E-Commerce Development

In 2026, your e-commerce platform is not just a store — it is your most valuable business asset. At Core Chunk, we build complete, end-to-end e-commerce solutions that cover every layer of the commerce stack: from pixel-perfect storefronts and intelligent product catalogs to distributed order management, third-party integrations, and post-sale analytics. We serve every type of commerce — B2C retail, B2B wholesale, D2C brands, multi-vendor marketplaces, service bookings, and digital downloads — all at prices that make enterprise-grade technology accessible to businesses of every size. Our philosophy is simple: you should not have to choose between features and affordability.

Every Type of E-Commerce, Built from the Ground Up We do not specialise in one type of store — we build them all. Core Chunk delivers custom B2C storefronts for retail brands, B2B portals with quote management and bulk ordering for wholesale businesses, D2C subscription boxes with recurring billing and customer portals, multi-vendor marketplaces where hundreds of sellers list and manage their own inventory, hyperlocal delivery platforms, digital goods stores for software, courses, and media, and service-booking commerce where appointment scheduling and payment happen in a single flow. Whatever your business model, we architect the solution around your specific revenue logic — not around the limitations of a generic template.

Storefront Excellence: Design That Converts Every page of your store is a salesperson that works 24/7. Core Chunk engineers "Conversion-First Storefronts." We design and build pixel-perfect, brand-consistent UIs with clear visual hierarchy, trust signals (reviews, badges, guarantees), and micro-interactions that guide the customer toward the checkout with zero friction. Our product pages are built with "Psychological Persuasion Architecture" — social proof, scarcity indicators, comparison tables, rich media galleries, and 360-degree product views. We implement "Smart Cross-Selling and Upselling" widgets that appear at precisely the right moment in the buyer's journey, increasing average order value without disrupting the purchase flow.

Performance Engineering: Speed Is Revenue In e-commerce, a one-second delay costs real money. Core Chunk treats speed as a core feature. We build on Next.js with Streaming Server-Side Rendering, Partial Prerendering, and edge caching to deliver sub-second product page loads even for catalogs with tens of thousands of SKUs. We implement advanced image optimization pipelines (WebP/AVIF conversion, lazy loading, responsive srcsets), CDN-level caching for product data, and predictive prefetching that silently loads the next likely page before the user clicks. Every store we build achieves a Lighthouse performance score above 90 and passes Google's Core Web Vitals — ensuring both a fast user experience and high organic search rankings.

Product Catalog and Inventory Management Managing products at scale requires a serious backend. We build intelligent catalog systems that support unlimited product variants (size, color, material, configuration), configurable attributes, product bundles, digital goods, and virtual products. Our inventory engine supports real-time stock tracking across multiple warehouses and locations, low-stock alerts, automatic reorder triggers, and reserved inventory logic for high-demand flash sales. We build "Multi-Location Inventory Distribution" so that orders are automatically routed to the nearest fulfillment center, reducing shipping times and costs for your customers.

Distributed Architecture for Scale and Resilience High-traffic events — festival sales, product launches, viral moments — can destroy a poorly architected store. Core Chunk builds e-commerce platforms on a distributed, cloud-native architecture designed to handle sudden traffic surges of 100x normal load without a millisecond of downtime. We use horizontally scalable microservices, message queues (Redis, RabbitMQ) to decouple order processing from the storefront, and database read replicas to handle massive concurrent reads during peak traffic. Our systems auto-scale in seconds using Kubernetes or serverless infrastructure, ensuring your store is always available, no matter how many customers arrive at once.

Intelligent Search and Product Discovery A customer who cannot find a product will not buy it. We build "Intelligent Commerce Search" that goes far beyond a basic keyword search bar. Using Algolia or Elasticsearch with semantic vector enhancements, our search understands typos, synonyms, natural language queries, and intent. We implement fully customizable faceted filtering — filter by price, brand, rating, availability, color, size, and any custom attribute — with instant results that update as the user types. Our AI-powered recommendation engine analyzes browsing history, purchase patterns, and collaborative filtering signals to surface "Customers Also Bought," "Recently Viewed," "Trending Now," and personalized homepage feeds that significantly increase session depth and basket size.

Complete Checkout and Payment Infrastructure The checkout is the most critical conversion point. Core Chunk builds checkout flows that are fast, trusted, and universal. We support guest checkout, registered accounts, and social login (Google, Facebook). We implement one-page checkouts, address auto-complete, and saved payment methods for returning customers. On the payment side, we integrate every major gateway — Razorpay, Stripe, PayU, CCAvenue, PhonePe, Google Pay, Apple Pay, and PayPal — alongside UPI, net banking, EMI options, and Buy Now Pay Later providers like Simpl and LazyPay. Our "Smart Payment Routing" selects the gateway with the highest authorization rate for each transaction, and all checkouts are PCI-DSS compliant with 3D Secure authentication and real-time fraud detection.

Order Management System (OMS) We build a complete Order Management System that tracks every order from the moment of placement through to delivery and beyond. Features include real-time order status updates, automated email and SMS notifications at every stage, split-order handling for multi-vendor carts, partial fulfillment, backorder management, and return merchandise authorization (RMA). Our OMS integrates directly with your warehouse management software, shipping providers (Shiprocket, Delhivery, BlueDart, FedEx, DHL), and ERP platforms to create a fully automated fulfillment pipeline that requires zero manual intervention for standard orders.

Returns, Refunds, and After-Sale Operations The post-purchase experience is where customer loyalty is built or destroyed. Core Chunk builds self-service return portals where customers can initiate returns, select reasons, generate shipping labels, and track refund status without ever contacting support. We automate refund processing for eligible orders, implement store credit and exchange workflows, and provide your operations team with a complete returns dashboard that identifies the most common return reasons by product — giving you actionable data to reduce return rates over time.

Multi-Channel and Omnichannel Commerce Modern commerce does not live on a single channel. Core Chunk builds the integration layer that connects your central catalog and inventory to every sales channel simultaneously. We sync your products to Amazon, Flipkart, Meesho, and Google Shopping. We enable direct selling through WhatsApp Commerce and Instagram Shopping. We build the bridge between your online store and physical retail through POS integration, ensuring that your inventory, pricing, and promotions are always in sync across every touchpoint. Customers can buy online and pick up in-store (BOPIS), return in-store items bought online, and access their full purchase history across all channels.

Third-Party Integrations: Every Tool You Already Use No e-commerce business runs on a single platform. Core Chunk integrates your store with the full ecosystem of tools you depend on. On the marketing side, we connect with Klaviyo, Mailchimp, and WhatsApp Business for automated campaigns; with Google Ads, Meta Ads, and TikTok Ads for conversion tracking and dynamic product ads. On the operations side, we integrate with Zoho, Tally, and QuickBooks for accounting; with Salesforce and HubSpot for CRM; with Zendesk and Freshdesk for customer support; with ShipStation and EasyShip for logistics. We build custom API connectors for any proprietary tool or ERP system your business runs on — if it has an API, we can connect it.

Mobile Commerce: Native Apps and PWA In India, over 70% of online shopping happens on mobile. Core Chunk builds mobile-first commerce as a non-negotiable standard. For most businesses, we build Progressive Web Apps (PWA) that install directly from the browser, work offline, and send push notifications — delivering the experience of a native app at a fraction of the cost. For high-volume brands, we build fully native iOS and Android shopping apps with biometric authentication, one-tap checkout, real-time order tracking, personalized push notifications, and loyalty program integration. Both options are built with performance and conversion as the primary design constraint.

Customer Accounts, Loyalty, and Retention Acquiring a customer is expensive. Keeping them is where the margin lives. Core Chunk builds comprehensive customer account portals with order history, saved addresses, wishlist management, and account-level pricing for B2B customers. We build loyalty and rewards programs — points for purchases, referral bonuses, tier-based discounts — that create behavioral loops that keep customers coming back. We implement "Winback Automation" that detects dormant customers and sends personalized re-engagement offers, and "Subscription Commerce" flows for products that customers buy repeatedly, converting one-time buyers into predictable recurring revenue.

Promotions, Discounts, and Marketing Tools We build a full-featured promotions engine that gives your marketing team complete control without developer intervention. This includes percentage and fixed-amount discount codes, cart-level and product-level promotions, BOGO (buy one get one) deals, bundle discounts, minimum order thresholds, customer-segment-specific pricing, flash sale scheduling, and affiliate/referral tracking. We integrate these promotions directly with your email and SMS marketing tools so that a campaign creation in Klaviyo automatically generates the corresponding discount code in your store.

SEO: Built In, Not Bolted On Organic search is the highest-ROI acquisition channel in e-commerce. Core Chunk bakes technical SEO into the architecture of every store. Every product and category page is server-side rendered for perfect crawlability, with schema markup for Product, Offer, Review, and BreadcrumbList structured data that unlocks rich snippets in Google Search. We implement canonical tags to prevent duplicate content across variant URLs, hreflang for international stores, dynamic XML sitemaps that update in real-time as products are added or removed, and optimized URL structures for category hierarchy. The result is a store that ranks organically for thousands of long-tail product searches without ongoing ad spend.

Analytics, Reporting, and Revenue Intelligence You cannot grow what you do not measure. Core Chunk builds "Commerce Intelligence Dashboards" that surface every metric you need: conversion rate by traffic source, average order value by product category, customer lifetime value by acquisition channel, cart abandonment rate by checkout step, and return rate by product. We implement server-side analytics with GA4 and BigQuery for 100% data accuracy in a cookie-less world, and integrate with Google Merchant Center for Shopping campaign performance. We set up enhanced e-commerce tracking for every funnel event — product views, add-to-cart, checkout initiation, purchase — and provide the reporting infrastructure to run continuous A/B tests on your most important pages.

Security, Compliance, and Fraud Prevention Trust is the foundation of e-commerce. Core Chunk builds security into every layer. All stores are served over HTTPS with HSTS, PCI-DSS compliant payment flows, and CSP (Content Security Policy) headers to prevent XSS attacks. We implement bot protection and rate limiting on checkout and login endpoints to prevent credential stuffing and inventory hoarding. For businesses handling sensitive customer data, we provide GDPR-compliant cookie consent management, data export and deletion flows for customer requests, and full audit logs. Our fraud detection layer analyzes order signals in real-time — IP reputation, device fingerprinting, velocity checks — to automatically flag or block high-risk transactions before they are processed.

Affordable Pricing, Enterprise Results Enterprise-grade e-commerce should not require an enterprise budget. Core Chunk delivers fully custom, scalable, feature-rich stores at prices accessible to startups, SMBs, and growing brands. We don't charge for features you don't need, and we don't lock you into proprietary platforms with ongoing licensing fees. You own your code, your data, and your infrastructure. Our transparent pricing model means you know exactly what you are getting before a line of code is written. Whether you need a lean 10-product store launched in two weeks or a complex, distributed marketplace handling 10,000 orders a day, Core Chunk scales its delivery to match your ambition and your budget.
