Hi,How can i activate Debit Note Option?

Hello there. I'll make sure you'll be able to create a Debit Note in QuickBooks Online (QBO).

In QBO, creating a Debit Note doesn't need any activation. We can make one by just utilizing the Supplier Credit feature.

I'll be glad to assist you how:

1. Go to the +New icon.
2. Under Suppliers, select Supplier credit.
3. Choose your supplier from the Supplier drop-down button.
4. Depending on how you record purchases with this supplier, enter the Category details or Item details.
5. Enter the Date, Amount, and other information needed.
6. Hit Save and close.

You can refer to this article for the detailed step-by-step process and to know how to handle supplier credits in QBO: Enter supplier credits and refunds in QuickBooks Online.

Additionally, I've included an article that'll help you enter a prior balance for a customer that owes you money or a supplier you need to pay: Manage outstanding balances for customers and suppliers in QuickBooks Online.

If you require any additional assistance in handling supplier transactions in QBO, don't hesitate to reach us out again. Thank you, and have a great day!
