ECOA - E-Commerce Operator – Assessed
ECOA in GSTR-1 typically relates to the scenario where the e-commerce operator is required to report the taxable supplies made by the sellers or suppliers (businesses) on their platform. The operator may also need to report on reverse charge transactions (e.g., where the e-commerce operator is responsible for collecting and remitting tax on behalf of the sellers).
