Liquid Web Developers

Shopify app developers

Shopify App Development

When off-the-shelf apps fall short, we build your own. Custom Shopify apps and integrations — embedded admin tools, storefront extensions, and private apps engineered on App Bridge and the GraphQL APIs — that automate your workflows and connect the systems your store depends on.

In short

Shopify app developers build custom apps that extend Shopify — embedded admin apps, storefront features, and integrations — using the Admin and Storefront GraphQL APIs, App Bridge, and webhooks. Apps can be public (App Store) or custom apps built for a single merchant.

When your needs outgrow what existing apps offer, a custom Shopify app gives you exactly the functionality you want without the bloat and recurring fees of multiple third-party tools. We build custom (single-merchant) apps and public App Store apps using Shopify’s modern toolchain.

From embedded admin tools your team uses daily, to storefront features, to backend integrations with ERPs and 3PLs, we build secure, performant apps on the Admin and Storefront GraphQL APIs with proper OAuth, webhooks, and App Bridge UI.

Benefits

Built around you, not a template

Your app mirrors exactly how you operate — no bending your business to another tool's assumptions.

One app, not ten

Collapse a stack of overlapping apps and their monthly fees into a single, focused solution you own.

Secure by design

OAuth, scopes, webhooks, and GDPR mandatory webhooks handled properly — locked down and compliant from day one.

Feels native to Shopify

Embedded apps built with App Bridge and Polaris that live inside your admin like they belong there.

Lighter, faster storefront

Lean, purpose-built code instead of bloated third-party scripts — so custom functionality never costs you speed.

Connected to everything

Wire your store to ERPs, CRMs, and the systems you already run, so data flows automatically and nothing's re-keyed.

📲 Custom (private) apps

For functionality only your store needs — internal tooling, custom integrations, or bespoke storefront features — we build custom apps scoped to your store, with no App Store listing or review required.

📱 Public App Store apps

Building a product? We help take a public app from concept to App Store, including App Bridge embedding, billing API, listing requirements, and the Shopify app review process.

⚒️ Integrations & automation

We connect Shopify to ERPs, 3PLs, PIMs, CRMs, and custom systems via the Admin GraphQL API and webhooks, building reliable sync and automation with proper retry and error handling.

Social proof

What clients say

I always dreamed about a fascinating e-commerce store for my footwear brand. I looked for various Shopify store development companies and finally, they got my attention with their robust portfolio. Their professionals answered my queries at the right time and delivered the product at the decided time. I recommend you hire their Shopify experts to get an unparallel experience.

Before Liquid Web Developers, every little bug on our store turned into a stressful scramble. Now I just message the team and it's handled — usually before I've finished my coffee. Their maintenance plan keeps everything fast and secure, and knowing someone's always watching the store has genuinely taken the pressure off. Honestly, it's the best money we spend each month.

What I love most is that things just… don't break anymore. The Liquid Web Developers team stays ahead of updates, monitoring, and performance before any of it becomes my problem. I used to lie awake worrying about downtime during a big sale; now I don't think about it at all. Reliable, proactive, and refreshingly easy to work with — exactly what I needed.

Frequently asked questions

They build custom apps that extend Shopify — embedded admin tools, storefront features, and backend integrations — using the Admin and Storefront GraphQL APIs, App Bridge, Polaris, and webhooks. Apps can be public (App Store) or custom apps for a single merchant.

A custom app is built and installed for one specific store and does not go through App Store review; a public app is listed on the Shopify App Store, supports many merchants, and must pass Shopify’s review and requirements.

Simple custom apps often start around $8,000–$15,000, while complex public apps with billing and multi-tenant infrastructure can run $30,000+. Cost depends on scope, integrations, and ongoing maintenance.

Often yes. Consolidating several overlapping subscription apps into one owned custom app can lower recurring costs and remove unneeded features that slow your store.
