What you get
Shopify development, done properly
Your Shopify store should not need a developer for every product launch, landing page, or merchandising change. We build custom Shopify and Shopify Plus stores for DTC teams that need better speed, cleaner UX, stronger SEO foundations, and fewer operational workarounds.
You work directly with a senior developer from planning through launch. Bytecode is based in New York and serves brands across the US and Canada, with replies to new inquiries within 24 hours.
Custom Shopify themes
You get a theme built around your brand, catalog, content, and buying path. We keep it maintainable so your team can edit key pages without breaking the store.
Shopify Plus builds
We build and rebuild Shopify Plus storefronts for larger catalogs, higher order volume, and more complex operations. That includes checkout setup, storefront structure, and admin workflows.
App setup and custom apps
We configure the apps you need and remove the ones slowing you down. When an off-the-shelf app is not the right fit, we can build custom Shopify app functionality.
ERP and inventory integrations
We connect Shopify with inventory, fulfillment, CRM, analytics, and marketing systems. The goal is fewer manual updates and fewer order issues.
Speed and SEO fixes
We improve theme performance, page structure, metadata, redirects, schema, and crawl paths. You can also start with a free Shopify speed and SEO audit at free audit.
Conversion-focused UX
We review product pages, collection pages, navigation, cart behavior, and checkout friction. Then we turn the findings into practical design and development work.

FAQ
Questions, answered
What does a Shopify development agency do?
A Shopify development agency plans, designs, builds, integrates, and maintains Shopify stores. That can include custom themes, Shopify Plus builds, app setup, custom apps, SEO fixes, speed work, and integrations with business systems. The right work depends on your catalog, team, traffic sources, and operations.
Do you build custom Shopify themes?
Yes. We build custom Shopify themes for brands that have outgrown a generic template or need tighter control over product pages, collection pages, content sections, and performance. We also make the theme manageable for your team after launch.
Can you rebuild an existing Shopify store?
Yes. We can rebuild your current Shopify store without forcing unnecessary platform changes. We review what is working, what is slowing the business down, and what needs to be restructured before development starts.
Do you work with Shopify Plus?
Yes. We build and improve Shopify Plus stores, including storefront structure, checkout setup, app architecture, performance, SEO, and integrations.
Can you connect Shopify with our other systems?
Yes. We connect Shopify with inventory, fulfillment, CRM, analytics, marketing, and other operational tools when the APIs and access allow it. We start by mapping the data flow so the integration solves the actual workflow problem.
How do we start?
Send your store URL, goals, and the main issues you want fixed. Bytecode replies to inquiries within 24 hours. If speed and SEO are your first concern, you can start with the free Shopify speed and SEO audit at free audit.
