Business in Kolkata
Eastern India’s largest commercial city
Kolkata has been eastern India’s trading capital for centuries. Burrabazar is one of the largest wholesale markets in Asia, and the city’s distributors supply shops across West Bengal, the North East, Bihar and Jharkhand.
Wholesalers here deal with high volumes, long credit and inter-state dispatches every day; retailers in New Market, Gariahat and the city’s neighbourhoods need fast billing; and chemists depend on wholesale markets like Bagri Market.
Burrabazar’s wholesalers deal in high volumes on long credit and dispatch goods across eastern India. Bill-wise dues, credit limits, transport details and e-way bills are daily essentials.
Milaan ERP keeps billing, stock, accounts and GST in one place, so a bill made at the counter is already in your books and your GST data. Most Kolkata businesses are set up within a few days, with our team helping online.

GST in West Bengal
GST for Kolkata businesses, done right
Businesses registered in West Bengal have GSTINs starting with 19. Sales to customers within West Bengal carry CGST and SGST; sales to Bihar, Jharkhand, Odisha, Assam and Sikkim or any other state carry IGST. Milaan ERP reads the customer’s state from their GSTIN or address and applies the right tax on every bill.
Durga Puja is the biggest shopping season of the year, followed by Diwali, Poila Baisakh and the wedding season. Distributors stock up well ahead of Puja. Since 22 September 2025, most goods are at 5% or 18% GST, so check that your item rates are up to date before the next busy season.
Tip: E-way bills are needed for inter-state movement of goods over ₹50,000. West Bengal may set its own limit for movement within the state, so check the current rule.
