Devtechify · West Bengal
Software Development Company in Kolkata
Websites, custom software, AI agents, WhatsApp automation and billing tools for Kolkata businesses, built by Devtechify.
Burrabazar is probably the best place to see how Kolkata trades. Wholesalers sit in narrow lanes with godowns above, and goods go out to markets across eastern India on trust, long credit and memory. College Street's bookshops and the city's publishers, schools and tuition teachers form a world of their own, and film and television studios in Tollygunge keep the media crowd busy. Durga Puja decides the year's calendar for almost everyone.
A Burrabazar wholesaler could get stock and credit tracking, and Billy was built for that. A publisher could get a title-wise stock and distributor ledger.
What we build for Kolkata's businesses
Wholesalers, traders and distributors
Wholesalers in the old market lanes sell on long credit to buyers across eastern India, so the daily headache is knowing who owes what and for how long, and an ageing statement answers it.
Fast invoicing, party-wise receivables and payables, purchase bills, stock, and a daily dashboard of what is owed and what is due.
Read the guideSchools, colleges and coaching institutes
Tuition teachers, schools and coaching centres juggle many batches across a big city, and software takes over the registers with fee reminders, attendance and parent messages.
Admission enquiry forms, fee reminders and attendance alerts on WhatsApp, and custom management tools when a standard ERP does not fit.
Read the guideMedia, film and publishing houses
Publishers and booksellers carry thousands of titles with slow turnover, so deciding what to reprint or return is a guessing game, and title-wise stock and sales history takes the guesswork out.
Content sites that load fast, subscriber and enquiry handling, and invoicing for productions and campaigns.

Questions from Kolkata businesses
Does Devtechify have an office in Kolkata?
Our team is based in Bengaluru and works with clients across India remotely. For Kolkata projects we run the kickoff, weekly demos and reviews over video calls and WhatsApp, and we can plan an on-site visit when a workshop would genuinely help.
Can you build software for wholesale and trading in Kolkata?
Yes. For this kind of business we typically build: Fast invoicing, party-wise receivables and payables, purchase bills, stock, and a daily dashboard of what is owed and what is due. Wholesalers in the old market lanes sell on long credit to buyers across eastern India, so the daily headache is knowing who owes what and for how long, and an ageing statement answers it.
How much does a website or custom software cost for a business in Kolkata?
It depends on scope, not on the city. A simple business website is a small project, while custom software with logins, billing or integrations takes longer and costs more. We give a fixed scope and estimate after a short discovery call, and our guide on website and app costs explains what drives the number.
Do you offer WhatsApp automation and billing software for Kolkata businesses?
Yes. WA Getway is our WhatsApp platform for messaging, broadcasts, auto-replies and the official Meta Cloud API. Billy is our cloud billing and inventory software for invoices, POS, stock and dues. Both are live, and either can be customised for your business.
How do we get started with a project in Kolkata?
Fill in the short form on this page or message us on WhatsApp. We reply within one business day, set up a call, and send a clear plan with scope, timeline and price before any work begins.
