Hi astein65,
I can see how helpful to be able to create a RCTI invoice for your business. Currently QuickBooks Online does not offer the RCTI feature. The suggestion provided by my colleague from the thread above is the work around on how you can record the transaction manually in QuickBooks.
You'll need to create an invoice for the customer side and an expense for the supplier/vendor. And then, once you're ready to pay you can create a journal entry to Accounts Receivable and Accounts payable. I'd recommend reaching out to your accountant to get more information on how you can journal the accounts to not mess up your books.
And I recommend checking in with the ATO to get more information about recording RCTI manually: https://www.ato.gov.au/About-ATO/Contact-us/.
Post again in the Community if you need more help with QuickBooks Online. I'll be around to help you!
