Custom Shopify Themes & Apps

Shopify Plus Development at Scale

We've been building on Shopify since before Shopify Plus existed, and we've watched the platform evolve from a simple storefront builder to a legitimate enterprise commerce platform. Our Shopify work spans custom theme development, app engineering, and the full spectrum of platform customization.

Our clients have collectively processed over $50M in GMV on Shopify Plus storefronts we've built. We know where the platform excels, where it needs custom work, and where to draw the line.

Custom Theme Development

A Shopify theme is more than a design layer — it's a performance-critical customer experience that directly affects conversion.

Our theme builds start with:

• Performance budgets: We target sub-2s LCP on mobile before design decisions are made
• Design systems: Component-based Liquid architecture that's maintainable post-handoff
• CRO principles: Section/block architecture with inline A/B testing hooks
• Accessibility: WCAG 2.1 AA compliance across all components

We build on Dawn as a foundation when budgets allow, or from scratch when brand requirements demand it. Hydrogen builds are available for brands needing edge-rendered performance.

Custom App Development

Shopify's app ecosystem covers most common needs, but every brand eventually hits requirements that off-the-shelf apps can't address. We build private and public apps for:

• Back-office integrations: Sync inventory, orders, and customers between Shopify and your ERP/WMS/3PL
• Checkout customization: Beyond what Shopify's native UI allows — custom payment flows, B2B pricing, subscription handling
• Merchandising tools: Internal apps that give your team control over complex catalog operations
• Analytics and reporting: Custom dashboards surfacing data across your Shopify ecosystem

Apps are built with Node.js, the Shopify API libraries, and Polaris for internal tool UIs. We use Shopify's managed OAuth and session handling — no reinventing authentication.

Checkout Extensibility

Shopify's Checkout Extensibility (available on Plus) allows custom UI injection at every checkout step. We use this for:

• Upsell and cross-sell recommendations at cart and checkout
• Custom loyalty and rewards displays
• B2B-specific fields and pricing presentations
• Shipping and delivery date selection
• Post-purchase pages with AI-driven product recommendations

Checkout extensions communicate with your backend APIs in real time, enabling dynamic personalization without Shopify's native UI constraints.
