# Required checkout fields

eCommerce allows you to make certain checkout fields required, such as PO Number. Required fields activate a server-side validation. It is useful to require the PO Number, for example, when pricing behavior can change between the time a user adds an item to their cart and the time they check out.

To manage required checkout fields in eCommerce:

1. From the top navigation bar, select your account.
2. From the dropdown menu, select **Commerce Administration**.
          Note

          

You must have the Commerce System Administrator [role](/v1/docs/user-roles) to access this menu item.
3. From the left navigation area, select **Screen Configuration**.
4. From the top navigation bar, select **Checkout Order**.
