Shopify development services for brands that need more than a theme
Our Shopify development services cover custom themes, custom apps, checkout extensions and integrations — for brands whose store has outgrown what an off-the-shelf theme and app store can do.
We work as your Shopify development agency from first theme to Shopify Plus, with the same senior team throughout.
Shopify development for growing brands
Shopify takes care of hosting, security and checkout, which is why so many brands choose it. The limits show up when your products, pricing or operations do not fit a standard theme and a stack of paid apps.
We build custom themes on Online Store 2.0 so your team can still edit sections in the theme editor, and we write custom apps when a requirement — a configurator, a wholesale portal, an ERP sync — is specific to your business.
If you are moving from WooCommerce, Magento or BigCommerce, we migrate products, customers, orders and URLs so you keep your search traffic.
What custom Shopify development adds
A store that fits
Product pages, bundles and configurators designed around how you sell.
Fewer paid apps
One custom app can replace several subscriptions that overlap.
Connected operations
Orders, stock and customers flow to your ERP, 3PL and CRM automatically.

Why choose API Pilot as your Shopify development agency

Weekly working demos
Something you can click every Friday, so problems surface while they are still cheap to fix.

A public app is sold to many stores in the Shopify App Store. A custom app is built for your store only, around your workflow, and you own it.
