Shopify Stores Built to Convert

Custom Shopify themes, app development, and checkout optimization for merchants who want more than a template.

Shopify is a powerful platform. Most stores barely scratch the surface of what it can do. The default themes are designed to be generic enough for everyone, which means they're optimized for no one. We build Shopify stores that are specific: specific to your products, your brand, and the way your customers actually shop. Custom theme code, a conversion-focused layout, and an experience that holds up from homepage to confirmation email.

Custom Liquid themes

Built for your brand

Conversion-first

Checkout to homepage

App Store + custom

Extended where needed

Custom Shopify themes from scratch

We write Liquid from the ground up rather than customizing a marketplace theme until it barely resembles the original. That gives you a clean codebase, a store that loads fast, and a design that's as distinct as your brand — not a familiar layout with your logo dropped in.

Every section, every block, every template is purpose-built. Product pages are structured around your specific products. Collection pages are laid out for how customers browse your catalog. The checkout carries your brand through to the end.

Checkout and conversion done right

Checkout is where revenue is won or lost. Shopify's native checkout is solid, but it can be extended and shaped — cleaner layouts, upsell touchpoints, a post-purchase flow that captures more without friction. We treat checkout as a designed experience, not a system page.

Conversion optimization runs through the whole store: clear hierarchy on product pages, well-placed social proof, a cart experience that reduces abandonment, and a mobile flow that actually works. Small improvements compound across thousands of sessions.

  • Shopify Checkout extensions and customization
  • Cart drawer and abandonment recovery
  • Post-purchase upsells and thank-you flows
  • Product page A/B testing setup

Custom Shopify apps and integrations

When the Shopify App Store doesn't have exactly what you need — or you'd rather own the feature than pay a monthly subscription forever — we build it. Custom Shopify apps for loyalty programs, subscription flows, custom pricing rules, B2B portals, or any functionality your store requires.

We also connect your store to the systems around it: ERP, inventory management, fulfillment, email platforms, loyalty providers, wholesale portals. Clean API integrations that keep data in sync and remove manual work from your operations team.

  • Custom Shopify app development
  • Third-party API and webhook integrations
  • B2B and wholesale portal builds
  • Subscription and recurring billing

Speed, SEO, and long-term maintainability

A fast store ranks better and converts better. We optimize every Shopify build for Core Web Vitals: deferred scripts, properly sized images, minimal render-blocking resources, and a clean Liquid architecture that doesn't hammer the server on every page load.

We also structure your theme code so it's maintainable. Shopify is a managed platform, but themes still need updates, new sections, and seasonal changes. Clean, documented code means those changes are quick and don't introduce regressions.

What this looks like

Things we build in this space

Fashion and Apparel Store

A custom Shopify theme with a full-bleed editorial homepage, a collection page built around visual browsing, and a product page with integrated size guide and social proof sections.

Health and Wellness Brand

A subscription-first store built on Shopify with a custom subscription app, a tiered loyalty program, and a post-purchase flow that drove meaningful repeat purchase rates.

B2B Wholesale Portal

A Shopify store with a custom B2B portal layered on top: wholesale pricing, volume discounts, a quote request flow, and an account portal for buyers to manage their orders.

FAQ

Common questions

Can you migrate an existing store to Shopify?
Yes. We handle full platform migrations — products, customers, orders, and SEO redirects — from WooCommerce, Magento, BigCommerce, or any platform with accessible data. We plan the migration carefully to protect your organic traffic and your order history.
Do you work with Shopify Plus merchants?
Yes. Shopify Plus unlocks checkout extensibility, more script customization, B2B features, and dedicated infrastructure — we're comfortable in the full Plus environment and have experience building for merchants at that scale.
What about the Shopify apps we already pay for — do you replace them?
Not necessarily. Some apps are well-built and earn their monthly cost; no reason to rebuild what works. We audit what you have, identify apps that could be replaced with lighter custom code or a better-fit solution, and only recommend changes that have a real payoff.
