What do we do?

Pain points we solve

Is Your Shopify Development Costing You Customers Every Day?

Most businesses lose customers every day to Shopify development that does not perform. If any of these sound familiar, you are losing revenue right now:

• Bloated themes from Themeforest dragging Core Web Vitals
• 30+ apps stacking subscription costs
• Generic checkout converting below industry average
• Inability to customise checkout beyond Plus tier
• Inventory disconnected from ERP and WMS
• Slow product pages killing paid-ad ROAS

Every one of these is solvable. Most are solvable inside the first 8 weeks of the right engagement.

FAQ

Do you have any questions?

Frequently Asked Questions

Shopify vs Shopify Plus — when to upgrade?

Around USD 1–2M annual revenue, when you need checkout customisation, dedicated support and lower transaction fees.

Can Shopify handle B2B?

Yes via Shopify Plus B2B. Strong for catalogue/account/quote workflows; less mature than Magento for complex pricing rules.

Should we go headless with Hydrogen?

Worth it for design-led brands and content-heavy storefronts. Overkill for standard DTC under USD 5M GMV.

Can you optimise our existing Shopify store?

Yes. Theme audit, app stack pruning (typically cuts 30–60% of monthly app spend), image optimisation, Lighthouse tuning.

Do you build custom Shopify apps?

Yes — both public apps for the App Store and private apps for specific client integrations.

How long does a Shopify build take?

Small DTC: 4–8 weeks. Mid-size with custom theme: 8–14 weeks. Plus migrations or Hydrogen: 12–22 weeks.

Insights

Custom Shopify Website Development Services for Growing Businesses

Custom Shopify website development services are the highest-volume engagement type in ecommerce in 2026 — and for good reason. Shopify and Shopify Plus dominate the DTC market because the platform handles the most painful parts of running an online store (hosting, security, PCI compliance, app ecosystem, predictable performance) better than any competitor. We build, optimise and migrate Shopify stores for DTC fashion brands, supplement companies, beauty retailers, consumer electronics, and increasingly B2B sellers on Shopify Plus B2B. Every Shopify engagement starts with a 90-minute audit covering theme code quality, app stack costs, catalogue structure, checkout funnel and performance metrics. From there we recommend the right path: a fresh custom theme build, an existing theme rebuild, an app stack prune, a Plus migration, or a Hydrogen headless storefront. We are fluent in Liquid, Shopify Functions, the Shopify CLI, Hydrogen + Oxygen, Shopify Markets for international, and Shopify Plus B2B. Every store we ship targets Lighthouse 90+ mobile, full Product/Offer/Review schema, Core Web Vitals pass, and a checkout funnel optimised against industry-leading conversion benchmarks. We also handle migrations from WooCommerce, Magento and Wix to Shopify with full SEO redirect mapping, customer/order/product data carry-over, and minimal launch downtime.
