# What is the purpose of the e-Commerce Operator field in invoices?

If you’re selling items to your customers through e-commerce websites, the e-commerce details can be added in the E-Commerce Operator field. The associated details will be reflected under the _Supplies through ECO_ section of the **GSTR-1** report and under _3.1.1 Details of supplies notified under sub-section (5) of section 9 of the Central Goods and Services Tax Act_ of the **GSTR-3B**.

The E-Commerce Operator field can be enabled by following these steps:

*   Navigate to _Settings_ at the top right corner of the page.
*   Select **Invoices** under _Sales_.
*   Go to _Field Customization_ and place the cursor near _E-commerce Operator_.
*   Click the down arrow next to the _status_ tab and choose **Mark as Active**.
