Why Chandni Chowk businesses are investing in custom e-commerce platforms

Chandni Chowk is a neighborhood of delhi in old delhi, india, and one of the markets in Delhi, India where we build custom e-commerce platforms.

Historic wholesale market — a business base that increasingly wants to sell online rather than through calls, messages and spreadsheets.

Across Delhi, the economy is shaped by government, wholesale trade (Chandni Chowk, Sadar Bazar), services, startups and one of India's richest consumer markets, with New Delhi as the state capital.

India has more than 6 crore (60 million) MSMEs registered on the Udyam portal (Ministry of MSME). India has the world's largest real-time payments system in UPI and one of the fastest-growing online shopper bases, increasingly from tier-2 and tier-3 cities. Businesses that own their store — with UPI, COD, regional languages and WhatsApp updates — build loyal customers instead of renting them from marketplaces.

For a business in Chandni Chowk, the opportunity is to own the customer relationship: your own custom e-commerce platform keeps your margin, your data and your brand, while marketplaces and social channels become additional sales routes instead of the only one.

Localised for Chandni Chowk, not translated into it

Conversion in Chandni Chowk depends on small local signals — the right currency, the right words and the right payment and courier names.

Currency and pricing

The store speaks Indian rupee: INR amounts from product page to invoice, so Chandni Chowk buyers never convert in their heads.

Language and content

We localise pages, emails and notifications into Hindi, English and Punjabi where your audience needs it.

Local trust signals

We add the payment logos, courier names and policy pages shoppers in Chandni Chowk recognise: UPI (Google Pay, PhonePe, Paytm) and RuPay, Visa and Mastercard cards and delivery through Delhivery.

Domain, phone and contact

A .in domain (or your own) builds local trust and search relevance. Contact buttons are pre-set with +91, so a customer in Chandni Chowk taps once to call or message.

Designed to your requirements, not a template

Every NNT Mart custom e-commerce platform in Chandni Chowk is engineered to the client's own brief — the web platform, the admin panel and, when you need one, a mobile application built for your workflow.

In Chandni Chowk we typically work with enterprises with complex catalogues, multi-brand groups, businesses outgrowing SaaS platforms and companies migrating legacy stores, and with sellers in categories such as mobiles and electronics, fashion and ethnic wear, beauty and personal care and groceries and FMCG that have strong online demand across India.

We start with a requirements meeting, show you a working demo within 24 hours, and only then propose scope, milestones and budget.

What your custom e-commerce platform includes

Each module below is configured — or custom-developed — to your requirements. You choose what launches first and what follows in later phases.

Custom workflows

Product configurators, made-to-order flows, approvals, contracts and industry-specific rules. Shipping rules can use Delhivery, Blue Dart and Shiprocket as well as your own delivery staff in Chandni Chowk.

Headless architecture

API-first commerce with a fast front end, so web, app, kiosk and marketplace channels share one backend. Multiple stock points in Delhi are supported, so a Chandni Chowk order ships from the nearest one.

Multi-entity operations

Multiple brands, companies, warehouses, currencies and tax registrations on one platform. Reports show which products, customers and areas of Chandni Chowk drive revenue.

Deep integrations

ERP, PIM, WMS, CRM, POS, accounting and legacy systems with reliable, monitored data sync. Pages, search filters and wording are tuned to how people in Chandni Chowk look for products, in Hindi and English if your audience needs it.

Migration

Move from older platforms with product, customer and order history, SEO-safe redirects and parallel runs. Bulk import and sync tools mean the Chandni Chowk team never re-keys stock, prices or descriptions by hand.

Performance and security

Caching, CDN, load testing, security hardening, audit logs and cloud infrastructure as code. Payment steps are built around UPI (Google Pay, PhonePe, Paytm), RuPay, Visa and Mastercard cards and net banking, the options shoppers here already trust.

Getting paid online in Chandni Chowk

Shoppers in Chandni Chowk rarely abandon a cart over price alone — they leave when their usual method is missing. Here that means UPI (Google Pay, PhonePe, Paytm), RuPay, Visa and Mastercard cards and net banking, then cash on delivery, EMI and cardless EMI and wallets and UPI AutoPay for subscriptions.

Provider approval, settlement time and fees differ by business type, so we shortlist gateways with you, then wire up status updates, refunds and reconciliation in INR with GST invoices — card details stay with the provider.

  • RuPay, Visa and Mastercard cards
  • Net banking
  • Cash on delivery
  • UPI (Google Pay, PhonePe, Paytm)
  • Wallets and UPI AutoPay for subscriptions
  • EMI and cardless EMI

Shipping, couriers and local delivery in Chandni Chowk

Your custom e-commerce platform can book shipments and share tracking with Delhivery, Blue Dart, Shiprocket, DTDC, Xpressbees, Ecom Express and India Post, or route orders to your own riders and stores across Chandni Chowk.

We set up shipping zones, cut-off times, free-shipping thresholds, cash-collection rules and returns so the promise on the product page matches what your team can deliver.

Selling online legally in Delhi

India levies GST, rationalised in September 2025 into main slabs of 5% and 18% with a 40% rate for select goods; e-commerce operators collect TCS, and e-invoicing and e-way bills apply above set thresholds.

Businesses registered in Delhi carry GST state code 07 in their GSTIN, and intra-state sales are billed as CGST + SGST while sales to other states are billed as IGST.

On privacy we design around the Digital Personal Data Protection Act 2023 and the DPDP Rules 2025, alongside the IT Act 2000; on consumer rights the store reflects the Consumer Protection (E-Commerce) Rules 2020, which require seller details, country of origin, grievance officers and clear return and refund policies, plus the Legal Metrology rules on product labelling.

Controls we implement include compliant invoices, consent capture, policy pages, restricted staff access and audit trails. Please confirm the final legal and tax position with a local adviser in Chandni Chowk.

Owning your channel in India

Selling in Chandni Chowk through Amazon.in, Flipkart and Meesho gets you reach quickly, yet the buyer belongs to the platform, not to you.

NNT Mart gives you a channel you own: your domain, your customer list, your pricing and your brand. Where it helps, we connect product feeds and orders from marketplaces so stock stays in sync and your team works from one dashboard.

Industries in Chandni Chowk we work with

Popular online categories in India include mobiles and electronics, fashion and ethnic wear, beauty and personal care, groceries and FMCG, home and kitchen and B2B industrial supplies. Historic wholesale market — which shapes what local businesses need online. In Chandni Chowk, we most often build custom e-commerce platforms for:

Enterprises with complex catalogues

We map how enterprises with complex catalogues sell today and digitise it end to end — from enquiry and order to payment, dispatch and repeat purchase.

Multi-brand groups

For multi-brand groups, we usually start with multi-entity operations, then add PIM and DAM once orders are flowing.

Businesses outgrowing SaaS platforms

Catalogue, pricing and fulfilment rules designed for businesses outgrowing SaaS platforms in Chandni Chowk, connected to the systems you already use.

Companies migrating legacy stores

Companies migrating legacy stores get deep integrations plus performance and security workflows tailored to their operations.

Regulated sectors

We map how regulated sectors sell today and digitise it end to end — from enquiry and order to payment, dispatch and repeat purchase.

High-traffic retailers

For high-traffic retailers, we usually start with custom workflows, then add identity and SSO once orders are flowing.

Android and iOS apps for your Chandni Chowk business

In Chandni Chowk, shoppers browse on phones first. Because the platform is API-first, customer, staff and partner mobile apps can be added at any point without rebuilding the backend.

Apps are published under your own developer accounts and share the same backend as your custom e-commerce platform, so offers, stock and orders are always consistent between web and mobile.

Order alerts, offers and abandoned-cart reminders go out on Chandni Chowk time (UTC+5:30), in Hindi and English if you want.

  • Search engines (Elasticsearch, Algolia)
  • POS and store systems
  • WMS and 3PL systems
  • PIM and DAM
  • Identity and SSO
  • BI and data warehouses
  • Cloud platforms (AWS, Azure, GCP)
  • SAP, Oracle, Microsoft Dynamics and Odoo ERPs

Integrations above are examples; we connect any system that offers a suitable API, database access or approved import and export process.

We work in English and can deliver storefront content in Hindi, English and Punjabi. NDAs are signed on request, and you get a named project lead plus direct access to the engineers building your custom e-commerce platform.

Our head office is in Chhapi, Gujarat, with an office in Hyderabad and representation in Nigeria, South Africa, Ethiopia and Zambia; Chandni Chowk clients are served remotely with on-site workshops when the project needs them.
