Business in Purnea
The fast-growing trading hub of Seemanchal
Purnea is the main market town of the Seemanchal region, close to West Bengal and not far from Nepal. Its grain and agri markets, especially for maize and makhana, and its growing retail trade serve a wide surrounding area.
Being close to West Bengal means many Purnea businesses sell across state lines, so getting CGST, SGST and IGST right on every bill matters. Wholesale, grocery and medical stores make up a large part of local trade.
Purnea’s grain, maize and makhana traders deal in large quantities and sell to buyers in other states, especially West Bengal. Weight-based units and correct IGST on inter-state sales are essential.
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 Purnea businesses are set up within a few days, with our team helping online.

GST in Bihar
GST for Purnea businesses, done right
Businesses registered in Bihar have GSTINs starting with 10. Sales to customers within Bihar carry CGST and SGST; sales to West Bengal, Jharkhand and Uttar Pradesh 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.
Chhath, Diwali, Durga Puja and the wedding season are the busiest periods. Agri traders also follow the maize and makhana harvest cycles. 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. Bihar may set its own limit for movement within the state, so check the current rule.
