What are you trying to build in Kolkata?

Five things Kolkata businesses hire us for, each with fixed scope, a real timeline, and a price you see before you commit.

Most common here: SMB and MSME · Hospitality · Jute and textile

Hospital & clinic website design

hospital website design in Kolkata · clinic website with online appointment booking · doctor website design4–6 weeks

More than three-quarters of patients search before they book. If your doctor list is a PDF and your appointment form lands in a Gmail inbox, they book at the hospital whose page loaded first.

Doctor and department pages that rank on their own for "cardiologist in Kolkata"
Online appointment and OPD booking, confirmed on WhatsApp
NABH, ABDM and ABHA-ready structure, with HIS or HMS integration
Hindi and English, fast on a low-end Android phone over 4G
Local SEO for Google Business Profile, maps and "near me" searches
Lab reports and teleconsultation flows when you need them

Online store, Shopify & ecommerce development

Shopify store development cost in India · ecommerce website development company Kolkata · Shopify migration3–8 weeks

You do not need a marketplace. You need a store that takes UPI, prints a GST invoice, and does not drop the cart on a patchy 4G connection.

Shopify or headless Next.js — we tell you which is cheaper for your catalogue
UPI, Razorpay, Cashfree, COD, GST invoices and automated e-way bills
Shiprocket, Delhivery and Blue Dart shipping, with live tracking
Product pages built to rank, with schema, reviews and fast image delivery
Migration from Wix, WooCommerce or Magento without losing rankings
Abandoned-cart and WhatsApp recovery flows that pay for themselves

We built Startus Cloud.

School, college & coaching websites

school website development company Kolkata · online admission form for school · coaching institute website design4–6 weeks

Admission season is eight weeks long. A school site pays for itself if it turns parent traffic into enquiries inside those eight weeks — the rest of the year it is a noticeboard.

Admission enquiry funnel a parent can finish on a phone in two minutes
Online fee payment and parent login — Razorpay, Cashfree, PayU
School ERP integration — Vidyalaya, Entab, Camu, Edumarc
Notices, results, gallery and circulars your office updates, not us
CBSE and ICSE mandatory disclosure pages, done properly
Hindi-first content where the parent audience is non-English-speaking

SaaS platforms & MVPs — an idea turned into a product

SaaS development company India · MVP development company · turn my idea into an app · custom software development Kolkata8–12 weeks

You have the idea and no technical co-founder. What you need first is a scope you can afford and a working v1 in front of real users — not a 200-page requirements document.

Two-week scoping sprint — clickable prototype, fixed scope, fixed price, before you commit to a build
Multi-tenant SaaS architecture — organisations, roles, permissions and per-tenant data isolation
Subscription billing and usage limits — Stripe, Razorpay Subscriptions, trials, invoices, dunning
Web app, mobile app or both — Next.js, React Native, Flutter, Node and Postgres on AWS or Vercel
Admin dashboards, analytics and audit logs — the unglamorous parts that eat a budget
You own the code, the repo and the cloud account from day one — no lock-in, ever

We built Campus Host and Aarogya Patient Management.

AI integration, chatbots & automation

AI development company in Kolkata · AI chatbot development · AI integration services · WhatsApp bot for business3–8 weeks

Most "AI" quotes are a chat widget bolted onto a website. What actually moves a number is AI wired into the work your team already repeats every day — answering the same questions, retyping the same data, chasing the same leads.

Support and sales chatbots trained on your own content — RAG, embeddings and vector search, so answers come from your documents, not a guess
WhatsApp Business bots and voice agents that capture leads and write straight into your CRM
Claude and GPT built into the product you already run — search, summaries, drafting, classification
Back-office automation — quotes, invoices, reports, data entry and document extraction
Guardrails, evaluation and cost controls, so the answers stay accurate and the monthly bill stays predictable
Bilingual AI — Hindi and English, for teams and customers who switch between them

Why us, here

Why a senior remote team for Kolkata businesses

Kolkata's agency density is lower than Mumbai, Delhi, or Bangalore, which means businesses either overpay for imported metro agency rates or settle for freelance work that underdelivers. We fill the gap: senior engineers, modern stack, honest INR pricing, without the Bandra or Koramangala markup.

Talk to an engineer

Metro-grade engineering for Kolkata's underserved SMB market

Kolkata has Eastern India's deepest SMB and MSME density — manufacturing units, export houses, hospitality brands, retail chains, healthcare groups, and education institutions — but proportionally fewer senior web engineering teams than Mumbai or Bangalore. Most Kolkata businesses either work with local freelancers delivering WordPress plugin stacks, or pay Mumbai/Delhi agencies 40–60% premiums for remote delivery anyway. We remove the Mumbai middleman: senior engineers, Next.js and TypeScript, Lighthouse 95+, transparent INR billing, and a delivery model built for Kolkata's IST business hours. For SMBs and MSMEs spending ₹1.5L–₹8L$1.8k – $9.5k USD on a web build, quality consistency and post-launch accountability matter more than agency city.

Performance and credibility for export and hospitality verticals

Kolkata's jute exporters, tea estate owners, and heritage hospitality properties face a specific problem: buyers and guests from Germany, the UK, and Japan judge credibility by the website before they respond to any inquiry. A slow site with poor mobile experience signals operational immaturity to exactly the stakeholders you cannot afford to lose. Every Vellumarc build targets Lighthouse 95+ across Performance, Accessibility, and SEO. We optimize for both high-speed fiber (European buyers on desktop) and 4G Android (domestic hospitality and retail users). For Kolkata export businesses, we also configure structured data markup, hreflang for multilingual buyer audiences, and INR/USD/EUR multi-currency presentation where relevant.

Async-first for Salt Lake IT firms and export businesses with global ties

Salt Lake Sector V and New Town IT firms manage US and European clients as standard.

Kolkata's jute, tea, and leather export houses deal with buyers across Germany, Japan, and the UK. Our async-first model — Loom walkthroughs, Notion briefs, Slack with same-business-day response, milestone-based billing — maps directly to how Kolkata export and IT businesses already manage overseas relationships. We accept USD invoicing for Kolkata firms billing international clients and align sprint demos to EST or CET windows on request. Remote-first is not a compromise; for businesses already running distributed client relationships, it is the efficient default.

Frequently Asked Questions

How much does a website cost for a Kolkata business?

A professional marketing or service site for a Kolkata hospital, education institution, or mid-size export business runs ₹1.5L–₹4L$1.8k–$4.8k, delivered in 4–6 weeks. For hospitality businesses — boutique hotels, heritage properties, or event venues — the same range applies with heavier investment in visual storytelling, online booking integration (Beds24, Staah, or direct), and restaurant or package showcase pages. Jute and tea export B2B sites with product catalogs, inquiry forms, certification documentation, and multi-currency pricing typically run ₹4L–₹12L$4.8k–$14.5k depending on catalog depth and integration requirements. Custom SaaS products for Salt Lake IT firms or internal tools for manufacturing groups sit in the ₹15L–₹65L$18k–$80k USD band. Every quote is itemized in INR with milestone billing — no discovery retainers, no surprise charges at launch.

What do Kolkata web agencies charge, and where does Vellumarc fit?

Kolkata's agency market is thinner than other metros, which creates a specific dynamic: the few established agencies charge Mumbai-level rates because demand exceeds local supply, while the large freelance pool in Salt Lake and New Town undercuts on price but delivers inconsistently. Established Kolkata agencies typically quote ₹5L–₹25L$6k–$30k for marketing sites and ₹30L–₹1Cr$35k–$100k for product builds — pricing calibrated to large corporate clients, not MSMEs or export houses. Freelancers at ₹20k–₹1.5L$250–$2k USD deliver quickly but rarely with scalable architecture, proper SEO foundations, or post-launch accountability. We price at the senior quality tier — Lighthouse 95+, TypeScript, proper CI/CD — but 25–40% below what Kolkata's established agencies charge, because we are remote-first and do not carry the commercial real estate overhead of a Park Street or Camac Street address.

Should I hire a Kolkata agency locally or work with a remote team?

Kolkata has genuine local talent but it is concentrated in large IT services firms and freelance networks, with fewer mid-tier agencies that combine senior engineering with practical SMB pricing. The strongest argument for a local agency is in-person trust and cultural familiarity — both real advantages. We address them directly: we visit Kolkata for project kickoffs and major reviews when the project size warrants it, and we have clients across Siliguri, Durgapur, and Asansol on the same remote model. The strongest argument for going remote is access to senior engineers who would not take a full-time role at a Kolkata agency salary — they work with us because of the project quality and flexibility. For Kolkata export businesses that already manage UK and German buyers remotely, the remote-first vendor model is familiar. Communication structure — written briefs, recorded walkthroughs, Notion decision logs — provides more accountability than proximity.

Do you build websites for jute exporters and tea businesses in Kolkata?

Yes. Kolkata's jute and tea export ecosystem is one of the most internationally connected trade verticals in India, and the web infrastructure has often not kept pace with buyer expectations. For jute exporters in Howrah and Rajabazar, we build B2B catalog sites with graded product listings (yarn count, jute quality grades, certifications), RFQ and sample-request flows, multi-currency pricing, and documentation pages for buyer due diligence — REACH compliance statements, phytosanitary certificates, and quality audit summaries that German and Dutch buyers require before placing orders. For Darjeeling and Assam tea estate brands with Kolkata offices, we build estate storytelling sites with first-flush and second-flush seasonal catalog pages, direct-to-buyer wholesale inquiry forms, and export documentation. Structured data markup ensures Google indexes product details for buyer searches in English, German, and Japanese — the key buyer languages for these verticals.

How do you handle project communication for Kolkata clients?

We work IST as primary timezone, which means Kolkata clients get same-business-day response as the default. Async-first delivery — Loom video walkthroughs for design and code reviews, Notion structured briefs, Slack threads for quick questions — means you receive clearer communication than a weekly in-person meeting provides, with a written record of every decision. We do not mandate sync calls; they are available on request for complex design or scope discussions. For Salt Lake Sector V IT firms with US or European client relationships, our workflow maps directly to the distributed-team model you already operate. For Kolkata export businesses managing trade inquiries from Germany or Japan, we align review-ready deliverables to CET or JST business hours when needed. Kolkata clients are generally more comfortable with structured written communication than they expect — it reduces the rework from verbal misalignment.

What does hosting and maintenance look like for Kolkata businesses after launch?

Standard Next.js builds deploy on Vercel — global CDN, automatic HTTPS, preview deployments per pull request, sub-100ms TTFB from Indian edge nodes. Heavier backends or data-sensitive builds (healthcare, fintech) deploy on AWS Mumbai region with proper IAM configuration and encrypted storage. For Kolkata hospitality businesses with booking engine integrations, we configure uptime monitoring with immediate alerting — booking engine downtime during peak season is a direct revenue loss, not just an inconvenience. Post-launch monthly retainers cover dependency and security updates, uptime monitoring, and a fixed allocation of content and feature change hours. Retainer pricing starts at ₹9,000$160 USD/month for standard Next.js sites. For jute and tea export businesses that update product catalogs seasonally — first-flush in March, second-flush in May, new grade listings for the Kolkata Tea Auction — we scope content update allocations into the retainer so seasonal updates ship on time without a separate project engagement.

Are you based in Kolkata?

No. We're headquartered in Raebareli, not on Park Street or in Salt Lake Sector V. We're an India-based, remote-first team — not an outsourced Mumbai or Delhi middleman either — which is how we hold senior-tier engineering quality at 25–40% below what Kolkata's established agencies charge.

Can I meet the team in Kolkata?

Yes, for kickoffs and major reviews — Park Street, Salt Lake, Howrah, wherever suits you — when the project size makes the trip worthwhile. We also work with clients across Siliguri, Durgapur, and Asansol on the same remote-first model, with structured written communication (Notion decision logs, recorded walkthroughs) doing most of the trust-building day to day.
