Hi elissakoornneef-,
Welcome to the Community and thanks for reaching out to us here. I'd be happy to share some information on starting over with your QuickBooks Online account.
QuickBooks understands that sometimes you may need to clear your data and start over. For this reason, you can purge your company data, as long as your account is less than 60-days old. Please keep in mind that this will remove all data in your company file and it cannot be restored. Here's a helpful guide for purging company data in QuickBooks Online.
If you would like personal assistance with the process, please don't hesitate to contact us. It would be our pleasure to work with you directly, and ensure you're able to start over with ease.
Schedule a Callback or start a Chat: click (?) Help in the upper right in QuickBooks Online > enter "Contact support" > hit Contact Us > provide a brief summary of your situation > hit Let's Talk > choose Get a callback or Start a Chat.
Social Media: Facebook, Twitter, and Instagram.
Support hours are from Monday to Friday between 9 a.m. and 8 p.m. ET.
Feel free to reach out again, if any other questions come to mind. We're always happy to help!
