Serving Kolkata, West Bengal
Software Development Company in Kolkata, West Bengal
CodeQuan Technologies Pvt. Ltd. is headquartered in Belgharia, Kolkata. We build websites, mobile apps, GST software, hospital ERPs, and custom solutions for Kolkata businesses — and beyond.
Why Kolkata Businesses Choose CodeQuan
Kolkata is our home city and the heart of our operations. We understand the rhythms of Kolkata's business landscape intimately — from the healthcare sector centred around hospitals on EM Bypass and Mukundapur, to the educational institutions in Salt Lake and New Town, to the trading enterprises on Burrabazar and Park Street. Our engineers have built hospital management systems for Kolkata clinics, school ERPs for institutions in South and North Kolkata, GST billing platforms for Kolkata manufacturers, and e-commerce stores for local D2C brands. Being headquartered in Belgharia means we can meet clients in person, attend site visits, and respond faster to Kolkata-based requirements than any remote agency can. Our team speaks English, Bengali, and Hindi — and understands the specific compliance, payment, and workflow requirements that Kolkata and West Bengal businesses face.
