Who can assist me to delete all accounting transactions I HAVE MADE IN quickbooks online

If you are using QBO Simple Start or your account > 90 days old, you won't be able to purge your account. Cancel it and open a new blank one instead.

Hi there, @pierre-boujerdaa. I'd be happy to help you get a fresh start.

What specific reason you're considering QuickBooks Online? QBO will be the ideal choice for most small businesses. It's a cloud-based software that you can access anywhere with an internet connection. 

If your account is less than 90 days old, you have the option to delete all your data and start from scratch. Fiat Lux - ASIA is right. This option is only available to QuickBooks Online (QBO) Plus or Essentials users. If you're using QBO Simple Start, you have to cancel it or start a new one.

Here's how to purge your company:

1. Log in to your QuickBooks Online company.
2. Look at the URL in your browser's address bar. Delete all the text after the last / and enter purgecompany.
3. To confirm you want to delete your company data, type Yes.
4. Click OK.
5. Select Wipe data.

If you don't have this option, you cancel your current account and create a new one instead. Otherwise, you'll have to void or delete all your transactions manually.

Don’t hesitate to post a comment below if you need more help getting started with QBO, @pierre-boujerdaa. I'm always available for help at any time. Have a great day.
