I’m here to share some information about GST e-invoicing. As of the moment, QuickBooks Online doesn't support this feature. To ensure that your invoices will be reported to the Invoice Registration Portal (IRP) of the GST, you may use a third-party application. You can visit our QuickBooks App Market or go to the Apps menu within your QBO account to find one:
Sign in to QuickBooks Online.
Select Apps from the sidebar menu.
Go to the Find Apps tab.
Enter a keyword in the search bar or click the Browse Category button to filter the results.
