A Shopify Expert Agency That Actually Builds.
Most Shopify agencies are configurators. They install themes and apps. We do that when it’s the right call, and we engineer custom when it isn’t. Real development on top of Shopify, for brands that need more than a template.

What “expert” means
Anyone can say “Shopify expert.”
Here’s what it means at Byteout: 15 years building ecommerce, 200+ projects shipped, an official Shopify certification, and a team of senior engineers who’ve seen most of the ways these builds go wrong, and how to avoid them.
More importantly, it means we build what the app store can’t. Custom storefront features. Integrations with your ERP, 3PL, and Amazon. Internal tools, AI features, automations. When off-the-shelf Shopify can’t do what your business needs, that’s where most agencies stop. We keep going.
The difference
Configurators install. Engineers build.
The Shopify app marketplace covers maybe 80% of what most brands need. The other 20%, the part specific to how your business actually runs, usually doesn’t exist as a plugin. That gap is what we’re built for.

Install a theme, wire up off-the-shelf apps, hand over the keys. Fine when your needs fit what already exists, and most agencies stop exactly here, because the next step takes engineers.

Who we build for
We don’t build for everyone.
We focus on established Amazon sellers and consumer brands in health, beauty, supplements, and pet wellness. Most of them are building a DTC pillar they own alongside the marketplace. That focus matters: we understand the marketplace math most Shopify agencies have never touched, so we won’t build you a store that quietly cannibalizes your best-selling ASINs.
Building the Shopify side of an Amazon business is the core of what we do. We help you run it as one omnichannel business, where Amazon and your own store work together instead of competing.
Proof
Real builds, real brands.
Not stock logos. Real consumer brands we’ve built or rebuilt across health, beauty, supplements, and pet wellness.
FAQ
What buyers ask before they hire us.
Are you actually Shopify certified?
Yes, we’re Shopify certified, on top of 15 years building ecommerce and 200+ projects shipped.
Do you only build themes, or real custom development?
Both. We’ll configure off-the-shelf themes and apps when that’s the right call, and engineer custom when it isn’t. Integrations, internal tools, AI features, bespoke Shopify functionality: when the plugin store ends, we keep building.
Do you work with Shopify Plus?
Yes. Shopify Plus migrations and bespoke Plus development are core work, including high-volume stores and multi-currency, multi-region setups.
Can you migrate us without losing SEO or data?
Yes. We migrate from WooCommerce, Magento, BigCommerce, or custom platforms with data integrity and search rankings preserved. That’s the part rushed migrations get wrong.
Where are you based?
Belgrade. We’re a senior in-house engineering team, and we don’t hide it. You work directly with the people building your store, not a sales layer or an offshore handoff.
