ecommerce app development is the process of designing and building mobile or web applications that allow businesses to sell products and services online. It covers everything from the UI a customer sees on their phone to the checkout flow, payment processing, order management, and the admin tools your operations team relies on.
A dedicated ecommerce app is not just a mobile version of your website. Done properly, it is a faster, more personalised, and more conversion-optimised buying experience that keeps customers coming back. Push notifications bring shoppers back when they have abandoned a cart. Native payment flows reduce friction at checkout. Personalised product feeds — powered by purchase history and behaviour data — surface the right product to the right person at the right time.
The numbers make the case plainly. Mobile commerce accounts for more than 70% of global ecommerce traffic, and apps consistently outperform mobile web on session length, repeat visits, and conversion rate. Businesses that invested in a dedicated ecommerce app early have a meaningful structural advantage over competitors still relying on responsive web alone.
At Gree Web Solutions, we have delivered mobile application development and ecommerce app development services for retail brands, B2B suppliers, and marketplace platforms across the USA, UK, India, and beyond — building apps that are fast, secure, and genuinely good to use.
Not every ecommerce app is the same. We build across every major ecommerce model — matching the architecture, feature set, and UX to the specific way your business sells and the customers you serve.
B2C ecommerce App
Consumer-facing shopping apps for retail brands, fashion labels, electronics stores, beauty brands, and direct-to-consumer businesses. We design B2C apps around the complete buyer journey — product discovery, detailed product pages, seamless checkout, order tracking, and loyalty programmes — all optimised for conversion and retention.
B2B ecommerce App
ecommerce applications built for the complexity of business-to-business trade — bulk ordering, negotiated pricing tiers, multi-user company accounts, purchase approval workflows, credit terms, invoice management, and integration with ERP and procurement systems. We have built B2B ecommerce apps for distributors, manufacturers, and wholesale suppliers.
Marketplace App
Multi-vendor marketplace platforms where multiple sellers list and sell to a shared buyer base — like Amazon, Etsy, or vertical-specific B2B marketplaces. We build the seller onboarding, product listing, order routing, commission management, dispute resolution, and admin dashboard infrastructure that makes a marketplace run reliably at scale.
Subscription Commerce App
Apps built around recurring revenue — subscription boxes, SaaS-style software products, membership access, and D2C subscription models. We handle subscription billing, pausing, cancellation flows, dunning management, and the user account experience that keeps churn low and lifetime value high.
Food & Grocery Delivery App
On-demand commerce apps for restaurants, dark kitchens, grocery chains, and quick-commerce businesses. Real-time order tracking, driver dispatch, dynamic ETA calculations, inventory management, and the operational dashboards restaurant and operations managers actually need.
Progressive Web App (PWA)
A single codebase that works like a native app on any device without requiring an App Store download. PWAs are ideal for businesses that want native-like ecommerce performance — offline mode, push notifications, home screen install — without the overhead of maintaining separate iOS and Android builds.
From strategy and design to development, launch, and post-launch support — our ecommerce app development company handles every stage so you get a finished, working product, not a handoff midway.

Shopify, WooCommerce, Magento, SAP, Salesforce, and custom ERP integrations — we connect your app to your existing stack.

There are many agencies that claim to do ecommerce app development. Here is what makes the difference when you are choosing who to build with.
Ecommerce-Specific Expertise
We focus on ecommerce. That means we know what causes cart abandonment, which checkout flows convert, how to architect a product catalogue for scale, and what actually drives app store ratings upward.
Performance-First Development
Slow apps lose sales. Every app we build is optimised for sub-2-second load times, smooth 60fps animations, and reliable performance under peak traffic — because your biggest sales day should not also be your worst.
Security & PCI Compliance
We build ecommerce apps with payment security as a core requirement — PCI-DSS compliant payment flows, encrypted data storage, secure API architecture, and regular security audits throughout development.
Global Delivery, Affordable Rates
Our team is based in India, which means global-standard quality at rates that give you significantly more for your development budget than equivalent agencies in the USA or UK — without compromising on output.
Analytics & Conversion Optimisation
We build analytics into every ecommerce app from day one — tracking funnels, heatmaps, product performance, and checkout flow events — so you have the data to make informed decisions post-launch.
Ongoing Support & Iteration
We do not disappear after launch. Our post-launch support covers bug fixes, performance monitoring, OS update compatibility, and feature development as your business and customer needs evolve.
