Can you build both the Shopify app and the backend service it connects to?

Yes. For connector projects, we build both sides — the Shopify app and the API service that connects to your ERP, 3PL, or CRM. We host the backend on your infrastructure or manage it for you.

What is the difference between a public and private Shopify app?

A public app is listed on the Shopify App Store and can be installed by any merchant. A private app — or custom app — is used by a single store and does not require App Store review. We build both, depending on your distribution requirements.

Do you support the Shopify checkout extensibility model?

Yes. We build with Shopify Functions and the UI Extension framework that replaced checkout scripts for Shopify Plus stores. If you have existing checkout scripts, we can also migrate them to the new model.

The Problem

Shopify Extension Projects Fail Without Platform Depth

APP DEVELOPMENT COMPLEXITY

Shopify's architecture has changed significantly — the move to Shopify Functions, checkout extensions, and the GraphQL API has left many development teams behind. Merchants who rely on third-party developers unfamiliar with current Shopify standards end up with apps that fail the App Store review, break on checkout changes, or cannot scale with Plus store volumes.

Most Shopify extension failures are architecture decisions made before a line of code was written.

App Store Rejections

Apps that miss Shopify design standards, GDPR requirements, or API usage guidelines are rejected — often repeatedly.

Checkout Extension Complexity

Shopify checkout extensibility requires Shopify Functions expertise most teams do not have.

Performance at Plus Scale

Apps that work fine on small stores fail under Shopify Plus volumes due to rate limiting or webhook processing delays.

Integration Drift

Custom connectors built without proper webhook and retry logic silently fail and corrupt data.

Our Solution

How We Build Shopify Apps

Every engagement starts with Shopify API architecture — not code.

Scoping and API Design

We map your requirements to the Shopify API surface — Admin GraphQL, Storefront API, Functions, and Checkout Extensions — and define the architecture.

OAuth and Security Setup

We configure the Shopify OAuth flow, scope management, and webhook verification to Shopify security requirements.

App Development

We build the app using Shopify CLI, Polaris components for admin UI, and Shopify Functions or checkout extensions where required.

App Review Preparation

We test against Shopify App Store review criteria and prepare submission documentation.

Launch and Monitoring

We deploy to production, configure webhook monitoring, and provide a 30-day support window post-launch.
