How to invoicev nos show in credits notes

Hi there, @sharma_engg01. 

Thanks for posting here in the Community. I'm here to help you create an invoice for your customers in QuickBooks Online. 

If you're trying to invoice a customer without applying the credit notes, you can turn off the credit note auto-apply feature. Here's how: 

1. Go to the Settings menu, then select Account and settings.
2. Click the Advanced tab.
3. Select Edit in the Automation section.
4. Uncheck the Automatically apply credits box.
5. Click Save, then Done.

You can now create an invoice like you normally do. However, if you want to link the credit note to the invoice, you can manually apply it. Here's how: 

1. Select + New, then select Receive payment or Receive invoice payment.
2. In Customer dropdown, select the customer.
3. Select the open invoice you want to apply the credit note to in the Outstanding Transactions section. 
4. Select the credit notes you want to apply in the Credits section.
5. Enter how much of the credit you want to apply for the open invoice in the Payment column.
6. Enter all necessary details to complete the form, including the Payment date.
7. Ensure that the total is correct after applying the credit note, then select Save and close.
