How can I delete my testdata on the sandbox?
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.
