.
Store Builds That Are Ready to Sell
We don't hand over a store and walk away. Our e-commerce, marketing, analytics, and packaging design teams sit together, so the store's product photography, ad landing pages, and unboxing experience are built as one system.
Why brands work with us on Shopify:
- Custom builds instead of modified marketplace themes
- Migrations planned around search visibility, not just data transfer
- Integrations with the systems you already run
- Conversion work informed by your analytics, not general best practice
- Ongoing maintenance with defined response times
- One team across store, marketing, analytics, and design

Frequently Asked Questions
Shopify development services cover custom theme development, store setup and configuration, app and API integrations, migrations from other platforms, checkout and conversion optimization, and ongoing maintenance after launch.
A marketplace theme is reasonable for a small catalog and a fast launch. Custom Shopify development makes sense when you have complex product variants, a distinctive brand, unusual merchandising needs, or a store you plan to scale—because heavily modified marketplace themes get expensive to maintain.
Yes, with planning. We map the existing URL structure to the new one and implement 301 redirects before launch, migrate product, customer, and order data with reconciliation checks, and monitor indexation and rankings after cutover. Some short-term fluctuation is normal; sustained loss usually means the redirect map was skipped.
Yes. We build on Shopify Plus where the requirement calls for it—checkout customization through Shopify Functions, B2B catalogs and price lists, higher API limits, or multi-store setups. We’ll also tell you when Plus isn’t worth the cost for your volume.
Theme and app updates are tested on staging before deployment, performance and speed monitoring, bug fixes, security and checkout monitoring, seasonal merchandising support, and a monthly conversion review.
