Web Application Development for India

Web Application Development, built around how India works

Indian businesses often run their operations on Tally, spreadsheets and WhatsApp groups, and outgrow that once branches, distributors or field staff multiply. A web application gives everyone one source of truth: a dealer ordering portal, a school or hospital management system, a field service dashboard or a booking platform. Nexzem designs and builds these from our office in Dehradun for clients across India.

We usually build with Next.js or React on the front end and Node.js, Python or Laravel on the backend, hosted on AWS or Azure regions in India. Server rendering and careful asset budgets keep pages fast on mid-range phones and 4G connections, which is how many of your users will open them.

Integrations Indian web apps need

Most business web apps in India connect to finance, payment and messaging systems. These are the integrations we plan for most often:

  • Tally and Zoho Books for accounting sync
  • GST e-invoicing through the Invoice Registration Portal and e-way bills, usually via a GST Suvidha Provider
  • UPI, cards and net banking through Razorpay, Cashfree or PayU
  • WhatsApp Business API and DLT-registered SMS for notifications
  • DigiLocker and the Account Aggregator framework for consented document and financial data

Performance on real Indian networks

We set budgets for Core Web Vitals and test on mid-range Android phones over throttled 4G, not just office broadband. Devanagari and other Indic fonts are large, so we subset them and load only the scripts each page needs. Hosting in AWS Mumbai or Hyderabad, or Azure's Indian regions, with a CDN in front keeps latency low across the country.

Government and enterprise compliance

Government portals follow GIGW for accessibility, usability and content, and usually need a security audit by a CERT-In empanelled auditor before going live. All organizations should plan for CERT-In's directions on incident reporting and log retention, and for DPDP consent and data rights. We design logging, retention and access controls with these in mind. This is general information, not legal advice.

What our web application development covers

Browser-based software for customers or staff: portals, dashboards and SaaS products built to scale securely.

    The data model, API design and clickable prototypes are agreed before sprint one begins.

    Iterative Build

    Two-week sprints deliver working features to staging, with code review and automated tests on each change.

  4. 04

    Security and Load Testing

Web Application Development in India, answered

Something else on your mind? Ask a consultant and get a reply within one business day.

Can you integrate our web app with Tally?

Yes. Depending on your Tally setup, we sync masters, vouchers and invoices through Tally's XML interface or a connector, so orders and payments recorded in the web app flow into your books without re-entry. We test sync with your accountant's chart of accounts before go-live.

Do you build government portals that follow GIGW?

We design and build to GIGW and WCAG accessibility criteria, including bilingual content, accessible forms and screen reader support, and prepare the application for third-party security audits. Tender and empanelment requirements vary, so we review your specific RFP conditions at the start.

Where will our web application be hosted?

Usually in an Indian cloud region on AWS, Azure or Google Cloud, which keeps latency low and simplifies data localization for payments and other regulated data. Government projects may require MeitY-empanelled cloud services. We set up hosting under your company's account so you keep control.
