Shopify Plus Store Development

Shopify Plus store development, built by the people you talk to

Saints & Sparrows builds Shopify and Shopify Plus stores for brands that have outgrown a template but don't want an agency that hands the work to juniors. The senior people who scope your build are the people who build it. Most storefront builds run 6–10 weeks, and everything we create (theme, apps and data) is set up in your name from day one.

Customize a theme or build a custom one?

It depends on how far your store is from what a good theme already does. A premium theme, customized well, is the right call for most brands: it's faster to launch, cheaper to maintain, and it keeps up with Shopify's updates. A custom theme earns its cost when your catalog, merchandising, or buying journey really doesn't fit a standard layout. That could be a fitment-driven parts store, a configurator, or a heavy B2B and DTC mix. We'll tell you which side you're on before you spend anything. Headless builds are on the table too, but only when the payoff is clear, because they add cost and ongoing engineering.

What makes a Shopify Plus build different

Plus gives you tools a standard plan doesn't: checkout extensibility, native B2B with company pricing and payment terms, expansion stores for international or sister brands, and higher API limits for large catalogs and integrations. A good Plus build is designed around the specific features you're paying for. If none of them apply to you yet, we'll say so. Our Shopify vs Shopify Plus guide walks through the thresholds and the math.

Built for speed and conversion from the start

Most slow Shopify stores are slow because of what got bolted on later: apps, scripts, and oversized images. We build lean, scope app scripts to the pages that need them, and wire analytics and conversion tracking in before launch rather than after. That way the first month of data is data you can trust. Accessibility and mobile QA happen on real devices, not just a desktop browser.

Large catalogs and complex integrations

We've built stores around catalogs most themes weren't designed for. That includes NVMOS, which went from concept to a live Shopify store with 75,000+ SKUs and live inventory sync in under 90 days. ERP, 3PL, PIM, review, and email integrations are planned during discovery, not discovered during QA. If you're coming from another platform, the build runs alongside a full platform migration so rankings and order history come with you.

After launch

A launch is where real traffic starts telling you what to improve. Many clients keep us on to iterate, whether that's new features, speed work or conversion testing. Others take the keys and run it themselves. Either way, you own the code.
