Can we raise debit note

Hello vijaya-iengaust-

You can use the Adjustment note option to issue a credit to your customer. Let me share with you some information about when can we create an adjustment note in QuickBooks Online. 

• If your customer wants to immediately reduce their current open balance, use an adjustment note.
• Your customer can use their adjustment note as payment for an invoice. They can use all of their adjustment note or a portion of it.
• You can apply a adjustment note when recording payment for a customer’s invoice.
• Adjustment notes impact sales reports, even if you don't apply them to invoices.

To an adjustment note:

1. Click on + New.
2. Click on Adjustment note.
3. In the Customer dropdown, select the customer's name.
4. Enter the adjustment note details, such as the date and the amount. 
5. When you're done, select Save and close.

You can then apply the adjustment note to the open invoice of the customer through Receive payment option.
