I passed an invoice for a customer on 1/3/23 for R600. The customer has decided to cancel class with me. I now have to cancel that invoice for! How do I cancel invoice?

Hello there, @hermina-andrade-. I'm here to help cancel an invoice in QuickBooks Online (QBO).

 You can cancel a customer's invoice by deleting it. I'd be happy to show you how:
 

1. In your dashboard, click the Sales tab.
2. Tap Invoices.
3. Select the invoice you want to delete.
4. Click the More tab, then hit Delete.
    

I've also included a few articles you can use to deliver invoices to customers and track payments:

• Different Ways to Send Invoices in QuickBooks Online
• Receive and Categorize Invoice Payments
   

Additionally, we can personalize your statement and other form types in QBO. For detailed steps, please check this page: Customize invoices, estimates, and sales receipts.

Please update me on how it goes after performing the options above by dropping a comment below. We'd be glad to answer them for you.
