I'll provide insights into retrieving draft invoices in QuickBooks Online (QBO), Barry.

Currently, the program is unable to save invoice drafts. Once you've closed the Invoice page without saving it, there is no option to retrieve its details.

Moreover, I'm adding this article to help you personalize the appearance of your sales forms: Customize invoices, estimates, and sales receipts in QuickBooks Online.

You can always post a reply below if you have additional questions regarding invoices. We'll be happy to help. Take care.
