Website & App Development in Kolkata
Websites, mobile apps and custom software for Kolkata's traders, publishers, clinics, institutions and young companies, with Bengali typography done properly.
Kolkata is the largest city in eastern India, with about 4.5 million people in the 2011 Census and many more across the wider metropolitan area. It has old wholesale markets, a large port, a long publishing tradition and a growing set of IT and service firms.
Choosing a development partner from another city is a normal decision now. NioDelta is a software studio in Pune, Nashik and Mumbai. We work with Kolkata clients on calls and shared screens, then give a written scope and a fixed quote. We have no Kolkata office and will not pretend otherwise.
Where Kolkata businesses typically need software
Wholesale, retail and trade
Long-established markets handle textiles, stationery, hardware and food in large volumes. Dealer catalogues, WhatsApp order flows and GST-ready billing tools help traders handle repeat customers without writing everything down by hand.
Publishing, education and culture
Books, coaching, music and arts have deep roots in the city. Online storefronts for books or courses, event ticketing pages and student portals each meet a clear need, and Bengali-language interfaces matter.
Healthcare, services and startups
Clinics and diagnostic centres draw patients from across eastern India. Appointment booking, report delivery and follow-up reminders matter, as do dashboards and internal tools for service companies and startups in areas like Salt Lake and New Town.

Kolkata questions
Can you build a website in Bengali?
Yes, with caveats. We choose appropriate Bengali fonts, check conjunct characters render correctly across devices and set up the layout for longer text. We do not have in-house Bengali staff, so we recommend a native-speaker review of the copy before launch. Share a few reference sites in Bengali you like, and we will match the style.
Why choose a Pune studio over a Kolkata agency?
The decision should rest on fit, not distance. We work in IST with the same hours, communicate by call and WhatsApp, and share progress frequently. If you strongly want face-to-face meetings every week, a local firm may suit you better. Our working hours match yours, so calls are easy to schedule.
Do you handle GST and invoicing for a West Bengal company?
Yes. Our invoices include GST, and we can support GST-ready billing in the software we build for you. For compliance questions about your own filings, please consult your chartered accountant, as we do not give tax advice. We can issue a clear invoice that your accountant can book directly.
