App & website development · Kolkata, West Bengal
Apps and websites for Kolkata traders, sweet shops and five days of Puja.
Customer apps, partner apps, dashboards and websites in Bengali and Hindi, designed and built by one team in Bengaluru, working with Kolkata businesses remotely. You keep running the business; we take the brand, design and tech.
The market
Doing business in Kolkata.
Kolkata is a trading city. Burrabazar's wholesale lanes move textiles, spices and dry goods to the whole of eastern India, much of it still on paper ledgers and phone calls. Tea and jute have been traded here for generations, and family businesses tend to be old, trusted and careful with change.
It is also a city that shops and celebrates in its own way. Sweet shops with a loyal neighbourhood following, Park Street restaurants, book lovers on College Street, and Durga Puja, when pandals draw crowds for days and organisers juggle sponsors, volunteers and visitor flow.
We work with Kolkata businesses remotely and design for Bengali from the start, not as a translation added at the end.
What Kolkata businesses ask for
Built around how Kolkata works.
The products local businesses come to us for most, and the reason each one matters here.
- 01
Wholesale ordering and credit
Burrabazar traders run on credit and repeat orders. A simple ordering app with a credit ledger replaces the phone call and the notebook.
- 02
Sweet shops that ship
Mishti travels to family abroad and across India. A store with pre-orders, festive boxes and delivery dates handles the gifting rush.
- 03
Puja and event management
Pandal committees handle passes, sponsors, volunteers and crowd timings. Event tools built for crowds, like our Outpass build, fit well.
- 04
Billing for counter shops
GST invoices, a customer khata and stock in one place, in Bengali for the person at the counter.
Proof, not promises
Builds closest to Kolkata’s market.

What we can build for you
Apps Kolkata already needs.
Each page covers the apps involved, the features Indian customers expect, and what moves the cost and timeline.
- 8–12 weeksGST billing app →A kirana at 7 pm has no time for a slow screen. We build billing apps that print a GST invoice in seconds, keep the customer credit book honest, and tally cash and UPI at closing — for one shop or a chain.
- 6–8 weeksEcommerce website →A template store looks like every other store. We design and build D2C storefronts with a real brand system, fast product pages, checkout that suits Indian buyers, and the back-office screens your team uses to ship.
- 8–12 weeksEvent & ticketing app →Concerts, comedy nights, restaurant tables and five-day weddings. We build the booking app, the scanner at the gate and the dashboard for venues and vendors — all on one live data clock.
- 4–6 weeksRestaurant website and QR ordering →Your regulars shouldn't have to go through an aggregator to reach you. We build restaurant and bakery websites with reservations and direct orders, plus QR table ordering, bill splitting by UPI and a kitchen screen that keeps courses in order.
- 8–12 weeksLogistics app →Booking a truck should be as easy as booking a ride, and the ops team behind it needs a screen that can handle thousands of shipments without slowing down. We build both: the booking and driver apps, and the dense dashboards that run the fleet.

Questions from Kolkata
Asked and answered.
Can the app be in Bengali?
Yes. We design every screen to hold Bengali script cleanly, test it with real phrases rather than placeholder text, and keep all wording in translation files your team can edit. For counter staff and delivery partners, Bengali first often matters more than for customers, so we usually start there.
Our business still runs on ledgers. Is an app too big a jump?
Not if it starts small. We often begin with one thing that already hurts — taking repeat orders, tracking credit or sending bills — and make that easier than the notebook. Once your team trusts it, more can move across. Our Tillbook build shows what a simple billing and khata app looks like.
Do you work with Kolkata clients remotely?
Yes. Our studio is in Bengaluru and we work with Kolkata teams remotely: a kick-off call, a shared board, and a weekly demo link you can open on any phone. You see working screens from the first fortnight, so you can show family partners or staff and get their view early.
Who owns the code and designs?
You do. Source code, design files and brand assets are handed over in full, in repositories and tools your team can keep using.
