Only the admin user can close an Adyen account.
Log in to the Customer Area using your live credentials, and go to Account > Close account. On this page, choose the date that you would like to close the account. You will be unable to process transactions from this date.
After you close your account, you will be able to access your Customer Area for six months. During this period you can still:
- Defend chargebacks
- View and download reports
- Process refunds
Your deposit will be released six months after the last transaction. This is because chargebacks can still occur in this period.
