Trusted by clients across USA, UK, Canada and India.
A Shopify Development Company That Builds Custom Themes, Shopify Plus Extensions, and Flutter Mobile Apps
Most Shopify merchants reach the same ceiling: a generic ThemeForest theme that looks identical to thousands of other stores, or a Shopify Plus merchant whose standard checkout is blocking revenue that custom checkout extensibility would capture. Both problems share the same root cause — no Shopify partner thinking about the full commerce platform, from theme to checkout to mobile.
We build custom Shopify themes from Figma designs in Liquid — every section, template, and Gutenberg-equivalent block built specifically for your product category and brand identity. For Shopify Plus merchants, we build checkout extensions with custom UI components, post-purchase upsells, loyalty integration, and B2B pricing logic using the Checkout UI Extensions API. And we build the Flutter iOS and Android mobile app on your Shopify Storefront API — same team, same architecture, same fixed-price model. One Shopify backend serving your web store and mobile app simultaneously. Our AI-powered development pipeline builds custom Shopify apps with OpenAI integration — AI product recommendations, intelligent search, and automated content generation built as proper Shopify apps in the Admin under your full control.
Every Shopify project we deliver targets Lighthouse scores above 90 — custom Liquid with no unnecessary plugin weight, image compression via the Shopify CDN pipeline, and Core Web Vitals compliance measured at every sprint. For Shopify App Store development, we build using Shopify CLI, Remix for the app frontend, Admin API and GraphQL, Polaris design system, Webhooks, and the Shopify billing API for subscription monetisation.

Real Shopify Challenges.
Every project carries risks — poor UX, missed deadlines, underperforming results. Here is how we eliminate each one.
How We Deliver Shopify Projects
A six-stage delivery process designed for overseas clients — every sprint delivers a working development store preview, every invoice is tied to a deliverable. The same discipline whether building your <a href="/mobile-app-development-company-india/" class="content-link">Shopify store or the Flutter mobile app</a> on the Storefront API. No black-box development. No surprises at launch.
Discovery & Shopify Architecture
We begin with a structured discovery call to understand your Shopify project — merchant store scope or App Store app requirements, Shopify vs Shopify Plus tier decision, third-party integrations, payment and shipping configuration, and Storefront API requirements for headless builds or Flutter mobile extension.
Design & Liquid Architecture
For store development, every theme template and section is designed in Figma and approved before Liquid development begins. For app development, Admin embed UI and App Store listing assets are designed and agreed. Checkout flow is user-tested in Figma before any Liquid or Remix code is written.
Fixed-Price Proposal
A fixed-price proposal covers the complete Shopify scope — custom theme or app development, API integrations, Shopify Plus configuration if applicable, App Store submission requirements, testing, and launch support. One price. No hourly billing. No scope creep on agreed features.
Shopify Liquid & Remix Development
Store development runs in two-week sprints using Shopify Liquid with Shopify CLI. App development uses Remix with Shopify App Bridge. You receive a working development store preview at the end of every sprint — testable with real product data — so you see real progress throughout the project.
QA — Performance, Checkout and Compliance
Every Shopify build is tested with Lighthouse Core Web Vitals audits, cross-browser and cross-device checkout flow testing, all payment gateway test mode transactions, Shopify theme or app review guideline compliance checks, and cookie consent validation before production launch.
Launch & Mobile Extension
We manage complete Shopify store launch — domain, payment activation, shipping zones, and App Store submission for app projects. Post-launch support included for 60 days. When your Shopify customers need a native mobile app — our team builds the Flutter iOS and Android app on the Shopify Storefront API.
Industry-Specific Shopify Development
We deliver AI solutions for Shopify and Shopify Plus stores across the industries where D2C commerce, conversion optimisation, and scalable ecommerce infrastructure create the strongest revenue outcomes — retail, food and restaurant, and sports.

Every Shopify project at AZRIVA is fixed price — scoped completely before development begins. Pricing depends on scope, Shopify Plus requirements, App Store development, and whether the project includes a Flutter mobile extension.
All pricing is fixed — the number in your proposal is the number on your invoice. Clients who extend their Shopify store to Flutter mobile app development receive the same fixed-price model for the mobile project. VAT/GST applicable for Indian clients.
How We Engage With Businesses
Whether you need a fixed-price custom Shopify store, a Shopify Plus enterprise build with checkout extensibility, or a Shopify App Store product for other merchants — three engagement models designed for different business stages.
Custom Shopify store scope defined and priced before development begins — Liquid theme, integrations, checkout configuration, and Storefront API ready for Flutter mobile. One fixed price. No hourly billing. Same model extends to mobile when your customers need an app.
Shopify Plus checkout extensibility, custom UI components, B2B features, and loyalty integration — all at a fixed price. Enterprise Shopify development for merchants processing $1M+ annually who need checkout logic that standard Shopify cannot deliver.
