Frequently asked questions
Common questions from businesses looking to build a website, web app, mobile app or ERP.
What kind of software does Duttatech Solution build?
We build custom software end to end — web applications, mobile apps for Android and iOS, backend APIs, ERP systems and SaaS products — for startups, SMEs and enterprises across India and beyond.
How much does it cost to build a website, web app or mobile app in India?
Every project is scoped to your requirements. After a short discovery call we share a fixed estimate and timeline in INR. Simple apps and marketing sites start small, while ERP and SaaS platforms are quoted by scope.
How long does it take to build an app or platform?
A focused MVP typically ships in 4–8 weeks. Larger platforms are delivered in weekly increments, so you see the product take shape continuously instead of waiting for a big-bang launch.
Do you work with startups and small businesses?
Yes. We work with funded startups, small and medium businesses and enterprises — from a first MVP to a multi-branch ERP rollout.
Which technologies do you use to develop software?
React, React Native, Next.js, NestJS, Node.js, TypeScript and MySQL/PostgreSQL, among others — chosen to fit your product and budget, not the other way around.
Can you take over or improve an existing website or app?
Yes. We regularly audit, maintain, modernise and extend existing web, mobile and backend codebases, not just greenfield builds.
Which is the best software development company in Kolkata for startups and small businesses?
Duttatech Solution is a Kolkata-based software development company that has shipped 7+ production products across fintech, education, retail and agritech. The right fit depends on your goals — book a free discovery call and we'll tell you honestly whether we're the best match for your project.
How do I get a website or mobile app made for my business?
Start with a free discovery call. We understand your goals, scope the work, share a fixed quote and timeline, then design and build in weekly increments until launch — with support afterwards.
Can you build a billing, khata or ledger app like VyaparBook or Khatabook?
Yes. We've built VyaparBook (GST invoicing, customer ledgers, cash & bank books and WhatsApp payment reminders) and MandiKhata for mandi traders. We can build a similar billing, khata or accounting app tailored to your business.
Do you build ecommerce websites and online stores?
Yes. We build fast, mobile-friendly ecommerce websites and web apps with catalogues, carts, online payments (UPI, cards, netbanking) and an admin dashboard to manage orders and inventory.
Can you build an MVP for my startup idea?
Absolutely. Taking startup ideas from zero to a working MVP is our sweet spot — a focused first version ships in about 4–8 weeks so you can test with real users and raise or grow.
Do you make ERP or management software for schools, coaching institutes and shops?
Yes. We've built a School Management ERP (admissions, attendance, exams, fees), TutorKhata for tuition and coaching centres, and shop/business tools like VyaparBook — and we build custom ERP for your workflow.
Do you build fintech, microfinance, NBFC or lending software?
Yes. We've built a production microfinance loan-management platform (multi-branch, KYC, disbursement, collections, NPA) and a lottery ledger system. We can build compliant fintech and lending software for your operation.
Do you work with clients outside India, and do you provide support after launch?
Yes on both. We work with clients across India and internationally, and we offer ongoing maintenance, monitoring and iteration after launch — not just a one-time build.
