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.
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.
Built around your needs
Connect your essential tools
Extend your store capabilities
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.”
