ECOB2B - E-Commerce Operator Business to Business Transactions
ECO B2B, or E-Commerce Operator for Business-to-Business transactions, refers to a framework where an e-commerce platform facilitates the supply of goods or services between businesses under GST regulations. The operator is responsible for collecting and reporting tax on supplies made via their platform under Section 9(5) of the CGST Act. Businesses must provide accurate details, including recipient GSTIN, document details, taxable value, tax rate, and place of supply, ensuring compliance. ECO B2B simplifies tax reporting, streamlines transactions, and reduces compliance risks, ensuring transparency and efficiency in inter-business e-commerce operations.
