Adjustment note for GST

Hi.  My client issued an invoice several months ago without charging GST.

I contacted the customer and they were agreeable to pay the additional amount for GST and asked for an adjustment note to be issued for the GST only.


I created an adjustment note thusly-

Item sold X NEGATIVE Amount GST FREE

Item sold X Positive Amount GST

Please see attached screenshot.


Please can someone tell me why QB now showing this is a credit note and not a debit note to the customer, and more importantly how do I correct?  The customer has now paid the GST amount but I cannot settle in Debtors because is showing as negative in SalesScreenshot 2022-04-10 160133.png

Adjustment note for GST

Hello Skeksis,


If you wanted to apply GST on the invoice, it is best to edit the invoice to apply the GST code on them instead of creating an adjustment note. The adjustment note is best recorded if an item was returned by a customer and you need to reduce the invoice amount due.


To edit an invoice:


  1. Go to the Sales tab.
  2. Click on Invoices.
  3. Under the invoice list, locate the invoice and click on the drop down arrow under Actions column.
  4. Click on View/Edit.
  5. Make the necessary changes on the invoice like the GST code.
  6. Click on Save and close.

Once done, this should calculate GST on your invoice and then, you can then apply the payment the customer made for the GST to close off the invoice.

Adjustment note for GST

The original incorrect invoice was 18 months ago, editing the original invoice is not an option as it is a prior (closed) financial year.

Can you advise another method to correct this transaction?

Why does the software (incorrectly) record the transaction as a credit when it is clearly a debit?


Adjustment note for GST

Thanks for your reply, Skeksis. 


Let me share with you some information when can we create an adjustment note in QuickBooks Online. 


  • If your customer wants to immediately reduce their current open balance, use a 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.


For GST only transaction, you can create an invoice and enter the items with positive and negative amount and one of it has a GST and the other is GST-free or Out of scope (similar entry as the adjustment note you've created above). 


I would recommend to consult an accountant on how you can record best the adjustment note for GST only in QuickBooks Online. Doing so, your sales and/or tax reports are recorded correctly.
