Why Custom Development

When no existing app does what you need — we build it

The Shopify App Store has 10,000+ apps, but none of them were designed for your specific workflow. We build custom Shopify apps that solve the exact problems your business faces — whether that is a private app to sync your ERP, a custom product configurator, or a public app destined for the App Store. Built with Remix, Polaris, and App Bridge for a seamless admin experience.

A

Admin-native experience

Every app we build uses Polaris for UI and App Bridge for navigation, so it feels like a native part of the Shopify admin. Merchants never have to learn a new interface — it just works.

I

API-first architecture

Built on the Admin API, Storefront API, and webhooks with GraphQL. Real-time data sync, efficient queries, and rock-solid reliability. No polling, no stale data, no surprises.

S

App Store ready

We handle the full lifecycle — from concept to Shopify App Store submission. App review compliance, listing copy, screenshots, billing integration, and merchant onboarding built in.

What's Included

Everything you need for a successful Shopify launch

01

Discovery & Requirements

Deep-dive into your workflow, pain points, and objectives. We map the user stories, data model, and API touchpoints before writing code — ensuring the app solves the right problems.

UX Design & Prototyping

Wireframes and interactive prototypes using Polaris components. We validate the user experience with your team before development, so the final app feels intuitive from day one.

02

Remix + Polaris Frontend

Server-rendered React frontend built with Remix and Polaris. App Bridge integration for seamless navigation, contextual save bars, resource pickers, and toast notifications.

API & Webhook Backend

GraphQL Admin API for data operations, REST where needed, and webhook subscriptions for real-time events. Prisma ORM with PostgreSQL for app data persistence.

03

Storefront Integration

Theme app extensions, app blocks, and Storefront API integrations for customer-facing functionality. Script tags and dynamic content injection when needed.

Billing & Subscription

Shopify Billing API integration for recurring charges, usage-based pricing, and one-time purchases. Free plan tiers, trial periods, and upgrade flows built in.

04

Testing & QA

Unit tests, integration tests, and end-to-end testing across development and production stores. OAuth flow testing, webhook validation, and rate limit handling.

App Store Submission

Full App Store listing — copy, screenshots, demo video, review compliance, and submission management. We handle the review process and iterate until approval.

Frequently Asked Questions

Common questions about custom development

A private app (now called custom apps) is built for a single store — typically for internal tools, ERP integrations, or custom workflows. A public app is listed on the Shopify App Store and can be installed by any merchant. Public apps require OAuth, billing integration, and App Store review approval.

We build on the official Shopify app stack: Remix for the frontend with Polaris components and App Bridge, Node.js for the backend, Prisma with PostgreSQL for data, and the Shopify CLI for development and deployment. This ensures long-term compatibility and easy maintenance.

A private app or simple integration typically takes 3–5 weeks. A full public app with billing, onboarding, and App Store submission takes 8–14 weeks. Complex apps with multiple features can take 4–6 months. We provide a detailed timeline during the scoping phase.

Yes. We handle the full App Store submission process — listing copy, screenshots, demo video, compliance checks, and review management. We build to Shopify review guidelines from day one, so most apps are approved on the first submission.

Yes. We deploy apps on Fly.io, Railway, or AWS depending on scale requirements. Infrastructure includes database hosting, background job processing, CDN for assets, and monitoring. We set up CI/CD pipelines so deployments are automated and reliable.

Absolutely. We regularly build apps that sync Shopify with ERPs (NetSuite, SAP), warehouses (ShipBob, ShipStation), CRMs (HubSpot, Salesforce), marketing tools (Klaviyo, Attentive), and custom internal systems via REST or GraphQL APIs.

Every project includes 30–60 days of post-launch support. For ongoing maintenance, we offer monthly retainer plans covering feature development, bug fixes, Shopify API updates, performance monitoring, and App Store review support.
