How do I link an existing deposit account to my eCO account?
“You may link an existing deposit account to an Organization account in eCO and then charge fees against the balance of the deposit account any time you use eCO to register claims. To create an Organization account in eCO, click the Organization/DA link in the menu bar on the right side of the Welcome screen.”
