From our own work: We built Velocity, a premium e-commerce storefront concept with product-first merchandising and a frictionless cart flow. Read the Velocity case study.
Custom themes, not off-the-shelf compromises
A purchased theme gets you live fast, but every brand ends up fighting its limitations. We build custom Shopify themes and Online Store 2.0 sections that your team can rearrange without a developer, and that load quickly on mobile.
Apps, integrations and Shopify Plus
We build custom Shopify apps and checkout extensions when the App Store doesn't cover your workflow, and connect Shopify to ERPs, 3PLs, marketplaces and accounting tools. For high-volume brands we handle Shopify Plus features, B2B wholesale and headless storefronts with Hydrogen.
What's included
- Custom Shopify theme development
- Shopify Plus and headless (Hydrogen) storefronts
- Custom apps and checkout extensions
- ERP, inventory and 3PL integrations
- Migration from WooCommerce, Magento or BigCommerce
What it means for your business
Built to scale
Architecture chosen for where you'll be in three years, not just launch day.
You own everything
Code, repositories and infrastructure accounts are yours from day one.
Fixed scope, fixed price
A strategy call defines the scope; the quote doesn't move mid-project.
How we work
Discover
A short call to understand your business, customers and goals — then a fixed quote.
Design
We design around your brand and your customers, and you approve before we build.
Build & integrate
We develop, connect your tools and test on real devices.
Launch & grow
We go live, then keep improving through a monthly partnership — SEO, CRO, automation and AI.
Frequently asked questions
Do you work with existing Shopify stores?
Yes. We take over existing stores, audit theme and app performance, and improve speed, conversion and integrations without a full rebuild where one isn't needed.
Can you move us to Shopify from another platform?
Yes — WooCommerce, Magento, BigCommerce and Squarespace migrations include products, customers, orders and SEO redirects.
How much does it cost?
Every Shopify Development project is different, so we don't publish a price list. Answer a few questions in our quote builder and you'll get a personalised plan and estimate — compared with market prices and designed around your budget — in about 3 minutes.
Do I own what you build?
Yes. The code, content, accounts and data are yours. No lock-in — leave any time and we'll help you move.
