To reset your sandbox account, click on your E-mail in the right corner and go to "Account > Administration" and press the "Clear Data"-button. In the popup-window you can choose between "Delete all customers and contracts related data" and "Delete all products, customers and contracts related data". Regarding your selection, the desired datas are deleted and you can start testing with a fresh sandbox account. If you want to delete your Sandbox account, please contact the support by mail support@billwerk.com.
