Custom Shopify Apps and Integrations, Built to the Shopify Standard
We build embedded Shopify admin apps, storefront extensions, and API connectors that integrate your Shopify Plus store with the systems your business runs on.
The Problem
Shopify Extension Projects Fail Without Platform Depth
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.

FAQs
Common questions
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.
