Creating a credit note

Open the Invoice
Go to the Update Invoice page for the invoice you want to adjust.

Add a Credit Note
Click Waive or Credit Amount below the invoice totals (see highlighted section in the screenshot below). The button is greyed out when the invoice is still a draft or has nothing owing.

Enter the credit note details
Clicking Waive or Credit Amount will display a screen with the invoice amount automatically populated in the credit note line items.

4
Review the updated invoice
After saving, the invoice summary will update to include a credit note line as displayed in the following screenshot.

Email the Updated Invoice
Once the credit note has been applied, you can send the updated invoice to your client which will include the credit note amount.
