I want to completely reset my account, delete all clients, delete all payments, delete all invoices, delete all linked cards, delete all rules. and completely start new

Welcome to the Community, @manuel-ugarte-ic. I can guide you on how to reset your account and start a fresh file.

Yes, you can take the suggestion provided by Fiat Lux - ASIA to reset your account. If your book is less than 60 days old, you can delete everything by purging your data. Here's how:

1. Sign in to your QuickBooks Online (QBO) account as an admin.
2. In the URL or address bar, delete all the text after the last / and enter purgecompany.
   • Before: https://…qbo.intuit.com/app/homepage
   • After: https://…qbo.intuit.com/app/purgecompany
3. Enter Yes in the confirmation message.
4. Hit OK, then Wipe data.

But if you're online company is older than 60 days, wiping out isn't possible. Thus, you need to cancel your subscription and start a new file by following the steps outlined in this article: Add a new company.

If you'd like to reuse your current lists after starting over, find out more about moving your lists to a new company from this article: Move your lists to QuickBooks Online.

Additionally, I've got this helpful link as your reference in managing your company's transactions, income or expenses, and other QBO entries: Get started with QuickBooks.
