Shopify App Development

Make your business unique.

About Shopify Apps

Shopipfy Apps are the fundamental building blocks behind every great Shopify-powered store experience. Without a strong eCommerce foundation of critical apps, you risk missing out on features and even potential sales opportunities.

Private Apps

Shopify provides a robust and feature-rich eCommerce platform that suits most enterprises. But what happens when you need something specific that’s unique to your business, but isn’t exist Shopify App?

With Tetralogicx you can build Privet Apps with custom functionalities that will be specific only for your store needs.

Public Apps

Think you’ve got an idea for an app no one invented before? Or whether your business is already providing a unique service. You can sell it on the Shopify App Store!

Our development team can build public apps for you to list and sell in the Shopify store under your name. We can help you create an app to integrate your solution into merchants’ stores. If you want to convert an online service into a Shopify integration, but don’t have the resource to build your own public app, we can build it to your specification, under your name.
