Build Smarter on Shopify with Single Grain's Shopify Development Approach

We design, build, and optimize Shopify and Shopify Plus stores that convert—custom themes, apps, integrations, and CRO. As a Shopify development agency, we ship clean code, measurable growth, and reliable performance.

Why Your Brand Needs a Smarter Shopify Stack

Shopify powers millions of stores, but sustainable growth takes more than a theme swap and a few plugins.

At Single Grain, we align your storefront, data, and operations across the pillars that matter:

Storefront & UX

OS 2.0 themes, headless storefronts, PWAs, accessible design

Integrations & Data

ERP, CRM, 3PL, subscriptions, payments, tax and shipping

Performance & Security

Speed, Core Web Vitals, edge caching, PCI-conscious workflows

Analytics & Growth

CRO, SEO for ecommerce, AOV/LTV tracking, attribution

Let's Talk

How We Build and Scale on Shopify

We don't just install a theme and call it a day. Our team engineers a Shopify stack that drives conversions, streamlines operations, and sets you up for long-term growth.

Plan Your Architecture

We audit your current stack, map data flows, and define KPIs. Then we recommend the right path—Shopify or Shopify Plus, headless vs. theme, and a vetted app ecosystem.

Design and Develop the Storefront

We craft UX that removes friction and builds trust. From OS 2.0 sections to custom components, we ship fast, accessible, and maintainable code.

Get Started

Connect and Automate Your Systems

We integrate ERP/CRM/OMS, subscriptions, and fulfillment. Using APIs, webhooks, and Flow, we automate key workflows to reduce manual work and errors.

Migrate, Launch, and Optimize

We manage data migration, SEO-safe redirects, QA, and staging. Post-launch, we A/B test templates, improve checkout, and refine merchandising.

Measure and Keep Improving

We set up dashboards for conversion rate, AOV, and LTV. Each month, we prioritize a backlog of enhancements and ship high-impact sprints.
