A Shopify store with a free theme gets you online. It does not get you a checkout flow optimised for Indian payment behaviour, an order management system that talks to your warehouse, a returns process that does not require your team to manually track WhatsApp messages, or the flexibility to build the product experience your category needs. We build eCommerce that is designed around your specific product, customer, and operational reality.

Marketing Wise

From product listing to repeat purchase —We build eCommerce stores for clients based in Noida, Delhi & NCR, India

Marketing Wise has delivered 50+ eCommerce builds for D2C brands, B2B wholesale portals, multi-brand marketplaces, and omnichannel retailers across Noida, Delhi, Gurugram, and Greater Noida. Our eCommerce builds range from focused direct-to-consumer stores for single-category brands to full-stack eCommerce platforms with multi-warehouse inventory, marketplace seller onboarding, and custom product configurators.

We build eCommerce with five performance-driving principles: conversion-first checkout (UPI-first payment flow, address autofill, and one-tap reorder for returning customers), product experience (rich media, variant management, and customisation options that reduce purchase hesitation), operational integration (order management connected to your warehouse, courier, and accounting systems), retention mechanics (loyalty points, abandoned cart recovery, and personalised recommendations), and scalability (architecture that handles traffic spikes on sale days without degrading performance).

  • Product catalogue with variants, rich media, bundles, and custom attributes
  • Conversion-optimised checkout with UPI, card, EMI, COD, and buy-now-pay-later
  • Order management — fulfilment workflow, courier integration, and shipment tracking
  • Inventory management with multi-warehouse support and low-stock alerts
  • Returns and exchange management with customer self-service portal
  • Analytics dashboard — revenue, conversion rate, AOV, repeat rate, and product performance
When should we build a custom eCommerce store instead of using Shopify?
Build custom when your product requires a buying experience Shopify's theme system cannot deliver — for example, a configurator where customers build a product with real-time pricing, a B2B store with customer-specific pricing and credit limits, a multi-vendor marketplace where each seller manages their own inventory, or a category where the standard product page layout significantly hurts conversion. Also consider custom when your operational backend (warehouse, ERP, custom pricing logic) needs tighter integration than Shopify's API model supports cleanly.
Can the store support UPI payments as the primary payment method?
Yes. We integrate Razorpay or PayU as the payment gateway, with UPI as the featured payment option in the checkout flow — UPI intent (opens the user's UPI app directly) and UPI QR for desktop. The payment sheet is designed for Indian payment behaviour: UPI first, saved cards second, net banking, COD, and EMI options clearly visible. Payment success rates on Indian checkouts are significantly affected by the payment UX — we optimise specifically for this.
Can the store integrate with our warehouse management system for order fulfilment?
Yes. We build warehouse integration where confirmed orders push to your WMS or inventory system automatically, pick-and-pack confirmation updates the order status in the store, and dispatch triggers the courier API call and sends the tracking link to the customer via WhatsApp. If you use a 3PL (third-party logistics provider), we integrate with their API. If your warehouse is manual, we build a simple WMS module within the eCommerce platform.
Can the store connect to multiple courier partners and auto-select based on pin code and cost?
Yes. We build multi-courier integration using Shiprocket, Delhivery, or direct courier APIs, with serviceability check at checkout (the store shows estimated delivery date for the customer's pin code), auto-selection of the most cost-effective serviceable courier for each order, and automated shipment creation and tracking number generation at dispatch. Customers receive WhatsApp tracking updates at key shipment events.
Can we have a customer self-service returns portal?
Yes. We build a returns portal where customers log in with their order number and email, select the items they want to return or exchange, specify the reason, and submit the request. The operations team reviews and approves the return, and the customer receives a pickup label or drop-off instructions automatically. Exchange requests generate a new order for the replacement item. Return status is visible to the customer throughout the process without them needing to contact support.
Can the store handle flash sales and high traffic events without going down?
Yes. We build eCommerce architecture with horizontal scaling capability — the application layer scales out during traffic spikes, inventory checks use Redis for high-throughput read operations, and payment processing is asynchronous so the store stays responsive during peak load. We conduct load testing before major sale events. CDN caching of product pages ensures static content loads fast regardless of backend load. Queue-based order processing prevents overselling during simultaneous checkout.
Can the store show personalised product recommendations?
Yes. We build recommendation systems ranging from rule-based (customers who bought X also bought Y, based on order history) to collaborative filtering (similar customer profiles suggest items). On the product page, cart, and post-purchase page, recommendations are rendered from the recommendation engine. Recommendation performance — click rate and conversion from recommendation — is tracked in the analytics dashboard.
Can we run a B2B wholesale store with customer-specific pricing?
Yes. We build B2B eCommerce with account-level pricing where each wholesale customer or customer tier sees their own price list. MOQ (minimum order quantity) rules, credit limit management, and purchase order reference fields at checkout are built for B2B workflows. A B2B customer logs in, sees their contract pricing, and checks out with a PO number. The order is flagged for credit limit validation before confirmation. Invoice generation is GST-compliant and formatted for B2B requirements.
Can the store integrate with Tally or our accounting software for sales entries?
Yes. We build accounting integration where confirmed and paid orders are exported to Tally as sales vouchers with the correct ledger, GST heads, and item details. The integration runs on a schedule (every 15 minutes or hourly) or in real time. This eliminates manual sales entry in Tally and ensures the accounts team always has current revenue data without accessing the eCommerce admin.
Can customers earn and redeem loyalty points on purchases?
Yes. We build loyalty programme management where customers earn points per rupee spent, with bonus points for first purchase, referrals, and special events. Points are redeemable against future orders at a configured conversion rate. Points balance is visible on the customer account page and in the checkout. Loyalty programme performance — points issued, points redeemed, redemption rate — is on the management dashboard.

Our process

No mystery phases. Four gates every eCommerce build crosses — from conversion audit to live store.

Product & conversion design

We audit your product catalogue, pricing model, target customer, current conversion funnel (if you have an existing store), operational workflow, and courier and payment requirements. Every page — homepage, category, product, cart, checkout, account — is wireframed and reviewed before development begins. Conversion-critical decisions (checkout flow, UPI placement, trust signals) are made at this stage.

Week 1–2

Core store build — catalogue, checkout, payments

Product catalogue with variants and rich media, shopping cart, checkout with payment gateway integration, order confirmation flow, customer account, and the operations order management dashboard are built. A full purchase cycle — from product page to payment to order confirmation to operations dashboard — is tested end-to-end before additional features are added.

Week 3–7

Fulfilment, inventory & retention features

Courier integration with shipment tracking, multi-warehouse inventory, returns portal, loyalty programme, abandoned cart recovery, product recommendations, and accounting integration are built. A pre-launch review covers checkout conversion, page speed (Core Web Vitals), and mobile experience on mid-range Android devices.

Week 8–12

SEO setup, load testing & go-live

SEO metadata, structured data, sitemap, and robots.txt are configured. Load testing at 3–5x expected peak traffic is conducted. The store goes live with analytics, error monitoring, and uptime alerting active from day one. A 30-day post-launch period covers conversion optimisation refinements based on real user behaviour data.

Our Diverse Development SolutionsOur Diverse Development SolutionsSince 2014
[01]Custom Web Applications
We architect and build bespoke web applications from first principles — SaaS platforms, multi-role operational dashboards, customer and vendor portals, ERP systems, booking engines, and data-intensive workflow tools. Every system is designed around your exact business logic and data model, not a template. Stack: React / Next.js frontend, Node.js or Python backend, PostgreSQL or MongoDB, deployed on AWS or GCP with CI/CD from day one.
[02]API & System Integrations
We design and implement secure, production-grade integration layers that connect your new application to your existing stack. Tally ERP, Salesforce CRM, Razorpay, WhatsApp Business API, Shiprocket, Google Workspace, Zoho, SAP — if it exposes a REST or GraphQL endpoint, we wire it in. We build middleware layers, webhook handlers, and real-time sync pipelines so your data flows without double entry or manual reconciliation.
[03]Cloud & DevOps Engineering
We provision, configure and manage right-sized cloud infrastructure on AWS, GCP or Azure — auto-scaling groups, managed databases (RDS, Cloud SQL, Atlas), CDN delivery, container orchestration with Docker and Kubernetes, and CI/CD pipelines via GitHub Actions or GitLab CI. Every environment ships with uptime monitoring, alerting, automated backups and a documented runbook. We target 99.9%+ uptime SLAs as a baseline, not a premium.
[04]Mobile & Cross-Platform Apps
We build React Native and Flutter applications that share the same backend APIs as your web platform — giving you iOS, Android and web coverage from a single, unified codebase. Features include offline support with local data sync, push notifications, biometric authentication, payment gateway integration, and submission to both the App Store and Google Play. One deployment pipeline, consistent data across every device.
[05]AI & Intelligent Automation
We build production-grade AI-powered applications: RAG pipelines over private document corpora, LLM-integrated workflow tools using the OpenAI and Anthropic APIs, agentic orchestration layers using MCP and n8n, and intelligent data extraction and classification systems. We do not bolt AI onto existing apps as a feature — we architect it as a core system component with proper context management, fallback logic, audit trails and cost controls.
[06]Legacy Modernisation & Audits
We take over underperforming, insecure or unmaintainable codebases and make them production-safe. Our audit process covers code quality, OWASP security vulnerabilities, performance bottlenecks, dependency staleness, database schema health and infrastructure risk. From there we stabilise, refactor and migrate — moving monoliths to modular architectures, upgrading stacks, replacing brittle third-party dependencies and restoring test coverage — so the codebase is ready for new features without accumulating further technical debt.
CASE STUDIES

eCommerce stores we have built
for brands in Noida & Delhi NCR

01D2C Brand

Custom eCommerce store for a Noida D2C skincare brand — product configurator, subscriptions, and loyalty

Checkout conversion rate improved from 1.8% (Shopify template) to 4.1% (custom build) within 3 months. Subscription revenue reached 28% of monthly GMV within 6 months of subscription launch. Repeat purchase rate improved from 22% to 41% after the loyalty programme launched. Average order value increased 34% after the product bundling configurator was introduced.

Problem

The brand was on a standard Shopify theme that could not support their product customisation workflow (customers selecting ingredients for personalised formulations), subscription orders, or a loyalty programme without multiple paid apps that conflicted with each other. Checkout was losing 60% of users at the payment step due to a non-UPI-optimised payment flow.

Solution

We built a custom eCommerce store with a product configurator for personalised formulations, subscription order management with pause and skip functionality, a loyalty programme with points earning and redemption at checkout, a UPI-first checkout with saved payment methods for returning customers, and an operations dashboard with subscription management and fulfilment tracking.

Stack

Next.js, Node.js, PostgreSQL, Razorpay, WhatsApp Business API, Redis, Shiprocket API

02B2B Wholesale

B2B wholesale portal for a Delhi NCR FMCG manufacturer supplying 800 distributors

Order processing time reduced from 3 days (phone order to dispatch) to same-day for 74% of orders after the portal replaced phone-based ordering. Order errors from miscommunication reduced to zero. The manufacturer's sales team could focus on acquiring new distributors rather than processing existing orders — new distributor onboarding increased 40% in the first quarter after portal launch.

Problem

The manufacturer took wholesale orders via phone calls from 800 distributors across North India. Each order was entered manually into the ERP by the sales team. Pricing was communicated verbally and frequently led to disputes. Distributors had no visibility into their order status, credit limit, or outstanding balance.

Solution

We built a B2B wholesale portal with distributor login, customer-specific pricing and product catalogues, credit limit visibility, PO-number-referenced checkout, order status tracking, outstanding balance and invoice download, and integration with the manufacturer's Tally ERP for order and payment records.

Stack

Next.js, Node.js, PostgreSQL, Razorpay, Tally integration, Puppeteer (invoices), SendGrid

03Omnichannel Retail

Unified eCommerce and POS system for a Gurugram fashion retailer with 4 stores and an online store

Inventory discrepancies between online and physical stores eliminated — stockouts on the website from items sold in-store reduced to zero after unified inventory was implemented. Click-and-collect (buy online, pick up in-store) accounted for 19% of online orders within 2 months. Online revenue grew 3.1x in 6 months as online customers who previously could not find accurate stock information gained confidence in availability.

Problem

The retailer operated 4 physical stores and a Shopify website with separate inventory systems. Items sold in-store were frequently still showing as available online, leading to order cancellations and customer complaints. There was no click-and-collect option. The retailer had no unified view of total sales across online and offline channels.

Solution

We built a unified retail platform with a shared inventory system that decremented stock across the relevant store and the website simultaneously regardless of where the sale occurred, a click-and-collect checkout option with store selection and pickup notification, an omnichannel sales dashboard showing online and offline revenue by channel and store, and a simplified in-store POS that connected to the unified inventory.

Stack

Next.js, Node.js, PostgreSQL, Razorpay, custom POS (React), inventory sync service, SendGrid, WhatsApp Business API

Custom Web App Development — Marketing Wise Noida

Top Rated Full StackSoftware Developers
in Noida, Delhi, NCR & India

Custom eCommerce development for D2C brands, B2B wholesale portals, and omnichannel retailers in Noida and Delhi NCR.

Marketing Wise builds custom eCommerce stores for brands and businesses in Noida and Delhi NCR — product catalogue, conversion-optimised checkout, UPI payment integration, order management, warehouse and courier integration, returns portal, loyalty programme, and analytics. Fifty stores delivered across D2C, B2B wholesale, and omnichannel retail.

How much does custom eCommerce development cost in India?

A focused D2C store with catalogue, checkout, payment gateway, and order management starts at ₹5 lakhs. Full eCommerce platforms with subscription management, loyalty programme, multi-warehouse inventory, multi-courier integration, B2B wholesale features, or marketplace seller management range from ₹10–25 lakhs depending on feature scope.

How long does eCommerce development take?

A focused D2C store takes 8–10 weeks. Full platforms with subscriptions, loyalty, multi-warehouse inventory, multi-courier integration, and a customer mobile app take 12–16 weeks. B2B wholesale portals with ERP integration take 12–14 weeks. Marketplace builds with seller onboarding and commission management take 14–18 weeks.

Can the store handle the traffic spike during a Big Billion Day-style sale?

Yes, with the right architecture. We build eCommerce on horizontally scalable infrastructure — additional server instances are provisioned automatically during traffic spikes and deprovisioned after. Product pages are CDN-cached so they load fast regardless of backend load. Inventory checks during checkout use Redis for sub-millisecond response. We recommend a load test simulating 5–10x normal traffic before every major sale event.

Can we migrate from Shopify to a custom store without losing SEO rankings?

Yes. We manage the SEO migration carefully — all existing product and collection URLs are preserved or 301-redirected to the new URLs, meta titles and descriptions are migrated, structured data (product schema) is implemented on the new store, and the sitemap is submitted to Google Search Console immediately after go-live. We monitor organic traffic for 4 weeks post-migration and address any unexpected drops promptly.

Can the store sell both in India and internationally with multi-currency pricing?

Yes. We build multi-currency eCommerce where international customers see prices in their local currency (converted at a configurable rate or live exchange rate), pay in their currency via international payment gateway (Stripe or Razorpay International), and receive duties and taxes information at checkout. Domestic Indian customers see INR pricing and Indian payment options. Inventory and order management are unified across geographies.
